Abstract:

Based on years of wastewater treatment plant operation and management experience and the later operation management and takeover，combined with the preliminary design，specific suggestions and ideas were given in the construction drawing design stage. These included as follow：installing a separate electricity meter on the distribution cabinet of high-power equipment facilitates to monitor the electricity consumption of key equipment during operation and conducting energy-saving analysis，increasing the connection pipe between the accident pool and the drainage pipe of the regulating pool and adding the overflow pipe of the regulating pool to save electricity consumption，adding a half tank vent pipe below the filler plate of the hydrolysis acidification tank to facilitate maintenance work and reduce operational impact，adjusting the hand valve of the aerobic section of the biochemical tank into an electric valve to improve the regulation space for nitrogen and phosphorus removal in the biochemical system，and changing the dosing form for observation and regulation. By optimizing and adjusting the design scheme before construction，some issues that affect later operation could be avoided，while reducing the transformation cost after operation，effectively ensuring the orderly operation management and efficiency improving the operation management work after takeover，and also providing experience reference for the early design of similar sewage treatment plants.

Key words: wastewater treatment plant, preliminary design, construction drawing design, design optimization, operation management

摘要：

基于多年污水处理厂运行管理经验及后期接管运营的需求，并结合初步设计，在施工图设计阶段对前期未考虑周全的运行操作习惯、调控管理细节等方面提出问题并给予针对性的建议和思路。如在大功率设备配电柜上单独安装电表，方便运营中监控重点设备用电情况及开展节电分析；事故池增加与调节池排水管的连通管、增设调节池超越管，利于节约电耗；水解酸化池填料板以下增设半池放空管，方便检修工作开展及降低运行影响；生化池好氧段气管手动阀分段调整成电动阀，以提升生化系统脱氮除磷的调控空间；加药形式改成池面加药，有利于观察调节加药量等。通过在施工前的设计方案优化调整，可规避一些影响后期运行的问题，同时可降低运营后的改造费用投入，有效保障接管后的运营管理工作有序开展及效率提升，也可为同类型污水处理厂的前期设计提供经验参考。
