固定化优势菌去除焦化废水中COD的研究

Study on Removing COD from Coke-plant Wastewater by Immobilized Advantage Bacterium

采用聚乙烯醇(PVA)-硼酸包埋固定化法,包埋经筛选出的优势菌,制成固定化优势菌胶片。研究了不同条件下(温度、pH等)优势菌对COD的去除效果以及与未添加固定化优势菌的处理工艺进行比较,并对优势菌在最优环境下的生存状态进行了测定和观察。

This research aimed at the immobilization process of advantage bacterium and removing COD from coke-plant wastewater by immobilized advantage bacterium.An immobilization system was obtained by entrapping cultivated activated sludge in mixed PVA gel.The influence factors of effectiveness such as temperature and pH were studied.The optimum living environment of advantage bacterium was measured and observed.
