Oil (ink) waste water for pharmaceutical 3, the company specifically for oil (ink) wastewater treatment independent research and development of high-tech products. On the basis of the original pharmacy, the synthetic high molecular weight graft copolymer and the unique chemical structure are synthesized. After the reaction with the wastewater, the adsorption and bridging of the particles can simultaneously play the role of the macromolecule Organic matter, colloidal coagulation and separation of precipitation; excellent decolorization, COD removal effect. And excellent performance, removal speed is extremely fast, can completely remove the oil and glial, alum in the water large, settling speed, decolorization rate of more than 90%, COD removal rate is very high, small sludge.
