摘要
浙江省于2018年出台了《关于推进城镇污水处理厂清洁排放标准技术改造的指导意见》,启动了100座城镇污水处理厂的清洁排放技术改造工程,对城镇污水处理厂出水进一步提标。从清洁排放技术改造工程的实践出发,针对城镇污水处理厂在前期调研、方案设计过程中遇到的误区和问题,包括设计流量和水质的确定、工业废水对提标的影响、生物池改造对运行稳定性的影响等方面重点进行了分析和探讨。同时,结合工程实践,从加强城镇污水处理厂的稳定运行保障和消除日常运行的薄弱环节出发,分别从纳管污水控制和内部设计优化2个方面,针对性地提出了城镇污水处理厂清洁排放技术改造的具体对策和建议,以供其他城镇污水处理厂改造时参考。
In 2018, Zhejiang Province issued The Guidance on Promoting the Clean Emission Standard Technology Transformation of Urban Sewage Treatment Plants,and launched the clean emission technology transformation of 100 urban sewage treatment plants,further upgrading and reconstruction for urban sewage treatment plants. Based on the practice of clean emission technology transformation project,this paper analyzed the errors and problems of some urban sewage treatment plants in the process of preliminary investigation and renovation scheme design,including the determination of design flow and water quality,the influence of industrial wastewater on the improvement of standards,the influence of reconstruction of activated sludge process on operational stability,etc. At the same time,combining with engineering practice and based on strengthening the stable operation of urban sewage treatment plant and eliminating the weak links in daily operation,this article put forword countermeasures and suggestions which could be used as a reference for the renovation of other urban sewage treatment plants on clean emission technology transformation of urban sewage treatment plant,from the aspects of the control of sewage collection and the optimization of internal design.
