Abstract: When talking about groundwater pollution prevention and control measures at the executive meeting of the State Council held on the 24th, it was clearly proposed to increase the urban sewage treatment rate and reuse rate. According to the reporter’s understanding, the sewage treatment support policy will be gradually introduced. This means that the sewage treatment industry that has passed the “Eleventh Five-Year” golden cycle continues to “have a play” during the “Twelfth Five-Year Plan” period.

The huge demand for production capacity According to data from the Ministry of Environmental Protection, 90% of China’s urban groundwater suffers from pollution from organic and inorganic toxic and harmful pollutants. In addition, the survey conducted by the Ministry of Land and Resources in recent years shows that 40% of the city's groundwater quality is still deteriorating. According to industry estimates, during the “Twelfth Five-Year Plan” period, wastewater treatment capacity needs to increase by 67% to meet wastewater treatment needs. The huge demand gap determines that sewage treatment will continue to receive policy support.

The State Council executive meeting proposed that the urban pollution that affects groundwater must be strictly controlled. Reduce the urban living pollution load, promote the transformation of the pipe network system, improve the urban sewage treatment rate and reuse rate, and strengthen the construction and treatment of landfills.

Groundwater is an important source of water for our country's living, industry, and agriculture. However, due to the increased pollution of surface water, the quality of groundwater is also deteriorating. According to the data provided by the Ministry of Environmental Protection, 90% of China’s urban groundwater is subject to organic and inorganic toxic and hazardous pollutants. And this situation is still deteriorating. According to the survey conducted by the Ministry of Land and Resources in recent years, 40% of the city's groundwater quality is deteriorating.

The aggravation of groundwater pollution is related to the low rate of urban sewage treatment. The data shows that the sewage treatment rate in China at the end of 2009 was only 73%, and the goal this year is to reach 80%. Even if this year reaches the target, there is still a big gap between the sewage treatment rate of 90% and the developed countries. According to industry estimates, during the “Twelfth Five-Year Plan” period, wastewater treatment capacity needs to increase by 67% to meet wastewater treatment needs.

The special plan will be submitted for approval within the year for the prevention of groundwater pollution, etc. Sewage treatment will continue to receive policy support. According to the reporter’s understanding, the “National Urban Wastewater Treatment and Recycling Facilities Construction Plan (2011-2015)” and “National Planning for the Construction of Urban Domestic Garbage Harmless Treatment Facilities (2011-2015)” have been included in the “Ten The overall plan for the special plan submitted to the State Council for examination and approval during the second five-year period will be formally submitted for approval within the year.

According to the above two plans, during the “Twelfth Five-Year Plan” period, the total investment in urban sewage treatment, including the central government, local governments, and individuals, reached 450 billion yuan. A report recently released by the Environmental Protection Institute of the Ministry of Environmental Protection predicts that the investment in the treatment of urban domestic sewage and industrial wastewater will increase substantially in the next five years. It is expected that during the "12th Five-Year Plan" period, China's cumulative investment in wastewater treatment will reach 1.06 trillion yuan.

In addition, according to the reporter, in order to increase the intensity of sewage treatment, in the next five years, China will also appropriately increase the urban wastewater treatment charges and discharge charges, and promote the use of ammonia and other major pollutants for the discharge of pollutants.

According to Yu Shufan, deputy director of the Department of Science and Technology Standards of the Ministry of Environmental Protection, the first major area of ​​China's environmental protection development in the "Twelfth Five-Year Plan" is sewage treatment. Specifically, it includes nitrogen and phosphorus removal, upgrading of existing sewage treatment plants, construction of sewage treatment plants in small and medium cities, and industrial wastewater treatment.
