제목 Reverse Osmosis System을 이용한 축산폐수 처리 공정 개발
초록 The livestock waste affects largely an economical burden for the use of river and an eutrophication, because it has the very high load of nutritious salts. Also a single farming produces about 15.1 percent of pollutant sources and industrial stock farming is situated in the suburbs of city and in the sources of reserved water service. From the 1999, an applicable discharged water quality standards not only add COD and the number of E.coil but also enforce the concentration of total nitrogen (T-N) and total phosphorous (T-P) in livestock waste water. In according to the enforcement of regulation, the introduction of process for removing nitrogen and phosphorous is necessary.

Up to now, the livestock waste water treatment methods have depended on the biological treatment. Biological treatment needs large site and treatment degree varies according to the growth of microorganism. And its pre-treatment is complicated.

So we tried to find easy and economical process which could remove nitrogen and phosphorous. Reverse Osmosis System which we studied had a good rejection about T-N, T-P and the concentration of its permeate approximated an applicable discharged water quality standards. Furthermore it removed color of waste water.
