Abstract
The utility model relates to a high-concentration waste water anaerobic treatment apparatus, which comprises a first reaction chamber, a second reaction chamber and a methane-liquid separator, the inner top of the first reaction chamber is provided with a methane riser which is connected into the methane-liquid separator, the inner top of the second reaction chamber is provided with a methane-collecting tube which is connected into the methane-liquid separator, and meanwhile, a return pipe is led out of the methane-liquid separator and extended into the first reaction chamber. The innovation of the utility model is as follows: the methane riser and the return pipe are added in the first reaction chamber, and the methane-liquid separator is added on the top. In the process of operation, the methane produced by the first reaction chamber is collected by methane-collecting hoods and rises along the riser to serve as power, which rises the fermentation liquor and sludge of the first reaction chamber to the methane-liquid separator on the top of the reactor, the separated methane is exhausted via a conduit, sludge-water mixture returns into the first reaction chamber via the return pipe, and thereby the lower liquor is internally circulated. When low-concentrated waste water is treated, the circulating flow can be up to 2 to 3 times as high as the influent water flow, and when high-concentration waste water is treated, the circulating flow can be up to 10 to 20 times as high as the influent water flow.
Description
Technical field
The utility model relates to a kind of high-concentration waste water anaerobic processing device.
Background technology
Waste water treatment engineering selects for use anaerobic treatment to adopt internal-circulation anaerobic reactor, is called for short QIC.It is the present the highest anaerobic reactor of usefulness in the world.The QIC anaerobic reactor is my company continuous perfect best anaerobic treatment technology in practice for many years.Now successful adopts QIC anaerobic treatment technology in Anhui Hua Mao limited-liability company, Anhui Hua Tai Fabritex S.r.l., Anhui blast furnace wine brewing company limited, Bozhou Gu Jing alcohol company limited, Woyang blast furnace wine brewing company limited, the inferior strong natural pigment company limited in Bozhou, the wide wood industry in Hefei company limited, food limited liability company of Hefei Cathay etc., treatment effect is stable good, the factor of created gase height is subjected to local environmental administration and user's favorable comment.This reactor is the advantage that integrates UASB reactor and fluidized reactor, utilizes a kind of novel reactor of the lifting force realization fermented feed liquid internal recycle of the biogas that produces in the reactor.
The utility model content
The purpose of this utility model provides a kind of high-concentration waste water anaerobic processing device, is a kind of novel reaction container that utilizes the lifting force realization fermented feed liquid internal recycle of the biogas that produces in the reactor.
For realizing above purpose, scheme of the present utility model is:
A kind of high-concentration waste water anaerobic processing device, comprise first reaction chamber, second reaction chamber and gas-liquid separator, second reaction chamber is positioned at the top of first reaction chamber, and be communicated with between two reaction chambers, the top of two reaction chambers is respectively equipped with sealing gland, described sealing gland is installed on the inwall of two reaction chambers ringwise; The top of first reaction chamber and second reaction chamber is respectively equipped with the gas skirt of taper, the first reaction chamber inner top is provided with the biogas-lift pipe coupling to gas-liquid separator inside, the second reaction chamber inner top is provided with effuser and is connected to gas-liquid separator inside, draws return line to the first a reaction chamber inside simultaneously in gas-liquid separator inside; The top of second reaction chamber is the settling region, and rising pipe is drawn at the top of settling region; Bottom water-in water inlet by first reaction chamber; Top at gas-liquid separator connects the biogas conduit.
Innovation part of the present utility model is, set up biogas-lift pipe and return line in the first reaction chamber inside, and top has increased gas-liquid separator.During this reactor start-up, a large amount of granule sludges have been added.In the operational process, rise as power through the gas skirt collection and along riser tube with first biogas that reaction chamber produces, the fermented liquid of first reaction chamber and mud are promoted to the gas-liquid separator of reactor head, isolated biogas is drained from conduit, muddy water mixed solution returns in first reaction chamber along return line, thereby has realized the internal recycle of bottom feed liquid.As circular flow can reach 2～3 times of flooding velocity when handling low concentration wastewater, and circular flow can reach 10～20 times of flooding velocity when handling high-concentration waste water.The result makes the first anaerobic reaction chamber that very high biomass not only be arranged, very long mud residence time, and very big up-flow speed is arranged, make the mud of this reaction chamber and feed liquid be in complete admixture substantially, thereby improve the removal ability of first reaction chamber greatly.Through the waste water that first reaction chamber was handled, enter the second anaerobic reaction chamber automatically.Residual organic substances in the waste water can further be degraded by the granule sludge of second reaction chamber, and waste water is better purified.Waste water through bi-level treatment carries out solid-liquid separation in the mixed solution settling region, and clear liquid is discharged by rising pipe, and sedimentary granule sludge can return second reaction chamber automatically.Waste water has been finished whole treating processess like this.
