高排放标准下的改良AAO+深度处理工程案例

Project Case of Modified AAO and Advanced Treatment Process under High Emission Standards

针对台州地区对污水处理厂出水标准提高的要求,建设了台州市水处理发展有限公司污水处理厂三期工程,工程规模为10×10^4m^3/d。针对进水以生活污水为主,含有部分工业废水的特点,污水处理采用技术可靠、抗冲击负荷能力强且具有生物脱氮除磷功能的改良AAO工艺,工艺流程为改良AAO+高效沉淀+深床滤池+臭氧接触工艺。项目于2018年竣工并投产运行,实际运行表明,出水水质稳定达到《台州市城镇污水处理厂出水指标及标准限值表(试行)》的要求。

In response to the requirements of Taizhou to raise the effluent standard of sewage treatment plants,the third phase of sewage treatment plant of Taizhou Water Treatment Development Co.,Ltd. was constructed. The project scale was 100 000 m^3/d. In view of the characteristics of domestic sewage as the main influent and also containing some industrial wastewater,the sewage treatment adopts modified AAO with reliable technology, strong shock load resistance and biological nitrogen and phosphorus removal functions. The overall process is modified AAO + high-efficient sedimentation tank + deep-bed filter + ozone contact technology. The project was completed and put into operation in2018. Actual operation results showed that the effluent quality stably met the requirements of Taizhou Municipal Wastewater Treatment Plant Effluent Index and Standard Limit Table( Trial).
