摘　　要：利用4种不同成分的培养基从活性污泥中共分离出39株菌株,通过考察培养条件最终在4种培养基中各筛选得到一株具有较高絮凝活性的菌株,分别命名为A11,B6,C5,D6;同时考察了絮凝剂用量及助凝剂CaCl2的投入量对絮凝效果的影响,结果表明:A11絮凝剂投加量在0.2mL,CaCl2用量在0.8mL;B6絮凝剂投加量在0.2mL,CaCl2用量在1.0mL;C5絮凝剂投加量在0.25mL,CaCl2用量在1.0mL;D6絮凝剂投加量在0.15mL,CaCl2用量在1.0mL;分别具有良好的絮凝效果。Total isolation of 39 strains from activated sludge use of four different components of culture medium,by examining cultural conditions in the final in four media filter received a high flocculating activity of strain,were named A11,B6,C5,D6;Also investigated flocculant coagulant dosage and the amount of CaCl2 into effect on the flocculation,The results showed that： A11 flocculant dosage in 0.2 mL,amount of CaCl2 in 0.8 mL;B6 flocculant dosage in 0.2 mL,amount of CaCl2 in 1.0 mL;C5 flocculant dosage in 0.25 mL,amount of CaCl2 in 1.0 mL;D6 flocculant dosage in 0.15 mL,amount of CaCl2 in 1.0 mL;With good flocculationeffect respectively.
