[0007] Furthermore, the capture net assembly includes a mounting frame and a filter net, the mounting frame is a rectangular frame structure, and the filter net is detachably installed at the bottom of the mounting frame; a accommodating space for accommodating suspended matter and colloidal substances in the wastewater is formed inside the mounting frame, and an impurity outlet is opened on the left side wall of the mounting frame, and the impurity outlet is connected to the accommodating space.

[0008] Furthermore, the inner surface of the left side wall of the mounting frame is designed to be arc-shaped to form a flow guide structure, and the impurity outlet is located in the middle of the arc.

[0009] Furthermore, a plurality of arc-shaped connecting parts are arranged on the mounting frame, and a hook part is arranged at the end of the twisted rope, and the hook part is hung on the arc-shaped connecting part.

[0012] Compared with the prior art, the utility model has the following advantages or technical effects:

[0013] The capture net assembly is controlled to rise and fall by multiple winches to capture impurities such as suspended matter and colloids in the wastewater, thereby reducing the COD of the wastewater. When capturing impurities, the two sets of reciprocating winding and pulling mechanisms operate synchronously to ensure that both ends of the capture net assembly rise at the same time, so that the suspended matter and colloids on the pool surface can be captured cleanly. The left reciprocating winding and pulling mechanism is closed, and the motor of the right reciprocating winding and pulling mechanism is started. The right end of the capture net assembly is raised, and the impurities in the mounting frame can be discharged through the impurity outlet.
