中文摘要：

磷酸盐工业废水经磷酸铵镁沉淀法处理后，出水的TP为10．26mg／L、TN为67．32mg／L、电导率为30000μS／cm。探讨了采用SBR法对其进一步处理的可行性。采用常规的活性污泥，通过逐步提高废水的含盐量，驯化出了在较高含盐量下仍具有较好活性的活性污泥。考察了含盐量和运行周期对去除TN、TP、COD的影响。结果表明，当沉淀出水和生活污水以1：1混合后，TN、TP、COD分别约为50、7、320mg／L，电导率约为15000μS／cm；在运行周期为10h（厌氧：1．5h、好氧：4．5h、缺氧：2．5h、后好氧：0．5h、沉淀排水和闲置：1．0h）的条件下，出水TN〈15mg／L、TP〈1．0mg／L、COD约为22mg／L，对TN、TP、COD的去除率分别可达75％、86％、92％以上。

英文摘要：

After phosphate-containing industrial wastewater is treated by magnesium ammonium phosphate （MAP） process, the effluent TP, TN and conductivity are 10.26 mg/L, 67.32 mg/L and 30 000 μS/cm respectively. The feasibility of the treatment of the effluent by SBR process is discussed. Common activated sludge is domesticated by increasing wastewater salinity. The domesticated sludge has good activity at high salinity. The effects of salinity and operation period on removal rates of TN, TP and COD were investigated. The results show that when the sedimentation effluent and sewage are mixed at a ratio of 1 ： 1, TN, TP, COD and conductivity are 50 mg/L, 7 mg/L, 320 mg/L and 15 000 μS/cm respeetively. When the operation period is 10 h （anaerobie time of 1.5 h, aerobic time of 4.5 h, anoxie time of 2.5 h, post-aerobic time of 0.5 h, sedimentation, drainage and idle time of 1.0 h）, the effluent TN, TP and COD are less than 15mg/L, 1.0 mg/L and about 22 mg/L, the removal rates being above 75%, 86% and 92% respectively.
