Embodiment 1

[0021] The floating filtration integrated treatment system of embodiment 1, such as figure 1 As shown, it includes an integrated treatment tank 1, a dissolved air subsystem 2, a slag scraping subsystem 3 and a filtration subsystem 4. The front side wall of the integrated treatment tank 1 is provided with a water inlet 11, and the integrated treatment tank 1 is installed with Upright dividing plate 12, the bottom of dividing plate 12 is fixed on the pool bottom of integrated treatment pool 1, dividing plate 12 is arranged along the width direction of integrated treatment pool 1, and the height of dividing plate 12 is less than integrated treatment pool 1, dividing plate 12 Divide the inner cavity of the integrated treatment pool 1 into a dissolved air area 13 and a filter area 14, the dissolved air area 13 is close to the water inlet 11, the dissolved air subsystem 2 and the slag scraping subsystem 3 are respectively installed on the integrated treatment pool 1, The air outlet ...

Embodiment 2

[0027] The floating filtration integrated treatment system of embodiment 2 differs from embodiment 1 in that in embodiment 2, as image 3 As shown, the front side of the mounting plate 15 is fixed on the partition 12, the bottom surface of the mounting plate 15, the rear side of the partition 12, the rear side of the slag retaining plate 16, and the bottom wall and the rear side wall of the integrated treatment tank 1 Enclose the catchment area 18; the front side of the installation plate 15 is the first slant plate 154 obliquely towards the bottom of the filter area 14 from front to back, and the bottom of the rear side wall of the integrated treatment pool 1 is an oblique collection area from back to front. The second inclined plate 155 at the bottom of the water area 18 and the water outlet 61 are arranged on the side of the sump 6 .

Embodiment 3

[0028] The difference between the floating and filtering integrated treatment system of embodiment 3 and embodiment 1 is that in embodiment 3, the filtration subsystem 4 includes a filter frame 41 and a suction and washing device, and the filter frame 41 is equipped with a filter cloth 42, and the suction and washing device It includes a suction cup 43 connected to a suction cup driving device 44 , the suction cup 43 is arranged outside the filter frame 41 , and the suction cup 43 is used for sucking away the filtered material on the filter cloth 42 . Wherein, the filter frame can adopt "a filter core frame" disclosed in ZL 200920122818.5, and the suction and washing device can adopt the "suction and washing device for filter tank" disclosed in ZL 200910100890.2.

Abstract

The invention discloses a floating and filtering integrated treatment system which comprises an integrated treatment tank, a gas dissolving subsystem, a slag scraping subsystem and a filtering subsystem, and a water inlet is formed in the side wall of the front side of the integrated treatment tank; the inner cavity of the integrated treatment tank is divided into a gas dissolving area and a filtering area by the partition plate; the gas outlet pipe of the gas dissolving subsystem extends into the gas dissolving area; the filtering subsystem is installed on an installation plate, a slag blocking plate is installed on the rear side of the installation plate, water collecting areas are arranged on the lower side of the installation plate and the rear side of the slag blocking plate, a slag falling groove is formed in the rear side of the filtering subsystem, the slag scraping subsystem comprises a slag scraping plate, a water collecting groove is fixed to the rear side wall of the integrated treatment pool, and a water outlet is formed in the water collecting groove. According to the floating and filtering integrated treatment system, an air floatation tank and the filtering tank areorganically combined in the integrated treatment tank, a complementary effect is achieved, the defects of a single air floatation tank or a single filtering tank are overcome, the effects of saving land, energy, materials and equipment are achieved, the stable effluent quality can be guaranteed, and the water treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated floating and filtering treatment system. Background technique [0002] Air flotation and filtration are two different solid-liquid separation methods. In traditional applications, the air flotation pool and the filter pool are combined. Generally, the air flotation pool and the filter pool are separately set up and then connected in series, that is, the front process is air flotation, and the subsequent process is filtration. Both light and heavy suspended solids are removed to improve the water quality after treatment. However, the disadvantage of this series method is that it occupies a relatively large area, requires a large number of equipment and supporting units, and has high operation and maintenance costs. For example, CN107151085A discloses a kind of sewage integrated treatment device, including coarse filter tank, heavy metal removal tank, air fl...
