Abstract
The invention relates to a treatment method of azo dye wastewater, and the treatment method particularly comprises the following steps of: simultaneously adding active carbon fibers and oxidizing agent potassium hydrogen peroxymonosulfate in proportion under the reaction condition of normal temperature and pressure, stirring and treating the azo dye wastewater, wherein the mole ratio of pollutants/potassium hydrogen peroxymonosulfate is 1/10-1/40, and the adding amount of the active carbon fibers is 0.2-1.0 g/L. The treatment method disclosed by the invention is carried out at normal temperature and pressure, is moderate in reaction condition and easy to operate and has a better treatment effect on the azo dye wastewater with various colority.
Description
Technical field
The invention belongs to technical field of sewage, be specifically related to the method that activated carbon fiber catalysis potassium hydrogen peroxymonosulfate is processed azo dye wastewater.
Background technology
Dyestuff is to make fiber and the painted material of other materials, be widely used in the fields such as weaving, printing and dyeing, papermaking, plastics, leather, rubber, coating, printing ink, makeup, sensitive materials, the processing of consequent various waste water from dyestuff is a great problems: waste water from dyestuff has the advantages that organic content is high, colourity is high (can reach 500-500000 doubly), recalcitrant substance is many.Azoic dyestuff account in dyestuff more than 80%, use the most general.Therefore, the processing of azo dyes waste water has very high practical value.
Summary of the invention
The treatment process that the purpose of this invention is to provide a kind of azo dye wastewater, namely a kind of reaction conditions is gentle, and is simple to operate, and the advanced oxidation processes that processing efficiency is high is processed the method for azo dye wastewater.
Method of the present invention is characterized in that, is to add active carbon fibre peacekeeping potassium hydrogen peroxymonosulfate to process Wastewater Dyes class organic pollutant in the waste water that contains the dye class organic pollutant.
When pollutent/potassium hydrogen peroxymonosulfate mol ratio is 1/10～1/40, when the dosage of activated carbon fiber is 0.2g/L～1.0g/L, can guarantee the efficient removal to dyestuff contaminant.
Advantage of the present invention is simple to operate, carries out under normal temperature and pressure, and reaction conditions is gentle; In addition, the present invention also has an outstanding advantages, namely the azo dye wastewater of various colourities is all had good treatment effect.
