摘　　要：对有效微生物群(EM)进行复壮试验,并用复壮的EM活性液在厌氧条件下对奶牛场废水进行处理.试验结果表明:用糖蜜以及糖蜜与高浓度奶牛场废水混合物均能有效复壮EM;EM活性液能有效降解奶牛场废水的CODMn.与不添加EM活性液的对照组相比,添加EM活性液可以使CODMn降解比较迅速.添加0.1%EM活性液对奶牛场废水的去除效果要好于添加0.05%的EM活性液.试验还表明,EM活性液对奶牛场废水臭味去除效果非常明显.Laboratory experiments were conducted on EM rejuvenation and the application of rejuvenated EM activated liquid to treatment of dairy effluent under anaerobic condition. Experimental results show that molasses and its mixture with high-concentrated organic effluent from dairies are beneficial for EM rejuvenation, and that EM activated liquid added to dairy effluent can effectively decrease CODM, by improving the microorganism activity. It is also indicated that the effect of dairy effluent treatment with EM activated liquid of 0.1% added is better than that with EM activated liquid of 0.05 % added, and that the EM activated liquid can effectively remove the offensive odor from dairy effluent.
