Horizontal flow precipitation water collecting device

Abstract

The invention relates to a horizontal flow precipitation water collecting device, which comprises a device body and a water outlet ditch, wherein the device body is a cuboid structure, the water outlet ditch is arranged on the outer wall of the device body, a rectifying wall and a water collecting assembly are arranged in the device body, the water collecting assembly comprises a perforated watercollecting pipe, a water outlet pipe and a water outlet control gate, the perforated water collecting pipe is connected to one end of the water outlet pipe, the other end of the water outlet pipe extends into the water outlet ditch, the water outlet control gate is connected to the end, extending into the water outlet ditch, of the water outlet pipe through a pipeline, and a gap is formed in the connecting position of the pipeline and the water outlet pipe. Compared with the form of the water collecting groove, the device of the invention substantially reduces the water collecting area, so that the proportion of the effective precipitation area of the precipitation pond is large, and the load rate of the existing horizontal flow precipitation is obviously improved so as to improve the water production capacity of the system.

Description

technical field [0001] The invention relates to the technical field of advection mud-water sedimentation and separation in sewage treatment and water supply treatment, in particular to an advection sedimentation water collection device. Background technique [0002] In the treatment of sewage and water supply in the form of advection sedimentation, water collection tanks (triangular weirs, perforated tanks, etc.) are generally used to collect the clear water after mud-water separation. The water collection tanks are arranged on the water surface. In this form, sunlight will Algae breed in the sump, which is very troublesome to clean up, resulting in increased manual labor, and there are safety hazards in cleaning; the water collection section in the form of the original sump will cause a large change in the hydraulic flow state, not only the change in the hydraulic flow state of the water collection area, Its change will also extend to the front sedimentation section, result...

Problems solved by technology

[0002] In the treatment of sewage and water supply in the form of advection sedimentation, water collection tanks (triangular weirs, perforated tanks, etc.) are generally used to collect the clear water after mud-water separation. The water collection tanks are arranged on the water surface. In this form, sunlight will Algae breed in the sump, which is very troublesome to clean up, resulting in increased manual labor, and there are safety hazards in cleaning; the water collection section in the form of the original sump will cause a large change in the hydraulic flow state, not only the change in the hydraulic flow state of the water collection area, Its change will also extend to the front sedimentation section, resulting in a large reduction in the effective sedimentation area; moreover, the erection of the sump will affect the choice of the form of the scraper and suction dredger and the range of action; the sump is affected by many factors (settlement, deformation, Hanging foreign matter, etc.) will reduce the collection uniformity of the sump

[0003] The outlet weir is set behind the perforated wall in the water supply. Similarly, although the upper outlet water occupies a small space, the load on the weir is higher, and the change of the hydraulic flow state in the front section is greater than that of the sump, which is also unfavorable for the sedimentation tank. use efficiently
