摘要
六圩污水处理厂二期工程属于国家"三河三湖"中淮河流域水污染防治规划工程,采用了改良型A2/O工艺。在调试运行中,进水水质波动较大,多次出现进水TN浓度异常升高现象,经试验,最终采取了投加碳源的措施,保证了出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,对保护长江水质起到了积极作用。
Second-phase project of Liuwei WWTP is a water pollution control planning project of Huaihe watershed in the national "Three Rivers and Three Lakes" project. The project uses a modified A2/O process. The influent quality fluctuated during the commissioning period and TN concentration was abnormally high several times. Through the experiment, the measure of dosing external carbon source was determined to be used to ensure the effluent to meet the first level A criteria specified in Discharge Stand- ard of Pollutants for Municipal Wastewater Treatment Plant ( GB 18918 - 2002 ), which plays a positive role in the Yangtze River water protection.
