干法腈纶废水处理是废水处理上的一大难题,由于其生化性差,难生物降解物质含量高,直接影响废水的达标排放.根据该水质特征,选用了先进的前处理技术"过电位三维电解技术"和"美境高效复合微生物菌种"组成"混凝-过电位三维电解-兼氧-好氧"工艺对其进行处理试验,并取得了较满意的效果.COD从1 585mg/L降到95mg/L,去除率为94.0%,NH3-N从65 mg/L降到2 mg/L,去除率为96.9%,出水达到国家一级排放标准.%The treatment of dry-spun acrylic fibre wastewater is a big problem in the wastewater treatment field,main-ly because of its poor biodegradability. It contains many refractory biodegradable materials,and this directly affects the discharge standard of wastewater. According to the water quality, the advanced technology of "coagulation-the potential three-dimensional electrolysis-facultative aerobic-aerobic" composed of advanced pretreatment technique which is "the potential three-dimensional electrolysis technology" and "Meijing efficient compound microbial strains" have been studied, and satisfactory results finally is achieved. The COD reduces from 1 585 mg/L to 95 mg/L, and its removal rate is 94.0%. NH3-N drops from 65 mg/L to 2 mg/L, its removal rate is 96.9%. The effluent accords with the first grade of national discharge standards.
