[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse. This process is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Wastewater treatment mainly includes physical treatment, chemical treatment, and biological treatment.

[0003] In order to meet the sewage treatment effect, current sewage treatment equipment will often filter the sewage in advance through a filtering device, thereby reducing the pressure of subsequent treatment.

[0004] However, the filtering device in the prior art mainly filters sewage through a flat filter net, so that impurities filtered out of the sewage will block the filtering channel, thereby affecting the subsequent filtering effect. In view of this, we propose a new sewage filtering device. Utility Model Content
