Automatic dredging type urban domestic sewage treatment system

Abstract

The invention discloses an automatic dredging type urban domestic sewage treatment system, and belongs to the technical field of domestic sewage treatment. The automatic dredging type urban domestic sewage treatment system comprises a pipeline and a filter box, a plurality of fan blades are fixedly connected to an adapter rod, and a transmission mechanism is connected to the adapter rod; a filter plate and a sliding rod are fixedly connected between a partition and the bottom of the inner cavity of the filter box, and the right end of the filter plate is connected with a dredging mechanism. According to the scheme, through cooperation of the transmission mechanism and the dredging mechanism, a dredging rod is driven to move back and forth to unblock the filter holes, the filter holes can be prevented from being blocked, a second rotating shaft is driven by the transmission mechanism to continuously rotate forwards and backwards, the scraping plates on the upper side and the lower side can be driven to move close to each other or away from each other in a reciprocating mode, garbage adhering to the outer wall of the filter plate can be cleaned, excessive accumulation is avoided, frequent replacement is avoided, garbage on the left side of the filter plate can be effectively collected by capturing a balloon, manual fishing is not needed, and the use effect of the filter box is improved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, and more specifically relates to an automatic dredging type urban domestic sewage treatment system. Background technique [0002] Urban domestic sewage is the wastewater discharged by residents in their daily life, mainly from residential buildings and public buildings in the city, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. [0003] Sewage treatment is the process of purifying s...

Problems solved by technology

[0004] At present, when treating urban domestic sewage, filter screens and filter plates are generally used to filter out the visible domestic garbage in the sewage. However, after a period of use, it is easy to cause the filter screen to be clogged, and the effective filtering treatment effect cannot be achieved. At the same time, there will be garbage attached to the outer wall of the filter screen that cannot be disposed of, resulting in the need to manually replace the filter screen frequently, which is not only time-consuming and laborious, but also has low efficiency in sewage treatment; and the garbage blocked by the filter screen cannot be effectively treated, which is not conducive to sewage processing
