Changes in total nitrogen (T.N.) and total phosphate (T.P.) content in environmental waste water upon the reaction of biological purifying reagents were measured and the reaction rate was evaluated. The purification capacity of two biological purifying reagents composed of vegetable Lactobacillus fermentum (V.L.F.), Saccharomyces cerevisiae( S.C), and Bacillus subtilis(B.S.) were evaluated and compared with that of commercial water purification system operating by local government. After 18days of reaction, the mixture of V.L.F. and S.C. showed dramatic decrease of T.N.(36.21% of the initial value). The mixture of V.L.F., S.C., and B.S. showed faster reaction rate to decrease T.P. compared with that of the mixture of V.L.F. and S.C. The reaction constant of mixture of V.L.F. and S.C. was estimated to be 0.178 day-1 by the curve fitting of the data of changes in T.N. during the reaction.
