A gravity water purification device

Abstract

The invention relates to a gravity type water purification device, which relates to the technical field of water purification treatment. Since the water purification capacity of the existing water purification device is not adjustable, it is more likely that the purified water is still mixed with a lot of particles Case. This scheme includes the flocculation area, the water purification sedimentation area and the fine filtration area in sequence along the water flow direction. The water flow direction of the water purification sedimentation area is from bottom to top. There are several arrays of water purification channels fixed in the water purification sedimentation area. The water channel is arranged obliquely; two parallel connecting frames are installed in the water purification sedimentation area, and several adjusting pieces are fixedly connected between the two connecting frames. Each adjusting piece corresponds to a water purification channel, and the adjusting piece passes through the corresponding The water purification channel is attached to the inner wall of the water purification channel; a drive assembly is installed in the water purification sedimentation area. The driving assembly can make the adjusting sheet stick to the inner wall of the water purification channel or be away from the inner wall, thereby changing the hydraulic radius of the water purification channel, thereby changing the water purification capacity.

Description

technical field [0001] The invention relates to the technical field of water purification treatment, in particular to a gravity type water purification device. Background technique [0002] At present, in water treatment projects, in order to remove suspended solids and reduce turbidity in raw water, the water purification process of coagulation sedimentation filtration is usually used. The three basic processing units of flocculation, sedimentation and filtration are organically combined into one, collectively referred to as an integrated water purifier. [0003] For example, the integrated water purifier whose application publication number is CN102153178A includes a flocculation reaction zone, an inclined tube sedimentation area, a sludge concentration area, and a backwashing area, and an inclined tube is arranged in the inclined tube sedimentation area. The sewage to be purified is flocculated in the flocculation reaction zone, and is precipitated and separated in the i...

AI Technical Summary

Problems solved by technology

[0004] However, there are deficiencies in the above-mentioned water purification methods. Since the inclined tubes or inclined plates in the inclined tube sedimentation area are fixed in the purification tank, the water purification capacity of the water purification device is fixed. , the particulate matter content in the sewage discharged into the purification tank is relatively high, and the above-mentioned water purification devices often cannot achieve water purification well, which leads to a lot of particulate matter mixed in the discharged "clean water"
