提质增效背景下水质水量平衡简易测算与实践

Simple Calculation and Practice of Water Quality and Quantity Balance for Improving Quality and Efficiency

《城镇污水处理提质增效三年行动方案(2019—2021年)》提出加快补齐城镇污水收集和处理设施短板,针对进水BOD浓度不足100 mg/L的污水处理厂,制定“一厂一策”系统化整治方案。提出了污水处理提质增效水质水量平衡简易测算方法,通过输入污水处理厂实测数据,再结合理论数据,可快速评估不同类型水量及水质对污水处理厂进水浓度的贡献率,为后期工程方案的制定提供数据支撑。

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 BODconcentration 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.
