Abstract
The invention relates to a treatment method of seawater applied in active dye dyeing, and the treatment method comprises the following steps: firstly adding polyaluminum chloride to seawater for flocculation and settlement, standing and settling for 1-2 hours, then adding sodium hydroxide and sodium carbonate for softening, carrying out ion exchange with 732 cation exchange resin, and finally adjusting the pH value of the seawater to be neutral with diluted sulfuric acid, thus obtaining the seawater applied in active dye dyeing. By using the treatment method, cations in the seawater are selectively removed, the treatment cost is low, the operation is easy, and the treated seawater can reach the process technology requirement of the active dye dyeing, so that the active dye dyeing can be carried out by using the freshwater active dye dyeing technical process and method, the consumption of freshwater in the active dye dyeing process is greatly reduced, and the treatment method has good application prospects.
Description
Technical field
The invention belongs to the brine disposal field, particularly a kind of method of seawater treatment that is applied to reactive dyeing.
Background technology
Dyeing is annual to consume a large amount of Freshwater resources, and conserve water resource how has become the restriction dyeing and had social concern with development.In the face of increasingly serious water resources lacks, people begin to attempt new water source, as the exploitation and the comprehensive utilization of seawater resources, meet the trend of dyeing Sustainable development.Seawater is directly applied to the reactive dyeing economic method of a kind of water saving of can yet be regarded as through pre-treatment.As far back as the eighties in last century, existing research promptly is used for textile industry with seawater without any processing.
Contain more inorganic salts, particularly Na in the seawater
+Ionic content is very high, needs to add that a large amount of neutral electrolytes is short dyes in the process of cellulosic fibre and dye on the reactive dyestuffs, so can keep Na wherein in the pre-treatment process of seawater
+, K
+Ion.Contain a large amount of Ca in the seawater
2+, Mg
2+Ion, hardness is higher, so must remove Ca before seawater is used
2+, Mg
2+Ion for other the trace metal ion in the seawater, can be removed by methods such as ion-exchange or sequestrant complexings.Therefore, can be applied to the dyeing of reactive dyestuffs by optionally removing some ion in the seawater.

Through above-mentioned treating processes, Na in the seawater
+Ion content increases to about 10.0g/L, Ca
2+, Mg
2+Ion content declines to a great extent, Cu
2+, Ag
+, Hg
2+Plasma content drops to below the 1ppm.To handle seawater at last and be applied to reactive dyeing, and with same processing condition under the contrast of fresh water dyeing sample.Before the dyeing of fresh water dyeing sample, need the Na about the 10.0g/L of replenishing more
+Ion.
Beneficial effect
The present invention optionally removes the positively charged ion in the seawater, processing cost is cheap, easy handling, make seawater can reach the Technology requirement of reactive dyeing, make its technical matters that can adopt the fresh water reactive dyeing and method, significantly reduced the fresh water dosage of reactive dyeing process, had a good application prospect.
