Description
Technical field
The utility model relates to water treatment field, and concrete is a kind of novel hydrolysis acidification device.
Background technology
Hydrolysis acidification pool can be micromolecular material with macromolecular Substance Transformation in the waste water, ring texture is converted into chain-like structure, long-chain is hydrolyzed to short chain, side chain becomes straight chain etc., and then the ratio of raising BOD/COD, increase the biodegradability of waste water, for good environment is created in follow-up further biochemical treatment.Acidication art breading trade effluent is divided into hydrolysis and two stages of acidifying, as long as adapt to the microorganism species generation of hydrolysis-acidifying, just can make that the material of difficult degradation obtains degrading in the waste water.Its main microorganism is hydrolysis bacterium and acid-producing bacteria, and they are facultative bacteria, utilize hydrolysis bacterium and acid-producing bacteria, is small organic molecule with the organic matter degradation of macromole, difficult degradation, improves the biodegradability of waste water, for subsequent disposal creates favorable conditions.
Hydrolysis stage be larger molecular organics degraded must be through process, larger molecular organics is wanted to be utilized by Institute of Micro-biology, must be hydrolyzed to first small organic molecule, so just can enter further degraded in the bacterial cell.Souring stage is the speed-raising process of organic matter degradation, because its small organic molecule after will being hydrolyzed is further converted to simple compound and is secreted into the extracellular.Therefore, the pretreatment unit often processed as wastewater biochemical of acidication.
Hydrolysis acidification pool is widely used in the processing of pharmacy, food, printing and dyeing, chemical industry, papermaking and municipal wastewater etc., adopt single active sludge to process yet common hydrolysis acidification pool is most, not with active sludge and the effective combination of microbial film, and the water intake mode that adopts is pressure current water distribution or run by gravity pulse water distribution system.Single activated sludge process will certainly cause in the pond active mud content not high, the shortcoming such as organic loading is low, and surplus sludge volume is large.The pressure current water distribution is adopted dendritic or ring-type perforation water distribution mode, and the water distribution of boring a hole on the one hand easily causes the aperture to stop up and be difficult in time find and cause water distribution uneven; On the other hand because water-distributing device is difficult to safeguard that long-play causes producing the dead band descends the reactor useful volume at the bottom of being submerged in the pond.Run by gravity pulse water distribution system exists brings that air enters the defective of reaction zone into and the reaction efficiency that reduces anaerobic fixed film reactor.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is that A-A among Fig. 1 is to sectional view.
Fig. 3 is that B-B among Fig. 2 is to sectional view.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 to Fig. 3, the hydrolysis acidification device of this Creative Design on the basis of existing installation, has increased water-distributing device and hydrolysis filling device.
Described water-distributing device comprises that water inlet pipe 12, the cloth supply mains 5 who is connected with this water inlet pipe and this cloth supply mains arranged transversely, two water distribution supervisors 1 that are connected with the cloth supply mains are responsible for the water distributor 3 that is connected with the center with this water distribution, evenly be provided with many water distribution branch pipes 2 on the water distributor, the upper end of every water distribution branch pipe is provided with V-type crest of weir 4, and its lower end is about 1m with the water distribution head 8(cloth water area that is distributed at the bottom of the hydrolysis acidification pool pond
2) connect.Wherein, water distribution head becomes arranged at the bottom of the pond, and the distance between it is horizontal, vertical is about 1000mm.
During use, waste water enters hydrolysis acidification pool by water inlet pipe 12, branches to two water distributions supervisor 1 by cloth supply mains 5, flowing to many water distribution branch pipes 2 by the water distribution supervisor again, water distribution branch pipe 2 by water distribution head to the hydrolysis acidification pool water distribution uniformity.Water distribution system not only can guarantor unit's area flooding quantity basic identical, thereby effectively avoid dead band and the short circuit phenomenon of the inhomogeneous generation of water distribution, and water distribution uniformity can satisfy the needs of hydraulic mixing, need not use stirrer, saves energy consumption and working cost.
The hydrolysis filling device comprises that hydrolysis filling 9(enzyme floats filler, it is characterized in that the surface band positive charge, easily make microorganism adhere at carrier surface, fix, greatly increase the total amount of microorganism) and filler support 10, hydrolysis filling 9 supports by top and bottom support 10 and is fixing.The setting angle of described hydrolysis filling 9 in the pond becomes 60 ° of angles with horizontal plane at the bottom of the pond, mounting height is about 1/3～2/5 of hydrolysis acidification pool available depth, installing space 200mm.
During use, waste water is certain residence time of process in the pond, microorganism at the bottom of the pond on the anaerobic activated sludge flows out to next structures processing unit with the organism that adsorbs in the microbial film oxygenolysis waste water that is trapped on the hydrolysis filling 9, its water outlet through rectangular weir 11.Be not difficult to find out that enzyme swims to separate the adding of filler, realized " duplicature " of filler and the special construction of " void layer ", specific surface area is large, and porosity is high, and after testing, specific surface area is greater than 1000 m
2/ m
3, porosity reaches 0.98, all significantly surpasses the performance of similar filler.Behind the floating filler process ionized material modification of enzyme and the hydrophilic high mol blending and modifying, the surface band positive charge, this will make microorganism adhere at carrier surface, fix, and greatly increase the total amount of microorganism.
In sum, improving technological design keys mainly is two aspects: the one, and design hydrolysis uniformity of water distribution.The water distribution of hydrolysis adopts point-to-point water distributor, to reach uniformity of water distribution, improves the efficient of hydrolysis.The 2nd, for the sludge quantity that keeps hydrolysis acidification pool and the efficient that further improves hydrolysis, set up high efficiency packing.The relatively traditional acidication technique of novel hydrolysis acidification technique can improve COD, BOD in the waste water
5Removal effect, improve BOD
5The value of/COD improves condition and the efficient of follow-up aerobic reaction, improves whole biochemical system to the impact resistance of toxic organic compound, thereby guarantees system stable operation.
