Abstract
The utility model discloses a hydrolytic acidification pool which comprises a hydrolytic acidification pool body, a water inlet zone, a gas distributing zone, a water outlet zone, a filler zone and a sludge deposit zone. The hydrolytic acidification pool is characterized in that the water inlet zone comprises four sections, water enters from the side surface of the upper part of the sludge deposit zone in the hydrolytic acidification pool and is uniformly distributed, a horizontal perforated pipe is arranged in the water inlet zone, and is uniformly provided with holes with sizes of 10mm and directions vertical to a horizontal direction. The hydrolytic acidification pool has the advantages of simple structure, and no need of backflow and arrangement of a deposit pool.
Description
Technical field
The utility model relates to a kind of hydrolysis acidification pool, especially relates to the hydrolysis acidification pool that improves biodegradability in the sewage treatment process, belongs to the water supply and sewage work technical field.
Background technology
In sewage treatment process, biological process has obtained utilization widely because processing cost is low in sewage treatment industry.Sewage all can influence the last effect of hydrolysis acidification pool at the structure of hydrolysis acidification pool, the residence time, water distribution manner, current, filler etc.Therefore, the structure of anoxic acidulated pool, the residence time, water distribution manner, current, filler etc. are in the developing important topic of sewage treatment industry.
Hydrolysis acidification pool is one of crucial structures in the WWT AO technology.Sewage gets into hydrolysis acidification pool through after the pre-treatment, hangs with biologic packing material in the pond; When organism is complex construction in the water; Acidication bacterium on the filler utilizes ionized H+ of H2O and-OH that the C-C in the organic molecule is opened, and an end adds H+, an end adding-OH; Can long-chain be hydrolyzed to short chain, side chain and become straight chain, ring junction to constitute straight or branched, improve the biodegradability of sewage.The processing efficiency that helps the back segment sewage treatment process.
Existing hydrolysis acidification pool structure formation, water distribution manner commonly used are a lot, and according to the characteristics of different quality, it is fixed that the residence time need come according to organic kind, concentration, temperature on average, and the section area in the pond is also relevant with upflow velocity.Water distribution manner is actual relevant with the WWT operation.Data shows that the structure formation of hydrolysis acidification pool is a lot, and having water outlet needs settling tank, needs to reflux, and the spoil disposal pipeline is prone to shortcomings such as obstruction.Therefore it is necessary that the structure formation of optimizing hydrolysis acidification pool solves these problems.
Summary of the invention
The purpose of the utility model provides a kind of hydrolysis acidification pool that does not need second pond and mud return-flow system.
In order to realize above purpose, the technical scheme that the utility model adopts is: a kind of hydrolysis acidification pool comprises hydrolysis acidification pool pond body, inhalant region, cloth gas area, exhalant region, packing area, mud accumulation area; Said inhalant region is divided into four sections, mud accumulation area upper side water inlet in the pond, water distribution uniformity; Inhalant region is provided with horizontal perforated pipe; Take even perforate, the perforate size is 10mm, and direction is vertical with horizontal direction.
Said exhalant region is the profile of tooth effluent weir.
The bucket of said mud accumulation area is the taper bucket, and bucket and level are 60 degree and are provided with, and are furnished with the spoil disposal pipeline all around in the bucket, and the spoil disposal position is on bucket top, and the bottom is provided with blow-down pipe.
The metal precast frame is adopted in described packing area, and graticule mesh is used in the bottom, and filler uses the urethane uniform filling to arrange.
Described gas distribution is distinguished four sections air inlets, and mud accumulation area top is provided with gas distribution pipe in the pond, adopts the even gas distribution of perforated pipe.
The utility model does not need return-flow system and secondary sedimentation basins, passes through gravitational settling behind the aged biofilm detachment to bucket, and the deposition in the bucket is through the gravity spoil disposal.Gas distribution system has two kinds of effects, and a kind of is a spot of dissolved oxygen to the anoxic microbial film to be provided, and another kind is when the aged microbial film can't normally come off, and carries out stripping through a large amount of aerations.
In sum, the utlity model has simple in structure, do not need to reflux, operational management is advantage easily.
Description of drawings
Fig. 1 is the structural plan synoptic diagram of the utility model;
Fig. 2 is the A-A diagrammatic cross-section of the utility model structure of Fig. 1;
Fig. 3 is the B-B diagrammatic cross-section of the utility model structure of Fig. 1;
Among the figure, the 1st, inlet channel, the 2nd, outlet conduit, the 3rd, the pond body, the 4th, the packing area, the 5th, mud accumulation area, the 6th, emptying spoil disposal pipeline, the 7th, aerated conduit, the 8th, go out water channel.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is specified.
Can know that from Fig. 1, Fig. 2 the utility model comprises settling tank inlet channel 1, outlet conduit 2, pond body 3, packing area 4, mud accumulation area 5, emptying spoil disposal pipeline 6, aerated conduit 7, goes out water channel 8.Inlet channel is divided into four-section water-feeding, and water outlet is concentrated through water storage tank and discharged, and mud accumulation area and level are 60 degree and are provided with, and the packing area links to each other with the mud accumulation area bucket.Water outlet comprises outlet conduit 2 and goes out water channel 8 that effluent weir adopts the profile of tooth effluent weir, and scum board is set on the effluent weir.The mud scum silica frost is got rid of through the scum silica frost mouth of exhalant region.Water inlet is " word " and arranges that the perforation water outlet is set, and perforation size is 10mm, evenly perforate, and direction and horizontal vertical, it is trivial that sewage gets into filler.Mud accumulation area is the taper bucket, and bucket and level are 60 degree and are provided with, and shore pipe road 6 is set under the bucket.
Working process: sewage gets into hydrolysis acidification pool pond body from inlet channel 1; In the entering pond of the inlet channel 1 from Fig. 23, under the effect of settled organism, the organism in the sewage obtains removing sewage in packing area 4; Mikrobe on the filler obtains a spot of dissolved oxygen from aeration; Behind the aged biofilm detachment, deposition gets into mud accumulation area, because the mud accumulation area bottom is 60 degree angles with level; Slide to mud accumulation area 5 under the mud, handle back sewage and get into next treatment scheme unit with outlet conduit 2 through going out water channel 5.
