Abstract
The utility model relates to the improvement of filler in water treatment, which is characterized in that the filler is a short hollow tube with opening, which has a 30% to 50% (V/V) filling rate, and the fillers are positioned in a hollow plastic ball. The filler of the utility model can not only exert the advantages of the short hollow tube with opening, but also eliminate the deficiency. In addition, the outside is enclosed by the hollow balls, so the sharp collision in the fillers is largely reduced and the biological film growing condition becomes much better, the biology amount is enhanced by 30% to 40% and the silt amount is also reduced; and the filler will not be broken easily, so the demand for the filler of short tube is reduced. Moreover, the ball shell has large area to bear force, and the filler can flow easily, so the procedure is easy and the enlargement of work is simple. In particularly, after the sewage passes through the ball shell surface spacing, the water power shearing direction is changed, and results in different flow direction of outer carrier and inner filler. For the treatment efficiency is improved, 50% of the filler is saved comparing with the loose short tube filler.
Description
Technical field
Utility model is about to the improvement of water treatment with filler, relates in particular to a kind of combined stuffing that can give full play to hollow open short-tube filling advantage.
Background technology
Water-treatment biological filler has a very important role in the wastewater biological aerobic treatment process, and biological contact oxidation process is the water technology of core especially with the filler, the good and bad wastewater biological aerobic treatment effect that directly influences of its use properties.
The biological wastewater treatment hollow open short-tube filling that Chinese patent 87101072.0,00221983 and 02245596.5 discloses different structure, because it has bigger specific surface area, and the different biological growthing environments of inside and outside two classes, it is a kind of water-treatment biological filler preferably, be particularly useful for biological fluidized bed and floating-medium filtering chamber, have treatment effect preferably.But this type of filler is for obtaining high-specific surface area, general volume is less, for example is generally φ 14 * 10mm, at the practical engineering application main drawback is: the one, and less the mistake with current easily of packing volume escaped, the tripping device of intercepting padding material need be set for this reason specially, strengthen construction investment; The 2nd, intercept filler if adopt than fine fack, then can cause filler to gather obstruction again in water outlet place, tend to cause the pool inner water position to raise, also can cause filler to overflow with current; The 3rd, the filler fluidized state is difficult to control, and water distribution, gas distribution uniformity coefficient are required extremely strictness, and fluidisation starts difficulty, engineering amplification difficulty is big, is not to cause filler to float on the surface, difficult fluidisation, be exactly that filler is deposited on the bottom, both all can cause filler uneven distribution in water, influence treatment effect; The 4th, collide acutely between filler, not only microbial film does not promptly come off to age, and microbial film thickness is little, and biomass is few, has also increased the mud generation, and the filler material is had relatively high expectations, otherwise can cause the filler breakage.
Chinese patent 96247275.1 and 200420080851.3 disclosed atypical biological treatment combined stuffings, the former is made up of plastic hollow grid housing and built-in block cavernous body bio-carrier, and the latter is made up of built-in inorganic porous granular filler of hollow out hollow body and counterweight hollow body.The deficiency of this type of filler is: the former can occur block sponge carrier in use for some time and absorb mud, and filler proportion is heightened, and all gathers the bottom at last, be difficult to keep fluidized state, reduced treatment effect, secondly, easily examining is shorter work-ing life because of sponge; The not only inorganic porous granular filler of the latter impacts in water for a long time, easily broken, cause packing specific area to significantly reduce, and because actual inorganic porous granular filler internal void is minimum, along with its internal capillary of microbial growth will soon be ineffective, so the actual aerobic microbiological of can only growing of filler, double oxygen animalcule is difficult to growth, and microbe colony owes abundant on the filler.Though and aforementioned two kinds of fillers, having Anti-lost function preferably, built-in filler in use can gather and is deposited in hollow out hollow body bottom, has limited the fluidized state of filler, therefore is difficult to give full play to the big advantage of specific surface area.
Though above-mentioned filler all occurred before this patent, and different degree input uses, and all shows each inherent defects, all fails to find effective terms of settlement and is improved.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of low to built-in filler requirement, long service life, fluidizing performance is good, maintenance management is simple, the processing efficiency height, and can give full play to the water treatment combined stuffing of hollow open short-tube filling advantage.
The utility model purpose realizes that main the improvement is that the hollow open short-tube filling is positioned in the hollow out ball, reaches the advantage of both giving full play to former hollow open short-tube filling, overcome its deficiency again, can also play Overlay, thereby realizes the object of the invention.Specifically, utility model water treatment combined stuffing is characterized in that by filling ratio being that the hollow open short-tube filling of 30%-50% (V/V) is positioned in the plastics hollow out ball and forms.
Hollow open short-tube filling filling ratio is decided on the treating water Pollutant levels.
The results showed: utility model hollow out spherical shell surface hollow-out spacing and filler diameter ratio are preferably 0.8: 1-1.2; Combined stuffing proportion is preferably 0.8-1g/cm
3Hollow out spherical shell diameter is preferably 80-150mm.
Utility model is formed combined stuffing owing to adopt the hollow open short-tube filling to be positioned in the plastics hollow out ball, not only given full play to the advantage of hollow open short-tube filling, for example specific surface area is big, fluidizing performance is good, also can carry out nitration denitrification denitrogenation synchronously, and overcome its deficiency, filler separates simple, need not to be provided with also fugacity not of complicated filler separator, and can not gather at exhalant region.In addition, owing to have the hollow out bag to enclose outward, sharp impacts chance between interior filling material reduces, not only the biofilm development environment is better, and actual detected hollow open short-tube filling microbial film thickness is greater than natural placement, and the biofilm development cycle is long, it is few to come off, biomass can improve 30-40%, and the mud generation reduces, and helps reducing follow-up sludge disposal expense; And filler cracky not, short-tube filling is required to reduce, also can use as distortion filler in the production process, material is required also can suitably reduce; It is big to add the spherical shell stressed area besides, the easy fluidisation of filler, thereby technology controlling and process is simple, engineering is amplified easily.Especially, combined stuffing sewage changes by hydraulic shear force direction after the carrier spherical shell surface void, cause the incorgruous fluidisation of outer carrier and inner stuffing, thereby forming inner stuffing systemic circulation in water body reaches at the intravital partial circulating of shell, thereby the duration of contact of having improved carrier biofilm and sewage, help improving processing efficiency.Because the raising of treatment effect can be saved about 50% than the bulk storage short-tube filling, thereby reduced the filler cost, has significantly improved processing efficiency.
Below in conjunction with an embodiment, further specify utility model.
