Effects of Different EM Solution Addition Ratios and Incubation Methods on Dairy Effluents Treatment

In view of heavy pollution caused by dairy effluent, researches on impact of EM activated solution incubation methods, EM addition on dairy effluents treatment are conducted in the labs. Results obtained show that (1) EM addition to dairy effluents can decrease COD and available phosphorus by improve the microorganism activity. (2) Rejuvenated EM solution exhibit biological flocculation characteristics through increasing the amount of sludge sedimentation. (3) Rejuvenated EM solution to dairy effluents anerobically could sufficiently reduced the offensive odour. (4) There is little distinction among effects of different treatments with EM addition ratios and incubation methods on pollutant removal in dairy effluent.
