RG-type vertical sedimentation and air-floatation integration water purifier

Abstract

The invention relates to a RG-type vertical sedimentation and air-floatation integration water purifier. The RG-type vertical sedimentation and air-floatation integration water purifier comprises an air-floatation tank, a chemical feeding tank, an inclined tube sedimentation tank, a clean water tank, a reaction tank, a clapboard reaction tank, a water distribution tank and a sludge sedimentation collection tank, wherein a dissolved gas pipe, an air-floatation sludge discharge pipe, an air-floatation clean water pipe, an air-floatation blow-down pipe, a water inlet pipe, an exhaust pipe, an inclined collector pipe, a sludge scraping device and a slope gas collection bottom plate are distributed in the air-floatation tank; an air pipe is arranged in the chemical feeding tank; an inclined blank pipe is arranged in the inclined tube sedimentation tank, and a clean water discharge pipe and a reinforced flange are distributed in the clean water tank; a perforated pipe, a chemical feed pipe, a charging inlet hole cover, a reaction chamber blow-down pipe and a reaction chamber sludge discharge blow-down pipe are distributed in the reaction tank; a water distribution pipe is distributed in the water distribution tank; the inclined sludge discharge pipe is distributed in the sludge sedimentation collection tank; and the eight treatment tanks are ingeniously arranged in one tank body to form a whole body. The RG-type vertical sedimentation and air-floatation integration water purifier has the advantages of simplified process flow and structure, little investment and long service life, simple equipment and convenience in transfer and installation and small area occupation.

Description

Technical field [0001] The invention relates to a purification equipment for wastewater treatment, in particular to an RG type vertical precipitation air floatation integrated water purifier. Background technique [0002] At present, the traditional wastewater treatment purification equipment generally adopts the finalized vertical flow sedimentation tank and the air flotation equipment matching wastewater treatment purification system. The design adopts separate unit equipment, and the equipment is connected in series. Therefore, the equipment occupies a large area, consumes a lot of materials, and the system is complicated, which is not convenient for equipment maintenance and management. [0003] In addition, the most popular wastewater treatment equipment in the prior art is an integrated air flotation equipment, which is mostly a separate type of processing units or a combined type of partial units. But its shortcomings have three points: one is that the split type covers a l...

Problems solved by technology

[0002] At present, the traditional purification equipment for wastewater treatment generally adopts a wastewater treatment and purification system that matches the established vertical flow sedimentation tank and air flotation equipment. In the design, separate unit equipment is used, and the equipment is connected in series. Therefore, the equipment occupies a large area, consumes a lot of materials, and the system is complicated, which is not convenient for equipment maintenance and management

[0003] In addition, the most popular wastewater treatment equipment in the prior art is comprehensive air flotation equipment, which is mostly a separate type of treatment unit or a combination of some units.

But there are three disadvantages: first, the split type occupies a large area and is expensive, especially affecting the plant area; second, it is complicated to manage and realize automatic operation; third, it has incomplete functions
