Description
Technical field
The mud that the utility model relates to producing after the sewage disposal carries out spissated equipment, and what be specifically related to is inclined board type sludge thickener.
Background technology
The preliminary sedimentation tank moisture percentage in sewage sludge of sewage work: 95-97%, secondary sedimentation basins (residue) moisture percentage in sewage sludge reaches more than 99% bulky.Some biological treatment facilities of Treatment of Industrial Water, coagulation etc. also produce a large amount of water-containing sludges, and volume is bigger, all needs to carry out concentration.
The purpose of concentration basin is exactly in order to subtract appearance-particle interstitial water 70%.The water ratio of mud is reduced to 96% by 99%, and the volume of mud can reduce 3/4, and water ratio is reduced to 95% from 97.5, and volume can reduce 1/2, can create advantageous conditions for subsequent disposal after volume reduces.The pond body that it is taper that existing sludge thickener has a bottom, as shown in Figure 1, there is mud discharging mouth 2 bottom of pond body 1, advancing mud pipe 3 enters pond body 1 and extend into pond body 1 lower section downwards from the top of pond body, the top of concentration basin is provided with annular water leg 4, water leg 4 is looped around the inwall place of pond body, rising pipe 5 is arranged on the position, top of pond body and communicates with water leg 4, sludge thickener to sludge handling process in, mud is in the middle and lower part of pond body 1, and body 1 top in pond is supernatant layer, and this process mud is in and lacks the nutriment anoxic condition, anaerobic digestion can occur, it is a succession of biochemical reaction of different bacterium effect.Because the sludge retention time in the sludge thickener is 2d only, and the breeding cycle of methanobacteria is 4～6d, so the anaerobic digestion in the sludge thickener is incomplete, organic concentration height in the supernatant liquor impurity.These supernatant liquors that contain high-enriched organics are back to the front end of preliminary sedimentation tank, aeration tank or treatment scheme, will increase the load of biochemical treatment, influence effluent quality.The less Treatment of Industrial Water of the water yield particularly, the backflow of supernatant liquor can make sewage treatment structure bear higher impact load, has a strong impact on wastewater treatment efficiency.
Summary of the invention
The purpose of this utility model provides inclined board type sludge thickener, and it is used for solving the high problem of supernatant liquor organic concentration behind the existing sludge thickener thickened sludge.
The technical scheme that its technical problem that solves the utility model adopts is: this inclined board type sludge thickener comprises that the bottom is the pond body of taper, there is mud discharging mouth the bottom of pond body, the top of advancing mud Guan Congchi body enters the pond body and extend into body lower section, pond downwards, the top of concentration basin is provided with the annular water leg, rising pipe is arranged on the position, top of pond body and communicates with water leg, the middle and lower part of pond body is the mud district, top is the supernatant liquid zone, the swash plate that be arranged in parallel is installed in the supernatant liquid zone, swash plate is electronegative ganoid sheet material, and swash plate and pond body inwall are fixed together.
In the such scheme between 60 °-75 ° at the swash plate angle of inclination.
Partial impurities material in the concentration basin supernatant liquor is a biological floe, and viscosity and specific surface area are all bigger, and swash plate is installed, can increase the chance that impurity collides mutually, the a plurality of particles in collision back combine, and form the bigger macrobead of quality volume, have strengthened the settling velocity of floc particle.Swash plate has been installed has increased desilting area, according to shallow pool theory, can increase the removal efficient of impurity particle.Between 60 °-75 ° at the swash plate angle of inclination and smooth surface can make under the impurity major part that is deposited in swash plate and slide into sludge blanket, the obstruction that quickens supernatant liquid zone precipitation process and reduce swash plate.
The utlity model has following beneficial effect:
Partial impurities material in the supernatant liquor is generally biological floe, viscosity and specific surface area are all bigger, between two swash plates and on the swash plate, can produce certain cohesion after the collision mutually, generate volume, the flocs unit that quality is bigger, the utility model is by being provided with swash plate, can increase substantially the contamination precipitation efficient in the supernatant liquor, improve the concentration basin effluent quality, make organism as much as possible along with thickened sludge enters in next step anaerobic sludge digestion, in addition, supernatant liquor after handling by the utility model is back to the front end of sewage disposal flow process, can alleviate the impact load of sewage disposal flow process greatly.

Embodiment
As shown in Figure 2, this inclined board type sludge thickener comprises that the bottom is the pond body 1 of taper, there is mud discharging mouth 2 bottom of pond body 1, advancing mud pipe 3 enters pond body 1 and extend into pond body 1 lower section downwards from the top of pond body, the top of concentration basin is provided with annular water leg 4, advancing mud pipe 3 is positioned under the water leg 4, rising pipe 5 is arranged on the position, top of pond body 1 and communicates with water leg 4, the middle and lower part of pond body 1 is the mud district, and top is supernatant liquid zone 6, and the precipitation of thickened sludge is the zone precipitation when just having begun to carry out, in precipitation process, phase mutual interference between the adjacent particle, hinder, the big particle of heavy speed also can't surmount the little particle of heavy speed, and each self-sustaining relative position is constant, and under the effect of cohesion, particle is combined into an integral body and precipitates downwards, and forms clearly liquid-solid interface between the primary water, and precipitation is shown as the interface.Carry out along with spissated, begin to form the zone precipitation, promptly form compression.Particle supports mutually, and the upper strata particle is extruded lower floor's particulate interstitial water under the effect of gravity, mud is concentrated.According to this process, add the swash plate 7 that be arranged in parallel in the supernatant liquid zone 6 of sludge thickener, strengthen contamination precipitation in the supernatant liquor, improve the water quality of water outlet, for the height that strengthens supernatant liquid zone 6 so that swash plate 7 is installed, can increase the height of sludge thickener.
Partial impurities material in the supernatant liquor is generally biological floe, and viscosity and specific surface area are all bigger, between two swash plates and on the swash plate, can produce certain cohesion after the collision mutually, generates volume, and the flocs unit that quality is bigger has quickened precipitation process.But organic concentration is higher in the supernatant liquor, microbial activities is frequent, easily forms sludge blanket on swash plate 7, is unfavorable for spoil disposal, therefore the wide-angle between swash plate 7 adopts 60 °-75 °, material then adopts electronegative sheet material, requires smooth surface, and the impurity of supernatant liquor is generally electronegative, like charges is mutually exclusive, the impurity that helps being deposited on the swash plate falls back to the mud enrichment region again, continues to participate in concentrating of mud, enters follow-up technologies such as digestion after concentrating and further handles.If the sludge concentration of supernatant liquor is big, swash plate 7 is easily stifled, can suitably strengthen swash plate 7 spacings or increase swash plate 7 inclination angles.
