Embodiment 1
[0015] Weigh 800 g of cationic polyacrylamide and 200 g of polyaluminum chloride, mix the two agents into a blender at normal temperature and pressure, and stir for 40 minutes to prepare the product.
Embodiment 2
[0017] Weigh 900 g of cationic polyacrylamide and 100 g of polyaluminum chloride, mix the two agents into a blender under normal temperature and pressure, and stir for 40 minutes to prepare the product.
Embodiment 3
[0019] Weigh 850 g of cationic polyacrylamide and 150 g of polyaluminum chloride, mix the two agents into a blender under normal temperature and pressure, and stir for 40 minutes to prepare the product.
[0020] The organic macromolecule coagulant aid of the present invention is applied to the Daqing No. 5 Oil Production Plant Xingwuyi Combined Station. The sewage treatment capacity of this station is 16000m3 / d. Before the test, 640 kilograms of common coagulant aid cationic polyacrylamide was added every day. The dosing concentration is 40ppm; after adding the organic polymer coagulant aid of the present invention, add 20 kilograms every day, and the dosing concentration is 1.25ppm. The oil content and suspended solids in the filtered sewage water before dosing were 18.7mg / l and 9.1mg / l respectively, basically up to the standard. The oily and suspended solids in the filtered sewage water after dosing were 14.6mg / l and 6.5mg / l respectively. The effect is obviously better tha...
