Forecast and analysis of market size and development trend of China's environmental protection and water industry in 2021

With the advancement of industrialization, my country's industrial wastewater discharge has been relatively large. The construction of sewage treatment facilities lags behind, and industrial sewage is discharged without treatment up to the standard, resulting in the continuous deterioration of the water quality of natural water bodies and the serious pollution of water resources. Water pollution has become one of the important factors restricting the sustainable development of my country's economy and society.    Water resources are limited    The total amount of water resources in China is relatively high. Data shows that the total amount of water resources in China has increased from 2,796.2 billion cubic meters in 2015 to 3,096.3 billion cubic meters in 2020. Due to the large population of China, the amount of water resources per capita is relatively small. In 2020, the amount of water resources per capita in my country will reach 2,211 cubic meters. In the arid regions of northwest China, the amount of water resources per capita is even smaller. In recent years, the amount of industrial water and domestic water has been continuously increasing, but water resources are very limited, and the task of purification and treatment of sewage is very important. The sewage must be allocated and optimized for recycling.

Can hydrogen storage become the "stabilizer" of the power grid?

According to a report by the Voice of Economy of China Central Radio and Television "Tianxia Finance", hydrogen energy has ushered in a wave of deployment this year, and some photovoltaic companies have entered this field one after another. Compared with other energy sources, hydrogen energy is clean and environmentally friendly, with high energy density, and is regarded by some as the "ultimate energy source". However, in order to develop hydrogen energy on a large scale, there are still bottlenecks in the production, storage, transportation, and use of multiple links, a long industrial chain, and complex technology. Right now, the northern region is about to enter summer, and the power system is preparing for the peak of summer. As the installed capacity of power generation continues to increase, in recent years, the overall supply of electricity in my country has shown a pattern of oversupply. However, in the winter that has just passed, the phenomenon of power cuts reappeared in some places after many years. According to expert analysis, one of the reasons for this seemingly contradictory phenomenon is the rapid development of renewable energy sources such as photovoltaics and wind power. To support the development of renewable energy, it is necessary to minimize such fluctuations. Yu Zhuoping, director of the Expert Committee of China Hydrogen Energy Alliance and professor of Tongji University, said that on the power generation side, photovoltaic companies are currently exploring the use of hydrogen storage to optimize power supply. "The power grid hopes to have a stable power source. Hydrogen is now used as an intermediate carrier. The electricity that can be connected to the Internet is used to produce hydrogen. The electricity that cannot be connected to the Internet is actually converted into hydrogen energy and stored. This It can be done on a large scale." When the electricity load increases, it can operate in the reverse direction, using the stored hydrogen to generate electricity and supply power to the grid. In this way, renewable energy power generation becomes flexible and controllable, no longer "seeing the sky for food", and the pressure on the power grid will be significantly reduced. However, it is worth noting that there are currently no mature application cases for hydrogen storage in the world. Some experts have also questioned this technology. The biggest question is how high energy efficiency is when energy is switched back and forth between electricity and hydrogen energy. ?According to Zhou Zhensheng, CEO of the Hydrogen Energy Division of GCL Group, the energy efficiency is only 40% after a cycle from electricity to hydrogen to electricity. And currently in the field of energy storage, there are also models such as pumped storage and energy storage batteries. Taking energy storage batteries as an example, the entire process is charging and discharging, and the energy loss is only about 10%, which is significantly higher than hydrogen storage. However, Zhou Zhensheng said that compared with batteries, hydrogen storage also has unparalleled advantages. "General energy storage batteries, lithium batteries, the storage time is very short, at most one week, but hydrogen is not the same, a few years will work, this is a very important point. In addition, it can be reversed in the (grid) Basically, I think the fuel cell can be unrestricted. As long as there is hydrogen, it can be supplied indefinitely." In addition, the more power stored by the energy storage battery, the larger the space occupied, so it is not suitable for large-scale energy storage scenarios such as power stations. However, pumped storage needs to be close to the water source, and there are also conditions. In a comprehensive comparison, the potential of hydrogen storage is greater. In April, hydrogen storage ushered in policy support. The National Energy Administration issued the "Guiding Opinions on Energy Work for 2021", proposing that it should be demand-oriented and explore the research and demonstration applications of hydrogen energy storage and other innovative energy storage technologies. However, some insiders pointed out that to solve the problem of renewable energy consumption, it is not enough to increase energy storage facilities on the power generation side. Will hydrogen storage not be used and become a decoration? This is also the most worrying issue for photovoltaic and wind power companies. Yu Zhuoping believes that even if the power grid is not deployed, hydrogen storage will not be useless in the future. Yu Zhuoping said: "I even use renewable energy to produce hydrogen. I can't go online at all. If there is a lot of (electricity) in some places, and now it’s difficult to go online, I will immediately turn the generated electricity into hydrogen. Just store it and use it on the application side. This is a very good solution. So we say that hydrogen energy will promote the large-scale app

Sewage treatment: a fast-growing field of environmental protection and water affairs

