Embodiment 1

[0046] like figure 1 , figure 2 and image 3 The shown horizontal flow sand filter is composed of a tank body 1, a raw water inlet component, a sand filter bed 4, a filtered water outlet component, an aeration component and a backwash component. The function of the raw water inlet component is to send the raw water into the sand filter bed and distribute it evenly.

[0047] The pool body 1 is rectangular and the material is concrete;

[0048] The raw water inlet assembly is composed of a water inlet pipe 2 and a water distribution device 3 connected to the water inlet pipe. A valve is set on the water inlet pipe 2 to introduce the raw water into the horizontal flowing sand filter; the water distribution device 3 is composed of four water distribution devices. The standpipes and the water distribution standpipes are evenly distributed with water outlet channels, and each water distribution standpipe is vertically arranged in the sand filter bed 4 and evenly distributed. The ...

Embodiment 2

[0060] A horizontal sand filter, comprising a pool body 1, a raw water inlet component, a sand filter bed 4, a filtered water outlet component, a backwash component and an aeration component. The specific structure of the horizontal sand filter is the same as that of Embodiment 1, with the exception of the difference. in:

[0061] like Figure 4 As shown, the tank body 1 is divided into 4 circular areas, corresponding to 4 water distribution devices 3 respectively. The circular areas are distributed in a rectangular shape, and a sand filter bed and a water distribution device are arranged in a circular area; The water inlet pipes 2 in the assembly are respectively connected with four water distribution devices 3; The bottoms of the four water distribution risers are respectively connected with the sewage pipes.

[0062] The filtered water outlet assembly is composed of a water collector 5 and a water outlet pipe 7; the sieve plate 51 described in the water collector 5 is a c...

Abstract

The invention relates to a horizontal flow sand filter pool and a water treatment technique thereof. The horizontal flow sand filter pool comprises a pool body, a raw water inlet component, a sand filter bed, a filtered water outlet component, an aeration component and a back washing component, wherein the raw water inlet component comprises a water inlet pipe and a water distribution device used for sending raw water into the sand filter bed; the water inlet pipe is connected with the water distribution device; the water distribution device is arranged in the sand filter bed; a plurality of water outlet pore channels are uniformly distributed on the vertical face of the water distribution device; the filtered water outlet component comprises a water collector and a water outlet pipe; a water inlet pore channel is arranged on one side of the water collector, which is adjacent to the sand filter bed; the water outlet pipe is communicated with the water collector; the back washing component comprises a back washing pipe and a sewage discharge pipe; the back washing pipe is connected with the water outlet pipe; the sewage discharge pipe is connected with the water distribution device. The horizontal flow sand filter pool is large in filtration area, sand grains are washed thoroughly, and water and energy are saved; in addition, extensive application is diversified, so that the horizontal flow sand filter pool can not only be filter equipment simply, but also become an aerobiotic / anoxic biological filter pool integrating functions of biological contact oxidation and suspended matter filter bed interception.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a horizontal flow sand filter tank and a water treatment process thereof. Background technique [0002] Sand filter is a typical filter layer filtration equipment, which uses the surface area provided by the granular material of the filter layer to retain solid particles and colloids in the water to clarify the water. The sand filter can retain impurities in the water with a particle size far smaller than that of the filter material, mainly through contact flocculation, followed by sieving and sedimentation. Due to the advantages of large decontamination capacity, long working cycle and reliable operation, sand filters are widely used in water supply treatment or advanced treatment of sewage after secondary treatment. [0003] The operation of the sand filter is mainly the circulation of the two processes of filtration and backwashing. In the existing sand filter tank, the raw wat...
