Embodiment 1
[0016] Preparation of water purifying agent: Add 54kg of ionized water, 20kg of polyaluminum ferric silicate, 15kg of polyaluminum trichloride and 1.0kg of sodium carboxymethyl starch in sequence, and then add 10kg of polydimethylsilica after complete dissolution Allyl ammonium chloride is stirred evenly at a speed of 100-150 rpm to obtain the water purifying agent YTJS-01 for the treatment process of the pipeline mixer of the pipeline containing poly in offshore oilfields.
[0017] Performance evaluation:
[0018] Experimental groups 1 and 2 evaluated the performance of water purifiers for two kinds of polymer-containing sewage respectively, and each group of experiments conducted three parallel experiments, and the parallel experiment numbers were A, B, and C. The experimental results are listed in Table 1.
