焦化废水降解的生物强化条件研究
A study on bioaugmenting condition of coke-plant wastewater degradation
【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、Fe3+、Mg2 +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 Fe3+配合 ,可使焦化废水降解率提高 1 0 % ,使用等体积蒸馏水稀释的焦化废水降解率提高 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%.
【Key words】 coke plant wastewater; nutritious augmenting material; biodegradability; COD(chemical oxygen demand);
