Background technology
The removal of nitrogen and phosphorus has caused people's extensive concern in the sewage, and denitrogenation dephosphorizing research has great significance to water environment protection.Wastewater treatment in China factory denitrification dephosphorization technique ubiquity the energy consumption height at present, efficient is low and the shortcoming of fluctuation of service.To this present situation, research is fit to China's national situation and cost-effective denitrification dephosphorization technique and method, particularly develops the COD oxidation with minimum, minimum CO
2Release, minimum excess sludge production, the recovery of phosphorus and the sustainable sewage disposal technology that the treating water reuse is target become imperative.
BAF is a kind of novel sewage disposal technology that grows up the America and Europe late 1980s; Have that processing efficiency height, floor space are little, capital construction and characteristics such as working cost is low, convenient management and capacity of resisting impact load are strong, at the organic matter removal of sewage, nitrated deammoniation, denitrification denitrogenation application promise in clinical practice is arranged.
The phosphor in sewage nutrition content increases, and be disposed to natural water after the WWT and still contain a large amount of phosphorus, be the major cause that causes eutrophication.Can know from present research; BAF is owing to lack necessary alternately anaerobism one aerobic condition of biological phosphate-eliminating; It has been generally acknowledged that the single-stage BAF only depends on biological assimilation and physical filtering dephosphorization efficiency by using to be everlasting about 20% under the conventional operation condition, reach as high as 35%.The dephosphorization efficiency by using of single-stage BAF is the technical barrier of its practical applications of puzzlement always.This patent has improved the effect of BAF denitrogenation dephosphorizing effectively with chemical precipitation and being integral of BAF organic assembling denitrogenation dephosphorizing reactor drum.
Summary of the invention
The utility model purpose is to solve the low problem of dephosphorization efficiency by using that above-mentioned BAF exists, and a kind of integration denitrification and dephosphorization square BAF reactor drum is provided.Reactor drum comprises equalizing tank (1); Equalizing tank is connected with vertical sedimentation basin (5) through Sewage metering pump (2); On the pipeline section that connects Sewage metering pump (2) and vertical sedimentation basin (5), tubular static mixer (4) is installed; Vertical sedimentation basin (5) bottom is connected to shore pipe (19), and the water outlet overflow of vertical sedimentation basin top gets into square BAF (6), and aeration plate (12), aeration tube (11), back flushing water inlet pipe (15), rising pipe (9) are installed in square BAF (6) bottom; Air (10) is connected with aeration tube (11); Backwash pump (14) is connected with back flushing water inlet pipe (15), and vertical sedimentation basin (5) places square BAF (6) inside, and square BAF (6) inner stuffing is a lime carbonate type biofilter material.
For addressing the above problem, the utility model comprises coagulation device, vertical sedimentation basin and square BAF.Coagulation device adopts tubular static mixer, is located on the former water water inlet pipe, is used for adding of coagulating agent.Vertical sedimentation basin top is that settling region, bottom are the mud district, is buffer zone between two districts, and water gets in the pond from pipe core from top to bottom, and the umbellate form baffle plate is established in the exit, makes water uniform distribution in the pond, and the bottom is connected to shore pipe.The top water outlet of vertical sedimentation basin gets into the square BAF through overflow all around, and the filter tank comprises supporting layer, packing area, air distribution and water distribution district and aerating apparatus.Aerating apparatus places the air distribution and water distribution district, and the air distribution and water distribution district is connected to aeration plate, rising pipe, back flushing water inlet pipe.
Described coagulation device is a tubular static mixer, simple in structure, advantages of small volume, do not need special occupied ground, install easily, less investment, long service life, mixing efficiency be high, reach moment to mix the purpose of saving the energy.
The water inlet of deposition part is that through the deposition part, SS content significantly reduces in the former water by the mixing liquid of sump pump pressurization through coagulation device, for follow-up square BAF provides best influent quality parameter, and gets rid of most of phosphorus in the water.
There are filtrating area and exhalant region in described biological filter; The built-in lime carbonate type of filtrating area biofilter material, the bottom supporting layer is a pebbles, the bottom links to each other with exhalant region through the porous supporting plate; Water after the precipitation process gets into the filter tank via overflow around the vertical sedimentation basin top; Even for aeration, be provided with aeration plate in the exhalant region, be connected with air through aeration tube.The distribution district of the exhalant region of bottom during as aeration, the water distributing area during also as back flushing, backwash tube links to each other with backwash water through the backwash pump pressurization.
The vertical sedimentation basin outer wall is a square, and BAF is built in its outside for square, and the outer wall of vertical sedimentation basin is as the inwall in filter tank, UNICOM not mutually, and vertical sedimentation basin water is by top overflow to filter tank, and the operation in two ponds is not disturbed mutually, and is stable.
The utility model compact construction, modular construction are convenient to the later stage reorganization and expansion, and equipment production, can be used for the less factory and enterprise of sewage quantity.Chemical precipitation dephosphorization, physics through to sewage is held back, is reached bio-oxidation and handles, and reaches the purpose of sewage purification, helps to protect environment, economizes on resources.
