Anti-floating filter plate of upward flow suspension filter material filter pool and preparation and installation method thereof

Abstract

The invention relates to a preparation and installation method of an anti-floating filter plate of an upward flow suspension filter material filter pool. The method is characterized by comprising the steps of assembling a mold to prepare the anti-floating filter plate and installing the anti-floating filter plate. The anti-floating filter plate comprises an anti-floating filter plate body of a rectangular reinforcing steel bar concrete plate structure. Upper and lower rabbets are formed at the opposite ends of the two side ends of the anti-floating filter plate. The cross section of the upper rabbet is in a dovetail groove shape, the cross section of the lower rabbet is in a dovetail shape matched with the dovetail groove shape of the upper rabbet, and two adjacent anti-floating filter plate bodies form a dovetail type plate slot through engagement of the upper and lower rabbets; a plurality of filter head sleeves are preformed in the axial direction of the anti-floating filter plate. The anti-floating filter plate has the advantages that the rabbet structure is adopted, the problem that formwork supporting is difficult in the plate slot construction process is solved, and the problems of water leakage, material leakage, difficult pouring and difficult formwork supporting are solved; the anti-floating effect is well achieved by taking full advantage of the weight of the anti-floating filter plate and the pressure relief effect of filter holes.

Description

technical field [0001] The invention belongs to a sewage treatment system, and in particular relates to a preparation and installation method of an anti-floating filter plate of an upward flow suspension filter material filter tank and an anti-floating filter plate. Background technique [0002] At present, the commonly used filter tanks in engineering are basically sewage flowing down through the filter material layer for filtration, and the filter material is placed on the filter plate. Since the density is greater than that of water, the filter plate needs to bear the weight of the filter material. Sewage permeates the filter material and flows to the lower part of the filter tank through the filter holes on the filter plate, and then flows out of the filter tank to achieve the filtering effect. ZL201220010133 discloses an upward flow suspension filter, which includes four functional areas: raw water area, water distribution area, filtration area and clear water area. S...

AI Technical Summary

Problems solved by technology

However, since the density of the filter material is less than that of water, once the filter material flows out, it will not only pollute the environment, but also the filter will lose its filtering effect.
