Sewage treatment equipment and sewage treatment method thereof

Abstract

The invention discloses sewage treatment equipment. The equipment comprises a box body, a water outlet is communicated with a water outlet pipe, discharge baffles are evenly installed on a discharge lifting belt at intervals, one side of the discharge lifting belt is provided with a solid waste discharge port, and a solid waste collection box is fixedly installed at the bottom of the solid waste discharge port; rotating fan blades are movably installed at the water outlet, a blanking impeller is located in a flocculant placement chamber, the bottom of the flocculant placement chamber is communicated with the interior of the box body, a wheel shaft of a second driven synchronous pulley is fixedly connected with an air blowing wheel of an air blower, and an air outlet end of the air blower is communicated with an aeration plate through a pipeline. The sewage treatment equipment fully converts potential energy of sewage falling into kinetic energy, through kinetic energy conversion, sewage can be subjected to aeration treatment while a flocculant is added to the sewage, a motor is not needed for driving, solid waste in the domestic sewage can also be blocked and filtered, the situation that the solid waste blocks the equipment and the filtering effect is influenced is prevented, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of domestic sewage purification, in particular to sewage treatment equipment and a sewage treatment method thereof. Background technique [0002] An aeration device for sewage treatment with the application number "CN201711303771.8" in the prior art includes a machine base, the lower end of the machine base is welded with a plurality of supports distributed in a ring shape, and the top of the machine base is set There is a case, a turntable is provided between the case and the machine base, the turntable is connected to the machine base and the case in rotation, and a stirring rod is slidably connected to the turntable, and a stirring blade is welded at the lower end of the stirring rod. The upper end of the case is fixedly connected with a motor, the output shaft of the motor is fixedly connected with a drive pulley, the end of the case away from the motor is fixedly connected with a shaft seat, and a suppo...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned aeration device for sewage treatment still has obvious defects during use: 1. The above-mentioned device is driven by a motor, and the long-term operation of the motor is likely to cause damage or malfunction, thereby affecting the aeration effect; 2. The above-mentioned device is only It can aerate the sewage, and can not add the corresponding flocculant according to the sewage discharge, and the function is relatively simple; 3. The above-mentioned device cannot filter the solid matter in the sewage, and the solid matter is easy to block the nozzle and affect the normal operation of the sewage pool aeration
