水解酸化-接触氧化-BAF深度处理学生公寓污水

HYDROLYTIC ACIDIFICATION BIO-CONTACT OXIDATION AND BIOLGICAL AERATED FILTERS PROCESS FOR REUSING TREATMENT OF STUDENT HOSTEL SEWAGE

采用水解酸化-接触氧化-BAF组合工艺对广州市某中学学生公寓污水深度处理,处理后的水回用作景观湖水、绿化用水及冲厕水等。系统出水COD为16.3 mg/L,BOD5为5.03 mg/L,LAS质量浓度为0.35 mg/L,SS质量浓度为8.59 mg/L,氨氮质量浓度为0.38 mg/L,水质优于城市污水再生利用景观环境用水水质(GB/T 18921-2002)要求,且吨水处理成本为0.494元。该工艺具有处理效果好、运行费用低、占地面积少且操作简单等特点。

Student hostel sewage of an middle school in Guangzhou was analyzed, and it was disposed by hydrolytic acidification-biocontact oxidation and biological aerated filters process. Chemical oxygen demand（COD）, biological oxygen demand（BOD）, linear alklybezel sulfonates （LAS）, mixed liquor suspended solids（SS） and ammonia nitrogen in the effluent were about 16.3 mg/L, 5.03 mg/L, 0.35 mg/L, 8.59 mg/L and 0.38 rag/L, respectively. Reuse water can be used for landscape lake, irrigating greenbelt and flushing toilets, and the water quality can achieve the requirement of The reuse of urban recycling water-water quality standard for scenic environment use （GB/T 18921 --2002）. This process has many advantages, such as good processing effect, low operating cost, small space occupation and simple operation, etc.
