摘要

各种应用的水质标准和生物干燥剩余污泥对资源回收的命运有很大影响。这些标准必须切实可行,同时确保公共和环境健康、安全和经济效益。本研究以北京某中水处理厂为研究对象,研究了中水利用装置和生物干燥污泥处理装置。本研究阐明了不同用途的再生水水质标准和生物干燥剩余污泥标准。值得注意的是,再生水在经济效益方面具有巨大的市场需求。然而,由于较高的操作成本和较低的TP含量,生物干燥过剩面临挑战。污水处理厂出水水源的热能不仅可以用于生物干燥过程鼓风机,还可以提高空气温度以加速生物干燥过程。

Comparison of economic benefits for the utilization of reclaimed resources from wastewater treatment plants: a case study in Beijing
Abstract The fate of resource recovery is significantly influenced by the standards of water quality and bio-dried excess sludge for various applications. These standards must be practically attainable while ensuring public and environmental health, safety, and economic advantages. The present study investigates a reclaimed wastewater treatment plant (WWTP) in Beijing that incorporates both reclaimed water utilization facility and bio-dried excess sludge treatment. The study elucidates the standards for reclaimed water quality and bio-dried excess sludge for diverse applications. Notably, reclaimed water demonstrates substantial market demand in terms of economic benefits. However, bio-dried excess faces challenges due to higher operational costs and lower TP content. The heat power of the WWTP effluent water source can not only be harnessed for the bio-drying process blowers but also be elevated air temperatures to expedite the bio-drying process.
