摘要
介绍了采用气浮+UASB+生物接触氧化法处理乳场废水、乳品接收站废水和乳品加工厂废水混合水改造工程。运行结果表明:进水CODCr浓度在3000 mg/L左右时,最终出水水质均能达到《水污染物排放限值》(DB44/26-2001)中的第二时段二级标准。
The system of dissolved air flotation+UASB+biological contact oxidation process was introduced for the treatment of milking dairy wastewater.The results proved that when the COD concentration of the inflow was reduced from about 3000 mg/L,the quality of wastewater treated by waste disposal plant could be in line with the designed standards.
