摘要
采用电凝聚对厨房废水进行处理。通过改变电流密度、电解时间、沉淀时间等条件 ,进行了对废水中的COD ,浊度 ,NH3-N ,油 ,TP去除率的试验研究。当COD为 2 2 6 4mg/L ,油 15 5 4mg/L ,浊度 330 3NTU ,NH3-N 4 5mg/L ,TP 2 1 36mg/L时 ,在电流密度 2 0A/m2 ,沉淀时间 15min ,电解时间 10min的条件下 ,COD和氨氮去除率接近 70 % ,油的去除率达 90 %以上 ;
The removal rates of COD, turbidity, NH 3-N, oil and TP from kitchen wastewater by electro coagulation process were researched experimentally. The influence factors of galvanic density, electrolysis duration and precipitating time are investigated. In case when the concentrations in raw wastewater are 2 264 mg/L, 155 4 mg/L, 330 3 NTU and 45 mg/L for COD, turbidity, NH 3-N, oil and TP respectively, under condition of galvanic density 15~20 A/m 2, precipitating time 10~15 min and electrolysis duration 10 min, removals of 70%, 70%, 90%, 99% and 99% for COD, NH 3-N, oil, TP and turbidity respectively have been obtained.
