Embodiment 1
[0019] Such as figure 1 As shown, the evaluation process of clear water preparation and oxygen exposure treatment of diluted polymer solution in polymer-containing sewage was implemented in the Nansi Combined Station of the Second Oil Production Plant of Daqing Oilfield Co., Ltd., with a treatment capacity of 1.0m 3 / h, the concentration of the polymer mother liquor is 5000mg / L, and the polymer mother liquor is diluted to 1000mg / L by exposure to oxygen-containing sewage.
[0020] 1. Air compressor oxygen exposure + diluted polymer
[0021] The air is compressed by the air compressor and enters the air storage tank to stabilize the pressure. The stabilized air is directly mixed with the poly-containing sewage in the air-water static mixer. After being released by the dissolved air release tank for 4 hours, it enters the external water tank for external transport. The polymer-containing sewage in the water tank is fully mixed with the polymer mother liquor in the polymer mother...
