Denitrification and sludge age dephosphorization purification equipment by domestic sewage breakpoint oxidation method

Abstract

The invention discloses a domestic sewage breakpoint oxidation method denitrogenation and sludge age dephosphorization purification device. The structure of the device comprises a side machine table seat, a shear gear box, a belt machine box, a sedimentation tank, a traction wheel seat, a filtering tank and a denitrogenation and dephosphorization tank. The device realizes the combination of the filtering tank and the denitrogenation and dephosphorization tank to further realize breakpoint oxidation extraction of nitrogen by using a physical acid-proof structure to form a gas-liquid separationeffect, the gradual oxidation extraction effect guided by interval nodes in a water body can be achieved by breakpoint aeration, sludge can be fallen down by skidding and developing, phosphorus- containing solid matters in water can be settled intuitively, a bottom round table brush body moves horizontally to remove pool bottom solid impurities to achieve solid-liquid separation effect, the innerwall of a quadrate pool body forms a water-injection sliding lining isolation inner wall effect through a sliding isolation lining board, a protection is provided for the pool body of the domestic sewage treatment device. In addition, by cooperation with sedimentation, a solid lower baffle is thickened and resistant to pressure, so that the physical purification operation of the water body can berealized.

Description

technical field [0001] The invention is a domestic sewage break point oxidation method denitrification and sludge age phosphorus removal purification equipment, which belongs to the field of domestic sewage treatment. Background technique [0002] Domestic sewage is a mixed sewage body formed by people washing fruits, vegetables and meat in the kitchen and bathing in the toilet. The water quality is mixed with various pollutants, and further sewage treatment is required to purify the water body, and realize the reuse operation of water cycle, so that household water and life Water saving and circular purification treatment operation, the shortcomings of the current technology to be optimized are: [0003] Nitrogen and phosphorus sewage mixed in daily life is a chemically acidic water body, which is easy to corrode a certain amount of sedimentation tank or filter tank inner wall surface, making the pool wall thinner, easy to cause water seepage and leakage, and adding chemica...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a domestic sewage breakpoint oxidation method for denitrification and sludge age phosphorus removal purification equipment to solve the problem that the mixed nitrogen and phosphorus sewage in daily life is a chemically acidic water body. It is easy to corrode a certain amount of sedimentation tank or the surface of the inner wall of the filter tank, making the pool wall thinner, which is easy to cause water seepage and leakage, and adding chemical substances alkaline to the sewage treatment to neutralize and settle or extract and remove them will be added invisibly Other elemental substances enter the water body, causing various element ions and atoms to be contained in the gaps of water molecules, which interferes with the purity of the water body, and also increases the difficulty of sewage treatment and purification. Multi-element removal in the later stage will easily cause human body damage due to incomplete treatment. Problems with micro-intake, supplementation that interfere with nutrient absorption and bodily functions in the body
