城市污水处理厂升级改造问题分析

Problem Analysis of Upgrading and Reconstruction of Wastewater Treatment Plant

由于国家对污水处理厂出水水质指标提出更高的要求,为了满足新标准的要求,许多早期建造的污水处理厂正面临着升级改造。当前城市污水处理厂升级改造主要从工艺改造、设备改造和水力改造三方面进行,其中工艺改造是最常用的方法。因此,从污水处理工艺改造方面提出了升级改造技术措施和方法,并结合几个典型的升级改造工程实例进行阐述。

With the further stringent requirements for wastewater treatment plant effluent,many wastewater treatment plants are being upgraded and retrofitted in order to meet the new discharge standard. The technical reconstruction of the wastewater treatment plant was comprehensively summarized from the following 3 aspects： process reconstruction,hydraulic reconstruction and equipment reconstruction. The process reconstruction was the most common method.Combined with several successful cases,applicable measures and methods for upgrading reconstruction were discussed from the point of process reconstruction.
