生化法处理煤气废水中试研究

Pilot-scale study on coal gasification wastewater treatment by biochemical process

通过对水解酸化-好氧两段生化法处理煤气废水中试试验研究,试验结果表明,在进水COD小于2500mg.L-1,NH+4-N小于150mg.L-1时,COD去除率可达到80%,NH+4-N去除率可达到50%,BOD去除率在96%以上。

A pilot - scale experiment on coal gasification wastewater treatment by biochemical process was conducted, the experiment results showed that when influent COD was below 2500mg·L^-1 and NH4^＋ - N of biochemical stage was below 150mg·L^-1, the COD removal efficiency could reach 80%, the NH4^＋- N removal efficiency could reach 50% and the BOD removal efficiency could reach 96% above.
