高压静电场处理污水的杀菌效果试验

Study on Disinfection Effect of High-voltage Electrostatic Field

以高压静电处理城市污水厂二沉池出水,并考察了它对污水COD、BOD、NH_3-N、NO_3-N、TOC和细菌总数的影响。结果表明,静电场对有机物及氨氮没有去除能力,却有较大杀菌消毒效果,细菌去除率达98％以上。

Effluent of municipal sewage from secondary clarifiers was treated by high-voltage electrostatic field has been studied. Water quality indexes, such as COD, BOD, NH3-N, NO3-N, TOC and total count were detected before and after treatment. The result showed that there was no change of these indexes except total count, and about 98% of bacteria being killed in electrostatic field.
