【摘要】 研究了从炼焦废水生物处理系统中分离出的PSB菌对炼焦有机废水的静态处理及动态处理试验,同时对PSB降解有机污染物的机理进行了探讨.结果表明,在pH为7及有氧条件下,PSB对炼焦有机废水有较好的处理效果,其有机物去除效率基本都在90%以上,脱酚效率达96%以上,氰化物去除率高达92%,氨氮去除效果在68%以上.更多还原

【Abstract】 The static treatment of coking wastewater by photosynthetic bacteria（PSB） which is separated from biological treating of coking wastewater are studied.The mechanism of degrading organic pollutants by PSB is studied.The results shows that the effect to most of coking wastewater is better by PSB.The optimum condition is pH=7 and on the condition of oxygen,the removal rate of organic matter is above 90%,the effect of phenol is above 96%,the effect of cyanide is above 92% and the effect of NH₃-N is above 68%.更多还原
