Description
Affiliated technical field:
The present invention relates to be used to carry out the environmental protection equipment technical field of sewage disposal, be specifically related to a kind of integrated film bio-reactor.
Background technology:
In today that the natural fresh water resource has day by day frequently been broken out by abundant exploitation, natural disaster; lack of water has been lived to the economy in numerous cities, countries in the world and citizen and has been constituted very serious threat; the lack of water crisis has been the reality that we face, and an important channel that solves the urban water shortage problem should be that municipal effluent is become the Urban water supply water source.Municipal effluent can get nearby, and steady sources is collected easily, is reliable and stable resource of water supply, and it can be mainly as municipal administration greening, landscape water and process water reuse after purifying.The sewage purification regeneration techniques is crucial in municipal effluent regeneration engineering.But existing technology is still traditional " the one-level anaerobic treatment " of having continued to use many years and reaches " secondary aerobic treatment " water treatment technology, it need be provided with two bigger big ponds of floor space and carry out sewage disposal, along with the requirement of the purifying treatment of current high turbidity and high-concentration sewage, the water outlet after original second-stage treatment can not have been satisfied the water quality requirement of city to the water reuse.For this reason, new technology is further additional " three-stage filtration adsorption treatment " equipment on existing equipment, promptly increases a separate tank again, so that improve effluent characteristics.Three grades of water processing establishments like this exist bulky complex on the structure, floor space is big, and investment and working cost are very expensive simultaneously, and the unsettled weak point of relatively poor, the middle quality of treatment effect.
Summary of the invention:
The purpose of this invention is to provide a kind of integrated film bio-reactor, big to overcome bulky complex, floor space that existing sewage disposal device exists, investment and working cost costliness, and the unsettled shortcoming of relatively poor, the middle quality of treatment effect.
For overcoming the shortcoming of prior art, technical solution of the present invention is, a kind of integrated film bio-reactor, comprise that the bottom is provided with the hydrolysis chamber 6 of water-in, in hydrolysis chamber 6, be provided with biologic packing material 2, its special character is: also comprise the reaction chamber 10 of being separated by with dividing plate 8, be provided with the filtration guide channel between described hydrolysis chamber 6 and the reaction chamber 10, this end that filters guide channel is communicated with the top in hydrolysis chamber 6, connection place is provided with filter member, the other end is communicated with the bottom of reaction chamber 10, and described reaction chamber 10 inside are provided with hollow fiber film assembly 5, and the bottom is provided with active sludge aerating apparatus 4.
Dividing plate 8 tops that are provided with between said hydrolyzed chamber 6 and the reaction chamber 10 are provided with flow-guiding mouth, and this flow-guiding mouth is connected with the filtration guide channel, and flow-guiding mouth is provided with grid 7.The area of flow-guiding mouth is little, and the grid 7 on it also is convenient to clean, change as filter member.
Above-mentioned filtration guide channel is the pipe connecting that is arranged in the reaction chamber 10, and an end of this pipe connecting is communicated with flow-guiding mouth on the dividing plate 8, and the other end is arranged at the bottom of reaction chamber 10.Like this water (flow) direction in reaction chamber 10 from bottom to top, abundant 5 duration of contact with hollow fiber film assembly, improved treatment effect.
Aforementioned barriers 8 is interlayers, and flow-guiding mouth is two, is arranged at the top of a side baffle wall in hydrolysis chamber 6 and the bottom of reaction chamber 10 1 side baffle wall respectively.
Also be provided with grid 7 on the flow-guiding mouth of above-mentioned reaction chamber 10 1 side baffle wall bottoms.To do further filtration.
Width such as above-mentioned flow-guiding mouth and dividing plate 8.The pending water-dispersion that enters reaction zone like this is more even.
What select for use in the above-mentioned hollow fiber film assembly 5 is the tubular fibre curtain type membrane.
Above-mentioned biologic packing material 2 is soft-filler, semi soft packing, elastic filler, multiaspect hollow ball or combined stuffing etc.Better with combined stuffing.
Compared with prior art, advantage of the present invention is:
1, simple in structure, floor space is little: the present invention is integrated in one three grades of original water treatments, has saved a large amount of water supply and sewerage pipelines and water pump, and is simple in structure; The integral structure floor space is little simultaneously, and its profile can design at random according to concrete place, and equipment layout is flexible and changeable, can realize the waste water on-the-spot disposal.
2, investment is little, running cost is low: handle 1 cubic metre of sewage power consumption 0.60-0.80kwh, amount to about 0.8 yuan of Renminbi.Only need just can obtain the effect of tertiary treatment level, realize the regeneration and the reuse of municipal effluent with construction investment that is equivalent to conventional I and II sewage work and the working cost that is lower than conventional second-stage treatment.
3, treatment effect is good: hydrolysis of the present invention chamber is one-level anaerobic treatment zone, when sewage passes packing layer from the hydrolytic tank bottom and upwards flows through, attached to the hydrolysis bacterium on the filler can be small molecules with macromolecular hydrolysis of organic matter in the sewage, become deliquescently with insoluble, create conditions for next step carries out aerobic treatment in reaction zone; In the simultaneously former tertiary treatment, the material that is not degraded in aerobic zone can be discharged, and in the present invention, because the effect of efficiently damming of film, realized that hydraulic detention time (HRT) and sludge retention time (STR) can control respectively, can not be by the organism of hollow-fibre membrane, difficult degradation thing etc. will be dammed in reaction chamber (reaction chamber promptly is equivalent to " secondary aerobic treatment " and " three-stage filtration adsorption treatment "), metabolism by microorganisms such as autotrophic bacteria and heterotrophic bacteriums finally makes it obtain degraded, and in reaction chamber, because having only middle water just discharges by hollow-fibre membrane, microorganisms such as other autotrophic bacteria and heterotrophic bacterium all are retained in the reaction chamber, microorganism concn height like this, can increase 5-10 doubly, make biochemical efficiency improve 15-35%.Experiment shows that through above-mentioned bi-level treatment, water meets national standard fully in the gained.
4, purification efficiency height: the present invention combines " the secondary aerobic treatment " and " three-stage filtration adsorption treatment " of sewage, finish this two treatment steps simultaneously, reduced the treatment time of one-level than tertiary treatment commonly used, through experiment, discovery can be saved the time over half, so purification efficiency improves greatly.
5, handle face width, middle quality is stable: it allows that the turbidity and the concentration range of disposing of sewage are extremely wide, experiment shows, use the present invention directly to suck the high-turbidity sewage of suspended substance (turbidity) up to 500 mg/litre to 5000 mg/litre, the suspended substance (turbidity) of handling the back water outlet is lower than 3 mg/litre (degree); Use the present invention directly to suck the high concentration organic sewage that CODcr is 200 mg/litre to 800 mg/litre, handle back water outlet CODcr and can reduce to below 40 mg/litre, effluent characteristics is stable.
6, long service life: in the entire structure, having only hollow-fibre membrane is easily-consumed products, and the film easy cleaning, be more than 3 years its work-ing life.
7, adopt intelligent PLC control, can realize whole-course automation control.
