| 摘 要： | 腈纶废水中含有氰化物、单体聚合物等有毒有害物质,碱性氧化法、酸性回收法等处理含氰废水,难以达到国家排放标准。上海某腈纶厂采用硫氰酸钠一步法和二步法湿纺工艺生产腈纶,废水处理采用＂加药混凝沉淀法＋生物接触氧化法＂,氰化物、氨氮、COD、BOD5去除率分别为94.5%、89.9%、88.2%、97%,达到污水综合排放一级标准。

| Abstract: | Acrylic wastewater contains cyanide,monomer polymer which are toxic or harmful.It is difficult to meet the national emission standard when the cyanogens-contained waste water is purified by alkaline oxidation and acid recycling.A certain Acrylic Plant of Shanghai produces Acrylic Fiber by NaSCN wetspinning technology including one-step and two-step processes,with wastewater treatment by ＇＇the way of coagulating sedimentation ＋ biological contact oxidation processes＇＇,and the removal rate of Cyanide,ammonia nitrogen,COD,BOD5 are respectively 94.5%,89.9%,88.2% and 97%,which comes up to the first-grade of integrated wastewater discharge standard. |
