High-efficiency reactive sedimentation device for water treatment

Abstract

The invention discloses a high-efficiency reaction sedimentation device used in water treatment, which is especially suitable for installation on integrated water treatment equipment. It consists of upper and lower parts. The chamber of the conical funnel-shaped structure is a sludge hopper, and there is a sandwich chamber structure in the wall of the settlement area. The interlayer chamber is the reaction area, and one end of the reaction area has a sedimentation reaction There is a water inlet of the reactor, the other end has a water outlet of the reaction zone, a water outlet of the sedimentation reactor is opened on the top of the sedimentation zone, and a sewage outlet of the sedimentation reactor is opened at the lower part of the sludge hopper. Compared with the traditional sedimentation tank, it has fast and efficient It can complete the settlement of a large amount of water, has the advantages of good effect and small volume; and can satisfy the use of the integrated water treatment equipment proposed by the inventor.

Description

technical field [0001] The invention discloses a high-efficiency reaction sedimentation device used in water treatment, which is a new type of water treatment sedimentation device, and is especially suitable for being installed on integrated water treatment equipment and used as a part of the integrated water treatment equipment. Background technique [0002] With the rapid development of China's economy, China's industry, agriculture, animal husbandry, cities and other aspects are developing rapidly, accompanied by serious environmental pollution problems, especially water pollution problems. [0003] Due to people’s insufficient anticipation of the negative impact of rapid economic development and poor prevention, the direct result is the shortage of clean water resources, water pollution, and the deterioration of the water environment for future generations. Natural purification through natural diffusion, dilution, redox, biodegradation, etc. The way has been unable to ke...

Problems solved by technology

[0007] However, the traditional livestock breeding water treatment scheme cannot meet the needs of the rapid development of the breeding industry. Different traditional schemes have different problems in different aspects:

[0008] Traditional livestock breeding wastewater treatment scheme (excluding pretreatment, such as grille, grit chamber, sump, etc.), hydrolytic acidification tank plus aerobic activated sludge treatment, the effluent quality of this scheme is good after treatment, but there are land occupations Large area (15-20 square meters / ton of water), many treatment structures, water investment is generally 3000-5000 yuan / ton, operating cost is 0.8-2.5 yuan / ton of water, large amount of sludge, complex management and maintenance, cost high;

[0009] Traditional anaerobic plus contact oxidation treatment, the effluent water quality after treatment is better, and the effect of impact load resistance is good. Due to the anaerobic treatment, the amount of sludge is greatly reduced, but there is a large area (15-20 square meters / ton of water) , which is basically the same as hydrolytic acidification plus aerobic activated sludge treatment. Although anaerobic treatment requires a longer residence time, the contact oxidation treatment time is slightly shorter than that of activated sludge, so the two occupy almost the same area. About 3500-6000 yuan / ton, the operating cost is also 0.8-2.5 yuan / ton of water, and the operation and management are complicated and troublesome;

[0010] Traditional anaerobic plus biological stabilization pond treatment, the effluent water quality after treatment is good, can withstand impact load, the investment per ton of water is small, about 2000-3000 yuan / ton, and the operating cost is low, about 0.5-2.5 yuan / ton The amount of water and sludge is small, but due to the biological stabilization pond, it occupies the largest area, generally 30-60 square meters per ton of water, suitable for the transformation of abandoned ponds in rural areas, otherwise it cannot be used, and the sanitary conditions are very poor , the stable pond breeds mosquitoes and flies, etc.;

[0011] The traditional UASB plus CASS plus artificial rapid infiltration treatment, the water quality after treatment is good, can withstand impact load, and the operating cost is relatively small, about 0.8-1.6 yuan / ton of water, but it occupies a large area, about 15-25 square meters m / ton of water, complex operation and management, need to cooperate with automation equipment, large investment, water treatment needs 4000-5000 yuan / ton;

[0012] The traditional oxidation ditch treatment, the effluent water quality after treatment is good, can withstand impact load, and the operating cost is 0.8-2 yuan / ton of water, but the area is relatively large, generally 18-30 square meters / ton of water, the investment It is about 4000-5000 yuan / ton of water. The quality of effluent water will be affected by temperature changes, and the operation is more complicated;

[0013] Faced with the deterioration of the above-mentioned water environment, the traditional water treatment methods can no longer meet the current situation of China's rapid economic development. After more than ten years of research, the inventor proposed the concept of integrated water treatment equipment, which can well control water bodies Pollution, such as: treatment of livestock and breeding wastewater, treatment of urban domestic sewage, etc.
