富阳污水处理厂四期工程设计方案

Design Scheme of Fuyang Wastewater Treatment Plant Phase Ⅳ Project

为满足日益增长的污水量和《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准的排放要求,富阳污水处理厂实施四期扩建及升级改造工程,四期工程采用多模式倒置AAO工艺,在充分利用原有一、二、三期处理设施基础上,对现状进行改造,同时新增深度处理构筑物进行提标改造。该文介绍了污水厂扩建及提标改造中的污水,污泥处理工艺和主要处理构筑物的设计参数。

In order to meet the increasing sewage flow and the discharge requirement of Grade Ⅰ A standard in Pollution Discharge Standard of Municipal Wastewater Treatment Plant(GB 18918-2002),the Phase-Ⅳ extension and upgrading reconstruction project is implemented for Fuyang Wastewater Treatment Plant.The multi-mode inverted AAO technology is used for the Phase Ⅳ Project.On the basis of fully utilizing the treatment facilities of Phase Ⅰ,Phase Ⅱ and Phase Ⅲ,the present situation is reconstructed,at the same time,the advanced treatment structures are added for the upgrading reconstruction.The article introduces the sewage in the extension and upgrading reconstruction of wastewater treatment plant,and the design parameters of sludge treatment technology and the main treatment structures.
