摘要
采用生物强化技术,即利用从废水中分离、筛选出的降解丙烯腈与总氰的特效菌株,使化纤废水加营养盐的培养基中丙烯腈降解率达98.7%,总氰降解率达84%.将分离到的特效菌株进行混合培养,其降解丙烯腈与总氰的最佳体积比为1.0:(1.5～2.0).使用该技术不必改变化纤废水处理场原有工艺.
The technology enhanced by two kinds of special bacteria strains isolated and screened from wastewater was used in the degradation of acrylonitrile and total cyanide in nutrients -added chemical rider wastewater. The removal rates of acrylonitrile and total cyanide are 98.7% and 84%, respectively. The best volume ratio of the two kinds of culture mediums is 1.0 ： （ 1.5 - 2.0 ）. It is not necessary to change the original wastewater treatment process for using the bioenhanced technology.
