This kind of up -flow anaerobic sludge blanket filtering pond's treatment effect is better.
Description
Technical field
The utility model relates to a kind of water-treatment technology field, particularly relates to a kind of up-flow anaerobic sludge blanket filter tank.
Background technology
High concentrated organic wastewater is the one of waste water, and it mainly appears at the fields such as food, papermaking, livestock industry, percolate, pharmacy, chemical industry.Generally first use anaerobic treatment for this type of waste water, its anaerobic treatment, compared with Aerobic biological process technology, has the advantage that energy consumption is little, load is high, can also produce available Methane Resources simultaneously.The device of existing techniques in realizing and up-flow anaerobic sludge blanket filter tank (Up-flowBlanketFilter, UBF) same function also has upflow anaerobic sludge blanket reactor (UASB), IC reactor and EGSB anaerobic reactor etc.UASB and EGSB system is in operation, and needs to arrange triphase separator, complex structure.The deflation that the triphase separator system of UASB is given runs mud phenomenon obviously, and is separated thorough, and EGSB is highly higher, and along with the rising of height, the kinetic energy of methane accumulation is more and more higher, causes the kinetic energy of exhalant region high, causes anaerobic sludge to be easily with gas to float.IC reactor adapts to high upflow velocity condition, and it is serious that debugging initial stage floc sludge runs mud, and debugging cycle is long, and quantity of circulating water is large simultaneously, and energy consumption is high.Up-flow anaerobic sludge blanket filter tank (UBF) replaces triphase separator with filler, easy construction, adopts filler biofilm can also increase volumetric loading simultaneously, improves organic processing efficiency.Conventional up-flow anaerobic sludge blanket filter tank (Up-flowBlanketFilter, UBF) tank body of a hollow is comprised, water distribution layer, mud bed, packing layer and clear layer from the bottom up successively in described tank body, main principle of work is, first high concentrated organic wastewater enters into water distribution layer by pipeline and is uniformly distributed, then through mud bed laggard enter to packing layer, microbes in high concentrated organic wastewater is attached to growth in packing layer, because high concentrated organic wastewater directly contacts with packing layer after mud bed, just enter into clear layer
So the microorganism in high concentrated organic wastewater can not well adapt to, can not good apposition growth on packing layer, can not effectively utilize the pond of original UBF to hold simultaneously, improve digestion effect, extend the sludge retention time in UBF reactor, improve reactor to the adaptability of undesirable element.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind for the treatment of effect good up-flow anaerobic sludge blanket filter tank.
The technical scheme that the utility model adopts is: a kind of up-flow anaerobic sludge blanket filter tank, comprise the tank body of hollow, described tank body is provided with water distribution layer, the first mud bed, the first packing layer and clear layer from top to bottom successively, described tank body is also provided with suction culvert, described suction culvert is communicated with water distribution layer, is also provided with the second packing layer and the second mud bed between described first mud bed and the first packing layer.
Adopt above structure compared with prior art, the utility model has the following advantages: arrange two packing layers, the hydraulic shear of Sludge Surface in high concentrated organic wastewater can be increased like this, be conducive to the granulating of anaerobic sludge, shorten the operation start time in up-flow anaerobic sludge blanket filter tank, make microorganism in mud can Adaptable growth faster, improve the operation treatment effect in up-flow anaerobic sludge blanket filter tank; Two packing layers are set also for better for microorganism provides carrier simultaneously, improve the quantity of microorganism, and the pond that make use of reaction filter tank fully hold, and makes the treatment effect in up-flow anaerobic sludge blanket filter tank better.
As preferably, in described second packing layer, be provided with the spherical granule filter material that suspends.The spherical granule filter material that suspends is set in the packing layer of bottom second; the hydraulic shear of Sludge Surface can be increased like this; be conducive to the granulating of anaerobic sludge, shorten the operation start time in up-flow anaerobic sludge blanket filter tank, improve the operation treatment effect in up-flow anaerobic sludge blanket filter tank.
As preferably, described suction culvert comprises many water inlet pipes, and multiple water inlet pipe is communicated with the water distribution layer of tank base through tank body top.Such setting not only water distribution is relatively more even, and can be convenient for changing water inlet pipe when water inlet pipe dirt is stifled.
As preferably, described tank body top is provided with the separate layer for gas and liquid being isolated, and described separate layer top is provided with waste gas outlet, and is provided with in described separate layer for preventing foam by the spray equipment of waste gas outlet.Such setting can well separate gas and liquid, and can prevent foam from passing through waste gas outlet.
