曝气生物滤池在污水厂提标改造应用中的问题分析

Analysis of the Problems Existing in the Application of Aerated Biological Filterin the Upgrading and Renovation of Waste Water Treatment Plants

结合国内污水厂提标改造中曝气生物滤池的应用情况,从工程设计方面分析了滤池堵塞、出水有机物超标等问题。提出了对滤池表面水力负荷进行校核,采用加强预处理措施避免滤池堵塞,设置后置好氧单元消除有机物超标风险等设计建议。

Combining the application of aerated biofilters in the upgrading and renovation of domestic sewage treatment plants,this paper analyzes the design and application issues such as filter blockage and excessive organic matter in the effluent.It also proposes a method for verifying the design parameters of filter hydraulic load,adopting measures to strengthen pre-treatment to avoid filter blockage and setting up a post installed aerobic unit to eliminate the risk of excessive organic matter.
