Abstract
The utility model discloses a composite particle biological carrier for water treatment, which is used for biological treatment to water quality. The utility model has the characteristics of moderate density and strong affinity to microorganisms. The outer surface of a basal body of the carrier is at least packed with one surface layer which has a better affinity to the microorganisms; material of moderate density, easy production and low cost is adopted for the basal body; material which has a better affinity to the microorganism is adopted for the surface layer. Thus, the utility model effectively solves the problems of the existing biological carrier of improper density and poor affinity to the microorganisms or high cost and provides the composite particle biological carrier for water treatment which has the characteristics of proper density, strong affinity to microorganisms, low cost and easy manufacture and production. The utility model can select the size and the density of the basal body or regulate the thickness of the surface layer according to the condition of the water quality which is about to be treated and the optimum density which is needed for the carrier to reach when the carrier is produced and manufactured. The utility model can be widely suitable to be used in occasions which need to carry out biological treatment to the water quality, and the treating effect and efficiency of a water treatment system are improved.
Description
Technical field
The utility model relates in a kind of water treatment occasion the bio-carrier that uses when water carried out a biological disposal upon, especially a kind of composite particles bio-carrier that is used for sewage disposal.
Background technology
At present, bio-carrier commonly used has multiple material can supply to select for use in the water-treated prod, monomeric substances such as quartz sand, gac, haydite, granulated glass sphere, plastics, polymkeric substance for example, they mostly are particulate state, common characteristic is that specific surface area is big, can be for attached growth of microorganisms provide bigger growth area, thus the content of microorganisms of water treatment system improved, reach the purpose of efficiently disposing of sewage.But existing carrier has the following disadvantages:
The one, the problem of microorganism avidity.Because the physical property difference of carrier surface, the microorganism avidity of carrier differs greatly, the microorganism avidity that has a little less than, the microorganism avidity that has is very strong, so, the microbial growth effect is also different on the carrier surface, and just different to the requirement of water treatment system, the water treatment effect is also different with efficient.
The 2nd, the problem of density.Because carrier inside structure and density difference, so its flow state difference, the power that water treatment system is consumed when flowing is also different, and the consumption of power that density is big is big, and mechanical wear is also big, and carrier damages easily and runs off; Density floats over the surface of water less than the carrier of water, and flow state is poor, and system's content of microorganisms is not high, and the microorganism effect of settling is poor, and the water treatment effect is also undesirable.
The 3rd, the production cost problem.Some lower-cost carriers are not the density discomforts, are exactly that microorganism avidity is relatively poor; The carrier that some microorganism avidity are strong, its production cost is very high, and the investment of water treatment system and running cost are also high, are unfavorable for promoting the use of.
The utility model content
Because density and treatment effect and the big deficiency of efficiency variance that the difference of microorganism avidity is caused, technical problem to be solved in the utility model provides suitable, strong to the avidity of microorganism the water treatment composite particles bio-carrier of a kind of density in order to overcome existing different bio-carrier.
The technical scheme that its technical problem that solves the utility model adopts is: this water treatment composite particles bio-carrier is that the outside surface at matrix is enclosed with the top layer that one deck at least has better microorganism avidity.Matrix can adopt the material that density is moderate, production is easy, with low cost, as quartz sand, gac, haydite, granulated glass sphere etc.; The top layer can be adopted has better microorganism avidity and the high material of physical strength, as rubber, polymkeric substance, plastics etc.
As to further improvement in the technical proposal, the top layer is made of porous materials, for example porous rubber or polymkeric substance etc.Like this, because the space, top layer is more, specific surface area increases, thereby has better microorganism avidity.
As to further improvement in the technical proposal, the external diameter on top layer is 1～5mm.
As to further improvement in the technical proposal, its density of water treatment composite particles bio-carrier after making is 1.0 * 10
3Kg/m
3～3.0 * 10
3Kg/m

The beneficial effects of the utility model are: owing to adopted the technical scheme of wrapping up the top layer on the surface of matrix, and matrix adopting density is moderate, produce material easy, with low cost, the material with better microorganism avidity can be adopted in the top layer, make it solve existing bio-carrier or density discomfort or microorganism avidity is poor or cost is high problem effectively, it is suitable to obtain a kind of density, and microorganism avidity is strong, production cost is low, manufacture easy water treatment composite particles bio-carrier.Also can regulate the thickness on top layer, can be applicable to the occasion that to carry out a biological disposal upon to water quality widely according to pending water quality situation and the required optimum density that reaches of carrier.
These product have following characteristics: 1, density is suitable: the density of carrier is slightly larger than water, and need not big power in water can flow preferably, and natural subsidence is good; 2, specific surface area is big: at the strong material of affinity of compound one or more layers microorganism of outside surface parcel of common carrier such as quartz sand, haydite, granulated glass sphere etc., and keep original particle form substantially, parcel compound material also can be selected porous material for use, to increase the specific surface area of carrier; 3, the affinity of microorganism is strong: the top layer of newly adhering to (parcel) is a microorganism hobby material, has good microorganism avidity, as materials such as rubber, polymkeric substance, plastics, the carrier surface attached growth of microorganisms is easy, biotic potential is strong, easily form granule sludge, can improve microorganism concn in the water treatment system greatly; 4, production cost is low: the carrier kernel is common cheap material, and occupy bigger ratio, and having good microorganism avidity and be worth higher parcel composite bed, proportion is less, thereby make the total cost of carrier reduce the cost performance height of carrier.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Be labeled as among the figure: matrix 1, top layer 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, water treatment composite particles bio-carrier of the present utility model is that outside surface at the moderate matrix 1 of density is enclosed with the top layer 2 formed particles that one deck at least has better microorganism avidity.The density of the carrier granule that forms is slightly larger than water, and need not big power in water can flow preferably, and natural subsidence is good.Matrix can adopt the material that density is moderate, production is easy, with low cost, and as quartz sand, gac, haydite, granulated glass sphere etc., its density is 0.8～5 * 10
3Kg/m
3The material with better microorganism avidity can be adopted in the top layer, as rubber, polymkeric substance, plastics etc.Top layer 2 possesses simultaneously preferably that biological affinity is strong, physical strength good, the characteristic of antiacid alkali, and top layer 2 can use porous material, with increasing specific surface area, and for example porous rubber, porous polymkeric substance etc.After making, the external diameter on top layer 2, just the external diameter of carrier is preferably 1～5mm, and the density of carrier is 1.0 * 10
