Description
Technical field
The invention belongs to technical field of sewage, be specifically related to integral bio zeolite beds-membrane bioreactor waste disposal plant.
Background technology
Apply to aspect the WWT in biotechnology at present; Biozeolite bed or membrane Bio-reactor Technology are two kinds of waste disposal plants that extensively adopt; Because the two is to separate to carry out WWT; The simple biozeolite bed sewage treatment device that uses exists in the sewage solid-liquid separation effect poor, and to the inadequate shortcoming of organic macromolecule mass degradation of difficult degradation; And use the membrane bioreactor waste disposal plant merely, it is poor that the ammonia nitrogen in high density adaptive adjustment capability difference of sewage is caused its ammonia nitrogen in high density processing power.In addition, the biozeolite bed sewage treatment device that uses separately now or the volume of membrane bioreactor waste disposal plant are generally bigger, have inconvenience for its construction, installation and operation.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists; The object of the present invention is to provide a kind of integral bio zeolite beds-membrane bioreactor waste disposal plant; Biozeolite bed unit and membrane bioreactor unit are combined; Provide a cover to be applicable to the ammonia nitrogen absorption ability waste disposal plant strong, simple and compact for structure that industrial sewage is handled, and have the sewage good effect of separating solid from liquid and for the sufficient advantage of organic macromolecule mass degradation of difficult degradation.
In order to achieve the above object, the technical scheme that the present invention adopted is:
Integral bio zeolite beds-membrane bioreactor waste disposal plant; The container that comprises an opening; The both sides that internal tank is separated with dividing plate 5 are respectively arranged with filling natural zeolite filler and biozeolite bed unit 4 that is conducted with water inlet pipe 1 and the membrane bioreactor unit 7 that is conducted with rising pipe 8, and described dividing plate 5 is suspended in the container.
The below of described biozeolite bed unit 4 and membrane bioreactor unit 7 is provided with aerating apparatus 9.
Said biozeolite bed unit 4 is followed successively by water inlet buffer zone 2, supporting layer 3 and the packing layer that is conducted with water inlet pipe 1 from the bottom up; Its aspect ratio is 1: 1: 5; Separate by porous barrier between water inlet buffer zone 2, supporting layer 3 and the packing layer, wherein filled natural zeolite in the packing layer.
The volume ratio of described biozeolite bed unit 4 and membrane bioreactor unit 7 is 1: 3.
Described biozeolite bed unit 4 is that the natural zeolite of 3-5mm is a carrier filler with the particle diameter.
Described membrane bioreactor unit 7 is a vertical.
Through biozeolite bed unit 4 and membrane bioreactor unit 7 are combined; Provide a cover to be applicable to the ammonia nitrogen absorption ability waste disposal plant strong, simple and compact for structure that industrial sewage is handled, and have the sewage good effect of separating solid from liquid and for the long and sufficient advantage of degrading of the organic macromolecule mass degradation time of difficult degradation.
Description of drawings
Accompanying drawing is a working state schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done more detailed explanation.
Shown in accompanying drawing; Biozeolite bed-membrane bioreactor waste disposal plant; Comprise filling natural zeolite filler and the biozeolite bed unit 4 that is conducted with water inlet pipe 1; Described biozeolite bed-membrane bioreactor waste disposal plant structure is container-like; The membrane bioreactor unit 7 that its inner both sides of separating with dividing plate 5 are provided with described biozeolite bed unit 4 respectively and are conducted with rising pipe 8, described dividing plate 5 is suspended in biozeolite bed-membrane bioreactor waste disposal plant.The below of described biozeolite bed unit 4 and membrane bioreactor unit 7 is provided with aerating apparatus 9.Said biozeolite bed unit 4 is followed successively by water inlet buffer zone 2, supporting layer 3 and the packing layer that is conducted with water inlet pipe 1 from the bottom up, and its aspect ratio is 1: 1: 5, is separated by porous barrier between water inlet buffer zone 2, supporting layer 3 and the packing layer.The volume ratio of described biozeolite bed unit 4 and membrane bioreactor unit 7 is 1: 3.Described biozeolite bed unit 4 is that the natural zeolite of 3-5mm is a carrier filler with the particle diameter.Described membrane bioreactor unit 7 is a vertical.
Principle of work of the present invention is: when sewage gets into water inlet buffer zone 2 through water inlet pipe 1; Start the aerating apparatus 9 of the below of biozeolite bed unit 4 and membrane bioreactor unit 7; Like this under the upwards promotion of this aerating apparatus 9; Just the sewage upward flow is passed through packing layer through supporting layer 3; Natural zeolite in the packing layer adsorbs the ammonia nitrogen in the sewage subsequently; Then the sewage overflow after the absorption is crossed dividing plate 5 and is got into membrane bioreactor unit 7, membrane bioreactor unit 7 in, the sewage after the adsorption is carried out solid-liquid separation and for the organic macromolecule mass degradation of difficult degradation, simultaneously under the acting in conjunction of the aerating apparatus 9 below biozeolite bed unit 4 and the membrane bioreactor unit 7 in whole biozeolite bed-membrane bioreactor waste disposal plant the inner circulation of formation; Make the inner mikrobe of sewage, mud and microbial film obtain exchange, thereby further reach the WWT effect.
The present invention is through combining biozeolite bed unit 4 and membrane bioreactor unit 7; Provide a cover to be applicable to the ammonia nitrogen absorption ability waste disposal plant strong, simple and compact for structure that industrial sewage is handled, and have to good effect of separating solid from liquid in the sewage and for the long and sufficient advantage of degrading of the organic macromolecule mass degradation time of difficult degradation.The below of described in addition biozeolite bed unit 4 and membrane bioreactor unit 7 is provided with aerating apparatus 9, can fully the sewage that gets into biozeolite bed unit 4 be pushed packing layer fully through its impellent that makes progress and carry out WWT; And said biozeolite bed unit 4 is followed successively by water inlet buffer zone 2, supporting layer 3 and the packing layer that is conducted with water inlet pipe 1 from the bottom up; Its aspect ratio is 1: 1: 5; Separated by porous barrier between water inlet buffer zone 2, supporting layer 3 and the packing layer, such structure can be carried out the absorption to ammonia nitrogen better; The volume ratio of described biozeolite bed unit 4 and membrane bioreactor unit 7 is 1: 3, and such structure can guarantee that corresponding sewage hydraulic detention time is 1: 3 than also, more can let organic macromolecule mass degradation time of difficult degradation long and degraded is abundant; Described biozeolite bed unit 4 is that the natural zeolite of 3-5mm is a carrier filler with the particle diameter; The natural zeolite of this particle diameter can guarantee that it has bigger adsorption surface area; Bio-film colonization is easier to, and also can avoid biozeolite bed unit 4 blockage problem that cause because of the zeolite particle diameter is too small; Described membrane bioreactor unit 7 is a vertical, and such structure can make the film pollution level light, and solid-liquid separation efficiency is high.
