Abstract

The utility model relates to a pressure film filtering drainage anaerobic reactor, the shell body of which is a sealing pressure bearing type tank structure; certain internal pressure is generated in the reactor under the action of intake pressure; a film filtering drainage device is arranged in the reactor; under the action of the internal pressure, sewage which takes the biochemistry action is drained by the film filtering drainage device, and anaerobic sludge in the water is blocked in the reactor to greatly enhance the sludge concentration in the reactor, and thus, biochemistry efficiency is greatly enhanced. The utility model can be used as a hydrolysis acidification reactor used for producing acid phases through adjusting design parameters, and can be used as an anaerobic reactor used for producing methane phases. The utility model has the advantages of small equipment volume, simple structure, high processing efficiency, good water draining quality, convenient operation management, low construction cost, etc.

Description

Anaerobic reactor with filtering and draining pressurized film

The present invention is a sewage disposal technology.

Anaerobic Microbiological Treatment Technology is owing to have distinguishing features such as operation energy consumption is low, sludge yield is few, organic loading height, used widely in handling high-concentration organic industrial waste water and develops.Existing various anaerobic biological treatment methods are more, but there is a common shortcoming, a large amount of anaerobic sludges are difficult to all be retained in the reactor in the water, considerable part mud runs off with water outlet the sludge concentration in the reactor is reduced, have a strong impact on the biochemical reaction efficient and the effluent quality of anaerobic reactor, cause that the anaerobic reaction equipment volume is big, cost is high.

In view of the existing above-mentioned many disadvantages of existing anaerobic biological treatment method, the objective of the invention is to invent a kind of anaerobic reactor with filtering and draining pressurized film, utilize the micro-pore-film filtration filtration of material, all be retained in the anaerobic sludge in the water outlet in the reactor, increased the sludge concentration in the reactor effectively, biochemical efficiency is greatly improved, thereby reaches the purpose that effluent quality is good, equipment volume is little, construction costs is low.

According to design, the housing of anaerobic reactor with filtering and draining pressurized film of the present invention is a seal and pressure bearing formula tank structure, presses in the generation necessarily in the reactor under the intake pressure effect.In reactor, be provided with the membrane filtering drainage device, biochemical good sewage is under interior pressure effect, after filtering, the membrane filtration module on the membrane filtering drainage device discharges, the mud that suspends in the water then all is retained in the reactor, anaerobic sludge concentration in the reactor is increased substantially, thereby sewage treating efficiency also is greatly improved thereupon.

In order to further specify implementation detail of the present invention, provide most preferred embodiment of the present invention below in conjunction with accompanying drawing.

Accompanying drawing 1 is an anaerobic reactor with filtering and draining pressurized film.

Accompanying drawing 2 is the membrane module structural map of membrane filtering drainage device.

Shown in accompanying drawing 1, accompanying drawing 2, the housing 1 of anaerobic reactor with filtering and draining pressurized film of the present invention is a seal and pressure bearing formula tank structure, and safety valve 2, electric-powered air release valve 3, pressure transmitter 4, water inlet pipe 5, shore pipe 6 are installed thereon.In reactor, be provided with into water injector 10, membrane filtering drainage device 9, water level sensor 7, water level sensor 8.Many groups membrane filtration module 11 that membrane filtering drainage device 9 is made by the micro-pore-film filtration material is fixed in that ring-type is catchmented the membrane filtering drainage system that constitutes on the water shoot 12 and the automatic backwash system of the membrane filtration module 11 that is made of backwashing pump 13, electrically operated valve 14, electrically operated valve 15, pressure transmitter 4 and housing 16 forms.Wherein membrane filtration module 11 is membrane filtration bags 17 made from the micro-pore-film filtration material, be placed in percentage of open area greater than also using lock ring 19 that its sealing and fixing is formed on 50% the tubular support frame 18, the top of membrane filtration module 11 is union 20, is used for that membrane filtration module 11 is fixed in ring-type and catchments on the water shoot 12.

Implement the present invention, sewage is advanced in people's reactor by water inlet injector 10 by water inlet pipe 5, and under the mixing and stirring action of injector 10, very fast being diffused into equably in the reactor with behind the mud thorough mixing carried out biochemical reaction.Under the intake pressure effect, form certain interior pressure in the reactor, under interior pressure effect, biochemical good sewage is discharged after the membrane filtration module on the membrane filtering drainage device 9 11 filters, the mud that suspends in the water then all is retained in the reactor, sludge concentration in the reactor is improved significantly, and biochemical efficiency also is improved thereupon significantly.After operation for some time; it is more and more to be adsorbed in membrane filtration bag 17 lip-deep mud flco things; the membrane flux of membrane filtration bag 17 is progressively reduced; water displacement reduces; press constantly in the reactor and increase; in case reach the design pressure value; then pressure transmitter 4 arrives housing 16 with message feedback at once; 16 instructions of housing intake pump is shut down, and closes electrically operated valve 15, opens electrically operated valve 14; start 13 pairs of membrane filtration bags of backwashing pump 17 and carry out back flushing; its membrane flux is recovered, and under housing 16 instructions, membrane filtering drainage device 9 recovers works better afterwards.Owing to can produce a large amount of gases in the anaerobic reaction process, occupy big quantity space and make water level decline in the reactor, in case liquid level drops to barrier line, water level sensor 7 had both been carved message feedback to housing 16, housing 16 had both been carved and had been opened electric-powered air release valve 3, the liquid level that water inlet is risen is all discharged gas in the reactor, after treating that liquid level rises to set(ting)value, water level sensor 8 had both been carved and had been given housing 16 with message feedback, housing 16 is closed electric-powered air release valve door 3 at once, makes reactor recover normal operating conditions.In case some fault that occurs in service causes pressing above set(ting)value in the reactor, then safety valve 2 is opened interior pressure and the warning that sheds reactor automatically, can carry out shutdown maintenance to total system.

The present invention can make it both can be anti-as the anaerobism of producing sour phase by adjust design parameters Answer both reactor for hydrolysis and acidification of device, can use as the anaerobic reactor of methanogenic phase again, Compare with other anaerobic bio-treated method, the present invention has little, the structure letter of equipment volume Single, treatment effeciency is high, effluent quality good, operational management is easy, it is many that construction costs is low etc. Advantage.
