Description
Technical field
The present invention relates to a kind of treatment process of organic waste water, belong to technical field of sewage in the environment protection.
Background technology
The quantity discharged of various organic waste waters increases year by year, brings huge challenge to water environment protection.The combination of treatment process general using biological process, physics method and chemical method and two or more methods of conventional organic waste water, but biological treatment such as activated sludge process also face the recovery and the ultimate disposal problem of active sludge simultaneously because of organic pollutant causes treatment of organic matters of organic inefficiency in the waste water to the toxic action of microorganism.Physics method such as absorption method make organic molecule be adsorbed on its surface or allow the filter bed of organic waste water by being made of sorbent particles, thereby reach the purpose of purification of organic waste water, yet sorbent material cost height, non-renewable, loading capacity is limited, general by modification to sorbent material, mention the absorption property and the work-ing life of sorbent material.Chemical method such as Coagulation Method, oxidation style, the coagulation rule need add a large amount of coagulating agent, the many and dehydration difficulty of body refuse amount, present research direction is the coagulating agent of development of new.Traditional homogeneous phase Fenton method is that ferrous ion and hydrogen peroxide react the extremely strong HO free radical of generation oxidisability under acidic conditions, HO has higher electronegativity and stronger electron affinity, can capture the H atom in the organic pollutant molecule, fill unsaturated carbon-to-carbon double bond or triple bond, show as strong oxidizing property, thereby oxidative degradation organic pollutant, even be harmless inorganicss such as carbonic acid gas, water and mineral salt with the organic pollutant oxygenolysis up hill and dale, can not produce new pollution, there is the problem of reaction back separation difficulty in the Fenton reaction.Therefore, most of at present research is devoted to develop the heterogeneous Fenton catalyzer of synthesizing efficient practicality.
The mineral rock that the magma condensation that sprays when volcanics is volcanic eruption forms, majority is made up of magmatite, and quality is loose, porous.Volcanics wherein contains elements such as abundant mineral calcium, magnesium, iron, zinc, aluminium mainly based on basalt in the world.Basaltic by analysis main component is: silicon-dioxide 45.2%, titanium dioxide 2.31%, aluminium sesquioxide 14.02%, ferric oxide 5.59%, iron protoxide 6.67% etc.Wherein contained iron, aluminium and part titanyl compound can be reduced into the simple substance fine particle under the effect of reductive agent xitix, these elemental metals are because reduction potential difference own can form galvanic cell, degradation of organic substances effectively, form iron ion or aluminum ion, in addition, titanium dioxide itself just has the effect of catalyzed degradation.After the little electrolysis of galvanic cell, add H again
2O
2, make full use of the Fe that is dissolved in the solution
2+, form the Fenton reaction, further decomposing organic matter utilizes ultrasonic wave to quicken organic matter degradation at last.This process is utilized natural heterogeneous catalyst volcanics, makes that the water treatment raw material is cheap and easy to get, the result economical and efficient, can be widely used in treatment of Organic Wastewater.
Summary of the invention
The treatment process that the purpose of this invention is to provide a kind of organic waste water has been utilized the contained special composition of volcanics, and cost is low and treatment effect good.
The technical solution used in the present invention is in turn include the following steps: earlier 10～60 purpose powder are pulverized and be milled into to volcanics; Get this powder 0.5～2g and join in the ascorbic acid solution that 20mL concentration is 30～100mg/L, vibration 15～20min, precipitate and separate, deionized water rinsing, nitrogen protection oven dry down; The powder particle that obtains is joined in the 50mL organic waste water, regulating pH is 1～6 again, vibration 30min; Add 0.1～4mL concentration at last and be 30% H
2O
2, auxiliary with ultra-sonic oscillation 30min～1h, organism is fully degraded get final product.
The invention has the beneficial effects as follows: (1) utilizes oxide compounds such as the activation iron that volcanics itself contained, aluminium, titanium, utilize the reducing property of xitix to become simple substance attached to the volcanics surface its partial reduction, form the little electrolysis of galvanic cell between the particle, simple to operate, consumptive material is few, and material is cheap and easy to get.(2) utilize the equal Fenton reagent of iron ion conduct that generates after little electrolysis, under acidic conditions, constitute the Fenton reaction, reach the purpose of efficient removal organic pollutant with hydrogen peroxide.(2) utilize the accelerated reaction of hyperacoustic " cavitation " effect to carry out, reaction is quickened, degradation of organic substances is saved facility investment and floor space rapidly.
