摘　　要：研究双铝电极电凝聚气浮强化一级处理城市污水的有效性和可行性.进行电解时间、电流密度、电解质等影响因素的静态试验,并通过动态试验,分析水力停留时间、电流密度、电流波形的影响,研究有机污染物去除特性.试验结果表明:COD、SS及色度去除率分别在75.11%、80%和80%以上,其COD、色度可达城镇二级污水处理厂二级标准,对处理小规模、分散性的城镇生活污水具有一定的推广价值.Present a study on the effectiveness and feasibility to intensity primary treatment of domestic sewage by electrocoagulation and electrofloatation with electrode structure form of bipolar aluminum electrodes. Static experiments are proceeded by changing electrolysis time and electric current density, and adding the electrolytes, and so on. Through mobile experiments, the relation between existent states of organic contamination and their removal characters are dealt with. The results of experiments indicate that the removed efficiencies of COD, SS and chromaticity of effluent are above 75.11%, 80% and 80% respective. This has definite recommendable significance for treating small scale and scattering domestic wastewater.
