A movable sedimentation basin convenient to clean and used for wastewater treatment

Abstract

The invention relates to the technical field of water treatment, and particularly relates to a movable sedimentation basin convenient to clean and used for wastewater treatment. The sedimentation basin includes a rainproof cover, a sedimentation basin main body, electric telescopic bars, a supporting bar, a bearing plate and idler wheels. The rainproof cover has a rectangular structure. A water feeding pipe penetrates the left side surface of the sedimentation basin main body, and a water discharging pipe is disposed at the right side surface of the sedimentation basin main body. Rotating shafts are disposed right above the water feeding pipe and the water discharging pipe. Bottoms of free ends of the rotating shafts are provided with the electric telescopic bars a. The inside bottom of the sedimentation basin main body is provided with a scraping plate. The bottom of the sedimentation basin main body is connected to the bearing plate through the electric telescopic bar and the supporting bar. Bottom four corners of the bearing plate are provided with the idler wheels. The sedimentation basin can avoid basin structure damage caused by long-term solarization and acid rain erosion, thus prolonging the service lifetime of the sedimentation basin. The sedimentation basin is convenient to clean, and has advantages of good mobility and capability of saving the cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a convenient cleaning and movable sedimentation tank for sewage treatment. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Use the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The sedimentation effect depends on the flow rate of the water in the sedimentation tank and the residence time of the water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube counterflow sedimentation tanks, accelerated clarifiers, pulse clarifiers, etc. are currently used. Sedimentation tanks are widely use...

AI Technical Summary

Problems solved by technology

[0005] 1. The sedimentation tank is set outdoors. Long-term exposure to the sun and erosion by rain (especially acid rain) will damage the structure of the sedimentation tank and shorten its service life.

[0006] 2. The cleaning of the sedimentation tank is troublesome. Usually, the interior of the sedimentation tank is cleaned manually, which is a waste of time and manpower.

[0007] 3. The sedimentation tanks are all fixed on the ground, which makes the sedimentation tanks immobile. If it is necessary to treat water in other areas, it is necessary to build a separate sedimentation tank, which not only increases the cost of investment, but also consumes manpower and time.
