A water pollution control system will cost a great deal of money, so it looks very important to view form the angle of area coverage and to plan the system scientifically, economically and reasonably. We can go through the way of the optimal distribution of pollutant elimination to establish the dislodging rate of the pollution source of each sewage treatment plant in order to reach the economic and reasonal goal required by the overall situation of the area. In this paper the cost function of the secondary sewage treatment plant was established by the series design method and the cost function itself and other effectual factors, the various parameters were also discussed and analyzed. Then suppose there are several major pollution source outlets to discharge sewage. According to the environmental standard of the water or the water demand, we can derive the elimination amount and elimination rate of major pollutant such as BOD_5 of this area, by means of calculating the water selfpurifying ability. The goal is to get the minimum cost of the full elimination amount, so we can optimally distribute the amount to several pollution sources of this area in order to establish the dislodging rate of the pollutants of each pollution source. In this paper, two mathematical models are put forward for discussion : Mathematical Model of Extreme Value of Conditions and Matrix Mathematical Model.
