依据太湖水体氮污染的特点 ,设计应用低温辐射技术引导玻璃态单体丙烯酸羟乙脂 2 - Hydroxyethyl acrylate(HEA)与聚乙二醇二甲基丙烯酸脂 Polyethylene glycol dimethacrylate(14G)制备高分子载体 ,并使用增殖细胞技术固定化硝化 -反硝化菌净化湖水 .研究结果表明 ,富营养化湖水经过固定化硝化 -反硝化菌 SBR工艺净化后 ,总氮下降 70 % ,氨氮下降 84 % ,CODCr下降 6 8% ,出水水质得到明显改善 .研究结果还表明 ,固定化硝化反硝化菌系统的最适反应温度为2 8℃ ,溶解氧浓度对总氮的去除率有一定的影响 ,固定化菌在低温条件下表现出明显的耐受性 .
According to the characteristics of nitrogen pollution in Taihu Lake, a low temperature radiation technology was used to guide the glassy monomer 2 - Hydroxyethyl acrylate (HEA) and polyethylene glycol dimethacrylate (14G) And purified nitrifying-denitrifying bacteria by using proliferating cell technology to purify the lake.The results showed that the total nitrogen decreased by 70%, the ammonia nitrogen decreased by 84% and the CODCr decreased by 6% after the eutrophication of the lake was purified by the immobilized nitrification-denitrification bacteria SBR 8%, water quality has been significantly improved.The results also show that the optimum reaction temperature of immobilized nitrification and denitrification bacteria system is 28 ℃, dissolved oxygen concentration has a certain impact on the total nitrogen removal rate, immobilized bacteria at low temperature Under conditions show obvious tolerance.
