Description
Technical field
The invention belongs to technical field of waste water processing, specifically just relate to a kind ofly can improve the homogeneity of water distribution, avoid the hybrid anaerobic sludge filter bed of internal duct fouling.
Background technology
Along with the raising of people's living standard; produce and live and create a large amount of waste water; water is Nonrenewable resources; although the area of earth surface 70% is awash; but the Freshwater resources that really can be total to mankind's use are but very limited; it is reported; all there is " water crisis " in the whole world now a lot of place; in fact; the mankind are not real lacks of water, and just lacking can the water resources of health that uses of the mankind, especially the waste water that produces of industrial production; owing to wherein usually containing heavy metal and other organism, direct discharge also can cause substantial pollution.Therefore, aftertreatment is carried out to the waste water that industry produces, avoids it to the pollution of environment, and waste water is re-used saving water resource.
Over nearly 20 years, along with the development of the subject such as microbiology, biological chemistry and the accumulation of engineering experience.The various anaerobic treatment process for wastewater treatment waits until widespread use, Anaerobic wastewater treatment is the one of biological effluent treatment, be utilize anaerobion with the organic pollutant in degrading waste water, it mainly contains up-flow anaerobic sludge blanket, anaerobic filter and up-flow anaerobic sludge blanket filter tank.
As shown in Figure 1, the main part of rising streaming anaerobic mud bed reactor is mainly divided into two regions, i.e. reaction zone and three-phase separation area, wherein reaction zone is the operative body of reactor, there is following problem at present: first, the easy fouling of internal duct or blocking, containing total hardness in waste water, basicity, sulfate radical, these ions can form the material of difficult degradation, water inlet adopts pipeline water distribution, easily irreversible fouling is formed in piping system, be difficult to remove, the effluent recycling of anaerobic filter is to dilute the concentration of each material in former water simultaneously, in recycling effluent, the same partial sludge that contains can cause water distributor dirt stifled, secondly, water distribution is uneven, and water distribution pipe blocking causes follow-up water distribution uneven, 3rd, it is more serious that mud is run in water outlet.Do not arrange filler, cause sludge loading relatively little, race mud phenomenon is serious.
As shown in Figure 2, anaerobic biofilter is researched and developed in 1967 by Young and Mc.Carty of Standford university of the U.S. on the basis of biological filter, is generally acknowledged early stage efficient anaerobe reactor.Anaerobic biofilter is the anaerobic biological reactor that a kind of inside is filled with microbe carrier (i.e. filtrate).There is also line clogging and the uneven shortcoming of water distribution.
As shown in Figure 3, upflow sludge blanket filter tank comes across the mid-50 in last century the earliest.There is first combined upflow sludge blanket filter tank reactor in the mid-80.It incorporates the technological merit of up-flow anaerobic sludge blanket and anaerobic filter: top filter bed being placed in Sludge Bed, is intake by bottom, and in top water outlet and gas collection, working efficiency is higher, but still there is line clogging and the uneven shortcoming of water distribution.
Summary of the invention
Water distribution is there is uneven for existing traditional anaerobic filter, pipeline holds susceptible to plugging technological deficiency, hybrid anaerobic sludge filter bed provided by the invention, traditional water technology is improved, improve the homogeneity of water distribution, avoid internal duct fouling, alleviate the difficult problem that mud is run in water outlet, whole apparatus structure is simple, and installation and maintenance are convenient.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of hybrid anaerobic sludge filter bed, it comprises anaerobic reactor body 1, it is characterized in that: described anaerobic reactor body arranges vertical shaft, vertical shaft communicates with the external world, be positioned at anaerobic reactor body bottom portion below vertical shaft and stirrer is installed, be positioned in anaerobic reactor chamber body above stirrer and be provided with filler portion, anaerobic reactor body is positioned at stirrer top position below filler portion and has intake, intake is connected with circulation water diversion tank, circulation water diversion tank output terminal is connected with anaerobism recycle pump, anaerobism circulation delivery side of pump is connected with steam heater, the output terminal of steam heater connects back vertical shaft opening part, the loop that steam heater connects back vertical shaft opening part is provided with temperature sensor.
Described anaerobic reactor body bottom portion is provided with anaerobic sludge responding layer.
Described intake is positioned at more than anaerobic reactor body lower surface 1/3 ~ 1/2 place.
