Combined type water clarifying device

Abstract

The invention improves a water clarifying device. The device is characterized in that a coagulation reaction area comprises a cylinder with the upper end thereof enclosed and a tangential water inlet pipe; a rotatable mud-scraping device is driven by a central shaft; a filtering area is arranged inside an upper accelerating settlement separating area; the filtering area is provided with a casing pipe along the vertical direction, through which a spindle of a rotatable mud-scraper can pass; and a water-receiving pipe is arranged on the filtering upper part along the radial direction. Through once automatically flowing treatment, the clarification and filtering process can be finished, which meets the high demand of discharged water and amplifies the function of a clarifying pool. The rotatable mud-scraper is provided with vertical grids for stirring and concentrating, through which the four functions of coagulation, separating sedimentation, concentration and filtering can be performedone by one in one clarifying pool. Through the adjacent treating processes and the combination of upper and lower parts, not only the four treating functions can be performed but also the treating device can be compacted, which saves more than 20% of the occupied area and decreases more than 50% of the power consumption.

Description

technical field [0001] The invention is an improvement to a water treatment clarification device, in particular to a combined water clarification device capable of simultaneously realizing the functions of clarification, concentration, precipitation and filtration in the same clarification device. Background technique [0002] Water treatment clarification is mainly used for sediment water separation and water clarification treatment such as surface water, high turbidity raw water, sewage treatment and reuse treatment, etc. The purpose is to separate mud sand, suspended solids and water, so that the treated water can be quickly clarified . In order to achieve rapid clarification, the prior art mostly adopts a mechanical agitation clarifier that combines mixing, flocculation reaction and sedimentation processes in one device or tank. The basic structure is as follows: figure 1 shown. The basic structure and working process are as follows: the middle area of ​​the treatment ...

AI Technical Summary

Problems solved by technology

[0008] Therefore, most of the above-mentioned existing technologies involve the improvement of coagulation, omitting the improvement of mechanical agitation, but the only basic function is still only sedimentation, separation and clarification, which can only achieve sedimentation and removal of mud, sand and larger suspended matter in water. However, this is not the case in water clarification treatment. Often it is still not enough. For higher requirements, the filter function still needs to be set separately in the follow-up, and the shortage of setting the filter area in the rear still exists.
