Change organosilicon-demulsifying flocculant and its application of Top of Vacuum Tower oil-polluted water.
Background technology
The emulsification sewage quantity that is discharged with atmospheric and vacuum distillation unit in petroleum refining process is increasing, such containing greasy dirt
Water water-oil emulsion is difficult to be layered, and generally has that oil content is big, complicated component（Containing more alkane, halogenated hydrocarbons, aromatic hydrocarbon ethers
With mercaptan etc.）, intractability high the features such as.Cause biochemical treatment apparatus treatment effeciency low, if it is exceeded not only to discharge water oil content
Environmental pollution can be caused, while will also result in the loss of a large amount of oil products.
Domestic refinery(waste) water adopts coagulation（Oil removal, air supporting, breakdown of emulsion etc.）, two stage biological process（Activated sludge, biochemistry
Aeration, biological film process etc.）With three-level advanced treating（UF membrane, absorption, catalysis oxidation etc.）, generally refine only with two stages for the treatment of
Oily factory's sewage wants qualified discharge, therefore oil content proposes higher standard in reduction water effective to coagulation.And chemical demulsification
Method is studied more universal as the effective means for reducing oil content in water in refinery oily waste water treatment.And traditional demulsifier,
Flocculant and its compounded combination are difficult to obtain preferable deoiling effect, and if can be produced using inorganic flocculating agent a certain amount of
Floccule is precipitated, on the one hand meeting contaminated product, is on the other hand produced sludge and is caused secondary pollution.Therefore, research refinery contains greasy dirt
The more efficiently chemical demulsification technique of water has larger using value.
Content of the invention
For overcoming the deficiencies in the prior art, the invention aims to providing a kind of for coagulation refinery vacuum tower
Organosilicon-the demulsifying flocculant of top oil-polluted water.
