摘要
通过外水排查和提质增效工程的实施可有效解决丘陵地区污水处理厂进水浓度低的问题。文章以深圳市鹅公岭水质净化厂为研究对象,研究了污水片区本底值和外水量,梳理了外水的进入路径和剥离方法。工程实施后,鹅公岭污水片区通过源头地块的雨污分流和正本清源、河道和暗涵总口整治、截流井改造等措施,总计剥离外水约0.96万m^(3)/d。旱季污水BOD浓度由76.21 mg/L提高至105.00 mg/L,雨季污水BOD浓度由61.34 mg/L提高至70.00 mg/L,污水系统的提质增效取得了显著效果。
The problem of low influent concentration in sewage treatment plants in hilly areas can be effectively solved through the implementation of external water investigation and quality improvement and efficiency enhancement projects.Taking the Shenzhen EGongling Water Quality Purification Plant as the research object,this paper studies the background value and external water volume of the sewage area,and sorts out the entry paths and stripping methods of external water.After the project implementation,through measures such as rainwater and sewage separation at the source plots,river and culvert main entrance regulation,and interception well renovation in the EGongling sewage area,a total of about 9600 m³/d of external water was stripped off.During the dry season,the BOD concentration of sewage increased from 76.21 mg/L to 105.00 mg/L,and during the rainy season,it increased from 61.34 mg/L to 70.00 mg/L.The quality improvement and efficiency enhancement of the sewage system have achieved remarkable results.
