Description

A kind of dyeing and printing sewage treatment agent

Technical field

The present invention relates to a kind of sewage treatment drug, specifically a kind of dyeing and printing sewage treatment agent.

Background technology

Classify according to sewage source, sewage is divided into sanitary sewage and production waste.Production waste includes trade effluent, agricultural Sewage and medical sewage.Trade effluent is the topmost part in production waste, with industrialized development, discharge Trade effluent is more and more, and life of the trade effluent to environment and the mankind brings very big influence, if sewage is processed not in time, The quality of air quality and water resource is not only directly affected, the physical and mental health of people can be also influenceed.

Dyeing industry is the important component of textile industry, and dyeing industry water consumption is big, and a large amount of dyeing and printing sewages are all produced daily. The processing method of current existing dyeing and printing sewage mainly has bioanalysis, electrolysis, chemical method and photocatalytic method.Bioanalysis takes up an area face Product is big, and use condition is harsh, and using effect is not satisfactory；Although electrolysis using effect is good, energy resource consumption is big, is processed into This height, narrow application range；Photocatalytic method can cause that organic matter is converted completely, will not produce secondary pollution, but photocatalytic method Effect for reducing COD and BOD does not reach the requirement of people.Chemical method is to carry out the most widely used method of sewage disposal, I.e. to delivering chemical agent in dyeing and printing sewage.But existing chemicals treatment high cost, has secondary pollution, this is just people's Using bringing inconvenience.

The content of the invention

It is an object of the invention to provide a kind of dyeing and printing sewage treatment agent, with asking for solving to propose in above-mentioned background technology Topic.

To achieve the above object, the present invention provides following technical scheme：

As further scheme of the invention：Nanometer concavo-convex rod soil is using methyl nanometer concavo-convex rod soil, ethyl nanometer convex-concave One or several mixture of rod soil and methylol nanometer concavo-convex rod soil, modified starch is formed sediment using cornstarch, potato One or several mixture of powder, Rhizoma Nelumbinis starch and rice starch, highly basic uses NaOH, potassium hydroxide and calcium hydroxide One or several mixture.

As further scheme of the invention：Flocculation aid includes polyacrylamide, activated silicic acid and sodium alginate, polypropylene The mass ratio of acid amides, activated silicic acid and sodium alginate is 4-6:2-3:1.

The preparation method of the dyeing and printing sewage treatment agent, comprises the following steps that：

Step one, sunflower straw is crushed and is fragmentated, and the deionized water of 3-5 times of weight is added in fragment and is stirred Uniformly, then by solution boiled under 100-150 degrees Celsius 50-120 minutes, then carry out separation of solid and liquid, collect sunflower straw filtering Liquid, gives over to standby；

Step 2, micarex, diatom ooze and bentonite are calcined 20-45 minutes and crushed under 820-950 degrees Celsius Mica stone powder, diatom ooze powder and bentonite powder into 20-30 mesh, then by mica stone powder, diatom ooze powder and swelling Native powder is individually positioned in 25-40 minutes in the hydrochloric acid of the hydrochloric acid of 0.5mol/L, 0.5mol/L sodium hydroxide solutions and 1mol/L, It is washed with deionized water again to neutrality and is dried to obtain modified micaceous stone powder, modified diatom ooze powder and modified alta-mud powder End；

Step 3, flocculation aid and modified starch are added stirring reaction 3-5 hours, mistake in the deionized water of 2-5 times of weight Reacted product is filtered, product is clean using distilled water flushing and dries, standby；

Step 4, by ferrous sulfate, product, activated carbon, shitosan, alum, ferric trichloride, highly basic, modified micaceous stone flour End, modified diatom ooze powder and modified alta-mud powder are added in deionized water, are entered in nitrogen protection atmosphere and 38-55 degrees Celsius The stirring reaction of row 2-5 hours, is then warmed up to 70-90 degrees Celsius and adds nanometer concavo-convex rod soil and sunflower straw to filter Liquid is stirred 1-3 hours, obtains mixture；

Step 5, dries, you can obtain finished product under mixture is placed on into 95-120 degrees Celsius.

Compared with prior art, the beneficial effects of the invention are as follows：Raw material sources of the present invention extensively, fit by preparation process is simple For large-scale industrial production；Each component compounding of the invention, plays coordinative role, can not only continue treatment colourity The dyeing and printing sewage higher with concentration, while so that the pollution sewage after treatment reaches effect that is colourless, tasteless and reducing COD value Really, the water quality after treatment can be recycled, and reach discharging standards, not have secondary pollution, wide market.
