摘　　要：应用瓦氏呼吸仪测定微生物耗氧量方法,研究添加玉米浸出液强化活性污泥系统处理焦化废水的效果。研究结果表明,系统耗氧量增加,相对好氧速率明显加快,B/C比值升高,反应1h后,比值达到0.46,难降解有机物得到一定程度降解,焦化废水生化处理效果得到加强。该类物质可用于提高工业废水的生化处理效果,节约污水处理厂的运行成本。The industrial wastewater has always lack of some nutrient elements, which lead to poor treating effect in activated sludge process. Such micronutrient elements as amino acids and vitamins in maize lixivium can promote the growth and metabolism of microorganism. In this work, the treating effect of the coking wastewater by activated sludge system strengthened with lixivium was studied. It was shown that oxygen consumption in system increased, relative aerobic rate speeded up obviously and BOD/COD values rose; after reacting for lh, the ratio reached to 0.46 and the substances which are difficult to degrade got degradation to a certain degree and the treating effect of the coking wastewater was strengthened. Such substances of maize lixivium can be used for improving the biochemical treatment effect for industrial wastewater and saving the operational cost for sewage treatment plant.
