Abstract
The utility model relates to an improved biologic contact oxidizing bath sewage treatment plant, which is characterized in that biological film carrier filler adopts a multiaspect hollow ball whose specific gravity is smaller than sewage, and the surface area of the biological film carrier filler is larger than the sewage. The filler ball is limited in the sewerage by a large net, a filler agitating device is arranged around or in the filler, so the biological film can be prompt to renovate.
Description
Utility model relates to a kind of improved biological contact oxidation process device of disposing of sewage.
Known biological contact oxidation pond (tower), pond (tower) body is arranged and be arranged on the intravital filler in pond and oxygenation (aeration) device is formed, biofilm carrier as key part--filler, usually have rigid as hexagon cellular, tubulation filler, the semi soft packing of hollow out plastics disc assembling, and the soft-filler of fibrous type.The hard filler specific surface area is limited, and the duct is very easily stopped up by microbial film; The specific surface area of semi soft packing is also big inadequately; Though the soft-filler specific surface area of fibrous type is bigger, easy balling, these all influence treatment effect.And above-mentioned filler all has a common defective, and promptly effluent quality all can be subjected to the influence that the microbial film cycle comes off and fluctuate.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of contact-oxidation pool of being made up of new packing is provided, and it is little to reach volume, and treatment effect is good, stable effluent quality.
The utility model contact-oxidation pool, comprise pond body and oxygenate apparatus and be arranged on filler in the pond, it is characterized in that described filler is that proportion is little multiaspect hollow ball than sewage, described multiaspect hollow ball is limited in the pond in the sewage by guard, described guard space can make the filler agitator of multiaspect hollow ball filler motion collision in addition greater than the filler actual volume in the body of described pond.Because filling ball exists inside and outside two kinds of surfaces than large specific surface, contact with multiaspect hollow ball filler through the sewage of oxygenation, make filler outside surface and internal surface all cover with microbial film, make wastewater treatment efficiency greatly improve.On the filler body, thicken gradually at living film, when needing to upgrade, the filler agitator orders about multiaspect hollow ball filler play collision friction in bigger guard space, make the outside surface microbial film because of the collision renewal that comes off, the internal surface microbial film is then with the weather aging renewal that comes off, cause on the filler microbial film to be to force to come off and upgrade and the weather aging renewal that comes off hockets, so just guaranteed to exist all the time on the filler active higher microbial film, thereby treatment effect is good and stable, effluent quality is not come off by the microbial film cycle basically to be influenced, thereby has guaranteed the stable of effluent quality.
The described oxygenate apparatus of utility model, can be known various blast aeration, mechanical aeration or blowing engine aerating apparatus, its effect charges into the enough oxygen that supplies microorganism to need in sewage, it can be arranged in the body sewage of pond, can also be as using efflux aerator etc. to be arranged in the inlet channel, these all belong to prior art.Guard is mainly used in retaining and encloses multiaspect hollow ball filler, does not make it float on liquid level because of buoyancy, influences treatment effect, and microbial film is upgraded in order to the filling ball motion collision in its big space.The filler agitator, its effect is to impel to cover with biomembranous filling ball motion collision renewal microbial film in net is played, it can be arranged on filling ball periphery or inner strength or hydraulic jeting device, or be arranged on mechanical agitation device in the filling ball, make filling ball play friction under the acting in conjunction of external surging force and self buoyancy, impel and adhere to its surperficial biofilm detachment renewal.In addition can also serve as the filler agitator by the aeration aerating device that is arranged on the bottom,, when needs force to come off renewal to the filling surface microbial film, then strengthen the aeration air demand, cause the collision of filling ball play as with relatively little air feed aeration aerating.The control of filler agitator can be sent out by electrical control and reach automatization.
Utility model is owing to adopt nature to be suspended in the sewage, specific surface area is big again, and the inside and outside biomembranous multiaspect hollow ball filler of can both growing, and the filler agitator that impels the filling surface microbial film to upgrade, not only can significantly improve sewage treatment capacity (effect) greatly because of biofilm surface is long-pending, and biofilm detachment upgrades to be and forces to come off and weather aging comes off and hockets on the filler, make and have active higher microbial film on the filler all the time, reach stable effluent quality, making water outlet not come off by the microbial film cycle influences.Defectives such as little, the easy obstruction of packing specific area, caking and effluent quality instability in the prior art have been overcome.The increase of packing specific area, but also reduction equipment volume and floor space reduce construction costs.
Description below by 3 indefiniteness embodiment further specifies the utility model.
Fig. 1 is utility model the 1st an example structure synoptic diagram.
Fig. 2 is utility model the 2nd an example structure synoptic diagram.
Fig. 3 is utility model the 3rd an example structure synoptic diagram.
Fig. 4 is a multiaspect hollow ball filling-material structure synoptic diagram.
Embodiment 1: referring to Fig. 1, being set side by side with proportion in oxidation pond body 1 is little multiaspect hollow ball filler 3 and aeration aerating device 5 than sewage, wherein filling ball is limited to FX in the sewage by bigger guard 2, the packing fraction of filling ball in guard is 60-75%, the guard below is a filler agitator perforated pipe 4, perforated pipe links to each other with pressure gas or pressure water source, and body bottom, pond and top are respectively equipped with water inlet pipe and water outlet pipe 6 and 7.
Embodiment 2: referring to Fig. 2, as embodiment 1, wherein filling ball 3 vertically is provided with filler agitator perforated pipe 4 aeration aerating devices 5.
Embodiment 3: referring to Fig. 3, as described above, wherein perforated pipe 4 is arranged on filling ball 3 middle and lower parts, and oxygenate apparatus is to be located at that the jet aerator on the inlet channel 9,8 is a water-distributing device outside the pond.
Annotate: the state of filler shown in the accompanying drawing (come-up) is state before using.
