Problems solved by technology

However, natural sedimentation not only takes a long time, but usually there are thick sedimentation and stagnant areas in the water body, with a lot of suspended solids and chaotic water body. Therefore, the static sedimentation tank has a large area, small effective pool volume, difficult mud discharge, and low treatment efficiency. shortcoming

Embodiment Construction

[0026] exist figure 1 In the shown embodiment, hinges are provided at the bottom of the center of gravity of the movable pool body to connect with the fixed base, supporting the left and right sides of the hinge, and two groups of hydraulic tilting systems are symmetrically distributed, and their hydraulic rods are respectively hinged with the pool body.

[0027] After the raw water is injected, put the pool body and the raw water horizontally for a certain period of time to eliminate the waves or turbulence generated when the raw water enters the pool.

[0028] When the turbulent flow of the raw water is eliminated and the colloid in the water reaches the critical state of destabilization, start the hydraulic tilting system, and the left and right hydraulic rods will move towards each other alternately, tilting the pool body to one side at a certain speed to reach the set angle of tilting; The speed tilts the pool body in the opposite direction, and the period of tilting the ...

Abstract

Provided is an oscillatory type sewage sedimentation basin, which utilizes a tilting system to tilt a movable basin, so as to generate gradient tangential deformation and resonance on raw water, promote a flocculation reaction and improve sewage treating effect, and an operation method thereof. The movable sedimentation basin is jointed with a pedestal hinge and can tilt around the hinge under a tilting operation of the tilting system. When sewage reaches a destabilization critical state, the tilting mechanism is started to tilt the movable basin to generate gradient tangential deformation on the raw water and promote the flocculation reaction. A basin tilting period is controlled to generate resonance oscillation on the raw water. The resonance promotes fully conduction of the flocculation reaction, so as to purify the raw water repeatedly, separate the settlement thoroughly and reduce suspensions. The settlement progress consumes a short time and energy, has good effect and low costs and is green, environment-friendly and easily operated.

Description

technical field [0001] The invention relates to an oscillating sewage settling tank capable of accelerating the sedimentation process in sewage treatment, clarifying water body and improving sewage treatment effect and its operation method. Background technique [0002] In recent years, with the rapid development of my country's economy, the discharge of urban sewage has continued to increase, and the urban water environment has been seriously polluted. The sewage problem has become a serious environmental and economic problem in China. Due to the high cost of sewage treatment and unsustainable financial investment, the rate of sewage treatment in my country is very low. The cost and efficiency of sewage treatment have greatly restricted the development of sewage treatment industry. Therefore, researching and developing low-cost, fast-speed and high-efficiency new sewage treatment processes and new equipment is the development direction of the sewage treatment industry. [...
