As a kind of coagulant, polyferric silicate is used to compare the remo val effects on COD, nitrogen, and phosphorus in feeding coagulant into biologica l reactor directly(feeding coagulant activated sludge process) with that of feeding coagulant into the bioreactor effluent(post-coagulating pro cess). Results indicate that the removal efficiency of COD and TN increases a little but there is no distinct dif ference between the two kinds of processes. The removal efficiency for TP of pos t-coagulating process is a little higher than that of feeding coagulant activate d sludge process, while the concentration of Fe ion in the former process, which also needs a series of equipment for coagulating and settling, is far stronger than that in latter process. So it is suitable for accessorial phosphorus remova l to feed coagulant into the bioreactor.
