【摘要】 采用厌氧流化床工艺处理三唑磷农药废水,必须降低原水中NH₃—N含量,调整营养比例.当COD:N:P=（180～200）:5:1时,在中温厌氧消化条件下,COD含量可从4170mg/1降到2100mg/1,去除率约50%;沼气产率达到0.256m³/m³·d.因此,把厌氧处理作为好氧处理的预处理单元,能确保整个处理系统出水达标.更多还原

【Abstract】 When treating triamiphos waste water by anaerobic fluidized bed process the NH3-N content in raw waste water must be reduced and nutrition ratio be adjusted. While COD : N : P is (180-200) : 5 : 1 and anaerobic digestion under middle temperature COD concentration can be reduced from 4 170 mg/1 to 2 100 mg/1. The removal rate is about 50 % and the methane production reaches 0. 256 m3/m3 - d. Therefore taking the anaerobic treatmeat as pretreatment unit of aerobic treatment system can ensure the water discharged from the whole system reaches the discharge standard.更多还原
