Water purifying device

Abstract

The invention belongs to the technical field of sewage treatment devices, particularly relates to a water purifying device capable of processing the high-turbidity water, and aims at providing a water purifying device integrating the coagulation, settlement and filtering, occupying a small land area and ensuring the stable water quality. The technical scheme adopted by the invention is as follows: the water purifying device comprises a cyclone mixing reaction area, a high-efficiency oblique plate settling area and a shallow-layer filtering area and is a continuous concentric reactor, the upper part of a water purifying device body is a cylindrical shell, the lower part of the device body is a conical shell, the middle part of the cylindrical shell is a circular filtering pond which is concentric with the cylindrical shell, and an area defined by the conical shell is the cyclone mixing reaction area.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment devices, and in particular relates to a water purification treatment device capable of treating high turbidity water. Background technique [0002] The sedimentation process forms used in sewage treatment mainly include advection tanks, small-space inclined plate and inclined tube sedimentation tanks, etc. Among them, the inclined plate with small spacing and the inclined tube sedimentation tank fully embody the advantages of the shallow tank, and the sedimentation efficiency is very high, and the smaller the distance between the inclined plates, the higher the sedimentation efficiency. However, in practical applications, after a period of operation of the inclined plate sedimentation tank with a small inclined plate spacing, or when the water quality and quantity change, its sedimentation efficiency and effluent water quality will drop significantly, resulting in serious mud accumulation...

AI Technical Summary

Problems solved by technology

However, in practical applications, after a period of operation of the inclined plate sedimentation tank with a small inclined plate spacing, or when the water quality and quantity change, its sedimentation efficiency and effluent water quality will drop significantly, resulting in serious mud accumulation and blockage between the inclined pipe and the inclined plate. Even collapsed inclined pipes and inclined plates

Therefore, many water plants use advection pools that occupy a large area and have low efficiency, but are quite stable in operation.

The main reason for the above problems is that for the inclined tube sedimentation tank, its hexagonal structure is not conducive to mud discharge.

For inclined plate sedimentation tanks, since the smaller the spacing, the higher the sedimentation efficiency, it is often used in inclined plate sedimentation tanks with smaller spacing, but when the spacing of the inclined plates is reduced, the mud discharge will not be smooth, which will lead to Mud and blockage

[0003] In addition to these deficiencies, when the existing technology is used to directly purify high-concentration sewage, the quality of the effluent water can reach the "Discharge Standard of Pollutants for Urban Sewage Treatment Plants" GB 18918-2002 Class A Standard, very few, even Those who can barely meet this standard are generally complex in structure, high in precision, high in cost, or use a large amount of chemicals, or have short backwashing cycles and high energy consumption.
