The utility model has the advantages of having regular shape, high mechanical strength, big specific surface area, strong corrosion resistance, easy processing and making, and no bonding and molding because the density of the particle material is much smaller than the stone material, leaving out the bonding working procedure, enabling to be assembled at the job site, being convenient for transporting, saving transportation cost and avoiding the secondary pollution to water body from the adhesives without using the adhesives.
Description
Technical field
The utility model relates to a kind of bio-carrier, refers in particular to a kind of speed that is used for effluent treatment plant and divides biochemistry ball.
Background technology
Area for Freshwater resources shortage and Urban water supply wretched insufficiency; utilize water source in sanitary sewage, waste water and the conduct of part trade effluent; after purifying; reach the water quality standard of reclaimed water; the situation of water scarcity can be alleviated, the purpose that prevents water pollution and protect environment can be played simultaneously.For sewage is purified, the method that has multiple water to purify, wherein technique for treating sewage of aeration biofilter is a new technology that begins one's study and use in China in recent years, it is reduced investment outlay and working cost, save the area, convenient management, effluent quality is good, can reach the general reuse water standard in city, as choosing of bio-carrier and filtrate in this technology, also only limit to haydite at present, zeolite, medical stone, coke, materials such as slag, its out-of-shape, use the plastics net as carrier though have, all to some extent in physical strength, specific surface area, erosion resistance, surface electrical behavior and wetting ability, hole filter and surfaceness, there is defective in aspects such as density.Because mobile sewage exists the difference of flow velocity, suspended substance in the water is always assembled to the slow place of flow velocity, utilize this phenomenon of wandering about as a refugee to develop the quick-decomposing biological treatment technology, and in this technology, need a kind of new filler that can the above-mentioned bio-carrier characteristic of general performance.
China utility model patent ZL 02253989.1 discloses a kind of speed that is used for effluent treatment plant and has divided biochemistry ball.This speed divides biochemistry ball by the bonding glomerate aggregate of a plurality of particles, and voidage is about 30%～50%, and coating of particles can be sphere or polyhedron, particulate material selection ore or vegetable fibre porous material.Particle is placed in the spherical mould, be bonded into the spheroid that diameter is 5～30cm by tackiness agent, this spheroid is deposited in the biological filter, under the aeration aerating condition, the bio-carrier of characteristics such as formation has regular shape, physical strength height, specific surface area is big, erosion resistance is strong and processing and fabricating is easy, it is a ultimate principle with speed branch technology, assembles organism easily, and quickens the purification of water quality.The speed of this kind structure divides biochemistry ball to adopt the mode that particle is bonding to form spherical shape, need scribble caking agent on the particulate surface like this, and caking agent can stop up the micropore of particle surface, thereby cause the particulate specific surface area to reduce, the adsorptive power that influence speed is divided biochemistry ball, and then reduce purifying water effect.In addition, caking agent soaks in water for a long time, if meeting soluble in water produces secondary pollution to water body.Have, when bonding, particle need carry out extrusion bonded to it in spherical mould again, just can use after needing to wait caking agent fully to solidify then, and demoulding difficulty, this just requires speed to divide biochemistry ball need be before being transported to the working-yard just must to finish in that factory is bonding, is transported to the working-yard again.For the cracked damage that prevents that speed from dividing biochemistry ball to cause because of impact shock in transit, just need to increase transportation cost.As seen, adopt the speed of bonded structure to divide biochemical ball that its unsurmountable shortcoming is arranged.
The utility model content
The purpose of this utility model is exactly at the problems referred to above, and a kind of specific surface area of design is big, technology is simple, the process-cycle is short, not easily broken, transportation cost is low, can not divide biochemistry ball to the speed that water body produces secondary pollution.
The utility model is used for the speed of effluent treatment plant and divides biochemistry ball, place by several porous particles and to form spheroid or approximate spheroid in the spherical guard, the particle diameter of described porous particle is 2.5cm～6cm, and described sphere diameter is 100～600mm, and the proportion of described spheroid is greater than 1.
The utility model is used for the speed of effluent treatment plant and divides biochemistry ball, described porous particle be shaped as sphere and/or elliposoidal and/or polyhedron shape.
The utility model is used for the speed of effluent treatment plant and divides biochemistry ball, and the material of described porous particle is a proportion greater than 1 particle, or proportion is mixed in proportion less than 1 particle with proportion greater than 1 and forms.
The utility model is used for the speed of effluent treatment plant and divides biochemistry ball, and the material of described porous particle is zeolite and or medical stone and or haydite.
The utility model is used for the speed of effluent treatment plant and divides biochemistry ball, and described spherical guard is that two dome-type guards are formed, and two dome-type guards snap together by the grafting barb which is provided with.
Because the density of haydite, slag granules is littler than the density of stone material, and can make at the construction field (site) and assembled formation, both reduced bonding process, can reduce transportation cost again, and kept the vesicular structure of particle surface, improved the specific surface area of fast minute biochemistry ball, and then improved decontamination effect improving, avoided the secondary pollution of caking agent again water body to water body.
The beneficial effects of the utility model are: because the utility model is by the synthetic spheroid of a plurality of groups of grains, be formed with 30～50% voidage between the particle of formation spheroid, the particulate outside surface is attached with microorganism, when current flow through the filter tank that is stacked with speed branch biochemistry ball, form the difference of the inside and outside flow rate of water flow of spheroid easily, and then assemble more organism in the slow place of flow velocity, under the dual function of aerating apparatus and current, organism is slowly moved.In addition, because the difference of the inside and outside oxygen supply condition of spheroid can be created diversified water quality environment, promote purification to water quality and suspended substance.
The speed that the utility model is used for effluent treatment plant divides other details of biochemistry ball and the characteristics can just can be cheer and bright by the embodiment that reads hereinafter and describe in detail in conjunction with the accompanying drawings.
