Comprehensively promote clean production transformation or clean transformation, and basically complete the transformation tasks assigned this year.
Promote harmless sludge disposal Illegal sludge storage sites will be banned
Promote the construction of sewage treatment supporting pipe network and the reconstruction of rain and sewage diversion system. The village in the city, the old urban area and the junction between urban and rural areas should be fully covered as soon as possible. In new urban areas, the pipe network and sewage treatment facilities must be planned and constructed simultaneously with the urban development. To achieve rain and sewage diversion; urban sewage treatment plants have been built to strengthen operational monitoring, improve water collection and treatment rates, ensure stable operation, and exert pollution control effects; new urban sewage treatment plants must meet or exceed Class A Discharge standards. Eligible wastewater treatment plants at or above the county level will gradually construct tailwater wetland projects to further purify the effluent quality of wastewater treatment plants.
Promote the harmless disposal of sludge. The sludge produced by sewage treatment facilities must be stabilized, harmless, and recycled. Sewage sludge that does not meet the standards for heavy metals and other pollutants should not be allowed to enter the cultivated land. Illegal sludge storage sites should be banned. ; Strengthen the supervision of facility operation and improve the level of sludge treatment and disposal in urban sewage treatment plants.
