摘　　要：[Objective] The aim was to study the pretreatment effect of herbicides production wastewater by different types of micro-electrolysis filler.[Method] The research performed comparison on the effects of three types of micro-electrolysis filler treatment of pesticide wastewater by changing the role of time and p H.[Result] The results showed that the best treatment effect was spherical packing,followed by tooth filler;poor treatment effect and easy to harden were iron shavings.With pH of the influent of 2 and reaction time of 160 min,the removals of CODcr and chromaticity which was with spherical packing reached 24.79% and 97.5%;the removals of CODcr and chromaticity which Dentate micro-electrolysis filler treated reached21.74% and 93.75%.With pH of the influent at 3 and reaction time of 120 min,the removal of CODcr and chromaticity which was treated with iron ingot reached13.59% and 87.5%.[Conclusion] By comparison analysis,the spherical packing is better suited to handle wastewater.[Objective] The aim was to study the pretreatment effect of herbicides production wastewater by different types of micro-electrolysis filler.[Method] The research performed comparison on the effects of three types of micro-electrolysis filler treatment of pesticide wastewater by changing the role of time and p H.[Result] The results showed that the best treatment effect was spherical packing,followed by tooth filler;poor treatment effect and easy to harden were iron shavings.With pH of the influent of 2 and reaction time of 160 min,the removals of CODcr and chromaticity which was with spherical packing reached 24.79% and 97.5%;the removals of CODcr and chromaticity which Dentate micro-electrolysis filler treated reached21.74% and 93.75%.With pH of the influent at 3 and reaction time of 120 min,the removal of CODcr and chromaticity which was treated with iron ingot reached13.59% and 87.5%.[Conclusion] By comparison analysis,the spherical packing is better suited to handle wastewater.
