摘要
通过对三种生化工艺处理处理煤气废水的比较,确定了水解酸化-好氧两段生物法处理煤气废水,并对该工艺进行了中试实验研究,实验结果表明,在进水COD＜2500mg/L,NH_3-N＜150mg/L时,COD去除率可达到80%,NH_3-N去除率可达到50%,BOD去除率在96%以上。
Involves an large-scale study for exploring a selealon of three treatments for gas wastewater. The hydrdytic acidification and aerobic biochemical treatment are determinde. Result of the study showed that average removal rate of COD and NH3-N as well as BOD are more than 80%. 50% and 96% respectiuely when COD of influents〈2500mg/L, NH3-N〈150mg/L.
