Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, and more specifically, particularly relates to a sewage treatment device. Background Art

[0002] Municipal sewage usually refers to the discharged water from life and production that is polluted to a certain extent. The sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants in sewage include pathogen pollutants, oxygen-depleting pollutants, plant nutrients and toxic pollutants. In municipal management projects, municipal sewage treatment plants are usually required to treat municipal sewage. However, the current sewage treatment plants have poor filtering effects, resulting in incomplete sewage filtration, which affects the surrounding environment. In addition, the debris in the sewage can easily cause the filter to be blocked, which in turn affects sewage treatment and discharge. Utility Model Content
