Problems solved by technology

[0003] At present, in the process of sewage filtration, the large particles of impurities in the sewage are generally filtered through the filter screen, and then filtered from the filter plate by using the gravity of the sewage. Impurities are large particles that easily block the mesh and affect the filtration efficiency. At the same time, the lift pump used for water delivery in the process of sewage treatment consumes a lot of power, which is not energy-saving enough. There is a phenomenon of the lift pump idling, which affects the life of the lift pump.

Abstract

The present invention discloses layered sewage treatment equipment which comprises a pretreatment box, a purification box, a water storage tank, a lifting pump box, an isolation screen plate, a first motor, a knife rest, a dragon shaft, a spiral conveying blade, a water pressure sensor, an impeller, a second motor, a lifting pipe, a filter box, a controller, a base, an ozone generator and an arc-shaped scraper. The arc-shaped scraper is matched with the torsion spring so that the scraper head of the arc-shaped scraper can extend into meshes of the isolation screen plate, compared with a traditional scraper, the impurity scraping effect is improved, meanwhile, the loss of the arc-shaped scraper is reduced, and energy conservation and environmental protection are achieved by adopting a timed opening scraping mode; and the controller receives a water pressure signal of the water pressure sensor to adjust starting, stopping and the rotating speed of the second motor, the phenomenon that the motor is damaged due to idling is avoided, meanwhile, a good energy-saving effect is achieved, the sewage filtering efficiency is improved through the bottom-to-top filtering mode of sewage in the filtering box, meanwhile, sludge discharging is facilitated, design is reasonable, and the management cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a layered sewage treatment equipment. Background technique [0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and the sewage will also enter the human body and affect human health. [0003] At present, in the process of sewage filtration, the large particles of impurities in the sewage are generally filtered through the filter screen, and then filtered from the filter plate by using the gravity of the sewage. Impurities are large particles that easily block the mesh and affect the filtration efficiency. At the same ...
