Abstract
The invention discloses a two-phase integrated anaerobic reactor. The reactor (1) consists of a hydrolysis and acidification pool (1a) and a methane producing pool (1b), wherein a flow guide plate (6) and a partition board (7) are arranged in the hydrolysis and acidification pool (1a) in a longitudinal and staggered manner to form an S-shaped water channel; the lower end of the flow guide plate (6) has a 40 to 45-degree bend; the lower part of the methane producing pool (1b) is communicated with the acidification pool (1a); and a water inlet (2) is higher than a water outlet (3). In the invention, through the integrally designed reaction, a hydrolysis and acidification phase and a methane producing phase are combined in a reactor, so the number of reactors is reduced, and floor area is reduced; the S-shaped water flow channel and the flow guide plate of which the lower end has a bend are combined to increase the mixing degree of water and sludge, so the treatment effect of the reactor is improved; and the design that the water inlet is higher than the water outlet and other design make the system hardly consume any energy.
Description
Technical field
The present invention relates to the anaerobic waste water biologic treating technique, concretely, is the incorporate anaerobic reactor of a kind of new and effective two-phase.
Background technology
Traditional diphasic anaerobic reaction process is divided into acidication and produces two processes of methane, and these two processes are independently finished in the reactor at two respectively.The acidication process is mainly the biodegradability that improves matrix, provides suitable matrix for producing methane; Producing methane and mainly be the substrate conversion that acidization provides is methane, and both constitute the diphasic anaerobic reaction process jointly.This arts demand carries out in two independent reactors, has increased capital cost and floor space, owing to increased reactor quantity, has improved the thermosteresis in operation expense and the reaction process accordingly.
Summary of the invention
The object of the present invention is to provide that a kind of floor space is few, construction costs is low, running cost is low, easy to maintenance and two-phase integral anaerobic reactor that the equipment thermosteresis is low.
For solving above technical problem, two-phase integral anaerobic reactor provided by the invention, comprise reactor (1), water-in (2), water outlet (3), gas collection mouth (4), mud discharging mouth (5), flow deflector (6) and dividing plate (7), key is: described reactor (1) by about the hydrolysis acidification pool (1a) arranged and produce methane pond (1b) formation; Described flow deflector (6) and dividing plate (7) vertically are crisscross arranged in described hydrolysis acidification pool (1a) and constitute the water stream channel (11) of S shape, described water stream channel (11) by lower one's standard or status down (11a) and on promote (11b) constitute and time lower one's standard or status (11a) than on the promote width of (11b) little; The lower end of described flow deflector (6) has 40～45 ° bending, the bottom in described product methane pond (1b) is communicated with described hydrolysis acidification pool (1a), the middle part in this product methane pond (1b) is provided with filler (8), and described water-in (2) is higher than described water outlet (3).
As preferably, the distance of described flow deflector (6) lower end and described hydrolysis acidification pool (1a) bottom is 2 ± 0.5 cm, described lower one's standard or status down (11a) with on the promote ratio of width of (11b) be 1:1.5, be that acid-producing bacteria is created growing environment preferably.
The bottom in described product methane pond (1b) is flat, and the middle part of producing methane pond (1b) is provided with filler (8); Described product methane pond (1b) is positioned at the lower left quarter that produces methane pond (1b) with the connected entrance (13) of hydrolysis acidification pool (1a), and described mud discharging mouth (5) is arranged on the right lower quadrant that produces methane pond (1b), and described connected entrance (13) is than mud discharging mouth (5) height; Be horizontally arranged with drainage plate (9) in the top of described connected entrance (13), between described connected entrance (13) and mud discharging mouth (5), be provided with the mud guiding plate (14) of inclination.Produce the methane pond and be set to flatly, help putting of reactor; Mud guiding plate is obliquely installed, and helps mud and discharges along the scarp precipitation of mud guiding plate and through mud discharging mouth, avoids forming the dead angle.
All have thief hole (10) on the sidewall in described hydrolysis acidification pool (1a) and product methane pond (1b), thief hole is set, be convenient to test sheet and detection.
Anaerobic biological treatment is divided into acidication and produces two stages of methane, the present invention is by the reactor of integrated design, acidication with produce methane and be combined in the reactor and finish, so can make the left part of reactor and the optimum growh environment that right part satisfies acid-producing bacteria and methanogen respectively, in a reactor, realize producing acid phase and effective separation of producing the methane phase.Acidification pool is the product acid section of baffling type anaerobic reactor, produces the rising sludge bed reactor of methane pond for the band filler.Sewage enters acidification pool from water-in, enter product methane pond from the bottom of producing the methane pond through the pretreated matrix of acidification pool, mud is discharged along the scarp precipitation of mud guiding plate and through mud discharging mouth, discharge from the gas collection mouth through the methane gas that produces after the methane pond transforms, the water after handling is then discharged from water outlet.Filler is used for attached microbial, forms microbial film, reduces the loss of reactor microorganism, strengthens the quality of water outlet.
Beneficial effect of the present invention:
1) place same reactor to finish acid-producing bacteria and methanogen, reduced reactor quantity, solved traditional diphasic anaerobic technique owing to the construction of adopting two separate reactors to cause and working cost height, problem that floor space is big, thereby whole construction costs and maintenance cost are obviously reduced.
2) utilize the principle of communicating vessels, and water-in is higher than water outlet, do not need to be provided with pump, total system is not consumed energy substantially;
3) by in hydrolysis acidification pool, vertically being arranged alternately the water stream channel that flow deflector and dividing plate constitute S shape, and lower one's standard or status down than on the width of promoting little, current are increased at bottom stream, avoided sludge settling, improve the mass transfer effect between mud and the water, improve reaction efficiency;
4) very little slit is left in flow deflector lower end and hydrolysis acidification pool bottom, and current will increase herein greatly, thereby the generation that has prevented excess sludge improves the interior biomass of reactor.
