Abstract
The present invention provides a kind of environment-friendly treatment method of silk dyeing waste water, the reproducibility decolorising agent iron smelting slag not only rapid reaction of use, percent of decolourization height, but also waste utilization can also further be carried out to iron smelting slag；It is cheap for doing the ion exchange resin of adsorbate, efficiently, adaptation to local conditions, and adsorbate is done with the hot mineral in the days such as bentonite using mixed adsorbent ratio, then there is physical absorption and ion exchanging function, and it is bigger than surface, ion-exchange speed is fast, easily regeneration, have good decolorizing effect to intractable cationic dye wastewater；Extraction process is simple, and energy consumption is low, and extractant need not regenerate, can be cost-effective with Reusability.
Description
Technical field
The present invention relates to technical field of waste water processing, especially, is related to a kind of environment-friendly treatment method of silk dyeing waste water.
Background technology
Since reform and opening-up, China's textile industry increasingly develops, and wherein dyeing development is also extremely rapid, production capacity
Expand, but while yield and the output value increase substantially, the development of dyeing is increasingly be subject to resource and environment system
About, substantial amounts of water is consumed in printing and dyeing production, while produces substantial amounts of waste water again, this color degree of dyeing waste water is high, complicated component, it is impossible to
Directly discharging, intractability is very big, and nowadays most of wastewater treatment mainly uses biochemical method, and treatment technology is single,
And needing addition acid solution or lye to add cost when adjusting the pH value of waste water, a small number of enterprises begin to use various types of
Reverse osmosis membrane handles waste water, high treating effect, but the investment of such film device is big, and operation cost is also very high.
The content of the invention
Present invention aims at a kind of environment-friendly treatment method of silk dyeing waste water is provided, to solve technical problem.
A kind of environment-friendly treatment method of silk dyeing waste water, comprises the following steps：
A, by-pass filtration, aluminium hydroxide and zeolite are added into waste water, is filtered after sewage flocculation, by suspended matter therein
Filter out, remainder contains coloured fine suspension and dissolved matter；
B, reduce, into the waste water after by-pass filtration add reproducibility decolorising agent, handle direct dyeing waste water, be allowed to and its
In direct dyes reduction-decolor reaction occurs so that dye molecule in waste water forms deoxidization, degradation product；
C, adsorb, by the waste water containing deoxidization, degradation product by adsorbate, the deoxidization, degradation in waste water is made due to suction-operated
Product or the absorption of other materials are removed in the surface of solids；
D, ion pair extraction, water-insoluble organic solvent is poured into the waste water after absorption, is together shaken, when two-phase laminated flow,
Just presented in water phase it is colourless, dyestuff build up in upper organic phase；
E, dilute, there are sodium salt and calcium salt in the waste water after extraction, a certain amount of clear water is poured into sewage by its concentration dilution.
Preferably, the reproducibility decolorising agent in step B is iron smelting slag.
Preferably, the adsorbate in step C is using bentonite and the mixture of activated carbon.
The invention has the advantages that：The present invention has the following advantages compared with prior art：
1st, reduce, the reproducibility decolorising agent iron smelting slag not only rapid reaction of use, percent of decolourization is high, but also can be further
Waste utilization is also carried out to iron smelting slag；
2nd, adsorb, it is cheap for doing the ion exchange resin of adsorbate, efficiently, adaptation to local conditions, and used using mixed adsorbent ratio
The hot mineral in the days such as bentonite do adsorbate, then with physical absorption and ion exchanging function, and, ion-exchange speed bigger than surface
It hurry up, easily regeneration, have good decolorizing effect to intractable cationic dye wastewater；
3rd, extract, extraction process is simple, and energy consumption is low, and extractant need not regenerate, can be cost-effective with Reusability.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.
The present invention is further detailed explanation below.
