Embodiment Construction

[0016] The structure and operation mode of the moving bed filter of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The raw water enters the filter tank 2 from the water inlet 1, and after being distributed by the water distributor 21, it flows upward evenly and passes through the filter bed layer 3, and the suspended solids and other pollutants in the water are trapped in the filter material. The filtered clean water enters the clean water storage area 4 on the upper part of the filter tank, enters the water outlet area 5 after overflowing, and is discharged through the water outlet 6 .

[0018] While filtering the raw water, the filter material of pollutants is trapped in the lower part of the filter tank 2, and under the action of gravity, it continuously moves downwards, passes through the rectifier 7, the filter material outlet 8, and then passes through the air distributor 10, 22, 24 and Under the action of th...

Abstract

A moving-bed filter able to continuously run for treating water is composed of cylindrical tank, water distributor, filtering bed, fairing unit, air distributor, filtering material delivering pipe, gas separator, washer, filtering material distributor and the regulating valve for the washing water.

Description

technical field [0001] The invention relates to a water treatment device, more specifically a filter device for removing suspended solids in water, especially a moving bed filter capable of continuous filter operation. Background technique [0002] As one of the means of removing suspended solids in water, filtration is not only widely used in urban or industrial sewage advanced treatment and sewage reuse treatment, but also in urban and industrial water supply treatment ( Such as tap water, industrial fresh water, boiler feed water), circulating cooling water treatment and other processes commonly used equipment. [0003] The mechanism of the filter to remove suspended solids is mainly to use the tiny pores inside the filter bed to trap particulate pollutants in the water. Its working process includes two processes: filtration and filter material cleaning. According to different conditions such as filter material, filtration speed, water flow direction, bed depth, water fl...
