Description
One, technical field
The utility model belongs to environmental technology field, particularly a kind of bisphenol S wastewater treatment equipment.
Two, background technology
The chemical name of bisphenol S is 4, and 4 '-dihydroxyl disulfoxide has good heat-resisting, fast light and antioxidant property.Bisphenol S and dihydroxyphenyl propane similar performance, purposes is also similar, particularly can replace dihydroxyphenyl propane aspect polymerization, and the product thermostability after substituting is enhanced better mechanical property.The bisphenol S purposes is very extensive, and its applied research is also quite active.External having had produced tens thousand of tons bisphenol S factory per year, can estimate that domestic and international bisphenol S will develop at faster speed in the several years.Producing bisphenol S is at present both at home and abroad obtained by the phenol Direct Sulfonation.But the organic pollutant of big, the difficult for biological degradation of toxigenicity, biodegradability difference in process of production, comprise the organism (as p-hydroxybenzenyl sulfonate class material) that contains sulfonic acid group, the organic pollutant that contains other groups (as hydroxyl, carboxyl etc.) in addition makes the COD in the waste water be higher than 10000mg/L.Patent 200510019609.4 discloses the bisphenol that utilizes in the cyclodextrin quickening photodegradation processing trade effluent.But complicated component in the bisphenol S industrial wastewater, toxicity is big, difficult degradation, COD height, difficult.
Three, summary of the invention
Goal of the invention: the invention provides a kind of bisphenol S wastewater treatment equipment.This device can effectively reduce the COD of bisphenol S industrial wastewater.
Technical scheme: a kind of bisphenol S wastewater treatment equipment is characterized in that this device is made up of extraction cells and extractant regeneration unit; Extraction cells comprises extraction addition agent storage tank, bisphenol S waste water storage tank, mixed extractant storage tank, multi-stage counter current extraction tower and volume pump; The extractant regeneration unit comprises solvent regeneration tower, strippant storage tank, lift pump and volume pump; The outlet of extraction addition agent storage tank links to each other with the import of bisphenol S waste water storage tank, the extraction auxiliary agent enters into the amount of bisphenol S waste water storage tank and is controlled by first volume pump, the outlet of bisphenol S waste water storage tank links to each other with the upper inlet of multi-stage counter current extraction tower, bisphenol S waste water enters into the amount of extraction tower and is controlled by second volume pump, the outlet of mixed extractant storage tank links to each other with the lower inlet of multi-stage counter current extraction tower, and mixed extractant enters into the amount of multi-stage counter current extraction tower and is controlled by the 3rd volume pump, and the following outlet of multi-stage counter current extraction tower links to each other with the import in wastewater biochemical pond; The upper outlet of multi-stage counter current extraction tower links to each other with first upper inlet of solvent regeneration tower, the outlet of strippant storage tank links to each other with solvent regeneration tower second upper inlet, strippant enters into the amount of regenerator column and is controlled by the 4th volume pump, first time outlet of solvent regeneration tower links to each other with the import of mixed extractant storage tank, and mixed extractant enters into the mixed extractant storage tank from solvent regeneration tower and is finished by lift pump, and second time outlet of solvent regeneration tower links to each other with the import of product retrieving arrangement.
Counter-current extraction Tata inner bottom part is equipped with the support screen, supports on the screen filler is housed.
Beneficial effect: the invention provides a kind of bisphenol S wastewater treatment equipment.This device combines with the co-current regeneration method by counter-current extraction and handles bisphenol S waste water.Wherein extraction cells adopts counter-current extraction tower, and the little solution of proportion enters from the bottom of extraction tower, and heavy solution enters from the top of tower.The tower inner bottom part is equipped with the support screen, supports on the screen filler is housed, and drop is constantly produced break with coalescent again, and to promote the Surface Renewal of drop, thorough mixing effectively reduces COD in the waste water; Regeneration unit adopts chemical method, and the co-current regeneration solvent makes the solvent recycling.This device can effectively reduce COD in the waste water.
