So it is used for the target contamination to be degraded by microorganism, electrochemical oxidation and bio-electro reactor in this paper. We found out a economical, efficient and non-polluted methods for the treatment of wastewater from vanillin production plant. The results indicate that there are a lot of special microbes and bacteria eating 4-amino-dimethyl-aniline hydrochloride in the activated sludge after 20 days′ incubation, at the same time, a stable bio-filmed electrode was formed. Under the condition of 25 ℃, pH=6—7. The use of bio-electro reactor not only increased the biodegradability and decreased the electrical energy consumption, but also solved the problem which the second pollution of organic compounds containing chlorine in the process of indirect electrochemical degradation on the organic pollutants.展开更多
本文介绍了四种微生物膜制备的 BOD 电极及其测定废水 BOD 的试验情况。结果表明,电极对 BOD 标准物质的线性响应范围为10～60毫克/升,达到平衡时间为4分钟(对低限浓度溶液)到7分钟(对高限浓度溶液),连续稳定的工作寿命在20天以上;用该...本文介绍了四种微生物膜制备的 BOD 电极及其测定废水 BOD 的试验情况。结果表明,电极对 BOD 标准物质的线性响应范围为10～60毫克/升,达到平衡时间为4分钟(对低限浓度溶液)到7分钟(对高限浓度溶液),连续稳定的工作寿命在20天以上;用该电极和 BOD_5标准法对照测定7种废水的BOD 值,测足结果的相关性较好,但电极法的测定速度比标准法快百倍以上,故具有较大的应用价值。展开更多
