detailed description

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Example:

An underwater pollutant adsorption and filtering device, comprising a sewage pipe 1, the sewage pipe 1 is connected to a steering pipe 2, a sewage pool 3 is arranged below the steering pipe 2, the sewage pool 3 is connected to a regulating pool 4 through a water pump, and the regulating pool 4 is connected to a mixing pool The coagulant adding tank 5 is connected, and the adjustment tank 4 is provided with a stirring blade 401. The adjustment tank 4 is connected to the MBR pool 6 through a water pump, and the mud outlet of the MBR pool 6 is connected to the sludge storage tank 8 through the dredger 7. The MBR The water outlet end of the pool 6 is connected with the clear water pool 10 through a water pump.

The steering pipe 2 is a hollow cavity with an opening at one end. The top of the steering pipe 2 is provided with a water inlet end of the steering pipe connected to the sewage pipe 1. The bottom of the steering pipe 2 is provided with a water outlet end of the steering pipe. The inside of the steering pipe 2 is provided with a filter plate. 11. The filter plate 11 is located between the water inlet end of the steering pipe and the water outlet end of the steering pipe.
