研究了低温和常温条件下高硫酸盐负荷的间歇好氧污水处理系统的运行状况及其处理城市污水的效果。试验结果表明，两种系统的运行条件均为：曝气时间／停止时间＝20 s／2 min，COD／SO2－4＝0．75，COD浓度1500 mg／L；常温系统启动期为8d，低温系统启动期为12d。低温系统正常启动之后，和常温系统的COD去除效果相当，COD去除率也在75％以上。在运行过程中，系统中的硫酸根含量呈下降趋势，硫酸盐得到有效去除。

The process of intermittent aerobic wastewater treatment system with high sulfate was studied .The results shown that , the conditions of the system were:aeration time/halt time=20 s /2 min, COD/SO42-=0.75,COD concentration 1500 mg/L;The start time of normal temperature and low temperature system were 8 and 12 days, separately.The COD remove rate of the low temperature system was basically the same as the normal system , and the COD remove rate could reach 75%.The sulfate content in the system was declined with the process , then the sulfate was removed effectively .
