不同微生物菌剂对黑臭水体水质改善的试验研究

Experimental Study on Water Quality Improvement of Malodorous Water Using Microbial Agents

通过小试试验对比研究了5种微生物菌剂对于黑臭水体水质的改善效果,结果表明:3#菌剂对COD的去除能力最强,对COD去除率为45.90%(由110 mg/L降至59.50 mg/L),对氨氮去除能力最强的为4#菌剂,去除率为88.65%(由4.0 mg/L降至0.45 mg/L),3#菌剂的TP去除效果明显强于其他4种微生物菌剂,去除率最高为63.42%(由5.82 mg/L可降至1.95 mg/L);其中2#微生物菌剂吨水处理成本最低,为20.1元/m^(3)。

The performance of five microbial agents on the water quality improvement of malodorous water was investigated.The results showed that the highest removal efficiency of COD was 3#microbial agent,with a removal efficiency of 45.90%(from 110 mg/L to 90 mg/L).Theammonianitrogenremoval efficiency of 4#microbial agent was better than the other four agents and reached 88.6%(from 4.0 mg/L to 0.45 mg/L).The total phosphorus removal efficiency of 3#microbial agent was better than the other four agents and reached 63.42%(from 5.82 mg/L to 1.95 mg/L).The cost for per ton water of 2#microbial agent was the lowest,which was 20.1 yuan/m^(3).
