It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes, also known as sewage. It is water produced in a certain production and life process of human beings that has lost its use value or cannot be used. Wastewater discharged into the environment can cause water pollution, so its purification treatment is particularly important.

The present invention filters most of the granular impurities and colloidal impurities in the wastewater through the filter assembly to avoid affecting the subsequent treatment efficiency of the wastewater, and at the same time cleans the filter screen through the backwash assembly, and the impurities attached to it are separately exported, so that the staff does not need to dismantle the device to clean or replace the filter screen, which greatly improves the treatment efficiency of the wastewater.

[0004] The existing wastewater does not have good pretreatment before purification, especially when there are granular impurities and colloidal impurities in the wastewater, which will affect the subsequent treatment effect and quality of the wastewater. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Before the wastewater needs to be purified, it is first introduced into the treatment pool. At this time, most of the granular impurities and colloidal impurities in the wastewater are filtered through the filter net on the filter device to prevent these impurities from affecting the subsequent wastewater treatment efficiency. In addition, the design of the double-layer filter net not only improves the filtering effect of the device, but also cooperates with the motor on the stirring device to drive the connecting column, which in turn drives the stirring blades thereon to stir the wastewater in the treatment pool, so that the wastewater can better pass through the filter net, speeding up the filtration speed and effect. At the same time, when there are too many impurities on the filter net, the filter net can be pulled out of the treatment pool through the handle, which is convenient for the replacement and cleaning of the filter net.

[0014] 2. Install the mounting base on the fixing device at the lower end of the treatment pool. When the treatment pool needs to be moved, the hydraulic cylinder drives the piston rod at its output end to be pulled out of the positioning hole. At this time, the treatment pool can be lifted by the lifting ring, thereby facilitating the movement or installation of the treatment pool. BRIEF DESCRIPTION OF THE DRAWINGS
