摘要/Abstract

摘要： 通过试验研究了硅藻土与FeCl₃组配处理含Pb²⁺废水。结果表明，当进水中Pb²⁺浓度为52.4 mg/L，采用硅藻土与FeCl₃配比（质量比）为6∶1，硅藻土投量为70 mg/L，控制pH在7.0～8.0、搅拌转速在120～140 r/min之间,沉淀80 min后出水中Pb²⁺可达标排放。该方法操作方便，投资少，具有良好的推广应用前景。

Abstract: Experimental research was made on the treatment of Pb²⁺- containing waste water by combination of diatomite and FeCl₃. The results show than when the water contains 52.4 mg/L , the water can reach the standard for Pb²⁺ content for discharge after the treatment at the conditions of a ratio (mass ratio)of diatomite to FeCl₃ of 6∶1, diatomite dosage of 70 mg/L, pH control at 7.0~8.0, agitation speed of 120~140 r/min and 80 min precipitation. Easy to operate and needing only a small investment, the method has good application prospect.
