Buried efficient initial rainwater treatment device

Abstract

The invention provides a buried efficient initial rainwater treatment device. The buried efficient initial rainwater treatment device comprises a water inlet bin and a treatment bin. A pushing assembly is arranged on one side of the water inlet bin, and the bottom of the water inlet bin is communicated with the treatment bin through a poor water guide pipe. One side of the poor water guide pipe is communicated with a good water guide pipe, and the other side is communicated with the bottom of the treatment bin through a circulating pipe. The bottom of the treatment bin is communicated with a blow-off pipe, and one side of the treatment bin is communicated with a green belt through a transparent discharge pipe. The quality of filtered rainwater is detected through a turbidimeter. If the rainwater meets the standard, the rainwater is conveyed into a purification tank through an eduction pipe and purified through a purification filler, is disinfected through an ultraviolet lamp and then is discharged. If the rainwater does not meet the standard, the rainwater is conveyed into a filter tank again through the circulating pipe, a movable filter plate is pushed to ascend and descend through a first pneumatic cylinder, the staggered aperture of the filter holes of a movable filter plate and the fixed filter plate is changed, so that the filtering effect is adjusted, and fine treatment of the rainwater is ensured.

Description

technical field [0001] The invention relates to an underground high-efficiency primary rainwater treatment device, which belongs to the technical field of rainwater treatment. Background technique [0002] In recent years, the problem of environmental pollution in my country has been very serious. Phenomena such as foul-smelling water bodies and smog are quite common. There are two kinds of rain and sewage drainage systems, the diversion system, among which the combined drainage system occupies a dominant position. The phenomenon of wrong connection and random connection of urban rain and sewage pipe networks is common. The factory was forced to close the sewage pipe network, causing a large amount of initial rainwater and sewage to flow out, causing serious environmental pollution; some developed cities spent a lot of manpower and material resources on rainwater and sewage diversion reconstruction projects, and the diverted rainwater was directly discharged into natural water...

[0002] In recent years, the problem of environmental pollution in my country has been very serious. Phenomena such as foul-smelling water bodies and smog are quite common. There are two kinds of rain and sewage drainage systems, the diversion system, among which the combined drainage system occupies a dominant position. The phenomenon of wrong connection and random connection of urban rain and sewage pipe networks is common. The factory was forced to close the sewage pipe network, causing a large amount of initial rainwater and sewage to flow out, causing serious environmental pollution; some developed cities spent a lot of manpower and material resources on rainwater and sewage diversion reconstruction projects, and the diverted rainwater was directly discharged into natural water bodies. The incoming sewage has been well controlled, but the water environment pollution has not been improved, but ha
