Abstract
The utility model discloses a multiporous microbe carrier structure having projecting function on reducing excess sludge and fixing microorganism, belonging to the technical field of wastewater treatment. Porous layers with different shapes are embedded or supported together by supporting rods. The porous layers can be spheres, cubes, rectangular solids and polyhedrons. The holes of the porous layers are in irregular circular, rhombic, square or rectangular shapes, and the materials of carriers can be the easy processing and corrosion resistance materials or the recovery materials such as plastic, PVC, UPVC, etc. Porous carrier structure used for fixing the microorganism and generating aerobic, micro-aerobic and pressure oxygen environments can promote the decrement of sludge and no generation of the sludge. Thus sewage is processed, and simultaneously sludge is separated from processed water; the service life of the carriers can be extended, and production cost can be reduced. The carriers have the advantages of large surface area and low cost.
Description
Technical field
The utility model belongs to the waste disposal plant field, particularly a kind of porous microbial carrier structure that the minimizing and the microbial immobilization of excess sludge had outstanding role.
Background technology
In activated sludge process and biomembrance process, use the carrier can fixation of microbe, improve the concentration of microorganism in the reactor, thereby can improve the processing efficiency of reactor.Carrier commonly used has fillers such as sand grains, rubble, hard coal, coke, porcelain ring, soft fibers, but these carriers can only form microbial film on the surface of carrier, and biomass is less relatively, and microbial environment is single relatively.
Porous support is the new carrier of a class that receives much concern in recent years, is mainly used in deciding microorganism, the total amount of microorganism in the increase system.And the inside and outside fixing various micropopulation of porous support, for example: poky nitrobacteria and denitrifying bacterium can be assembled in surface and inside, reach nitrated purpose.Simultaneously because oxygen is carrying intravital diffusional resistance, in carrier, form anaerobic zone and aerobic zone easily, make aerobic and anaerobion exists simultaneously, be in anoxic condition near the part of carrier center, cause the environment that helps denitrification process, promote nitratedly, denitrifying to carry out simultaneously.But some present porous supports are because carrier structure control difficulty, effective fixation of microbe, the various environment of formation that can not be stable in carrier.Defend the pretty department of rattan and (defend the pretty department of rattan; Chinese invention patent ZL96106018.2; November 6 2002 Granted publication day) " apparatus and method of purifying waste water " of Ti Chuing are though the middle porous spherical carrier that uses also can play the above-mentioned effect of mentioning; but this carrier is the ball-type carrier that utilizes tackiness agent that stone chippings is bonded; tooling cost is higher; can not carry out extensive Mechanized Processing; and the density of this carrier self is big; processing transportation and install inconveniently can improve the infrastructure investment of sewage work's construction greatly when the carrier amount of needs is big.
Summary of the invention
The purpose of this utility model provides a kind of porous microbial carrier structure, it is characterized in that: this porous microbial carrier structure is nested or be supported in together by steady arm and constitute by three porous layers, white portion is hole 1, black part is divided into wall 2, innermost layer 3, middle layer 4, outermost layer 5, voidage is more than 80%.
Described porous nesting level can be spherical, cubes, rectangular parallelepiped or Polygons.
The constituent material of described porous support is: the synthetic or natural materials of plastics, PVC, UPVC, or use the waste plastic of recycling.
Hole on the described porous layer is irregular, assumes diamond in shape, circle or rectangle.
The beneficial effects of the utility model are: this carrier specific area is bigger, realization is caught microorganism and solid suspended particle, a large amount of microorganisms not only can grow, and in waste water is flowed through the process of carrier owing to have water and particle current difference, suspended solids in the waste water can be captured in the inside of carrier, along with the continuous accumulation of acquisition procedure and continuous growth, the enrichment of microorganism, help the breeding of variform microorganism, simultaneously since the existence of anaerobism, little aerobic and aerobic various environment can promote the minimizing of mud and not produce mud.Therefore when disposing of sewage, mud is separated with treating water, can improve the work-ing life of carrier, reduce production costs.

Embodiment
The purpose of this utility model provides a kind of porous microbial carrier structure, porous microbial carrier structure shown in Figure 1 is by three spheries, cubes, rectangular parallelepiped or polygonal porous layer are nested or be supported in together by steady arm 6 and constitute, white portion is hole 1, and black part is divided into wall 2, innermost layer 3, middle layer 4, outermost layer 5 (shown in Fig. 2 (a) and (b)), Fig. 3 are the porous microbial carrier structure of cube structure, are stuck in big cubical inwall upper support by the rib of small cubes and form.The voidage of each carrier structure is more than 80%.Above-mentioned porous carrier materials is to select for use density less, easily the mass-producing material processed: the synthetic or natural materials of plastics, PVC, UPVC, or use the waste plastic of recycling.Produce the different porous ball layer of diameter earlier separately, fit together then, form porous carrier structure, at the inside and outside formation anaerobism of carrier, little aerobic and aerobic various environment.Hole on the porous layer is irregularly shaped, assumes diamond in shape, circle or rectangle.
Optimum size of the present utility model: the diameter of innermost layer ball: 30~50mm, can overlap a plurality of porous ball layers outside, the diameter of porous ball layer can be: 40~100mm, 60~200mm, 80~300mm.The thickness of each porous ball layer is: 5~200mm, being shaped as of porous ball layer upper section hole: rhombus, circle or rectangle, each is long on four limits: 2~80mm, wall thickness 0.5~4mm.
