摘要
纺织印染助剂生产废水表面活性剂及乳化剂、氨氮、有机胺和有机物的含量较高,难降解物质多,水质水量波动大。采用调节池-加药气浮池-厌氧水解池-悬浮生物滤池(内分脱碳区、亚硝化区和硝化区)-沉淀池的组合工艺,在进水COD平均为4 284 mg/L,水解酸化后NH3-N质量浓度平均为184 mg/L的情况下,出水COD平均为273 mg/L,去除率达到93.6%,出水NH3-N质量浓度平均为9.6 mg/L,去除率达到94.8%,达到入管排放标准。
Textile printing and dying additive produce wastewater was characterized as high concentration of surfactant and emulsifier, ammonia nitrogen, organic amine, refractory compounds, which had a lot of refractory material and great fluctuation in water quality and quantity. By adjusting tank-eoagulative fioatation tank-anaerobic hydrolysis tank-suspended biological filter （decarburized zone, nitrosation zone, nitrification zone） -sedimentation tank combined process ,when the average influent COD was 4 284 mg/L and NI-13-N mass concentration after hydrolytic acidification was 184 mg,/L, the average effluent COD was 273 mg/L with COD removal rate of 93.6% and NH3-N concentration was 9.6 mg/L with NH3-N removal rate of 94.8%, the effluent index reached the standard of drainage network.
