Abstract
The utility model discloses a novel pulse water-distribution UASB water treatment device and relates to the technology of waste water treatment equipment. In order to solve the problems of non-uniform water distribution, blocking, short flow and the like that are easy to occur in a UASB reactor, the utility model proposes the improved device, wherein uniform water distribution can be realized by adopting the combination of a pulse water distributor and a novel water distribution device, so as to promote the mixing of mud and water in the reactor; the novel water distribution device comprises a water distribution bracket and water distribution plates that are arranged compactly, and water passes through the gaps between the water distribution plates and baffles into the reactor; and a backflow baffle plate is arranged in air chamber of a three-phase separator, thereby being helpful for the backflow of the mixed liquor in the air chamber, preventing the blocking and being beneficial for release and collection of air. The novel pulse water-distribution UASB water treatment device has small investment and high water treatment efficiency, can effectively recover the methane resource and also has the advantages of stable running, convenient operation and management and the like.
Description
Technical field
The utility model relates to a kind of sewage treatment equipment, specifically is water treatment method and the device of a kind of pulse water distribution UASB.
Background technology
Anaerobic biological treatment is utilized the metabolism of anerobe, need not provide under the condition of external source energy, to be reduced organism as hydrogen acceptor, produces the methane gas that has the energy to be worth simultaneously.Be not only applicable to high concentrated organic wastewater, water inlet BOD maximum concentration can reach tens thousand of milligrams per liters, also applicable to low-concentration organic waste water, as municipal effluent etc.Advocate recycling economy in the whole society, pay close attention to today that trade waste is implemented resource recycling, anaerobic biological treatment obviously is the selection process that can make sewage recycling.Filter and the dual characteristics of anaerobic activated sludge method by anaerobism owing to having for upflow anaerobic sludge blanket process (UASB) technology, as pollutants in sewage being changed into the regeneration clean energy---and a technology of biogas.Adaptability for different solid content sewage is also strong, and its structure, operation maintenance management are simple relatively, and cost is also relatively low, is subjected to the attention of sewage disposal industry just day by day, is welcome widely and uses.
Yet UASB still exists some problems in actual moving process.Flow-shape in the UASB is comparatively complicated, because the result of aerogenesis, form the air-flow of one rising in the reactor, driving the part muddy water mixed solution moves upward, meanwhile, the medium around this strand gas, the current then moves downward, and causes backmixing, this fluidised form has caused the short stream of water, then forms the dead angle easily in the place away from this burst rising gas, current.Thereby the steady running of UASB system need be provided with rational water inlet and water distribution manner, and problems such as the inhomogeneous and obstruction of water distribution appear in UASB easily in the actual engineering.
The utility model content
The purpose of this utility model is the defective at traditional UASB reactor, a kind of novel pulse water distribution UASB water treatment method and device are proposed, this utility model adopts the pulse water distribution device that pulse water-feeding is provided, and adopt novel water distribution device to match with it, uniform pulse current are provided for reactor on the one hand, intermittence provides ascending current and mud setting time, promotes muddy water to mix, and has solved the water distribution blocking problem on the other hand; And the air chamber at triphase separator is provided with reverse-flow baffle, promotes the air chamber mixed-liquor return, prevents to stop up, and is beneficial to gas release and collection.
The utility model is realized by following scheme: this device comprises pulse water distribution device 1, novel water distribution device 2, UASB reactor 3 and triphase separator 4; It is characterized in that this triphase separator 4 is provided with the air chamber reverse-flow baffle, this novel water distribution device 2 is made up of water distribution carriage 9 and compact arranged water distribution board 10, and this water distribution board 10 tilts to be positioned on the water distribution carriage 9, constitutes the cloth hydroecium with water distribution carriage 9; Current enter in the reactor by the slit baffling between the water distribution board 10; Novel water distribution device 2 is circular, square or rectangle, contains two groups or more water distribution board, and water distribution board ringwise, back-shaped or linear pattern arranges.
A kind of novel pulse water distribution UASB water treatment method that adopts said apparatus is characterized in that, water inlet provides the pulse current by pulse water distribution device 1, enters in the reactor through novel water distribution device 2; The special design of novel water distribution device 2 makes the sludge blanket 5 abundant contact reactss in current and the reactor and can effectively prevent blockage problem; The bubble that muddy water reaction back produces carries the sewage mixture and enters triphase separator through suspended layer 6, scatters when bubble is run into reverse-flow baffle, enters air chamber 7, derives through the conduit at air chamber 7 tops; Sewage mixed solution in the air chamber 7 is back to suspended layer 6 through the reverse-flow baffle of triphase separator 4; Mud in the sewage flocculates mutually and accumulates under the action of gravity; The sewage mixed solution enters settling region 8 precipitated outlet water; This method provides the pulse water-feeding mode by the pulse water distribution device, for reactor provides step ascending current and mud setting time, promotes muddy water to mix; Novel water distribution device can effectively prevent blockage problem when even water inlet is provided; The cloth hydroecium provides condition for the uniform distribution of water inlet; Triphase separator is provided with the air chamber reverse-flow baffle, the mud that accumulates in air chamber can be back to suspended layer, prevents that air chamber from stopping up, and is beneficial to gas release and collection.
The utility model has overcome short stream and the dead angle phenomenon in traditional UASB reactor, the method that adopts pulse water-feeding mode and novel water distribution device to combine provides water distribution uniformity, promote that muddy water mixes in the reactor, the reverse-flow baffle of triphase separator helps the air chamber mixed-liquor return, prevent to stop up, be beneficial to gas release and collection.The utility model less investment, water treatment efficiency height, but efficient recovery biogas resource also have stablely, are convenient to advantages such as operational administrative.
