复合微生物菌剂及其附着载体对黑臭水体试验的研究

Research on Compound Microbial Agent and Its Attachment Carrier on Black and Smelly Water Body

试验研究了不同配比的复合微生物菌剂附着在载体上对黑臭水体水质的改善效果。结果表明:3#试验组对COD的去除能力最强,可使COD浓度由1992 mg/L降至637 mg/L,去除率达68.1%;对氨氮去除能力最强的为1#菌剂,其氨氮浓度可由215 mg/L降至38 mg/L,去除率最高为82.4%;2#菌剂的TP去除效果最好,去除率为67.7%,TP浓度由6.5 mg/L可降至2.1 mg/L;各试验组中DO的浓度均大于2 mg/L。

The test studied the improvement effect of composite microbial agents with different ratios attached to the carrier on the water quality of the black and odorous water bodies.The results showed that the 3#test group has the strongest removal ability to remove COD,which can reduce the COD concentration from 1992 mg/L to 637 mg/L,the removal rate reaches 68.1%.The strongest removal capacity for ammonia nitrogen is 1#bacteria,and its ammonia nitrogen concentration may be reduced from 215 mg/L to 38 mg/L,and the removal rate is up to 82.4%.The TP removal effect is the best,the removal rate is 67.7%,and the TP concentration can be reduced from 6.5mg/L to 2.1 mg/L.The concentration of the DO in each test group is greater than 2 mg/L.
