Abstract
The invention discloses a bath water recycling MBR technology, and belongs to the technical field of reclaimed water recycling. The technology comprises the following steps: (1) introducing bath wastewater into a regulation tank by going through gratings, and adding a pH adjuster to neutralize the wastewater; (2) introducing the neutral wastewater in the regulation tank to a filtering tank; (3) introducing the filtered wastewater into a flocculation tank, adding a flocculating agent, compressing the air, and pumping the water to a MBR reaction tank; (4) processing wastewater in the MBR reaction tank, and injecting the wastewater into a disinfecting tank to disinfect the wastewater; (5) obtaining purified water after disinfection. The provided technology can effectively prevent sludge expansion and foam generation in the MBR reaction tank, the continuity and efficiency of the technology are both improved, the quality of the processed bath water is stable and good, and the processed water is accord with the national drinking water standards, can be used as drinking water, and is safe and harmless to human body. Moreover, the operation management is convenient, and the automatic control can be easily achieved.
Description
Technical field
The invention belongs to technology of middle water recycle field, relate to a kind of washing-water reuse MBR technique particularly.
Background technology
Bath water consumption is large, pollution level is low, belongs to high grade reutilization water source.Today that, Treated sewage reusing extremely in short supply in water resources comes into one's own day by day, the reuse of bath water becomes an important topic.
Compared with many traditional treatment process, MBR have effluent quality high-quality stable, excess sludge production few, ammonia nitrogen and hardly degraded organic substance can be removed, be easy to carry out from traditional technology the advantage transformed.But its exist energy consumption high, easily there is the shortcoming that fouling membrane is made troubles to operational administrative, film cost is high, be necessary to carry out Improvement.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existed for prior art, provides a kind of washing-water reuse MBR technique, after treatment, not only can be used for circulation bathing, meet national hygiene standard for drinking water simultaneously.
To achieve these goals, the present invention is achieved by the following technical solutions:
A kind of washing-water reuse MBR technique, comprises the steps:
(1) bath wastewater enters equalizing tank through grid, adds pH adjusting agent, by the pH regulator of waste water to neutral;
(2) in equalizing tank, neutral waste water flows into filtering basin;
(3) the waste water after filtering flows into flocculation basin, adds flocculation agent, and pressurized air, water is evacuated to MBR reaction tank;
(4) waste water is after the process of MBR reaction tank, injects sterilization pool and carries out disinfection;
(5), after sterilization, become and purify waste water.
What install in described strainer pond is hair filter.
Described flocculation agent is Al
2o
3polymkeric substance.
Further, inorganic coagulant FeSO is added in flocculation agent
4.
Further, defoamer is dropped in described flocculation basin.
Installation of New Type submerged hybrid mbr in described MBR reaction tank, this bio-reactor main design parameters: the process water yield is 150m
3/ d, the mass concentration that hydraulic detention time (HRT) is 8h, MLSS is 5500mg/L, and volumetric loading (in CODCr) is 0.62-1.66kgCOD/(m
3d).
Further, the Partial cleansing water in described sterilization pool is sprayed above MBR reaction tank by the form of spray.
The invention has the beneficial effects as follows:
(1) the present invention adopts MBR reaction tank to be main purification process, by adding FeSO in advance
4with defoamer, the means that spray, increase sludge volume above MBR reaction tank effectively in control MBR reaction tank sludge bulking and foam occur;
(2) flocculating effect of the present invention is good, auxiliary flocculation agent FeSO
4price is low, reduces cost of sewage disposal, improves the persistence efficiency of technique;
(3) the bath water water conditioning of present invention process process is excellent, meets national hygiene standard for drinking water, can be used as tap water and uses, harmless to human-body safety.
(4) convenient operation and management, easily is automated control.
Accompanying drawing explanation
Fig. 1 is the schema of bath wastewater treatment process embodiment of the present invention.
Embodiment
Further the present invention is set forth by reference to the accompanying drawings, be not construed as limiting the invention.
Embodiment 1
Be illustrated in figure 1 the schema of bath wastewater treatment process embodiment of the present invention, the water technology of the present embodiment comprises the steps:
(1) bath wastewater enters equalizing tank through grid, adds pH adjusting agent, by the pH regulator of waste water to neutral
(2) in equalizing tank, neutral waste water flows into filtering basin;
(3) the waste water after filtering flows into flocculation basin, adds Al
2o
3polymkeric substance and FeSO
4, and pressurized air, add defoamer, water is evacuated to MBR reaction tank;
(4) waste water is after the process of MBR reaction tank, injects sterilization pool and carries out disinfection, above Partial cleansing water cycle spray MBR reaction tank;
(5), after sterilization, become and purify waste water, can be used to bathing or drink.
Following table is the water-quality guideline adopting waste water treatment process of the present invention:
| Project | CODCr(mgL -1) | BOD5(mgL -1) | SS(mgL -1) | LAS(mgL -1) | NH 3-N(mgL -1) |
| Bath wastewater | 250～450 | 150～250 | 200～400 | 10～20 | 20～30 |
| Purify waste water | 30～40 | 5～10 | 0～1 | 0.5～1.0 | 5～10 |
| Middle water quality standard | ≤50 | ≤10 | ≤10 | ≤1.0 | ≤20 |
As shown above, the waste water indices after bath wastewater treatment process of the present invention process is adopted all to meet and exceed water quality standard in country.
