Circulating clarification equipment

Abstract

The invention discloses circulating clarification equipment. The equipment comprises a cylindrical clarifying barrel, wherein a flow guide barrel, wherein a flow dividing barrel, a flocculation barrel and a flow pushing barrel are coaxially arranged in the clarifying barrel, and the diameters of the flow guide barrel, the flow dividing barrel, the flocculation barrel and the flow pushing barrel are sleeved from small to large; wherein the shunting cylinder is arranged above the guide cylinder, and both the shunting cylinder and the guide cylinder are arranged in the flocculation barrel; the lower part of the flocculation barrel is sealed by an arc-shaped bottom, and windows communicated with the plug flow barrel are uniformly formed in the circular side wall of the upper part in a surrounding manner; stirring blades are arranged in the guide cylinder and are fixed on the inner side wall of the flocculation barrel through a plurality of connecting plates on the outer side wall. According to the circulating clarification equipment, a coaxial five-cylinder layout structure is adopted, the annular water passing channel can be formed on the periphery of each cylinder. Compared with a pipeline or a single-side water passing structure of a rectangular pool in the prior art, the annular water passing channel has the largest water passing sectional area under the same volume and highest water production capacity per unit volume, and the energy consumption per unit water yield can be controlled to be lower.

Description

technical field [0001] The application relates to a sewage treatment equipment, in particular to a circulating clarification equipment with compact structure, small footprint and high treatment efficiency. Background technique [0002] The clarifier is a device for coagulating water and removing suspended solids and colloids in water. The coagulation treatment process of sewage includes three stages: mixing of water and chemicals, reaction and separation of flocs and water. The clarifier is a special equipment that completes the above three processes in one. Existing water treatment equipment is usually composed of sedimentation tanks, coagulation tanks, flocculation tanks, clarification tanks, etc. The sewage is processed through the above-mentioned pools in sequence, and the added chemicals such as coagulants, flocculants, etc. The harmful components of the waste water are transformed into solids and settle to the bottom of the pond, and finally clear water that meets th...

AI Technical Summary

Problems solved by technology

However, the mud accumulation area at the bottom is blocked by the upper structure in the overlapping area, making dredging difficult

In addition, due to structural differences in the water outlet areas on both sides, it is easy to have inconsistent water quality.

[0005] In short, in order to solve the problem of large footprint of water treatment equipment, the existing technology provides various solutions listed above, but these solutions still have the problems of low treatment efficiency and difficult sludge cleaning
