Description
Technical field
The invention belongs to sewage disposal technology, a kind of high efficiency composition that contains fluorescence waste water that is applicable to process is provided especiallyFlocculant and sewage water treatment method and supporting sewage disposal device.
Background technology
Fluorescent penetrant, as tracer, is widely used in the detection of aircraft industry precision parts. After detection zeroIn the waste water that parts produce in the time cleaning, contain a large amount of paraffin oils, ethoxy alcohol, tributoxyethyl phosphate, secondary alcohol ethoxyBase, surface dispersant, fluorescer and various additive, composition is very complicated. The sewage petroleum class that contains above-mentioned substance,CODcr equal size is higher, and being difficult for carrying out later stage sewage disposal, particularly breakdown of emulsion problem has become the large of fluorescence wastewater treatmentA difficult problem.
At present, the fluorescent penetrant that aircraft industry aircraft manufacturing generally adopts magnetic flux company of the U.S. to produce, magnetic flux company is carriedThe fluorescence waste water treatment process of confession is very complicated, needs heating, oxidation, high-speed separation, adjust pH, need to add respectively 6 kinds of medicaments,Operational administrative bothers very much, is difficult to the effect that reaches desirable, and the equipment of installation can not normally move into " ornaments ". Domestic productionThe waste water that produces of fluorescent penetrant, more there is no ripe treating method.
Particularly in recent years, along with the fast development of auto industry, automobile core component quality was badly in need of improving, some automobilesFluoroscopic examination production line is also being installed by manufacturing firm, and Changchun oneself have 3 to come into operation. Due to fluorescence wastewater treatment difficulty, costHeight, is difficult to qualified discharge, and because environmental protection supervision is strict, sewage produces unit and sewage can only be entrusted sewage treatment plant to concentrate placeReason. But in the face of hc effluent, particularly contain the sewage of the contour petroleum-type of fluorescer and CODcr, sewage treatment plant is not equallyCan effectively process, even section processes factory, for sewage qualified discharge, takes the mode of dilution discharge to escape supervision. Above-mentioned behaviorNot only bad for the sound development of enterprise, heavier is is irreversible to the destruction of environment, the particularly reproducibility of high-loadOrganic discharge wantonly.
Therefore, fluorescence waste water has become a large hidden danger of environmental pollution. Invent a kind of simple and practical, be convenient to management new materialReplace traditional handicraft, become an active demand of fluorescence wastewater treatment.
Summary of the invention
The object of the present invention is to provide a kind of be applicable to process the high efficiency composition flocculant and the dirt that contain fluorescence waste waterMethod for treating water.
The present invention specifically provides a kind of high efficiency composition flocculant, for sewage disposal, comprises the thing of following mass fractionMatter composition: organic polymer demulsifier, 5 ~ 25%; Inorganic flocculating agent, 15 ~ 55%; Organic quick-acting flocculation aid, 0.5 ~ 10%; NothingMachine micro mist oil absorbent, 25 ~ 60%.
