Test on EM Bacteria Applied in Treating Landscape Water

Abstract

Taking domestic sewage as the research object, through adding different amount of EM bacteria culture medium to the sewage and EM rejuvenation bacteria which cultivated by combining immobilization technology, wastewater treatment mechanism of EM bacteria was explored, and the treatment effect of COD, ammonia nitrogen and total phophorus was observed as well as the best collecting volume. The results showed that EM rejuvenation bacteria is better than pure EM culture medium on the removal rate of ammonia nitrogen, total phosphorus and COD in wastewater, furthermore removal efficiency by 35 mesh rejuvenation bacteria is higher than 120 mesh.
