Abstract:
The Three?year Action Plan for Improving the Quality and Efficiency of Urban Sewage Treatment (2019-2021) proposes to accelerate the improvement of urban sewage collection and treatment facilities, and formulate a systematic “one plant one policy” plan for sewage treatment plants with influent BOD5 concentration less than 100 mg/L. A simple calculation method of water quality and quantity balance is adopted to quickly evaluate the contribution rate of different types of water quantity and quality to the influent concentration of sewage treatment plant, by inputting the measured data and combining with the theoretical data, which could provide data support for the formulation of later engineering scheme.
