UBF-砂滤工艺处理城市污水实验研究

Treatment of municipal wastewater by the process of UBF-sand filtration

采用UBF-砂滤工艺处理城市污水,成功地进行污泥颗粒化.在进水COD为150-600mg L,自然室温为26-30℃,水力停留时间为8h时,UBF-砂滤系统出水COD浓度小于60mg L,pH值接近7.

A new combined UBF-sand filter technology was uesed for the treatment of municipal wastewater. Microbial sludge granulation was succeeded in exam experiment.Under the condition of the primary COD concentration (150-600?mg/L), room temperature(26-30?℃) and the HRT (hydraulic retention time) 8?h, the COD concentration of the treated water was lower than 60?mg/L, the pH near 7.0. This research data could be used for the microbial-anaerobic treatment of the municipal wastewater.
