Description

A method of degradation crystal violet waste water
Technical field
The invention belongs to field of environment protection, in particular to a kind of method for crystal violet waste water of degrading.
Background technique
Crystal violet, molecular formula C23H31ClN2O3, molecular weight 479.029.It is a kind of with bright-coloured pink artificial conjunction At basic dye, be widely used for paper industry and dyeing, such as typing paper, glazed paper, feather products, straw and leather Deng dyeing.Crystal violet has strong fluorescence in the solution, and stability is good, and chroma in waste water is high, and biodegradability is poor, on land and Biological accumulation in aquatic ecosystem all has an impact to environment and human health.Therefore, crystal violet waste water is handled As the task of top priority.
The degradation crystal violet method studied at present has absorption method, chemical oxidization method, Fenton method, electrochemical oxidation process and light Catalysis method etc..Crystal violet is adsorbed using adsorbent, it is desirable that complicated pre-treatment and percent of decolourization is relatively low；Chemical oxidization method is adopted With oxidizing crystal violet, it be easy to cause secondary pollution；Electrochemical oxidation process rapidly and simply, but since energy consumption is high, power consumption Amount is big and is difficult to be widely applied.Fenton method and photocatalytic method are using the hydroxyl radical free radical oxidation crystal violet generated, wherein with light Catalytic degradation crystal violet most study, this method degradation is more thorough, but rate is very low, and degradation time is longer, degradation process Complexity, reaction condition are difficult to control, and expend biggish energy, it is difficult to meet industrial enterprise's production requirement, and the COD in solution is de- Except efficiency is poor, it is difficult the large-scale application in actual waste water processing.
Amino benzenes derivates be it is a kind of can electrochemically initiated polymerization monomer, they are easy life on the electrode At aniline free radical, aniline free radical attack dye molecule crystal violet generates the bigger organic molecule of molecular weight, with molecular weight Increase, the ability for being dissolved in water substantially reduces, and then is precipitated out from water, and extra amino benzenes derivates can also be voluntarily Mutually polymerization generates polyaniline, precipitates from water, therefore can remove water pollutant with fast purification water quality.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of methods of crystal violet waste water of degrading.
The purpose of the present invention is achieved through the following technical solutions: a method of degradation crystal violet waste water, the party Method the following steps are included:
(1) by crystal violet waste water grid desilting；
(2) by step (1) treated crystal violet waste water is heated to 10-60 DEG C, adjust pH to 2-7, filtered after 1 hour, Obtain filtrate；
(3) using step (2) treated filtrate as electrolyte, using platinum, iron, copper, gold, ruthenium, palladium, graphite, lead, BDD electricity One of pole uses saturated calomel electrode for reference electrode as oxidation working electrode, and graphite electrode is to aoxidize to electrode It under conditions of voltage is 1.0-1.5V, aoxidizes two minutes, radical scavenger is added, be electrolysed the fracture small molecule of generation at this time certainly Flocculent deposit is generated in conjunction with radical scavenger by base；By the electrolyte membrane filtration after oxidation, clear liquid is obtained.
Further, in the step 3, radical scavenger is selected from aniline, benzene methanamine and phenyl ethylamine, radical scavenger Additional amount be 0.2-2 ml ls of waste water.
The beneficial effects of the present invention are: the present invention generates molecular fragment a part precipitating using electrolysis method degradation crystal violet Out, the substances such as a part and the aniline added in electrolyte, which react, generates class polyaniline compound and is precipitated out, very The COD value of waste water is reduced in the short time.Compared with photocatalysis or high pressure method for electrically, present invention substantially reduces degradation times And electrolysis energy consumption.It is suitble to Quick Pretreatment early period of large-scale industry waste water.
