Anti-blocking sewage treatment device

Abstract

The invention provides an anti-blocking sewage treatment device which comprises a box body and a box cover, a feeding hopper is arranged on the box cover, and a first filtering structure, a second filtering structure and a third filtering structure are sequentially mounted in the box body from top to bottom; the first filtering structure is used for filtering large-particle impurities; the second filtering structure is used for filtering medium particle impurities, the second filtering structure comprises a second filtering plate, a cleaning mechanism is arranged below the second filtering plate, and the cleaning mechanism can clean filtering holes of the second filtering plate; the third filtering structure is used for filtering small-particle impurities, the third filtering structure comprises a third filtering plate, a first scraping plate is arranged above the third filtering plate, the first scraping plate is driven by a driving mechanism and abuts against the third filtering plate to slide, and the first scraping plate can conduct scraping and brushing cleaning on the third filtering plate; the multi-stage sewage treatment device is novel in structure, can perform multi-stage treatment on sewage, can clean filtering parts of small and medium particle impurities, effectively prevents the filtering parts from being blocked, and maintains a relatively good filtering effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an anti-clogging sewage treatment device. Background technique [0002] Sewage, usually refers to the polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. There are many types of sewage, and there are many technologies and processes to reduce the impact of sewage on the environment. Sewage treatment Most of the devices are filtered step by step through filter plates with different mesh numbers. Among them, large particles of impurities are easy to clean even if they are clogged, but it is not easy to clean up when the filter plates are blocked by small and medium particles, and powdery sludge is easy to cover the filter plates, causing large The silt in the range is not easy to clean, which affects the overall filtration. If it is disassembled and cleaned, the operation will be more troublesome....
