A decolorant PAD for waste polymer sulfonate mud treatment was synthesized using acryl amide (AM) and methyl methacryloxyethyl trimethyl ammonium chloride (DMC). The PAD was evaluated on its decoloring performance. The decoloring mechanism of PAD was studied using IR scan and source color analysis of polymer sulfonate mud. It was proved that optimum decoloring performance was achieved at 0.35 g/L PAD, pH of waste fluid of 4, agitation speed of 30 r/min, and agitation time of 2 min. Under these conditions, the colourity of water effluent was controlled to less than on tenth of that of the original fluid, and COD was reduced to 93.8%. Comparison of PAD with other decolorants showed that PAD had higher decoloring rate, less residue floes which is less than 1/2 of other decolorants, and high COD removal capacity. PAD is an ideal, highly efficient decolorant for waste polymer sulfonate mud treatment. ©, 2014, North China Petroleum Administration Drilling Technology Research Institute. All right reserved.
