Study on Restoration Characteristics of Lake by Artificial Compound Bacteria
Adding compound bacteria groups to lake in which photosyntheric 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.
