Printing and dyeing wastewater special agent 2, the company specifically for printing and dyeing wastewater treatment independent research and development of high-tech products. Which is a kind of inorganic polymer graft copolymer with high molecular weight and unique chemical structure. After dissolving in water, it can simultaneously exert the interaction between the adsorbent and the neutralization of the particles, and the suspended matter and colloid in the waste water are separated and precipitated. Decolorization, COD removal effect. And excellent performance, remove the speed is extremely fast, can completely remove all kinds of glial, alum in the water large, settling speed, decolorization rate of more than 90%, COD removal rate is very high, small sludge.