Sewage treatment has been a key area of ​​my country’s ecological environment protection in recent years. The "14th Five-Year Plan" for key river basin water ecological environment protection work promotion meeting put forward "If there is a river, there must be water, if there is water, there must be fish, and if there is fish, there must be grass. , Can swim in the river” requirements. The "14th Five-Year Plan" will pay more attention to water ecological protection and restoration based on the improvement of water environment quality. Upgrading and upgrading is still the key work of the industry. In May 2020, the National Development and Reform Commission clearly promoted the utilization of wastewater resources, studied and promoted the drafting of guidelines and related implementation plans for the utilization of wastewater resources, and promoted the establishment of a "1+N" policy framework system for the utilization of wastewater resources. With the introduction of a series of favorable policies for the industry, the sewage treatment industry is expected to open up the space for rapid growth. Sewage treatment is an important part of the environmental protection water sector. It refers to the process of removing or reducing solid pollutants and organic pollutants in different types of sewage through professional treatment methods, so that the purified water can meet the requirements for reuse or discharge. At present, sewage treatment has been widely used in agriculture, petrochemical, medical, catering and other fields. Sewage treatment is located at the end of the entire water service industry and plays a vital role in the recycling of the water service industry. Only the good operation of the wastewater treatment stage can ensure the continuous circulation of the industrial chain. At present, my country's sewage treatment industry chain mainly consists of water treatment equipment, engineering construction, and operation services. The proportion of revenue in terms of revenue shows a pyramidal distribution, but in terms of gross profit margin, the further downstream, the higher the gross profit margin. Sewage treatment industry panorama: (Chart source: Ping An Securities) Sewage can be divided into production sewage, domestic sewage and polluted rainwater according to its source. Production sewage can be divided into industrial sewage, agricultural sewage and medical sewage, of which industrial sewage is the main one. At present, the treatment of industrial sewage and domestic sewage in the production sewage is the key target of the sewage treatment industry. Although the amount of industrial wastewater discharge has decreased in recent years, the total amount is still high. The top 4 industries with wastewater discharge volume are paper and paper products, chemical raw materials and chemical products manufacturing, textiles, coal mining and washing. In the selection of industries, the wastewater discharge of the four industries was 8.8 billion tons, accounting for 47.1% of the total wastewater discharge of industrial enterprises. Industrial wastewater is a technology-based industry due to its wide variety, large discharge volume, and many pollutant elements. It requires high technical level of sewage treatment plants, and the treatment processes of different industries are very different. Rural sewage treatment is still in its infancy, and treatment facilities are generally imperfect in the construction of plant networks. The sewage treatment rate in rural areas is only about 10%. A large amount of untreated rural sewage is directly discharged into the river system and becomes the main source of water pollution. The key to solving the dilemma of rural sewage treatment is to explore technologies that are high-efficiency, low-input, and low-operating costs, which are suitable for decentralized rural sewage treatment. At present, there are about 30 kinds of sewage treatment processes in China, and the top six sewage treatment processes are: oxidation ditch process, A2/O process, traditional activated sludge process, SBR process, A/O process and biological Membrane process. From the perspective of the development history of biological wastewater treatment, the biofilm method was born before the activated sludge method. Although the early biofilm method has the characteristics of high biomass, good purification effect and low energy consumption compared with the activated sludge method, Due to its low hydraulic load and organic load, its application in large-scale sewage treatment projects is limited. Therefore, currently domestic sewage treatment plants mostly use the activated sludge method and its derivative processes, such as: A2O process, SBR process, oxidation ditch process, AO process, etc. According to the forecast of China Water Network, the scale of my country's reclaimed water is expected to reach 85 million cubic meters per day in 2025. The total investment in the constru

Yantai, the first "trusted WLAN + smart substation" in Shandong Province, was completed and put into operation

On April 1, Shandong Province's first "trusted WLAN + smart substation" was completed and put into operation at 220 kV Wanhua Station in Yantai Development Zone. The site integrates a trusted WLAN network and intelligent inspection robots, mobile operations, small micro-weather stations and other business systems. Through a secure and trusted wireless WLAN private network, the above-mentioned business information is managed, analyzed and decided in a unified manner, and the operation of the substation is improved. The state's perception level and operation and maintenance efficiency ensure the safety of people and equipment, which greatly contributes to the construction of the intelligent IoT system of substations. During the "14th Five-Year Plan" period, smart grids have put forward higher demands for the application of new information and communication technologies, and the trusted WLAN network adopts China's self-developed WAPI technology, and the domestic cryptographic algorithm SM4 is used as the wireless security access standard. , Adopting an original ternary security architecture system, which is safer and more reliable than WIFI technology, and is especially suitable for industries with high confidentiality requirements such as electric power, railways, and aviation. After many studies and discussions, the State Grid Yantai Power Supply Company selected the 220kV Wanhua Station as the pilot application construction site in conjunction with the key project of the transformation of the auxiliary control system of the substation in 2021. By deploying a trusted WLAN network, it can effectively solve the problems of difficult access to wired communication and small coverage during the transformation of the auxiliary control system in the station, and realize the function of remote inspection and monitoring of the auxiliary equipment of the substation by the substation operation and maintenance personnel. Yantai Power Supply Company will continue to optimize the "trusted WLAN + smart substation" system, continue to strengthen cross-professional, cross-departmental joint collaboration and special research, promote the in-depth integration of production and research, and explore more pilot projects under the premise of ensuring equipment safety, personal safety and data security. Multi-trusted WLAN application scenarios have been implemented, forming a batch of solutions that can be promoted and applied, and quickly promoting the application process of "trusted WLAN + smart grid".
