摘　　要：采用聚乙二醇和海藻酸钠作为复合载体,对硝化细菌Y1菌株进行包埋固定化,并测试两种载体浓度、交联剂浓度及交联时间等对固定化小球性能的影响。结果表明,菌株的最佳固定化条件为:聚乙二醇浓度8%,海藻酸钠浓度3%,CaCl2浓度3%及交联时间20 h。Using PEG and SA as mixed carrier materials to immobilize nitrifying bacteria, and test affects of two kinds of carrier concentration, cross-linking agent concentration and cross-linking time to perform- ance of immobilized pellets. The result showed that when PEG concentration was 8% ,SA was 3%, CaCl2 was 3% ,and cross-linking time was 20 h,immobilized globule was the best condition.
