Abstract

The invention discloses a carrier biomembrane upward-filtering anaerobic purification tank with backwashing. The anaerobic purification tank is characterized by consisting of a charging pipe, a charging tank, jacking blocks, a filter plate, a backwash pipe, sponge, fine sand, a liquid through groove, a liquid outlet pipe, a biogas collection film, a biogas pipe, a liquid storage tank, a groove partition block and a biogas collection film pressing rod, wherein the filter plate is arranged on the jacking blocks, the charging pipe and the backwash pipe are arranged between the filter plate and the jacking blocks, the sponge which can uniformly distribute and raise a material liquid is arranged on the filter plate, the fine sand is arranged on the sponge, the liquid storage tank is arranged above the fine sand, the biogas collection film covers above the liquid storage tank, the pressing rod, which is coiled in place, presses the groove partition block and is immerged into the material liquid, is arranged around the biogas collection film, and the liquid through groove is formed in an outward extending part of the liquid storage tank. The anaerobic purification tank has the advantages that the material liquid with low organic substance content can be thoroughly degraded and can be discharged in a close-standard manner, and the gas yield is greatly increased under the same conditions; and the filter plate and the backwash pipe are arranged, so that blockage is not easy during long-term running.

Description

Carrier biofilm upward filtration anaerobism treating pond with back flushing

Technical field

The present invention relates to a kind of anaerobic reactor, specifically a kind of carrier biofilm upward filtration anaerobism treating pond with back flushing.

Background technology

Can adapt at present labile organic compound content lower, can react more perfect anaerobic reactor again, have baffling

Formula anaerobically fermenting device and upflowing, downflow system have carrier anaerobically fermenting device, and comparing with common methane-generating pit, they can adapt to the feed liquid fermentation that organic content is lower, raising factor of created gase.Its weak point is that baffling type anaerobic fermentation vat is not suitable with amount greatly or measures little feed variation, easily produces vicious cycle, causes and ferments unsuccessfully.Upflowing, downflow system anaerobically fermenting device easily produce and stop up, and cause fermenting unsuccessfully, and it are high to build pond cost.

Summary of the invention

The object of the invention is to provide a kind of fermentation more thorough, can adapt to organic content lower, useful volume factor of created gase is high, and capacity of resisting impact load a kind of band back flushing strong, that nothing is stopped up has carrier biofilm upward filtration anaerobically fermenting pond.

The technical scheme that realizes the object of the invention is:

A kind of carrier biofilm upward filtration anaerobism treating pond with back flushing, comprise feed-pipe, feed tank, jacking block, screen plate, backwash tube, sponge, fine sand, cross liquid ditch, drain pipe, collecting methane film, biogas pipe, liquid storage tank, ditch spacer block, collecting methane mould rod, jacking block is screen plate jack-up, the inside, space forming is provided with feed-pipe and backwash tube, on screen plate, there is sponge feed liquid can be uniformly distributed to rising, on sponge face, spread fine sand, it on fine sand, is liquid storage tank, slaking through 4 to 6 months, cause screen plate, sponge, on fine sand, can form evenly densely covered bioactive film, this bioactive film can carry out anaerobically fermenting, fermentation institute's biogas that produces enters into pneumatic tube through the collection of collecting methane film, pure feed liquid enters drain pipe by the outflow of mistake liquid ditch and outwards discharges, the surrounding of collecting methane film has pressure bar to spool to be pressed on ditch spacer block submerges in feed liquid, the every 20cm of the outward extending part of liquid storage tank left and right bank is built a spacer block and is formed feed liquid ditch.

Advantage of the present invention is: screen plate is arranged on top board, jacking block is by screen plate jack-up, and the space of formation becomes the feed tank of cross section maximum, can reduce to greatest extent the lift velocity of feed liquid, the material that density is larger a little all can deposit, and is difficult for upwards stopping up upward filtration anaerobism treating pond; The low feed liquid of organic content thoroughly can be degraded, make it approach qualified discharge, under equal conditions factor of created gase improves greatly, is provided with screen plate and back flushing long-time running and is difficult for stopping up.Through actual motion, within 6 months, show, very trickle anaerobe film is attached has around expired the fine grains of sand, has greatly increased the touch opportunity of biological bacteria fermented feed liquid, makes effectively to react bacterium and increases, and factor of created gase improves.

Accompanying drawing explanation

Fig. 1 is the structural representation with the carrier biofilm upward filtration anaerobism treating pond of back flushing.

In figure, 1 feed tank, 2 feed-pipes, 3 sponges, 4 recoil tubes, 5 fine sands, 6 screen plates, 7 are crossed liquid ditch, 8 collecting methane films, 9 drain pipes, 10 biogas pipes, 11 collecting methane mould rods, 12 liquid storage tanks, 13 ditches every fast, 14 jacking blocks.

Embodiment

With reference to Fig. 1, the carrier biofilm upward filtration anaerobism treating pond of band back flushing of the present invention, is comprised of feed tank 1, feed-pipe 2, sponge 3, recoil tube 4, fine sand 5, screen plate 6, mistake liquid ditch 7, collecting methane film 8, drain pipe 9, biogas pipe 10, collecting methane mould rod 11, liquid storage tank 12, ditch spacer block 13, jacking block 14.Feed-pipe 1 forms feed tank 1 by jacking block 14 screen plate 6 jack-up, in feed tank 1, be provided with on feed-pipe 2, recoil tube 4, screen plate 6 and be covered with sponge 3, lay fine sand 5 on sponge 3, on fine sand 5, there is liquid storage tank 12, liquid storage tank 12 stretches out, and part is built with ditch spacer block 13 banks and interval forms filtration ditch 7, collecting methane film 8 surroundings are rolled to be pressed on ditch spacer block 13 with collecting methane mould rod 11 and are submerged in the liquid of natural pond, and collecting methane film is provided with biogas pipe 10 on 8 tops.When there is operation, feed liquid enters feed tank 1 from feed-pipe 2, after whole feed tank 1 is full of, because the height of water causes pressure, feed liquid under pressure, through filter plate 6, sponge 3, fine sand 5 risings, therefore can evenly up penetrate in liquid storage tank 12, simultaneously in feed liquid the organism of low levels be attached to screen plate 6, sponge 3, biogas microorganism on fine sand 5 reacts, thereby reach the object that purifies feed liquid, the biogas producing rises voluntarily and collects via collecting methane film 8, enter in biogas pipe 10, decontaminating liquid flows out outside pond through the drain pipe 9 of liquid ditch 7, approach emission standard.

This anaerobic reaction treating pond is owing to being provided with back flushing, screen plate, sponge, fine sand, biogas microorganic adhesion in the above, although liquid passes through filtration flow, but microorganism is not taken away, form and intercept, be not flushed away, make biogas bacterial classification retain on it completely, and can carry out anaerobically fermenting to the organism in feed liquid, both formed on the one hand thorough fermentation, improve factor of created gase, formed again and resisted the powerful surging force that feed liquid produces when filtering, effective operation of support facility, so work that can be steady in a long-term, reacting phase is when thorough, the anaerobic treatment that can be widely used in the organic waste water of different concns.
