Abstract
Inside the reactor, there are dynamic stuffing fixed onto the turnable stuffing support and biological membrane attached the stuffing. The biological membrane is always in moving state relatively to treated water, the stuffing has one linear speed of 0-1.5 m/s and the stuffing support rotates at 0-10 rpm. The pollutant in the treated water and dissolved oxygen contact with the biological membrane fully and are adsorbed onto the biological membrane. During the metabolism of microbe, the adsorbed pollutant is oxidized by the dissolved oxygen and degraded by the microbe and water is purified. The present invention has many advantages and is suitable for treatment of water in different quality.
Description
(1) technical field
The invention belongs to water technology, be specifically related to a kind of dynamic stuffing and biological membrane water treating method.
(2) background technology
Biomembrance process is a kind of by handle the aerobic treatment method of waste water attached to the microbial film on certain object.The biomembrance process water technology mainly contains: biological filter, blodisc, bio-contact oxidation, three-phase fluidized bed facture.These treatment processs have the following disadvantages: low, the easy obstruction of biological filter facture load, give an offensive smell, have the filter tank fly, it is limited to handle the water yield, now seldom adopts; The circular discs of blodisc facture is partially submerged in the water, and the disc surface of rotation is long-pending little, and current contacts with microbial film is intermittent, and that processing is loaded is low, disc cost height, surface biological film amount are few, be subjected to weather effect big; Biological contact oxidation process adopts fixed filler, and filler all is immersed in the water, and the aeration water distribution is inhomogeneous, mass-transfer efficiency is low, the processing load is low and filler easily stops up, and microbial film upgrades slow; The three-phase fluidized bed facture utilizes current or air-flow as power, with short grained filler fluidisation, be the higher method of present water treatment efficiency, but its power consumption is big, design requirements is high, is not suitable for the processing than big yield.
(3) technology contents
The technical problem to be solved in the present invention be improve microbial film and former water contact uniformity coefficient and mass-transfer efficiency and filler blockage problem.
Filler is biomembranous carrier, and the way of contact of filler and former water is the core technology of biofilm reactor.If pending current current when static filler contact inhomogeneous with microbial film on the filler, be that the part current do not reach microbial film, perhaps the degree of water and filling surface relative movement is poor, mass-transfer efficiency is restricted, and biomembranous cleaning action just can not be given full play to, and influences the water treatment effect, in addition, a little less than the outmoded microbial film scouring intensity of current to static filling surface, microbial film upgrades slow, and filler easily stops up during high loading.
Adopt dynamic filler in the reactor of dynamic stuffing and biological membrane water treating method of the present invention, filler is fixed on the interior rotatable stuffing frame of reactor, rotate with stuffing frame attached to the microbial film on the filler, microbial film and pending water are in the relative movement state all the time, filler line of motion speed 0～1.5m/s, stuffing frame rotating speed 0～10 commentaries on classics/min, the filler of rotation makes dissolved oxygen and the Pollutant distribution in the reactor even, pollutent in the pending water can fully contact with microbial film with dissolved oxygen, and be adsorbed onto rapidly on the microbial film, microorganism is in its metabolic processes, and the pollutent that utilizes the dissolved oxygen oxidative degradation in the water to be adsorbed is purified water quality.
Adopt the present invention can obviously improve former water in the reactor and contact inhomogeneous and the uneven phenomenon of reactor bottom aeration water distribution, treatment effect is significantly improved with microbial film on the filler.The present invention has the mass-transfer efficiency height, and anti impulsion load, filler are difficult for stopping up, low power consumption and other advantages, and it is simple in structure, and floor space is little, and construction costs is low, is applicable to the processing of multiple water quality., treatment effect higher with present volumetric loading rate three-phase fluidized bed preferably compared, and the volumetric loading rate can improve more than 1.5 times, and outlet water organic substance content BOD is less than 10mg/L, under the identical treatment condition energy consumption only be its 50%.
(4) description of drawings
Accompanying drawing is dynamic biological film water facture reactor and schematic flow sheet.
(5) specific embodiment
The present invention adopts the dynamic biological film water to process, design stuffing frame diameter 6m, and depth of water 5m fills out Material line of motion speed 0.3m/s, stuffing frame rotating speed 1 turns to/min, and rotating stuffing frame 1 is lifted on circle On the truss 8 of shaped reaction device 9 upper ends, be hung with some fillers 7 on the stuffing frame 1, filler adopts medium-soft The property fibrous material make.
Above-mentioned stuffing frame 1 is made up of bracket 2, bottom bracket 3, rotating shaft 6, tensioning apparatus 4, filler 7, Carriage is fixed in the rotating shaft up and down, and tensioning apparatus is made up of some ropes, rope be connected up and down carriage it Between, filler is fixed on the rope, and rotating shaft is driven by power set 5, as shown in the figure.
The stuffing frame that the present invention rotates can vertically or be horizontally set in the biofilm reactor.
The present invention adopts dynamic filler, and during operation, pending water flows through from the filler that reactor rotates, The biomembrane that the dependence filling surface adheres to is with purificating raw water, and filler has been strengthened water and filled out in rotation process The relative motion of material has improved the contact uniformity and mass-transfer efficiency, and aging biomembrane is upgraded in time, Prevented the obstruction of filler, and can regulate according to the variation of raw water quality the rotating speed of filler, to adapt to difference The requirement of water treatment.
According to the relation that biofilm biomass is directly proportional with packing specific area and mass transfer rate is directly proportional with the relative motion degree of filler and water, the dynamic stuffing and biological membrane water treating method of the present invention's design is compared with biological rotating disk facture, bio-contact oxidation facture, three phase fluidized bed facture: volumetric loading (kg BOD5/
m
3D) be respectively: 35～40,1,1.8,20; 70～80,2 sludge concentration (g/L) is respectively:, 3.6,10～30.
From above parameter can illustrate dynamic stuffing and biological membrane water treating method volumetric loading height, sludge quantity big, The water treatment efficiency height because filler is kept in motion all the time, has thoroughly solved the biomembrane that comes off and has stopped up The problem of filler makes aging biomembrane be upgraded timely simultaneously, can adapt to different quality and process Requirement.
