Abstract
The invention relates to a method for treating printing and dyeing wastewater through catalytic oxidation. The method comprises the following steps: adding Co3(PO4)2 and an oxidant into the printing and dyeing wastewater respectively, mixing, and then performing the static settlement or sedimentation to obtain the treated printing and dyeing wastewater. The Co3(PO4)2 is an effective and quick oxidation catalyst, can quickly catalyze peroxide to generate a free radical with a strong oxidizing property, and is enabled to be in oxidation-reduction reaction with dye to achieve the purpose of high reaction speed and high decolourization ratio. The treatment of the printing and dyeing wastewater can be carried out under the natural condition, without illumination.
Description
Technical field
The invention belongs to the method for wastewater treatment field, particularly a kind of method of catalytic oxidation treatment dyeing waste water.
Background technology
Along with the development of dyestuffs industries, its problem of environmental pollution brought also becomes increasingly conspicuous, and dyeing waste water is one of main source of environmental pollution, and its quantity discharged is large, colourity is high, degradability is poor.
Another characteristics of dyeing waste water are that colourity is high, and what have can be up to more than 4000 times.So one of vital task that waste water containing dye is processed is exactly the processing of decolouring, and needs to study and select the treatment process that is conducive to decolour for this reason.Wherein, the oxidative decoloration method is by means of redox reaction, to destroy conjugated structure or the chromophoric group of dyestuff, the organism in waste water can be become to carbonic acid gas, water and oxynitride etc. simultaneously.In the decolouring of dyestuff was processed, the superoxide such as hydrogen peroxide were the oxygenants often used, but while using separately oxidation capacity a little less than, oxidation rate is slow, and the mineralising poor effect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of catalytic oxidation treatment dyeing waste water, the method be a kind of effectively, oxide catalyst fast, but the quick catalysis superoxide produces the strong oxidizing property free radical, make it and dyestuff generation redox reaction, speed of reaction is fast, and percent of decolourization is high; This invention, without illumination, can be carried out under natural condition.
The method of a kind of catalytic oxidation treatment dyeing waste water of the present invention comprises: in dyeing waste water, add respectively cobaltous phosphate Co

2And oxygenant, stir the processing of decolouring, then staticly settle or sedimentation, obtain the dyeing waste water after processing, wherein the volume ratio of dyeing waste water and oxygenant is 4～6:1, the proportioning of cobaltous phosphate and dyeing waste water is 2.0～25g:1L.
Described oxygenant is one or more in hydrogen peroxide, hydrogen persulfate aqueous solutions of potassium, peroxide acetate aqueous solution.
The mass percent concentration of described oxygenant is 0.5～10%.
Described churning time is 30～60min.
Described precipitation or settling time are 30～60min.
In wastewater treatment without considering cobaltous phosphate Co
