Description
Technical field
The invention belongs to technical field of disperse dyes, and in particular to the processing of sulfur acid waste water in a kind of disperse dyes production
Method.
Background technology
Waste water from dyestuff is one of generally acknowledged reluctant pollutant, and the waste water from dyestuff being discharged into environment is mainly derived from
The fields such as weaving, printing, printing and dyeing, dyestuff manufacture, food processing.The nearly 800000t of world's annual production of dyestuff at present, wherein about
50% is azo dyes, and its chemical composition contains aromatic rings, has difficult for biological degradation, high toxicity and potential carcinogenicity.Therefore
, will to reach the discharge of national environmental protection regulation there is an urgent need to develop to meet actual waste water processing feature and cost-benefit technology
Ask.
Waste water in disperse dyes production, most of is all high COD acid waste water, in terms of wastewater treatment substantially all
It is to be neutralized with lime, then obtains low COD waste water and calcium sulfate waste residues, low COD waste water is directly entered waste water pipe network, and calcium sulfate gives up
Slag is drawn by lorry and goes to fixed-end forces center.
The content of the invention
The processing method of sulfur acid waste water, provided by the invention in being produced it is an object of the invention to provide a kind of disperse dyes
Method has convenient for production, has pollution-free, efficient advantage.
The processing method of sulfur acid waste water, its step are as follows in a kind of disperse dyes production：
Step 1, waste water is subjected to filtration treatment, obtains no particle sulfur acid waste water；
Step 2, sulfur acid waste water is added in cell reaction kettle, carries out mixed aeration reaction, sealing degraded；
Step 3, absolute ethyl alcohol will be added after waste water packing after degraded, is filtered after layering, obtain ethanol water mixed liquid；
Step 4, membrane filtration after ethanol water mixed liquid is evaporated under reduced pressure, you can obtaining can waste discharge.
Filter type in the step 1 uses metal filter screen or foaming body pore structure.
Mixed aeration gas uses ozone and Peracetic Acid Gas in the step 2.
The proportioning 1 of the ozone and Peracetic Acid Gas:1.2-1.9.
Decomposition voltage in the step 2 is 15-25V, spacing 2-4cm.
Electrolysis area in the step 2 is 100-400cm2。
Filtering uses solid-liquid filtration in the step 3.
