摘要
着重研究电凝聚技术和电气浮技术处理城镇生活污水的有效性和差异性.通过改变影响因素,进行试验研究,从而对电凝聚技术和电气浮技术处理城镇生活污水的效果进行对比.电凝聚和电气浮对COD去除效果较高,其出水COD值可达城镇二级污水处理二级标准;而电气浮对SS和色度的去除效果比电凝聚差.采用电凝聚技术处理小规模、分散性的城镇生活污水具有一定的推广价值.
The availability and feasibility for municipal domestic sewage treatment by electrocoagulation and electroflotation were studied in this paper. Treatment results of municipal domestic sewage by electrocoagulation and electroflotation through changing factors were compared. Higher COD removal efficiency is achieved by electocoagulation and electroflascation. The effluent COD value could reach the secondary standard of towns＇ secondary sewage treatment. The SS and color removal by electroflotation were worse than by electrocoagu-lation. It had some promotional value that small-scale, decentralized nature of municipal domestic sewage were treatmented by electrocoagulation.
