According to the Statistical Yearbook of Urban Construction of The Ministry of Housing and Urban-Rural Development of China, China's sewage discharge increased year by year from 2011 to 2019. In 2019, China's urban sewage discharge has reached 55.5 billion tons, increasing the pressure of sewage treatment. Moreover, due to the further approach of the "dual carbon" target, the low-carbon transformation of sewage treatment industry cannot be stopped.
In this situation, the industry said that the municipal sewage treatment industry energy consumption, 2020 alone, the entire industry electricity consumption has been more than 18 billion degrees. It is not only the biggest energy consumption in the environmental protection industry, but also plays a "certain role" in the total energy consumption of the society. Therefore, in order to upgrade iteratively and boost the achievement of the "double carbon" goal, the low-carbon development route of municipal sewage treatment industry has been finalized.
Since then, the industry began to wade in the water to find solutions, explore and find new results.
Recently the brewery for sewage treatment plant supplementary carbon source becomes hot, the topic of environmental protection also reported the event online, henan luoyang ecological environment bureau of water ecological environment coordinate breweries and sewage treatment plant sewage collaboration problem is in the henan environmental system service day activities the first service enterprise ten typical cases. The cooperation between sewage plant and brewery is facilitated and guided by the environment department. It is understood that under this mode, both sides take what they need and have achieved significant economic benefits. Although the collaborative treatment mode of brewery and sewage treatment plant is in pilot operation, there are still some blocked points, but it can be seen that the trial and error link will eventually become a valuable experience on the road to the success of municipal sewage treatment low-carbon.
In addition, China's first low-carbon group standard in the field of sewage treatment, the Technical Specification for evaluation of Low-carbon Operation of Sewage Treatment Plants, has been released recently and will come into force on July 1 this year. The first low carbon group standard in the field of sewage treatment is targeted at sewage treatment plants, which can be seen in the low-carbon upgrading capacity of sewage treatment. Municipal sewage as the main part of sewage treatment, but also to low carbonization as the main means of development. This standard from the sewage treatment process carbon emission intensity accounting method, low carbon operation evaluation content and other aspects, provides an important method basis for the low carbon behavior of sewage treatment plants, but also for municipal sewage treatment to send a "reference scheme".
China Water network has also given suggestions on the low-carbon transformation development of municipal sewage treatment industry. For example, to strengthen the use of heat energy in China's municipal sewage treatment industry, to improve the operation of China's municipal sewage treatment industry energy-saving effect, promote China's municipal sewage treatment industry solar panel laying power generation.
Of course, the above suggestions also need to pass the test of time, phased completion. Based on the current situation, it is still key to formulate the specific target task and operation mechanism of low carbonization for municipal wastewater treatment industry.
Chang Jiwen, deputy director of the Resources and environmental Policy Institute of the Development Research Center of The State Council, said that in recent years, some municipal sewage treatment long in economically feasible conditions under the first trial, exploring sewage energy utilization, sludge thermal energy utilization, enterprise operation energy saving and photovoltaic power generation, has achieved preliminary results. Would like to believe that it will not take long, municipal sewage treatment low-carbon path will be clear.
