Description
Technical field
The invention belongs to technical field of sewage, particularly a kind of bisphenol S high-concentration waste water
Pretreatment technology.
Background technology
Bisphenol S production technique adopts to carry out sulfonation condensation reaction little over the phenol measured and the vitriol oil under sym-trimethylbenzene solvent action, carries out recrystallization by methanol solution as solvent; Can produce a large amount of high-concentration waste waters in production process, containing phenol, sym-trimethylbenzene, methyl alcohol and a small amount of bisphenol S and impurity thereof in high-concentration waste water, COD is up between 10-15 ten thousand ppm, and phenol is sometimes up to 30000-50000ppm; Such high-concentration waste water can cause in sewage treatment process cannot complete process, intractability is large, processing costs is large, especially the phenolic wastewater of high density cannot be accomplished to decompose qualified discharge completely at all in later stage sewage process, therefore face high-concentration waste water, especially the wastewater containing phenol of high density carries out problem of pretreatment.
At present, wastewater containing phenol roughly has following several method: extraction process, vaporizing extract process, biochemical treatment process, oxidation style, liquid film extraction facture and absorption method etc.
Extraction treatment method adds a kind of with water objectionable intermingling but pollutent good solvent (extraction agent) in waste water, and make it fully mix with waste water, the most of pollutent in waste water is transferred in extraction agent; Then extraction agent, waste water can be made to be purified, then be separated with pollutent wherein by extraction agent, make extractant regeneration, recycle, the pollutent of separation is reclaimed.What current use was more has N-503, TBP and TOPO etc., wherein N-503 is a kind of the most frequently used High-Efficiency Phenol-Degradation extraction agent, but the content of phenol in waster after extraction does not still meet discharging standards, and secondary pollution is brought containing the extraction agent of trace in waste water, and the bad meeting of extraction agent layering causes loss, general extraction agent cost is higher.
Vaporizing extract process is that waste water directly contacts with water vapour, volatile matter is wherein diffused in gas phase according to a certain percentage, thus reaches the object of separating contaminants from waste water; Vaporizing extract process is commonly used to the material such as volatile phenol, formaldehyde, ammonia removed in waste water, but still has the remaining phenol of higher trial in waste water after stripping, and observable index is larger.
Wastewater biochemical method is exactly utilize the metabolism of microorganism that the organism in waste water is converted into the process of simple inorganics, and the concentration in waste water, when 50mg/L-500mg/L, is applicable to biochemical process process, and excessive concentration can make microbial death.
Chemical oxidizing agent is added in waste water, phenol is decomposed, also makes the reducing substances in water oxidized simultaneously, but this method is applicable to containing the wastewater treatment of phenol amount lower than 1000mg/L, conventional chemical oxidizing agent has ozone, potassium permanganate, hydrogen peroxide etc., but processing costs is higher.
Liquid film extraction is a kind of new extraction separating method, and quite obvious for low concentration wastewater treatment effect, clearance reaches more than 99%, has good treatment effect, have good development prospect for the waste water containing nitrophenol.
Absorption method is the process that a kind of material is attached on another kind of material surface, and it can occur between solution-air, gas-solid, liquid-solid two-phase.In the treatment of waste water, absorption utilizes porous solid sorbent material to have one or more pollutents in surface adsorption waste water, reaches the process of purification of waste water.The solid adsorbent extensively taked at present has gac, diatomite, sulphonated coal etc., but these adsorbent less effective, the scope of application is also narrower.
Summary of the invention
The technical problem to be solved in the present invention is to provide good two of the low and treatment effect of a kind of cost
Phenol S High concentration wastewater pretreatment technology.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of bisphenol S High concentration wastewater pretreatment technology, and its innovative point is: described technique concrete steps are as follows:
(1) macroporous resin column is prepared;
(2) impure for bisphenol S waste water is placed in dropping funnel, at room temperature slowly instills, make in its macroporous resin column passing through to prepare, cross post liquid and detected by Quick testing instrument;
(3) by after saturated for impure for bisphenol S waste water multiple adsorb in resin, then dropping wash-out is carried out with the solution of amount of resin 2 times amount;
(4) wash-out is again with the clear water elute soln with amount after completing, and then gained elutriant carries out aftertreatment again, reclaims phenol.
Further, the macroporous resin column in described step (1) or step (2) is the one in DA201-C type resin column, NKA-2 type resin column or H-103 type resin column.
Further, the solution in described step (3) or step (4) is the one in methyl alcohol or 5%NaOH.
The invention has the advantages that: bisphenol S High concentration wastewater pretreatment technology of the present invention, macroporous resin is adopted to carry out adsorption treatment to waste water, its macroporous resin used have advantages of good adsorption effect, desorption and regeneration easily, stable performance, applied widely, practicality good, can realize the features such as comprehensive utilization, and then makes the cost of wastewater treatment low and treatment effect good.
