Abstract
The invention relates to a treatment method of printing and dyeing wastewater. The treatment method comprises the following steps: (1) adding walnut shell flour to obtained printing and dyeing wastewater, wherein the weight of the walnut shell flour accounts for 1.8-2.2 percent by weight of the wastewater; (2) stirring the printing and dyeing wastewater for 45-74 minutes at a stirring speed of 50-120rpm; (3) after stirring is ended, adding silica-gel powder to the printing and dyeing wastewater, wherein the weight of silica-gel accounts for 1.4-1.9 percent by weight of the wastewater; (4) carrying out microwave treatment on the wastewater, wherein the microwave power is 200-250W, and the treatment time is 10-25 minutes; (5) after the microwave treatment is ended, standing for 3 hours; and (6) after standing, taking supernate, wherein the supernate is treated printing and dyeing wastewater. The printing and dyeing wastewater treated by the treatment method has the advantages that the chromaticity is reduced to 21-26 from 573, and the total amount of suspended solids is reduced to 11mg/L-16mg/L from 439mg/L.
Description
Technical field
The present invention relates to a kind for the treatment of process of waste water, particularly relate to a kind for the treatment of process of dyeing waste water.
Background technology
In the manufacturing processed of linsey-woolsey, textile fibres etc., the waste water that has printing and dyeing produces.In dyeing waste water, owing to there being a large amount of dyestuffs, so its colourity is higher, has affected the discharge of dyeing waste water.In addition, in the process of making clothing, chemical fibre generation, can produce a large amount of soft flocks, therefore the suspended substance value in the middle of the waste water of printing and dyeing enterprise is also very high, have even up to the 10g/L left and right, therefore also need to remove suspended substance wherein, reduce its suspension content, reach national dyeing waste water emission standard.In conjunction with above-mentioned, we will find and a kind ofly can reduce colourity in dyeing waste water and the method for suspended substance value simultaneously.
Summary of the invention
The technical problem solved: colourity and the higher problem of suspended substance value in dyeing waste water.
Technical scheme: the invention discloses a kind for the treatment of process of dyeing waste water, treatment step is as follows: (1) will add walnut shell flour in the dyeing waste water of getting, 1.8wt%～2.2wt% that the weight of walnut shell flour is waste water weight; (2) dyeing waste water is stirred, churning time is 45～74min, and mixing speed is 50～120rpm; (3) stir and finish to add silica-gel powder, 1.4wt%～1.9wt% that silica gel weight is waste water weight in backward dyeing waste water; (4) waste water is carried out to microwave treatment, microwave power is 200～250w, and the treatment time is 10～25min; (5) microwave treatment is standing after finishing, and time of repose is 3h; (6) get supernatant liquor after standing, dyeing waste water after supernatant liquor is and processes.Wherein, the weight of walnut shell flour is preferably the 2.2wt% of waste water weight.The order number of walnut shell flour is preferably 100～200 orders.Silica gel weight is preferably the 1.4wt% of waste water weight.The order number of silica gel is preferably 150～250 orders.
Beneficial effect: the dyeing waste water of crossing by disposal methods of the present invention, the colourity of dyeing waste water is down to 21～26 from 573, and total suspended solids is down to 11mg/L～16mg/L from 439mg/L.After processing, in the waste water of printing and dyeing enterprise, colourity and suspended substance value have obtained declining to a great extent.
