Abstract
The utility model discloses a novel high-concentration chemical sewage treatment device which comprises a sedimentation basin, a filter, an ultrafiltration device, a membrane bioreactor, a reverse osmosis device and a chemical treatment tank. The utility model combines the advantages of a membrane treatment technology and a biological treatment technology in design. The ultrafiltration membrane bioreactor is fully utilized and can effectively adsorb organic toxicants. By adopting the biological treatment technology in the design, organic matters in the sewage can be deeply treated. By adopting the treatment method which combines the ultrafiltration membrane technology and the biochemical treatment technology, the quality of the treated water can satisfy the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002), the removal effect is good, the long-term operation is stable, the operation is simple, the maintenance is convenient and the like. Moreover, after a small amount of treated sewage is intensively collected, the sewage can be re-treated and reused and thereby the cyclic utilization of water resources can be realized.
Description
Technical field
The utility model belongs to the environmental protection industry (epi) sewage treatment area, is specifically related to a kind of novel high-concentration chemical industry sewage treatment unit.
Background technology
In the daily production of chemical enterprise, produce a large amount of and contain the chemical engineering sewage of the organic and inorganic composition of high density through regular meeting.Because chemical engineering sewage composition complexity, generally have characteristics such as Pollutant levels height, hazardous and noxious substances content height, nutritive substance are single, biodegradability difference, brought certain difficulty to sewage disposal.Chemical enterprise generally adopts biochemistry or materilization freatment method at present, and there is the processing cost height in this method, and the poor processing effect phenomenon is difficult to qualified discharge, and serious system has been limit the development of chemical enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of novel high-concentration chemical industry sewage treatment unit in order to overcome above-mentioned defective, to be primarily aimed at the characteristics of high-concentration chemical industry sewage, designing.
The technical solution of the utility model is as follows:
A kind of novel high-concentration chemical industry sewage treatment unit, this device comprises sedimentation basin, strainer, ultra-filtration equipment, membrane bioreactor, reverse osmosis unit and chemical advanced treatment groove, the water outlet of described sedimentation basin communicates with the water inlet of described strainer, the water outlet of described strainer communicates with the water inlet of described ultra-filtration equipment, the water outlet of described ultra-filtration equipment communicates with the water inlet of described membrane bioreactor, the water outlet of described membrane bioreactor communicates with the water inlet of described reverse osmosis unit, and the water outlet of described reverse osmosis unit communicates with the water inlet of described chemical advanced treatment groove.
The a small amount of waste water that produces after reverse osmosis unit is handled adopts in the chemical advanced treatment groove and carries out chemical treatment, and the middle water after the processing can directly return in the production line and use.
Described this device also comprises grid, and described grid is located on the water inlet of described sedimentation basin.
The water outlet of reverse osmosis unit communicates with described sedimentation basin, when the effluent quality after reverse-osmosis treated does not reach when requiring, this water outlet can be turned back to again to proceed in the sedimentation basin to handle.
The beneficial effects of the utility model have:
On design selection, organically combined the advantage of membrane technology and biologic treating technique, fully use ultrafiltration membrane bioreactor, organic toxicant can be carried out the characteristics of active adsorption, simultaneously at composition complexity in the chemical engineering sewage, the situation that inorganic organic pollutant is more adopts biologic treating technique, can make the organism in the sewage obtain biochemical treatment.By the processing mode that adopts ultrafiltration membrane technique and biochemical treatment to combine, can not only make water quality after treatment can reach town sewage processing emission standard (GB18918-2002), but also have characteristics such as removal effect is good, long-term operation is stable, simple to operate, easy to maintenance.Also can handle reuse again, thereby realize the recycle of water resources simultaneously after leaving a spot of sewage employing centralized collection after treatment.
Description of drawings
Fig. 1 is a kind of structured flowchart of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The structure of high-concentration chemical industry sewage treatment unit of the present utility model as shown in Figure 1, this device is followed successively by grid 1, sedimentation basin 2, strainer 3, ultra-filtration equipment 4, membrane bioreactor 5, reverse osmosis unit 6 along the flow direction for the treatment of water, is respectively direct water outlet and chemical treating tank 7 after the described reverse osmosis unit 6.Described grid 1 is located at the ingress of sedimentation basin 2, the water outlet of described sedimentation basin 2 communicates with the water inlet of strainer 3, the water outlet of described strainer 3 communicates with the water inlet of ultra-filtration equipment 4, the water outlet of described ultra-filtration equipment 4 communicates with the water inlet of membrane bioreactor 5, the water outlet of described membrane bioreactor 5 communicates with the water inlet of reverse osmosis unit 6, direct and the exterior of the treat effluent mouth of described reverse osmosis unit 6, the dense water water outlet of described reverse osmosis unit 6 communicates with the water inlet of chemical treating tank 7, and the water outlet of described chemical treating tank 7 communicates with chemical production line reuse water pipeline.
When handling the sewage that contains the high density inorganic pollutant, in lectotype selection, can adopt the membrane bioreactor of forming by ultra-filtration membrane 5, by continuous two sections use uf processing, handle through reverse osmosis unit again, thereby guarantee that final outflow water can reach (GB18918-2002) emission standard.The dense water that produces in the described reverse osmosis unit, by chemical treating tank collect carry out chemical treatment after, reach reuse.
Other undeclared part that the utility model relates to is same as the prior art.
