摘要
通过投加复合菌强化湖泊水体生物自净能力,并对其修复性能进行研究。结果表明:投加复合菌4d后出现修复效果,20d修复效果达到最佳状态,CODMn,TN,TP,Ch1-a都大幅下降;最佳投菌量为150mg/L,投菌周期为40d。
Adding compound bacteria groups to lake in which photosynthetic bacteria were the majority was suggested to intensify self-purification of water and the restoration characteristics were investigated. The experimental results showed that the restoration effect appeared 4 days later and got the best condition 20 days later. The concentration of CODMn, TN, TP and chlorophyll a decreased rapidly. The best inoculation amount was 150 mg/L and adding bacteria cycle was 40 days.
