摘　　要：煤气是一种清洁的燃料。然而,在煤气化生产过程中也产生了大量废水。生物降解目前是煤气化废水治疗的主要方法。由于煤气废水对微生物有较强的毒性和抑制性,生物学的技术提高是特别必需的。采用厌氧-好氧工艺,接种焦化厂厌氧池和好氧池成熟污泥,经驯化,通过对废水COD去除率的测定,结果显示,厌氧降解实际废水试验中,9天后COD去除率能达到72%以上;好氧降解水解出水试验中,7天后COD去除率能达到80%以上。Coal gas is a kind of clean fuel. However,a large amount of wastewater is also produced in the process of coal gasification. Biodegradation is the main method for coal gasification wastewater treatment at present. As the wastewater have toxicity to microorganism,biological enhancement technology especially aiming is particularly necessary. This study adopts oxygen-friendly oxygen craft,inoculates a burnt turn factory to be tired of oxygen pond and friendly oxygen pond mature and dirty mire,after taming to pass the measurement to clean the rate to waste water COD,Show that,being tired of oxygen declines to solve actual waste water to experiment as a result medium,after 9 days,COD clean a rate and can attain above 72%; The friendly oxygen declines solution water to solve a water to experiment medium,after 7 days,COD clean a rate and can attain above 80%.
