Integrated clarifier based on vortex grid coagulation and water treatment method thereof

Abstract

The invention discloses an integrated clarifier based on vortex grid coagulation and a water treatment method thereof, wherein the integrated clarifier comprises: a vortex reaction chamber, a grid reaction chamber and a precipitating chamber, the three chambers are arranged side by side and form an integrated structure, raw water flows from the top of the vortex reaction chamber into the clarifier and flows sequentially through the vortex reaction chamber, the grid reaction chamber and the precipitating chamber before being treated into clear water, and the clear water flows from the bottom of the precipitating chamber out of the clarifier. The integrated clarifier has the advantages that micro-vortex flocculation, small-grid flocculation and small-tilt inclined plate precipitation and separation are integrated, the raw water added with a coagulating agent forms micro-vortex cooperative coagulation through micro-vortex flocculation and small-grid flocculation, cooperation of micro-vortex with coagulation helps diffuse particles in water, chances for instable colloidal particles to collide are increased, and a solid-liquid two-phase system with better flocculating quality, high density and good separating property is formed; therefore, the integrated clarifier may be applied to water treatment to provide significantly improved coagulation.

Description

technical field [0001] The invention relates to a clarifier and a method for treating water thereof, in particular to an integrated clarifier based on vortex grid coagulation and a method for treating water thereof, and belongs to the technical field of environmental protection. Background technique [0002] The clarifier is a structure that integrates the flocculation reaction process and the clarification and separation process. At present, many clarifiers commonly used in my country's water treatment are facing problems such as aging, low water production efficiency, and poor effluent quality. Therefore, there is an urgent need to transform the existing technology to meet the needs of users for water quantity and water quality under the new situation. [0003] Most of the research work on the improvement of clarifiers in foreign countries focuses on the thickness of suspended sludge layer, sludge return and discharge, and automatic control of clarifiers. For example, th...

Problems solved by technology

However, the construction cost of the sedimentation tank is relatively high, and mechanical equipment such as return pumps and mixers need to be added, and the anticorrosion of the equipment in the treatment of highly corrosive water must also be considered, so it brings certain difficulties and resistance to practical application. limit the scope of its application
