Abstract
The invention relates to the technical field of industrial wastewater treatment process, in particular to an acetoacetanilide wastewater recycling process. Acetoacetanilide wastewater is firstly subjected to preliminary filtration and then is recycled by means of the adsorption action of resin; afterwards the resin is subjected to desorption treatment, and finally recycling is realized and waste is reduced. The treatment process is simple, operation and management are convenient, a device is simple and small in occupied area, and NDA-150 resin has a property of selectively adsorbing naphthalene type organic matters, is high in adsorption efficiency and easy for desorption regeneration. In a whole wastewater treatment process, any new pollutant is not introduced, and secondary pollution is not generated. The NDA-150 resin is high in acid and alkali resistant capacity, high in mechanical strength and good in temperature resistance and has the service life of at least 4 years.
Description
Technical field:
The present invention relates to technique for treating industrial wastewater technical field, be specifically related to two ethylbenzene amine wastewater recycling process.
Background technology:
Current sewage treatment process route: iron-carbon micro-electrolysis → Fenton → iron bed → UASB → aerobic → acidication → SBR
Existing utility running condition: survey aniline residue about 30mg/L (two ethylbenzene amine does not detect) after Fenton's reaction, anaerobic effluent aniline residue rises to more than 100mg/L, about outputted aerobic water COD2000mg/L, aerobic sludge amount is few, and aerobic system processing power is lost substantially, and anaerobic UASB column internals breaks down and cannot normally run, iron-carbon micro-electrolysis effect does not reach design requirements, it is too large that Fenton adds the dioxygen water yield, and working cost is too high, and enterprise cannot bear.
Summary of the invention:
The object of this invention is to provide two ethylbenzene amine wastewater recycling process, its treatment process is simple, and convenient operation manages, and device is simple, and floor space is little, and wherein NDA-150 resin has the organic performance of selective adsorption naphthalene system, and adsorption efficiency is high, and desorption and regeneration is easy.Do not introduce any new pollutent in wastewater treatment whole process, do not produce secondary pollution.NDA-150 resin acid and alkali-resistance ability is strong, and physical strength is high, and heat resistance is good, and its work-ing life reaches more than 4 years.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its recovery method:
1) filter
Under normal circumstances, the basic mechanical impurity of the alpha.-acetylacetanilide waste water given off from workshop and suspended substance, for ensureing normally carrying out of follow-up resin absorption section, setting up quartz filter to filter herein and checking on.
2) resin absorption
2.1) adsorption mechanism
When absorption refers to that fluid contacts with porosu solid material, one or more diffusion of components in fluid to porous mass outside surface and micropore internal surface, and are attracted to the process on these surfaces by intermolecular Van der Waals force.If the absorption of sorbent material to component a certain in fluid has selectivity, so this component will by adsorption and enrichment on resin, thus realizes and being separated of other component in fluid.Polymer absorbant (polymeric adsorbent), owing to having adjustable pore structure and surface chemical structure, thus by the difference of sieving action and intermolecular reactive force power, realizes organic enrichment, separation and recovery in waste water.
Due to the action principle of traditional functional polymer sorbent material, be confined to single ion-exchange or adsorption, this is effective to the simple ionic compound of separation or low water solubility, low polar organic matter, but to containing the organic high-concentration organic chemical wastewater of highly water-soluble, as alpha.-acetylacetanilide factory effluent, only voucher one ion-exchange or adsorption are difficult to obtain desirable effect, and processing efficiency is low, weak effect.Research finds compared to macroporous adsorbent resin, there is the super high cross-linked adsorbing resin enriching microvoid structure, be more suitable for the absorption to alpha.-acetylacetanilide, this is because when the aperture of sorbent material is the several times of adsorption molecule diameter, the absorption potential energy of sorbent material is stronger, larger with the reactive force of adsorbate.
NDA-150 type macroporous adsorbent resin selected by the improvement of alpha.-acetylacetanilide factory effluent is the high molecular polymer with tridimensional network of a kind of high-crosslinking-degree, high-specific surface area, the specific surface area utilizing polymeric adsorbent higher and excellent pore structure, by intermolecular Van der Waals force, the useful matter alpha.-acetylacetanilide in waste water is adsorbed onto resin surface, thus realizes waste water control and resource reclaim.
2.2) absorbing process

Adsorption temp normal temperature
Absorption flow 8.5m
3/ h
Adsorption treatment amount 9m
3/ batch
3) resin desorption
For by the saturated resin of Adsorption of Organic, renovation process can adopt the inorganic desorbing agents such as soda acid, also organic solvent can be adopted to carry out wash-out as desorbing agent to resin, then organic separation is realized by isolation technique such as rectifying, or desorption liquid turns back to reduce consumption in production technique, improve yield.This items selection methyl alcohol, as desorbing agent, adopts the method for gradient elution, effectively by clean for the organism wash-out being adsorbed on resin surface, can realize regeneration and the Reusability of resin.Desorption conditions is:
Desorbing agent 6m
395% industrial methanol+18m
