Oil field wastewater special agent 3, the company specifically for oil field 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 the reaction with waste water, it can simultaneously exert the interaction between the adsorbent and bridge, and the oil and colloid in the wastewater are separated and precipitated. Decolorization, COD removal effect. And excellent performance, remove the speed is extremely fast, can completely remove the oil, macromolecules and all kinds of toxic and hazardous substances, in the water alum large, settling speed, decolorization rate of more than 90%, COD removal rate is high, small.
