Abstract
A solid dosage Fenton reagent is made of two main materials of stable percarbamide and dry river sand (iron ore), and added with water for preparing liquid Fenton reagent on site. The Fenton reagent has a high processing efficiency for waste water and exhaust gas so that the Fenton reagent is a highly effective treatment agent for waste water and exhaust gas, and resolves troubles and safety problems during storage, transportation and use course of large amount of hydrogen peroxide so that the solid dosage Fenton reagent is convenient for use.
Description
Technical field
The invention belongs to environmental protection, health field.
Background technology
The increase of mankind's activity, expanding economy, causes the deterioration of environment, the anxiety of resource.The harm that waste water and gas causes environment is more and more serious.A kind of high-level oxidation technology that development in recent years is got up----Fenton reagent oxidation technology becomes the study hotspot in Environmental Science and Engineering field, is widely used in the practice of all kinds of pollutant treatment.
The aqueous solution that classical Fenton reagent is made up of ferrous ion and hydrogen peroxide, as the high-level oxidation technology of pollutant treatment, it has following features:
1) great amount of hydroxy group free radical can be produced, these hydroxyl radical free radicals are very active, its oxidation capacity (2.8V) is only second to fluorine (2.87V), also more much higher than ozone (2.4V), and free radical reaction is chain reaction, speed of response is exceedingly fast, so the decomposing organic matter that can be exceedingly fast;
2) physical chemistry treating processes easily controls;
3) by hardly degraded organic substance, water and carbonic acid gas can be oxidized to;
4) can decomposing organic matter again can sterilizing, sterilization.
Classical Fenton reagent, because be main raw material with hydrogen peroxide, given storage, transport, is used and bring very burden, dangerous again, which has limited popularization and the use of Fenton reagent.
I is exactly to solve above-mentioned shortcoming, and invents a kind of Fenton reagent of solid dosage.
Summary of the invention
My mandate patent of invention----" compound dioxygen tablet and method for making thereof " (ZL01120267X), is in fact exactly manufacture Solid hydrogen peroxide, is the crystallisate of carboxamide and hydrogen peroxide, is percarbamide, and its molecular formula is CO (NH
2)
2h
2o
2, due to H
2o
2be cured, qualitative, security improves greatly, preferably resolve hydrogen peroxide store, transport, use in problem.So, the present invention is characterized in: employing dry stabilization of solid percarbamide is the Fenton reagent that main raw material manufactures solid dosage.Concrete method for making is as follows: first the two large main raw material solid hydrogen peroxides and reductibility catalyzer such as metallic ore etc. that manufacture Fenton reagent are separately packed; Make liquid Fenton reagent at the on-the-spot water of use in required ratio, now do existing use.
Concrete implementing measure
The present invention is further illustrated below in conjunction with embodiment.
The removal of embodiment 1 natural gas odorization agent tetramethylene sulfide loading-unloading vehicle discharge gas stink
Containing tetramethylene sulfide 75mg/m in discharge gas
3, make this discharge gas in PH=3 ~ 5, Fe2+ mass concentration be at 20mg/L, H
2o
2concentration bubbling in the Fenton reagent of 30% pass through, final exhaust is containing tetramethylene sulfide 5mg/m
3, clearance: (75-5)/75=93%.
Embodiment 2 solid Fenton reagent process high concentration phenol waste water
In mass ratio
the liquid Fenton reagent of proportioning preparation, remove the waste water of the 1000-10000mg/L processed containing benzene, PH=3, normal temperature, the clearance of benzene is more than 90%.
Produce 100 tons of solid Fenton pulvis per year and produce 10 tons of sprays pilot plant project feasibility reports per year
One, the purposes of product, market outlook and item purpose and meaning
From 1 day January in 2002, produce the enterprise of wood-based panel product (comprising medium density fibre board (MDF), high density fiberboard, shaving board, glued board, core-board, solid wooden compound floor etc.), must ten mandatory national standards such as the GB8580-2001 " in house decorative material wood-based plate and goods thereof Form aldehyde release limitation " that formulates of strict implement State General Administration for Quality Supervision.From 1 day July in 2002, market is suspended sale of the product not meeting these ten national standards.According in first quarter calendar year 2001 country's wood furniture, burst size of methanal exceedes 40% of former standard≤40mg/100g.And new standard specifies: the wood-based plate being directly used in upholstery, burst size of methanal is only≤9mg/100g.Weigh according to new standard, eligible has just remained little.
In China, due to the requirement in the shortage of the forest reserves and environment protection, industry of artificial boards also will have larger development.And the sizing agent that Wood-based Panel Production uses (urea-formaldehyde resin adhesive and Phenol aldehyde resin), in short duration can't completely by without aldehyde sizing agent replace.Such wood-based plate just must process, and therefore, artificial board formaldehyde treatment agent has the wide market requirement.
The rule of China's first monitor the situation environment pollution---" code for indoor environmental pollution control of civil building engineering " been has has been issued and implemented, and " the some suggestions about strengthening the management of construction work indoor environmental quality " that match with it are also put into effect simultaneously.The Con trolling index of this specification to the formaldehyde of construction work indoor, benzene, ammonia, total volatile organism (VTOC) equal size has also made strict regulation.Civil building engineering, decoration, fitting-out work must strictly observe these specifications from now on, violate must affixing the responsibility of regulation.Artificial board decorative disposes above-mentioned most of obnoxious flavour, generates water, CO2 and carbohydrate.Therefore, artificial board formaldehyde treatment agent can use as indoor air freshener.Artificial board formaldehyde treatment agent, once enter family, can bring you beyond thought effect.It is such that one respond well, is nontoxicly removed the evil, inexpensive daily necessities market is big well imagines.
At present, the sizing agent more than 70% that China's wood working uses makes urea-formaldehyde resin adhesive, and this sizing agent is mainly for the manufacture of wood-based plate and wood-based plate secondary processing.Wood-based plate is mainly used in manufacture and finishing, the decoration of furniture.In manufacture and fitting-up process, undisciplined health of people.Therefore production environment protection type urea formaldehyde resin is developing direction from now on.
Utilize formaldehyde to have the feature of reductibility, after resins synthesis and synthesis, add oxidisability improving agent just can reduce strong formaldehyde content, if add solid Fenton reagent, it decomposites H
2o
2and urea, H
2o
2oxidation of formaldehyde formic acid can be reduced strong formaldehyde content, urea and formaldehyde reaction generate urea-formaldehyde resin again simultaneously, and solid Fenton reagent is optimal urea-formaldehyde resin improving agent and formaldehyde-trapping agent thus.According to data introduction: additional proportion be 5% ~ 10% Sumstar 190 as improvement time, can be just that 0.2% ~ 0.5% (reduced rate is more than 90%) be down to by the urea-formaldehyde resin of 3% ~ 7% by free formaldehyde content.Change and do the meeting of solid Fenton reagent effect better.China's urea-formaldehyde resin in 2005 will reach 1,500,000 tons/year by inference, and annual just needs 5 ~ 100,000 tons of solid Fenton reagents are the formaldehyde treated agent of main raw material.
