摘要
云南省某小城镇污水处理厂年久失修,污水处理能力大大降低,无法达到设计出水标准。根据污水处理厂进水水质和出水水质要求,结合污水处理厂原有污水处理设施,污水处理厂提标改造工程主体工艺方案为缺氧-好氧-接触氧化-解层式曝气塘-生态复合塘-快渗塘,处理出水达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准要求。
The sewage treatment capacity of the sewage treatment plant in a small town of Yunnan province decreased greatly cause of the equipments out of repair for long years, which leads to the effluent water quality not reach the design requirement. According to the influent and effluent water quality of the said plant with its initial sewage treatment facilities considered at the same time, the main process for the upgrading and reconstruction project of the said plant was determined as anoxia-aerobic-catalytic oxidation-layer type aerated pondcompound ecological pond-rapid infiltration pond. Using the said process to treat sewage, the effluent water of the said plant met the requirement of level A grade 1 in GB 18918--2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.
