Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to an impurity screening device for wastewater filtration. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify it, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. Domestic sewage refers to the wastewater discharged by people in their daily life activities. This wastewater is mainly polluted by domestic waste and human excrement. The quantity, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the reproduction of microorganisms and contains a large number of bacteria and pathogens. From a health point of view, it has certain hazards.

[0003] The existing patent (publication number: CN219783991U) discloses a wastewater filtering and screening device, including a screening box, one side of the screening box is opened, and a wastewater feeding assembly is arranged on the screening box. A transverse fixing rod is fixedly installed on the inner wall of one side of the screening box, and filter screen plates are rotatably installed on both sides of the transverse fixing rod. The two filter screen plates are arranged at an angle. The wastewater filtering and screening device allows wastewater to be screened and filtered to enter through the wastewater inlet on the wastewater feeding assembly, and the wastewater after entering will flow out from two dispersed outlets and fall on the two filter screen plates. The filter screen plates are placed in an inclined state, and the fallen wastewater will fall from the filter mesh holes in the filter screen plates, and impurities and particulate matter in the wastewater will be blocked and filtered. Because the filter screen plates are arranged at an angle, under the action of gravity and the flushing of wastewater, the impurities and particulate matter can be flushed into the collection leak frame on the impurity collection assembly, and the wastewater falls into the wastewater collection box at the bottom.

[0004] During the use of the above-mentioned document, it is difficult to evenly remove impurities on the filter screen plate by relying solely on gravity and flushing of wastewater. At the same time, when the impurities in the collection drain frame increase, it will cause blockage and wastewater will overflow. It needs to be cleaned manually, which is inconvenient to use.
