The effect of aeration combined with microorganisms in treating polluted lakes was studied under experimental conditions; then the aeration and microorganisms were integrated into a device to treat polluted lakes. The results show that aeration combined with microorganisms can increase the ability and efficiency of microorganisms to purify pollutants. Intermittent aeration is better than that of continuous aeration in treating polluted lakes, and the operating costs can be reduced using intermittent aeration. Under experimental conditions, the removal rate of COD, NH3-N and TP reached 55.55%, 79.52% and 61.54% respectively after 10 days. In the application study, the water quality was upgraded from Inferior Class V to Class III, and the removal rate of COD, NH3-N and TP reached 59.38%, 81.08% and 82.26% respectively after 3 weeks. The equipment has good application prospects in lake treatment. [ABSTRACT FROM AUTHOR] |
