Description

The effectively hydrolyzing acidizing unit of synchronously treating sewage and solid-phase contaminants

Technical field:

The utility model belongs to the environmental protection equipment technical field, relates to a kind of improvement of sewage treatment process equipment.

Background technology:

Sewage disposal is the complex art of energy intensive.For a long time, big, high construction and the operation that hinders China municipal sewage plant to a certain extent of working cost of energy consumption.Investigation shows that China's municipal sewage plant's energy consumption is mainly used in biological treatment oxygen supply and sludge handling process, accounts for more than 60% of Sewage Plant direct operating cost.

Mud is the by product of sewage disposal, calculate with water ratio 97%, volume account for dispose of sewage 0.3～0.5%, the advanced treatment sludge output also will further increase.The dewatered sludge of the annual discharging of China at present is approximately 1.3 * 10 ⁶T, and increasing to surpass 10% speed.The sewage work of Beijing's maximum---Gaobeidian City's sludge of sewage treatment plant is disposed expense and is accounted for more than 1/3 of full factory working cost.A large amount of generations of mud have also caused increasingly serious secondary pollution, and become another bottleneck of municipal sewage treatment industry.Sludge treatment disposal rate is low, and a wherein very important reason is exactly the restriction of investment and running cost aspect.Therefore, mud decrement and resource utilization receive very big concern always, and the less sewage treatment process of research and development sludge yield also is one of important channel that addresses this problem.

In addition, equally also there is " three wastes " problem in sewage work as industrial enterprise, and " cleaner production " of himself enough paid attention to for a long time.Wherein " waste residue " sewage plant sludge of having mentioned promptly according to the principle of " cleaner production ", should be controlled from the source the disposal of mud.The mud decrement technology can be when reducing mud, do not influence the efficient of entire sewage treatment process, though still be in the development research stage now,, certainly will draw attention along with popularizing and the exposure of the existing drawback of mud now of small and medium-sized cities sewage work.

Summary of the invention:

In order to address the above problem, the utility model provides a kind of synchronously treating sewage of mud decrement and effectively hydrolyzing acidizing unit of solid-phase contaminants of can be used for.

The effectively hydrolyzing acidizing unit of this synchronously treating sewage and solid-phase contaminants, comprise: sewage inlet pipe (1), backflow excess sludge batch pipe (2), water conservancy diversion flap (3), Turbulent wing panel (4), perforation tracery wall (5), efficient sloping plate deposition equipment (6), water leg (7), rising pipe (8), storage bucket (9), shore pipe (10) is characterized in that: batch pipe (2), water conservancy diversion flap (3), Turbulent wing panel (4) of backflow excess sludge places in the hydrolysis acidification pool simultaneously with efficient sloping plate deposition equipment (6).

The beneficial effects of the utility model are: in same hydrolysis acidification pool, realize anerobic sowage biological degradation, solid-phase contaminants high efficiency separation expeditiously and hold back, function such as mud is subdued.Before the technology of the aeration tank of sewage aerobic biochemical treatment, can adopt this effectively hydrolyzing acidification technique to replace primary sedimentation pond, by its water side efficient three-phase separation area is set and further strengthens suspended substance and hold back efficient; Simultaneously the second pond excess sludge partly or entirely is back to hydrolysis liquefaction in the effectively hydrolyzing acidification pool, realizes the decrement treatment of solid-phase contaminants and mud; The utility model technology is also by being provided with water conservancy diversion and flow-disturbing members such as flap, fin in the pond, increase the current turbulence and improve thing phase mass transfer, with the clearance of enhanced hydrolysis acidification pool, and can be used as pre-treatment, improve the efficient of subsequent biological treatment technology the solvability organic pollutant.

Description of drawings:

Principle of work as shown in Figure 1, 2, 3.

Fig. 1 is the effectively hydrolyzing acidizing unit structural representation of synchronously treating sewage and solid-phase contaminants;

Fig. 2 is with waveguide stream folded synoptic diagram;

Fig. 3 is different waveguide stream folded synoptic diagram.

Among the figure: (1) sewage inlet pipe, (2) backflow excess sludge batch pipe, (3) water conservancy diversion flap, (4) Turbulent wing panel, (5) perforation tracery wall, (6) efficient sloping plate deposition equipment, (7) water leg, (8) rising pipe, (9) storage bucket, (10) shore pipe.

Embodiment:

Workflow and principle are: sewage enters hydrolysis acidification pool through sewage inlet pipe (1), flow-disturbing through water conservancy diversion flap (3), Turbulent wing panel (4), increase the current turbulence and improve thing phase mass transfer, organic pollutant is separated under the acidification bacteria effect at pool inner water efficiently to be removed, enter efficient three-phase separation area through perforation tracery wall (5) again, current obtain clarification by efficient sloping plate deposition equipment (6), catchment through water leg (7), are discharged by rising pipe (8) at last; Solid-phase contaminants in the current and anaerobic bacterium after efficient sloping plate deposition equipment precipitate and separate or sedimentation on the way, are accumulated in storage bucket (9), can be discharged or backflow by shore pipe (10); The excess sludge of follow-up aerobe processing unit, can enter hydrolysis acidification pool by the backflow excess sludge pipe (2) of batching, in the unitary lower section of the every lattice of hydrolysis acidification pool, with sewage current hybrid perturbation, by obtaining liquefaction and degraded under the acidication bacteriological action in the acidication, reach the usefulness of mud decrement.

The water conservancy diversion flap can be divided into setback plate, different setback plate in the pond, also can will adopt different form combinations with setback plate and different setback plate; The unitary length L of every width of cloth flap ₁Be 200～2000mm, angle is 90 °～150 ° between adjacent two width of cloth flaps; The Turbulent wing panel length L ₂Be 1～200mm, the angle between fin and the flap is 30o～150 °; Adopt the water side to adopt efficient sloping plate deposition equipment that solid-phase contaminants is carried out high efficiency separation and held back, efficient swash plate adopts engineering plastics or glass reinforced plastic, and its swash plate spacing is 20～200mm.
