According to the data in the table, it can be calculated that from 2005 to 20 1 1 year, the electricity consumption of urban sewage treatment in China accounted for 2% of the domestic electricity consumption (pictured), and it has been on the rise in recent years.
Sewage treatment processes are different, ranging from 0. 1 yuan to 1.5 yuan for high-membrane bioreactors and low-artificial oxidation ponds. CCQ process is the lowest energy consumption per ton of water at present. Chongqing technology of CCQ process is the technology with the lowest power consumption per ton at present, with sewage flowing by itself of 0.0248 ~ 0.0744 kW h h and sewage lifting type of 0.1128 ~ 0.1624 kW h?
CCQ process Chongqing technology, without mixed liquid reflux pump, sludge reflux pump, sludge lift pump and sludge filter press, the power consumption of the built urban sewage treatment plant is only 1 low-pressure lift pump (except gravity flow), 1 low-pressure lift circulating pump operation 1 ~ 6 hours, 1 low-pressure low-power fan operation/.
