Abstract
The invention discloses a product for printing and dyeing sewage, which belongs to the water treatment field. The product comprises a flocculating agent and bentonite, wherein the proportions are 20-50 parts of flocculating agent, 20-60 parts of bentonite and the balance of sulfate. The flocculating agent is a polymeric flocculant and/or a cation flocculating agent, the polymeric flocculant is polyaluminum chloride. The waste water processed by the product is approximately transparent, and can reach the national standard or enables regenerative utilization. The processed sediment can be reused without secondary chemical pollution.
Description
Technical field
The present invention relates to a kind of dyeing and printing sewage treating product, belong to water treatment field.
Background technology
China's textile printing and dyeing industry is larger, and quantity discharged accounts for more than 70% of trade effluent, and dyeing and printing sewage complicated component, concentration are high, colourity is dark, hard to manage.The method of processing dyeing waste is commonly used at present has biological oxidation process etc., and wherein the biological oxidation process effect is better, but complex treatment process, and the cycle is long.
Summary of the invention
The present invention provide a kind of operate simple and easy, cost is lower, technology is simple, the treating product of good purification.
The present invention realizes through following technical scheme:
A kind of dyeing and printing sewage treating product, this product comprises flocculation agent, wilkinite, flocculation agent 20-50 part wherein, wilkinite is 20-60 part, surplus is a vitriol.
Said dyeing and printing sewage treating product, said flocculation agent are polymeric flocculant and/or cationic flocculant.
Said dyeing and printing sewage treating product, said polymeric flocculant are Poly aluminum Chloride (PAC).
Beneficial effect of the present invention is:
Utilize the approximate water white transparency of waste water after treating product of the present invention is handled, being up to state standards perhaps can be reproduced utilization, and the throw out after the present invention handles can be utilized once more, and does not have the secondary chemical pollution.
Embodiment
Below in conjunction with embodiment technical scheme of the present invention is further set forth.
A kind of dyeing and printing sewage treating product, this product comprises flocculation agent, wilkinite; Flocculation agent 20-50 part wherein, wilkinite is 20-60 part, surplus is a vitriol; Said flocculation agent is polymeric flocculant and/or cationic flocculant, and said polymeric flocculant is a Poly aluminum Chloride (PAC).
The wilkinite specific surface area is bigger, it is carried out acidification after, it is big that specific surface area, channel diameter become, adsorptive power strengthens.
Poly aluminum Chloride (PAC) is a kind of cation polymeric flocculant, adds constantly hydrolysis in the dyeing waste water, in hydrolytic process, condenses, adsorbs, precipitates a series of materializing procedures, and the wilkinite small molecules is evenly distributed on the flocculence thing, accelerates the adsorption treatment of solution.
Claims (3)
1. dyeing and printing sewage treating product, it is characterized in that: this product comprises flocculation agent, wilkinite, flocculation agent 20-50 part wherein, wilkinite is 20-60 part, surplus is a vitriol.
2. dyeing and printing sewage treating product according to claim 1, it is characterized in that: said flocculation agent is polymeric flocculant and/or cationic flocculant.
3. like the said dyeing and printing sewage treating product of claim 2, it is characterized in that: said polymeric flocculant is a Poly aluminum Chloride (PAC).
