Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filtration and stirring device for a wastewater treatment tank. Background Technology

[0002] Wastewater treatment can be classified according to its source into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater refers to the wastewater generated in daily life. When filtering and stirring some industrial wastewater, because this type of wastewater contains a lot of chemical pollutants, it is necessary to use agents to chemically react and treat this type of wastewater. Therefore, a filtration and stirring device is needed to treat this type of industrial wastewater containing a lot of chemical pollutants.

[0003] CN209338274U discloses a filtration and stirring device for a sewage treatment tank, including a treatment tank body. An inlet is provided on the top of the treatment tank body, and an outlet is provided on one side of the treatment tank body. Support legs are provided at the four corners of the bottom of the treatment tank body. A base is provided at the end of the support leg away from the treatment tank body. A motor is provided on the top of the treatment tank body. A motor shaft is provided at one end of the motor. The end of the motor shaft near the motor is rotatably connected to a third bearing located at the center of the top of the treatment tank body.

[0004] In traditional wastewater treatment ponds, wastewater enters through the inlet and flows out through the outlet during the mixing and filtration process. The reaction speed between the wastewater and the chemicals is accelerated by mixing alone, resulting in a very short actual mixing time. This leads to insufficient reaction time and affects the mixing acceleration effect, resulting in poor neutralization of the chemicals and inadequate wastewater treatment. Consequently, the wastewater will still pollute the environment after discharge. Furthermore, the chemicals are replenished only once and are easily carried away by the water flow, resulting in low utilization and wasted resources. Therefore, we propose a filtration and mixing device for wastewater treatment ponds. Utility Model Content
