The “Organic Sulfur Pesticide Industrial Water Pollutant Emission Standards†drafted and prepared by the Ministry of Environmental Protection Technology Standards Division, Shenyang Shenyang Research Institute of Chemical Industry and the Chinese Academy of Environmental Sciences began to solicit comments from the industry. The work will be completed in May. End on the 15th.
According to the characteristics of the organic sulfur pesticide industrial production process and treatment technology, this standard specifies the control items and emission limits for water pollutant emissions in the production process of the organic sulfur pesticides of the Dyson and Nemicide toxin series. Emission management of water pollutants from sulfur pesticide production enterprises.
It is understood that the standards of the set of the requirements of the series of organic sulfur pesticides refers to the dithiocarbamate compounds such as mancozeb, zinc zearalenium, metsylamine, mannose, etc., Nereis toxin series organic sulfur Types of pesticides refer to insecticides such as dimehypotoxic insecticides, insecticides, and carrageenans.
According to regulations, existing enterprises will implement the following water pollutant emission limits from January 1, 2009 to June 30, 2010: H is 6-9; chemical oxygen demand (CODCr) ≤ 150m#L; Five days of biochemical oxygen demand ≤ 30mg / L; suspended solids ~ <70mg / L; total phosphorus ≤ 0.5mg / L; total nitrogen ≤ 15mg / L; ammonia nitrogen ≤ 15mg / L; chromaticity (dilution multiple) ≤ 50; The Dyson series has total manganese ≤ 2ms/L, total zinc ≤ 2mg/L, ethylenethiourea ≤ 0.2mg/L, and silkworm toxin series total cyanide ≤ 0.5mg/L, which can absorb organic halides (AOX, Calculated with C1) ≤ 1mg/L; Reference drainage of unit product: Senson series sodium process ≤ 70m3/t, Ammonia process ≤ 80m3/t, Production insecticide list (double) ≤ 75m3/t, Production of killing dandan ≤ 80m3 /t.
The existing companies have implemented the following stricter water pollutant emission limits as of July 1, 2010 and new enterprises since July 1, 2008: Chemical oxygen demand ≤ 100mR/L; Biochemical oxygen demand on the 5th ≤ 20mg/L; suspended solids ≤ 50mg/L; chroma (dilution multiple) ≤ 30; dexamethasone total manganese ≤ 1mg/L, total zinc ≤ 1mg/L, ethylenethiourea ≤ 0.05mg/L; Nereis Toxin series total cyanide ≤ 0.4mg/L; reference drainage of the unit product: SENSEN series ≤55m3/t, production insecticide list (double) ≤60m3/t, and production of killing dandan ≤60m3/t.
