厨余垃圾处理厂污水处理系统关键问题探讨

Discussion on Key Issues of Sewage Treatment System in Kitchen Waste Treatment Plant

厨余垃圾处理厂产生的污水具有污染物成分复杂,水质水量波动大,有机物和氨氮浓度高,含杂含油量大,处理难度大等特点。结合厨余垃圾处理厂污水水质特点,对污水处理系统中排放标准、预处理工艺和深度处理工艺的选择、生物池冷却系统以及碳源投加等关键问题进行了分析探讨。

The sewage produced by the kitchen waste treatment plant has the characteristics of complex pollutant composition,large fluctuations on water quality and quantity,high concentration of organic matter and ammonia nitrogen,large amount of impurities and oil content,and difficulty in treatment.Combined with the characteristics of sewage water quality of kitchen waste treatment plants,the key issues such as discharge standards,selection of pretreatment process and advanced treatment process,cooling system of the biological pool,and the addition of carbon sources in the sewage treatment system was analyzed.
