Description

A kind of synergy of Fenton systems and discharge-reducing method
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of synergy of Fenton systems and discharge-reducing method.
Background technology
In recent years, China's water use model is extensive, and water pollution is serious, and water-use efficiency is low, causes the contradiction of supply and demand for the water resource increasingly It is prominent.According to statistics, in China's sewage, wastewater discharge, urban domestic wastewater accounts for 40%, and industrial organic waste water is accounted for 60%, it is seen that industrial organic waste water discharge capacity Yi Zhan China discharge of wastewater it is a greater part of, and the recycling of industrial wastewater to section About water resource, environmental protection, realize that sustainable development is extremely important.With the fast development of China's economy, work Industry production waste water shows water quality complexity, difficult for biological degradation, high concentration and highly toxic feature, and traditional biochemical method is very Its processing up to standard is caused serious water resource pollution by hardly possible.The processing of industrial organic waste water has become water pollution control neck The difficult point in domain.
High-level oxidation technology (AOPs) be grow up 1980s can using the physics such as light, sound, electricity, magnetic and The high activity intermediate OH that chemical process is produced, quick mineralising pollutant or improves its biodegradability, with it is applied widely, A kind of wastewater processing technology for the characteristics of reaction rate is fast, oxidability is strong, in processing printing and dyeing, agricultural chemicals, pharmacy waste water and rubbish There is very big advantage in terms of the high toxicities such as percolate, used water difficult to degradate.AOPs has turned into industrial organic waste water and has handled neck at present The study hotspot in domain.
Fenton oxidation technology is a kind of classical high-level oxidation technology, is most economical, maximally effective oxygen generally acknowledged at present One of change technology.H.J.H.Fenton is reported point out H first within 18942O2In Fe2+Have oxidation many under the catalytic action of ion Plant the ability of organic matter.H2O2With Fe2+The combination of ion is Fenton reagent, wherein Fe2+Ion is urged primarily as homogeneity Agent, and H2O2Then play oxidation.Typically in acid condition, H2O2In Fe2+Catalysis under generate OH, OH oxidation Current potential is 2.8V, is only second to the 2.85 of fluorine, so it can be with the organic matter RH reaction generation organic matter free radicals in waste water (R), R is further oxided, and final product is CO2And H2O, so that organic matter is fully degraded.So Fenton is tried Agent has extremely strong catalysis oxidation ability, be particularly suitable for use in some refractory reasons or to biological virose heterocycle pharmacy waste water In processing, current Fenton reagent also increasingly gets more and more people's extensive concerning.
Fenton catalytic oxidation technologies have the advantages that efficiently quick, equipment is simple, technical requirements are not high, but it reacts PH scopes it is smaller, its value is generally 2-4, reacts the Fe produced3+Although faint catalytic action can be played during the course of the reaction, may be used also Generation is with flocculation, the Fe (OH) of absorption property under certain pH value3Colloid, can have and go part harmful substance in water removal Effect, but a large amount of iron cements can be produced, in addition with H2O2The low problem of utilization rate, these shortcomings all limit Fenton catalysis Oxidation system efficiency, so wanting idea to try to improve Fenton catalytic oxidation system efficiency.Improve H2O2Utilization rate, widen reaction PH, reducing the quantity of setting sludge, trace to source can be from Fenton reagent Fe2+Ion and H2O2These two aspects is started with.
First, from Fe2+Aspect improves efficiency, and reducing iron cement amount, we will reduce Fe by every means2+Dissolution or allow Fe3+With Fe2+Circulation:For reducing Fe2+Dissolution can start with from heterogeneous catalysis, at present for heterogeneous catalysis Research is relatively goed deep into;For Fe3+With Fe2+Circulation, can be added into Fenton systems complexing agent for example oxalic acid, citric acid, The carboxylic-acid substances such as ethanedioic acid disuccinic acid and Fe3+Complex compound is formed, on the one hand can reduce the reduction potential of iron, on the other hand Fe can be produced under illumination condition2+Promote Fe3+With Fe2+Circulation, can additionally widen reaction pH, at present on iron complex The research of this block is relatively goed deep into.For promoting Fe3+With Fe2+Circulation, first can be added less than theoretical amount into reaction system Catalyst ferrous ion and oxidants hydrogen peroxide, when organic wastewater degraded rate reaches maximum into Fenton systems in proportion Repeatedly circulation adds reducing agent, and such as Zero-valent Iron, hydroxylamine hydrochloride, ascorbic acid, ammonium sulfite reducing agent have stronger reduction Ability, can be good at Fe3+It is reduced to Fe2+, promote Fe3+With Fe2+Circulation, can reduce sludge yield, and can promote to produce More hydroxyl radical free radicals, so as to improve reaction efficiency, reducing agent is introduced in addition can also widen the pH of reaction, Fenton systems The middle research for introducing reducing agent has caused the deep concern of brainstrust now, merits our study.
Second, Fenton system can not only use the most frequently used oxidant liquid hydrogen peroxide, can also use in recent years To be increasingly becoming the solid hydrogen peroxide percarbonate (SODIUM PERCARBONATE/potassium percarbonate) of focus.Solid hydrogen peroxide was being used Stable in journey, easily storage transport, cost is relatively low, and applicable scope is wider, and it is nontoxic, profit for microorganism that catabolite, which is, In further biodegradation, the product of oxidation is generally CO2、H2O, carbonate, are all spontaneous materials, so in recent years Also study hotspot is turned into.
The content of the invention
The technical problem of solution:Present invention aim to address existing Fenton systems using pH scopes it is smaller, can produce A large amount of iron cement, H2O2There is provided a kind of synergy of Fenton systems and discharge-reducing method for the low technical problem of utilization rate.This method is utilized The ferric iron produced in the reducing agents such as Zero-valent Iron, hydroxylamine hydrochloride, ammonium sulfite reduction Fenton systems, promotes ferric iron and divalence The circulation of iron, increases hydroxyl radical free radical yield, improves the efficiency that Fenton systems handle organic wastewater, reduces sludge yield.
