好氧活性污泥处理含氰废水的试验研究

摘要

Based on the degradation of cyanide-containing wastewater tests with aerobic activated sludge under different conditions, and the suitable conditions for aerobic microbial degradation of cyanide were explored; Experimental results show that the aerobic activated sludge microbial degradation effect of the cyanide changes with conditions such as pH,temperature,dosage of glucose,beef extract and sludge. Meanwhile,the influence of environment to aerobic microbial degradation of cyanide was also explored.%基于含氰废水在不同条件下的好氧活性污泥降解试验,针对好氧微生物降解CN-的适宜条件进行了试验研究.试验结果表明,当pH值、温度、葡萄糖投加量、牛肉膏投加量、好氧活性污泥投加量等试验条件发生变化时,活性污泥中好氧微生物对氰化物的降解效果也相应产生变化.同时,也考察了环境改变对好氧微生物降解氰化物的影响,提高了氰化物的降解效果.
