Parameters such as main pollution source types, discharge time periods, discharge amount and the like around the target water body are obtained through field sampling and monitoring and input into the microcomputer embedded control system 19. The feeding storage bin 4A is integrally higher than the water inlet storage bin 4B and is a place for placing pollutant particles or stock solution. Water enters the water inlet storage bin 4B from the water outlet 3 through the water pump 2, the microcomputer embedded control system 19 controls the feed gate 6A to be opened according to the parameters input in advance, particles with the target amount or stock solution with the target volume are released to enter the water inlet storage bin 4B, and then the feed gate 6A is closed. When the water level of the water inlet storage bin 4B is reduced to a certain degree, the water level monitor 5 transmits a water level signal to the microcomputer embedded control system 19, and the microcomputer embedded control system 19 controls the solution outlet gate 6B to be closed and controls the material inlet gate 6A to be opened according to the water level signal so as to supplement particles or stock solution. The first agitator 8A is in a long-time open state for the purpose of sufficiently mixing particles or a stock solution with water to simulate generation of sewage and to attain a target concentration. Because the interaction of a plurality of pollutants is often realized in the actual situation, the device can be provided with a plurality of feeding storage bins 4A and water inlet storage bins 4B (four groups are arranged in the embodiment, the structures of the four groups are completely consistent), a plurality of kinds of sewage enter the homogenizing bin 7 according to different proportions according to the actual situation, and the microcomputer embedded control system 19 controls the second stirrer 8B to be started so as to achieve the purpose of homogenizing and mixing the sewage.
