Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to a kind of combination for Wastewater from Organic Chemistry Laboratory processing
Device.
Background technique
The chemical waste that Organic Chemistry Laboratory generates is mainly organic liquid waste, these organic liquid wastes are toxic a bit
, such as human immune system can be destroyed containing the biggish dimethylbenzene of concentration, chloroform, cause function of human body to lack of proper care.Some organic wastes
Liquid because its containing the biggish spent acid of concentration, salkali waste and have very strong corrosivity.It, not only can be right if arbitrarily discharging these waste liquids
Environment and human health cause to seriously threaten, and can generate undesirable exemplary role to student.Compared with industrial wastewater, have
Machine laboratory waste water is more with type, the characteristics such as chemical reaction easily occur.Just because of these characteristics, bring not to subsequent processing
Few trouble.It obviously cannot meet the needs using traditional method for treating water.
Waste water can be improved using traditional method for treating water (such as physical method, chemical method, bioanalysis) to a certain extent
Water quality situation, but have respective insufficient or disadvantage.Wherein, physical method is arranged impurity in the way of absorption, precipitating or barrier etc.
Except outside.As classical activated carbon adsorption can effective purifying water body, but as the extension charcoal adsorption capacity of time will constantly weaken,
Periodically it need to be cleaned and be replaced, and it can not aoxidize organic pollutant degradation, thus may cause phase transfer, make to ask
Topic further deteriorates.Chemical method includes oxidation processes, neutralisation treatment, coagulating treatment etc., possesses and fast and effeciently removes pollutant
Ability, however be likely to occur that recycling is difficult, is easy to generate secondary pollution problems in actual operation.In contrast, raw
Object method becomes one of water treatment technology most popular at present with its economy and green environmental protection, but works as in waste water and there is difficult drop
When solving organic matter or pollutant containing bio-toxicity, solely it is difficult to obtain ideal degradation effect using the Biochemical method waste water
Fruit.And biological treatment effect promotion is difficult to grasp and uncertainty is very high.
Macroporous absorbent resin is a kind of preparation for being free of cation exchange groups and having macroporous structure, is had good
Macroreticular structure and biggish specific surface area, can be optionally through organic in the mode adsorption aqueous solution of physical absorption
Object is the novel organic polymer adsorbent to grow up the 1960s.Macroporous absorbent resin be by physical absorption from
Organic substance is selectively adsorbed in solution, thereby achieving the purpose of separation and purification.Its stable in physicochemical property, insoluble in acid, alkali
And organic solvent, it is selectively good to organic matter, it is not influenced by existing for inorganic salts and strong ion, low molecular compound, in water
It is expanded with adsorbable solvent in organic solvent.Macroporous adsorption resin technology technological operation is easy, and difficulty is little, and resin can
Be used for multiple times, also renewable Reusability, cost be not it is very high, equipment is simpler, and this technique can save largely
The expenses such as energy consumption, auxiliary material, packaging material, storage.
Iron-carbon micro-electrolysis is using Principles of Metal Erosion come degradation of contaminant, forms primary battery to waste water by metal erosion
A kind of technique handled, also known as internal electrolysis, Filtration with Iron Filings etc..The electric field action formed between iron carbon electrode is in useless
Charged colloidal particles in water promote these colloidal particle directional migrations, to promote the enrichment of Pollutants in Wastewater matter and go
It removes.Iron filings can adsorb various metals ion, so that metal ion is replaced as simple substance and is removed, carbon particulate and work in iron filings
Property charcoal has stronger suction-operated to metal ion.And cast iron has absorption as a kind of porous mass as activated carbon
Ability can adsorb the organic matter in water.
Take boron-doped diamond thin-film electrode (BDD) as the cleaning equipment of core, is used for electrochemical process water as a new generation
The electrode material of processing, compared with the traditional materials such as noble metal and ti-based coating electrode (DSA), BDD electrode has best sun
Pole oxidability, widest potential window and highest current density.The sp of diamond-stable3Structure make it have it is corrosion-resistant,
The good characteristics such as high temperature resistant, anti-oxidant and resistance tocrocking.Under electric field action, BDD electrode surface can successively generate tool
The free state hydroxy radical OH(standard oxidizing potential for having superpower oxidisability is 2.80V, close to the 2.87V of simple substance fluorine gas), peroxide
Free radical HO2, ozone O3With hydrogen peroxide H2O2Equal oxide species, while being reacted with waste liquid, also to various microorganisms, packet
Including bacterium and virus has strong killing effect.
Photocatalysis technology principle is to purify dirt based on the redox ability that photochemical catalyst has under ultraviolet light irradiation
Contaminate object.Have many advantages, such as novelty, high efficiency, to waste water non-selectivity, is particularly suitable for the degradation of unsaturated hydrocarbon, and react item
Part is also relatively milder, without secondary pollution, has a good application prospect.When there are semiconductor powder catalyst in organic wastewater
When, after the ultraviolet light of some strength, a certain amount of, diversified forms active oxygens and freedom just can be generated in system
Base, due to these reactive oxygen species and free radicals oxidizing potential with higher, so can act on organic matter and make its degradation, in turn
Mineralising is water and carbon dioxide, to achieve the purpose that improvement.Photocatalytic process using semiconductor material as photochemical catalyst,
It can be reacted under normal temperature and pressure.More important is contaminant degradation can be nontoxic inorganic molecules by photocatalysis technology
Substance such as CO2、H2O and various corresponding inorganic ions and realize it is innoxious, for administer water pollution provide one it is new, have it is latent
The approach of power.
Due to Lab Organic Wastewater is relatively complicated, discharge amount is small, the discharge period is indefinite, instantaneous concentration of emission compared with
It is high, it is impossible to all contaminants only to be removed totally with a kind of method.Therefore processing Lab Organic Wastewater generally requires
Several method combination, can be only achieved preferable treatment effect.This experiment is novel to plan physical absorption (macroreticular resin), the micro- electricity of iron carbon
Solution technology, chemical degradation technology and photocatalysis technology are combined, and establish the cleaning module of high efficient and reliable.
Summary of the invention
1. technical problem to be solved:
Above-mentioned existing in order to solve the problems, such as, the present invention provides one kind and can handle Wastewater from Organic Chemistry Laboratory
And reach the requirement of energy direct emission.Traditional method for treating water and iron-carbon micro-electrolysis technology, chemistry are dropped in the method
Solution technology and photocatalysis technology are combined, and provide a kind of easy to operate, clean and environmental protection, efficiently scientific Organic Chemistry Laboratory
Wastewater treatment equipment.
