通过小试、中试 ,研究了ClO2 对污水厂二级出水消毒、脱色、絮凝的影响 ,得出消毒脱色的最佳浓度及接触时间 ,并利用其微絮凝作用 ,在投加絮凝剂PAC之前投加ClO2 ,可有效地去除COD。
The effects of ClO2 on the secondary effluent disinfection, decolorization and flocculation of wastewater treatment plant were studied through small test and pilot test. The optimum concentration and contact time of disinfection and decolorization were obtained and its micro-flocculation was used. Before adding flocculant PAC Add ClO2, can effectively remove COD.
