Abstract
The utility model discloses a bio-contact oxidation pond which comprises a water inlet region, a perforation mud discharging region, a gas distribution region, a material filling region and a water outlet region. The bio-contact oxidation pond is characterized in that a sawtooth-shaped mud hopper of a perforation mud discharging system is arranged in a manner of forming a 60-degree angle in a horizontal direction; a hole of a perforation mud discharging pipe is 30mm; and mud can be discharged out of a pond body in a gas extraction manner. A water body in the material filling region runs in a backflow manner; and polyurethane biological stuffing is sequentially arranged in three specifications, namely thick, intermediate and thin, in a water flow direction by virtue of a steel bar framework structure; and a hose aeration system and a scattered flow aeration system are arranged in the gas distribution region and are respectively used for supplying oxygen and updating a film. The bio-contact oxidation pond has the advantages of simple structure, low stuffing blockage rate and convenience in running and management.
Description
Technical field
The utility model relates to a kind of biological contact oxidation pond, especially relates to the biological contact oxidation pond for the treatment of S S, the higher sewage of salinity, belongs to the water supply and sewage work technical field.
Background technology
Bio-contact oxidation is the biomembrance process with activated sludge process characteristics, has both advantages concurrently, therefore in the sewage treatment area widespread use.Filler is set in the pond, with it as biomembranous carrier, the biotype of growth reproduction is abundant on the microbial film, kind is various, food chain length and complexity, sewage is in flowing through the process of biofilm surface, and the organic pollutant in the sewage is by the microorganism adsorption in the microbial film, and by the diffusion of oxygen to microbial film inside, the effects such as bio-oxidation occur in film, thereby finish the decomposition to organic pollutant.
The principal element that affects biological contact oxidation process water treatment effect is the homogeneity of filler and water distribution, aeration.Present biological water technology extensively adopts radical sedimentation basin as medium sediment pool, all there is mud scum phenomenon in various degree, the SS level is higher owing to press from both sides mud in water outlet, therefore, filler stops up easily in the pond, can not realize operation steady in a long-term, and when carrying out the filler cleaning and changing operation, difficulty is very large, and the support spoilage is high, causes the device operational and administrative expenses high.Aerating system is positioned at the bottom of the pond in addition, maintenance difficulty during damage, and the biofilm detachment of cultivating under high salt high-calcium water-quality condition is difficult, and aging serious.Therefore, optimizing the biological contact oxidation pond structure, to solve these problems be necessary.
Summary of the invention
The purpose of this utility model provides a kind of filler and is difficult for obstruction and cleaning and replacing conveniently, and aeration efficient is high, and microbial film can upgrade in time, and aerating system overhauls easily biological contact oxidation pond.
In order to realize above purpose, the technical solution adopted in the utility model is: a kind of biological contact oxidation pond comprises inhalant region, perforation sludge discharging area, cloth gas area, packing area, exhalant region; The perforation sludge discharging area adopts prionodont bucket and perforated sludge discharge pipe to collect deposition, adopts the mode of air lift that the pond body is discharged in deposition again; The urethane filler is adopted in packing area sewage deflector type operation, and utilizes the steel bar framework structure to divide carse, medium and small three grades to install successively with water (flow) direction; The cloth gas area is provided with flexible pipe aerating system and diffusing aerating system.
Described inhalant region, exhalant region adopt the form of overflow weir to guarantee the Inlet and outlet water homogeneity.
The prionodont bucket of described perforation sludge discharging area and horizontal direction are 60 degree and arrange, and the perforate size is 30mm on the perforated sludge discharge pipe.
Described packing area filler adopts precast reinforced framework to fix, and precast reinforced framework is installed by the mode that supports or hang, and can utilize skeleton construction directly with crane filler to be hung out the pond body when cleaning, changing filler or maintenance aerating system.
Described flexible pipe aerating system and diffusing aerating system are installed in the position of 300mm at the bottom of the pond, utilize the numb stone pier to be fixed.
In sum, the utlity model has simple in structure, the difficult obstruction of filler, operational management is advantage easily.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
By Fig. 1,2,3 as can be known, the utility model comprises inlet channel 1, outlet conduit 2, and overflow weir 3, perforation sludge discharging area 4, packing area 5, perforated sludge discharge pipe 6, stripping tube 7, air prop up valve 8, spoil disposal open channel 9, zig-zag bucket 10, cloth gas area 11.The form of overflow weir is all adopted in the turnover pool, and the sludge discharging area of boring a hole adopts and level is 60 ° prionodont bucket and the big or small perforated sludge discharge pipe collection bed mud for 30mm of perforate, and the mode with air lift drains into deposition the spoil disposal open channel 9 that is built in the inhalant region top again.Cloth gas area 11 is located at 5 belows, packing area, and filler is fixed by the steel bar framework structure, utilizes support (large angle steel supports) or the mode that hangs that framework is fixed in the pond, and sewage enters as shown by arrows in FIG. deflector type operation behind the packing area.
Working process: sewage enters the perforation sludge discharging area through inlet channel 1, remove the SS that folder mud form exists in the water through the natural sedimentation effect, then enter packing area 5 through overflow weir 3, sewage adopts the deflector type operation scheme fully to contact with biomembranous with realization in the packing area, organism in the sewage obtains removing under the effect of packing area surface biological film, microbial film utilizes the flexible pipe aerating system to obtain the dissolved oxygen demand, and realize biomembranous renewal by the intermitten service of diffusing aerating system, handle rear sewage and enter next unit for treating water through outlet conduit 2.
