Flocculation-precipitation integrated reactor for water treatment

Abstract

The invention relates to a flocculation-precipitation integrated reactor for water treatment, belonging to the technical field of water treatment. The flocculation-precipitation integrated reactor for water treatment comprises an outer tube, an inner tube, a water distributor and a perforation plate, wherein the bottom of the outer tube is funnel-shaped, a precipitate outlet is formed in the bottom of the outer tube, a water outlet of the integrated reactor is formed in the tube wall of the upper part of the outer tube, the inner tube is arranged in the outer tube, the top of the inner tube is fixed on a cover of the outer tube, the water distributor is arranged on the upper part of the inner tube, and a backwashing water outlet is formed in the cover on the top of the inner tube. The perforation plates are fixed in the inner tube in parallel, the bottom of the inner tube is funnel-shaped, a precipitate outlet is formed in the bottom of the inner tube and connected with a backwashing valve and a sludge discharge valve. Aeration heads are arranged on the lower parts of a plurality of perforation plates in the inner tube, and perforations are formed in the inner tube wall on the upper parts of the aeration heads. The integrated reactor integrates flocculation and precipitation, so that the occupation area for water treatment can be reduced, the energy consumption of the water treatment can be decreased, the water treatment cost can be lowered, and the flocculation-precipitation integrated reactor has wide application prospects and is especially applicable to wide remote rural areas.

Description

technical field [0001] The invention relates to a flocculation-sedimentation integrated reactor for water treatment, belonging to the technical field of water treatment. Background technique [0002] The drinking water purification field at home and abroad already has a relatively mature technology, but due to economic backwardness and other rural and remote areas, water supply measures are still quite backward, because it is not suitable to build waterworks in many rural and remote mountainous areas, and it is not suitable to build large structures, occupying an area of A variety of limiting factors such as operating costs make the development of small water supply equipment a major task in the current water supply field, and it is also facing great challenges. [0003] Conventional drinking water treatment processes, namely coagulation, sedimentation, filtration, and disinfection processes, can effectively remove turbidity and organic matter in water, but the existing trea...

[0002] The drinking water purification field at home and abroad already has a relatively mature technology, but due to economic backwardness and other rural and remote areas, water supply measures are still quite backward, because it is not suitable to build waterworks in many rural and remote mountainous areas, and it is not suitable to build large structures, occupying an area of Various limiting factors such as operating costs make the development of small water supply equipment a major task in the current water supply field, and at the same time face greater challenges

[0003] Conventional drinking water treatment processes, namely coagulation, sedimentation, filtration, and disinfection processes, can effectively remove turbidity and organic matter in water, but the existing treatment processes require the construction of flocculation tanks and sedimentation tanks, which occupy a large area and are not suitable for Small area water supply in rural and remote areas
