Description

technical field

[0001] The invention relates to a cyclic amidine-based polymer flocculant and a preparation method thereof. The flocculant has the characteristics of high intrinsic viscosity, high charge density, and good water solubility, and is suitable for oily wastewater treatment in oil fields, and belongs to the flocculation in the field of water treatment technology Dosage preparation technology. Background technique

[0002] With the development of petrochemical industry, the discharge of oily wastewater is increasing day by day. Among them, a large amount of wastewater is generated in oilfield tertiary oil recovery. For example, treating oilfield wastewater and recycling it for reinjection water is an effective measure to achieve sustainable development of water resources, and it is also an important issue facing oilfields. topic. This reinjection water must meet certain technological requirements, otherwise it will not only cause sedimentation and blockage of pipe...
