Description
The utility model belongs to technical field of sewage, and it relates to a kind of pure oxygen-jet-compound bio film sewage treatment device.
In the sewage treatment in modern times, biological treatment is to use one of method the most widely, and wherein biomembrance process is a kind of aerobic treatment method by disposing of sewage attached to the microbial film on certain object.It comprises biological filter process, bio-disc system, biological contact oxidation process etc.The original form of biomembrance process is a biological filter process, and it is to be foundation with the soil self-purification principle, on the practical basis of sewage irrigation, through intermittence filter tank and contact filter and artificial bio-membrane's facture of growing up.The biological filter adopts rubble as filtrate, and the individual activity of the microorganism that exists with occurring in nature is handled sewage, thereby its volume load and organic removal rate are lower, belongs to the biological filter of underload.Adopt plastic filtering material in recent years, treatment effect increases, but still has the shortcoming that costs an arm and a leg with the denitrification effect difference.
The purpose of this utility model is in order to overcome insoluble insoluble organic of traditional water technology and ammonia-N removal rate problem, to design a kind of waste disposal plant that provides at present water body severe contamination.
The purpose of this utility model is achieved in that this device mainly is made up of mixed flow biochemical reactor (5), compound bio filtrate (9), (10), biological filter (9), (10), several parts of circular oxygenation device (13), with being connected communicating pipe.
1 mixed flow biochemical reactor
This reactor (5) has been installed a plurality of ejectors on its water inlet pipe, the below is provided with mud discharging mouth (15).According to injecting dissolve gas and eddy flow principle, sewage is pumped to jet ejectors continuously, the negative pressure of utilizing the liquid at high speed jet to cause sucks oxygen and microbial inoculum, and the gas, liquid, solid three-phase injection stream of coming out from injector enters reactor (5) with tangential manner.Because the blending effect of jet turbulent fluctuation and eddy flow, oxygen has been finished the process that gas phase shifts to liquid phase in moment (1/100S), and again according to the biliquid mass transfer theory, oxygen can form the even pure oxygen bubble of micron-scale, is dissolved in the mixed solution quickly and effectively.The oxygen transfer efficiency that this microbubble can reach is very high, thereby can keep 90% oxygen transfer efficiency in reactor (5), the outlet in reactor (5), and the dissolved oxygen in the mixed solution is generally up to 20mg/L.
2 compound bio filtrates
Main biofilter material (9), (10) that the utility model adopts are:
(1) chalk aragonite
Chalk is one of biochemical deposit thing, is made up of the calcite matter chip of calcite particle and algae, mollusk and ball algae, and yellowish-white chromaticness is crisp and light, and structure is single.Aragonite is the dimorphism variant of calcite, and this filtrate appearance is similar to diatomite, and a lot of bubbles are arranged, and has huge surface-area and voidage.
(2) bioactivation coal
This is the utility model with the porous matter coal of coal powder through forming after the biochemical treatment, and it can optionally allow friendly microorganism implantation and breeding.
(3) active lignocellulose
Active lignocellulose adopts needlebush to process, and remaining by extracting poly-pentose, lignin, protein, pectin etc. is lignocellulose, and this Mierocrystalline cellulose forms the porous air gap structure, is very suitable for implantation and the acting of friendly microorganism.
(4) titanium oxide
This filter material is present in the natural crystal, and its top layer that is laid on the biological filter both can be used as the artificial sidewalk of green land, can absorb the organic pollutant in the ultraviolet light degradation sewage again, can strengthen the sewage disposal function in filter tank.
3 biological filters
Biological filter in the utility model (9), (10) are the rectangle flat flow, it by one wide for 2-3M, be that the reinforced concrete soil box of 30-100M constitutes for 1-1.5M, length deeply, can be built in ground or underground, be provided with gas distribution pipe (16) at the bottom of the pond, the upper strata covers multiple composite filtering material (9), (10), and mixed solution flows to the other end, the biological oxidation of (9), (10) through the filter tank in the advection mode from the end in pond, CODcr place to go rate reaches 70%, and the NH3-N clearance reaches 60%.
4 circular oxygenation devices
This aerator (13) is made up of liquid oxygen storage tank, oxygen evaporator, pressure transmitter and control valve, pump (12) and pipeline etc.
Can make the utilization ratio of oxygen reach 90% after adopting this device, compare with air aeration, if processing efficiency is identical, the aeration tank volume can dwindle 1/3rd, and the mixed solution dissolved oxygen concentration can reach 6-12mg/L.
The utility model is owing to adopted complex biological filter (9), (10) structure and pure oxygen jet Aeration Technology and Its, so can improve the self-purification capacity of river greatly, the road Pollution abatement of centering river and to sanitary sewage and manure of livestock and poultry urine sewage disposal all has unusual effect, it is better to remove the ammonia nitrogen effect.Equipment is simple, and cost of investment is lower than existing sewage treatment facility, has social benefit and economic benefit widely.
Shown in Figure 1 is pure oxygen-jet-compound bio film sewage treatment device structure iron.
Below in conjunction with Fig. 1 narrate the utility model in Suzhou River tributary, Shanghai City-just like the embodiment of port river sewage treatment project experimental section:
Sewage is pressed into mixed flow biochemical reactor (5) from intake (1) through vacuum pump (2), the ingress sucks bacterium liquid (3) and air (4) with ejector, mixed solution enters reactor (5) with tangential high speed, and generation eddy flow, enter settling tank (8) and complex biological filter (9), (10) through the blending of fierceness and turbulent flow back by rising pipe (6), pass composite filtering material layer (9), (10) arrival settling tank (11).Centre and end in the filter tank carry out partial reflux with circular oxygenation device (13), are provided with gas distribution pipe (16) below the filter tank, and tail water is discharged by settling tank (11) post precipitation, and settling tank mud is discharged from mud discharging mouth (15) through sludge pipe (7).Air that enters and sewage ratio are 16 to 1, and mixed solution catalytic oxidation time in the filter tank is 1.5 hours.
