Abstract
The utility model provides a honeycomb biofilter, wherein the lower part of a filter body is provided with a water inlet distribution zone; a distribution hole pipe is arranged in the water inlet distribution zone; the lower part of the water inlet distribution zone is provided with a water inlet distributor; one side of the water inlet distribution zone is provided with a backwashing air pipe; the upper part of the water inlet distribution zone 1 is provided with a suspended filtering material layer; the upper part of the suspended filtering material layer is provided with a water outlet zone; and a backwashing drainage pipe is arranged between a water inlet pipe and the backwashing pipe. The honeycomb biofilter has the advantages that the treatment efficiency per unit volume is high, the degradation capacity is strong, the treatment capacity is greatly improved, and the honeycomb biofilter is applicable to purifying treatment for various water sources.
Description
Technical field
The utility model relates to provides a kind of active area big, the honeycomb biological filter that is used for the water purification of processing efficiency height and long service life.
Background technology
Current, sewage disposal is adopted usually and is handled quantitatively dropping into liquid chlorine or sodium hypochlorite solution after the settlement of sewage more in proportion, and the shortcoming of this treatment process is that the demand of treatment agent is big, the cost height; The employing liquid chlorine is disinfected also might take place to reveal and is led to a disaster, and causes secondary pollution.Other has a kind of usual way is to adopt biofiltration technology, some both had been set in filtration has easily formed biomembranous materials, utilizes microbial film to come organism in the degradation water, and water is purified." biological wastewater treatment filler unit " disclosed in Chinese patent CN2060442U, promptly in the waste water filtering pond, be provided with a kind ofly, on the wire fibrous bundle, inoculate to handle and make it to generate microbial film and come the desires such as organism in the degradation water to remove material by some linear fiber filler beams that are connected on the connection cord.This deficiency of serving as biofilm carrier with the linear fiber bundle is that the space that self occupies is big, and specific surface area is little, thereby causes active area little, and processing efficiency is not high; Owing to the matter of linear fiber Shu Benshen, long period of soaking is easy to damage in sewage simultaneously, and work-ing life is not long.
Summary of the invention
The purpose of this utility model is intended to solve the above-mentioned deficiency of prior art, provides a kind of active area big, the honeycomb biological filter that is used for the water purification of processing efficiency height and long service life.
The purpose of this utility model realizes by following measure, the body bottom, pond of honeycomb biological filter is provided with into water water distributing area 1, in the water inlet water distributing area 1 dispensing orifice pipe 12 is housed, into water divider 10 is arranged at water inlet water distributing area 1 bottom, water inlet water distributing area 1 one sides are equipped with back flushing blast main 9, suspended filter material layer 2 is arranged at water inlet water distributing area 1 top, suspended filter material layer 2 is particles filled by honeycomb, exhalant region 3 is arranged at suspended filter material layer 2 top, exhalant region 3 one sides are water outlet device 4, and water outlet device 4 connects rising pipe 8, and spacer plate 5 is housed in the exhalant region 3, be connected back flushing water shoot 7 between water inlet pipe 6 and the backwash tube 11, back flushing water shoot 7 is equipped with butterfly valve 13.
Honeycomb particle in the above-mentioned suspended filter material layer 2 is arranged by granular size classification from down to up successively, and described honeycomb particle is a porous honeycomb stone.
Honeycomb particle diameter in the above-mentioned suspended filter material layer 2 is 5-15cm.
Above-mentioned pond body is the polyester integral structure.
Above-mentioned pond body is the integral type steel construction.
Principle of work of the present utility model is: filtrate is made of grating honeycomb particle, and this honeycomb particle that utilizes is made the biological filtering layer that the filtering layer filtrate constitutes, and its microbial film is to be main component with the zoogloea, is aided with football shirt bacterium, algae etc.; Biological membrane biological mainly is the ciliate of sessile form and the ciliate of swimming type, and filter tanks such as the wooden dipper body worm cleaning that also includes wheel animalcule, nematode, oligochaetes in the filtering layer is biological.Effluent stream during through filtering layer because the biochemical action of the contact of filtrate absorption physics chemical action and microorganism, suspended substance, organism, virus, germ, parasitic ovum and some toxic substances in the sewage degraded remove or transform, reach the purification purpose.
The biological filtering layer of particulate in the utility model is made filtrate with small honeycomb particle and has been improved the biomembranous specific surface area of formation greatly, biomembrane area is big, easy to be filmed, be convenient to adhering to, breed, growing of microorganism, microbial population and quantity are all bigger, the processing efficiency height of unit volume, degradation capability is strong, effective, the biological filtering layer of particulate can steady in a long-termly be moved.Sewage is behind this filtering layer, and the non-soluble organism in the sewage is converted into deliquescent organism, makes the discharge water after the processing can be used further to field irrigation, realizes waste water reclaiming, also can reduce organic accumulating in the biological filtering layer simultaneously, prolongs the work period.National second-stage treatment requirement can be reached to general municipal wastewater, emission standard can be reached hospital sewage is sterile-processed.
