摘要
采用水解-生物接触氧化法处理医院污水。污水处理站设计处理规模800 m3/d,水解池、生物接触氧化池停留时间分别为3.6、8 h。处理站进水CODCr、NH3-N、TP浓度平均值分别为103、11.6、1.4 mg/L,处理后出水CODCr、NH3-N、TP平均浓度为24.6、0.35、0.37 mg/L,优于广东省《水污染物排放限值》一级排放标准。项目总投资92万元,污水处理成本约为0.46元/m3。运行实践表明:该工艺处理效果稳定、耐冲击、占地少、维护简单,是一种处理医院污水经济可行的方法。
Hydrolysis-biological-contact-oxidation method is used to treat hospital sewage.The design capacity of wastewater treatment station is 800 m^3/d.The hydraulic retention time of the hydrolytic acidification stage and biological contacting oxidation reactor are 3.6 and 8 h,respectively.The initial CODCr,NH3-N and TP concentrations are 103,11.6 and 1.4 mg/L,and the mean values of effluent are 24.6,0.35 and 0.37 mg/L,superior to the first grade of water pollutant discharge limits of Guangdong province.The construction investment of wastewater treatment plant is 0.92 million yuan and running cost is 0.46 yuan/m^3.The running practice indicates that the technique is stable,less land occupied and the daily running and maintenance is proper.It is an economical and feasible method for the treatment of hospital sewage.
