043 mg/L after treating by setting process with saturated lime water,it fully attained to or below the demand of the level of total chromium≤1.
经采用饱和石灰水沉淀法处理后 ,总铬含量降低至 0 0 43mg/L ,完全达到或低于国家污水综合排放标准 (GB 8978 88,总铬≤1 5mg/L)。
The papallel experi- ments optimizes and screens the amount and conditions of clarification limewater and the results show:the removal rate of COD_(Cr,ammonia nitrogen and heavy metals is highest under conditions of pH about 9 and the dosage of saturated clarification limewater about 3%.
