How much electricity does the sewage treatment plant consume for one kilometer?

This question is too general. It depends on the quality of wastewater, such as cod ranging from several hundred to tens of thousands, and its biodegradability is different. What kind of water is this? The power consumption of 1 water varies from a few cents to several yuan, and the treatment cost ranges from 1 yuan to more than 20 yuan. Need to provide specific water sources and water quality. For domestic sewage, the influent COD is 400. If it meets the first-class discharge standard, and if the contact oxidation method is adopted, the comprehensive power consumption per ton of water is below 0.5kwh, which is also related to the selection of process.
