焦化废水处理中活性污泥的基础研究

从焦化厂处理焦化废水的活性污泥中分离出３６５株细菌，分别属于１０个细菌属，其中Ｇｒａｍ负反应菌占总菌数的５９．４６％。黄杆菌属、产碱菌属和芽胞杆菌属为该活性污泥中的优势种群。从上述菌株中筛选到两株对苯酚有较强去除率的细菌（假单胞菌属Ｐｓｅｕｄｏｍｏｎａｓ ｓｐ．４００３和不动杆菌属Ａｃｉｎｅｔｏｂａｃｔｅｒ ｓｐ．３００８），在处理焦化废水时添加５ｍｇ／Ｌ的葡萄糖，可提高该菌对废水中挥发性酚的降解

A BASIC RESEARCH ON THE ACTIVATED SLUDGE IN THE TREATMENT OF COKE-OVEN LIQUIDS

bacterial strains were isolated from the activated sludge in the rreatment of coke oven liquids.They were identified and belong to 10 genera.Gram negative strains make up 59.46% of all strains.Flavobacterium,Alcarligenes and Bacillus are dominant benera in the activated sludge.Among the strains screened,Pseudomonas sp.4003 and Acinetobacter sp.3008 showed an efficient capacity of breaking down phenol.By adding only 5 milligrams of glucose perlitre to the coke oven liquids inoculated with Pseudomonas sp.4003,the degradation of phenolic substances could be significantly accelerated.
