Digest Of The Usage Of EM Biological Technology On Dealing With Organic Waste Water And Preventing Pollution On Animal Farms

The object of this essay is to discuss the uses of EM biowical technology on the aspect of protecting the environment. According to the characters of the micro- ecological systeml both complicated and stable, which is formed from the relationship of symbiosis and reproduction among EM biological groups, we choose the organic waste water and animals as the study abjects. They provide the best experimental terms. As a result of the experiments , COD in the organic waste water is decreased 20 percent to 40 percent more that it was in the past,and the decreasing percents of H2S and N2 on the animal farms are over 44 and 55 separately. The results prove that compared with physical or chemical manners, the advantages of using. EM biological techndgy on envionmental protection are as follows. First, it consumes less materials. Sencod, it needs only simple equipment. Third, no waste is produced duriny the whole procedure, which is good for improviny the envin-ment...
