| 摘 要： | 通过微生物呼吸耗氧量的测定和摇床模拟降解，试验了葡萄糖、尿素、葡萄糖复合物等营养物质、无机盐作为营养强化基质和不同废水浓度对焦化废水降解的影响。试验结果表明：葡萄糖、牛肉膏、Ｆｅ＾３＋、Ｍｇ＾２＋等能提高活性污泥对焦化废水降解的能力；将废水进行适当稀释也能促进其降解；葡萄糖和Ｆｅ＾３＋配合，可使焦化废水降解率提高１０％，使用等体积蒸馏水稀释的焦化永降解率提高３３％。

| Abstract: | A study of the influence on biodegradation of coke plant wastewater, with a series of nutrition and inorganic salts as augmenting materials and in different concentrations, through measuring AOCC and COD degradation. Results show grape sugar, Fe 3 and Mg 2 can raise degradability to coke plant wastewater of activated sludge and proper dilution to coke plant wastewater can promote the degradation. Grape sugar and Fe 3 together causes degradation rate of coke plant wastewater to increase by 10% and wastewater diluted to twice of its volume by 33%. |

| Keywords: | coke plant wastewater nutritious augmenting material biodegradability COD(chemical oxygen demand) |
