The river water purification device has the characteristics of simple structure, convenience in manufacturing and installation, investment saving, low cost, low energy consumption and the like. However, the device mainly applies the physical principle to treat the water body, and is difficult to remove organic pollutants which can be dissolved in the water body, so that the problem of black and odorous water body is difficult to solve.

In the prior patent (patent application number: CN 108558059A), a device and a method for treating heavily polluted river water comprise a coagulating sedimentation tank, a mixing tank, a sewage pump, a sewage pipe, a coagulant adding and metering system and a solar and wind power generation system. The coagulating sedimentation tank is arranged on a river bank, is of a cuboid structure and is parallel to the river channel; the coagulating sedimentation tank is provided with a plurality of coagulating sedimentation tanks. The mixing tank sets up in coagulating sedimentation tank's shore one side, mixing tank and coagulating sedimentation tank intercommunication, and the play water of mixing tank flows into coagulating sedimentation tank. The sewage pump is arranged on the river bank and pumps and discharges sewage in the river into the mixing tank through the sewage pipe. The coagulant adding and metering system is arranged on the shore side of the mixing tank, and the coagulant added by the coagulant adding and metering system enters the mixing tank. The solar energy and wind energy power generation system is arranged on the river bank and is connected with the sewage pump through a cable. The method has the characteristics of low energy consumption, high efficiency and the like. However, the device treatment process mainly adopts a mode of combining physical chemistry, has good effect on removing inorganic pollutants and solid suspended matters, can not explain organic pollutants by biological treatment, and is difficult to solve the problem of black and odorous water body.
