Embodiment 1
[0022] Embodiment 1, preparation clear water agent compound synergistic system
[0023] 1ml of hydroxamic acid modified polyacrylamide (purchased from SNF Company in France, trade name KM800, made into an aqueous solution with a mass fraction of 1%) and 2.2ml of acrylamide-dimethyldiallylammonium chloride copolymer (CAS number is 26590-05-6, molecular weight is 10 4-5 ) mixed to obtain a water agent compound synergistic system.
[0024] In the compound type clear water agent prepared in this example, the quality of the cationic type clear water agent (acrylamide-dimethyl diallyl ammonium chloride copolymer) and the anionic type clear water agent (hydroxamic acid modified polyacrylamide) The ratio is 2.2:1.
Embodiment 2
[0025] Embodiment 2, preparation clear water agent compound synergistic system
[0026] 1.2ml of hydroxamic acid-modified polyacrylamide (purchased from SNF Company in France, trade name KM800, prepared as an aqueous solution with a mass fraction of 1%) and 2ml of acrylamide-dimethyldiallylammonium chloride copolymer (CAS number is 26590-05-6, molecular weight is 10 4-5 ) and mixed to obtain a compound type clear water medicament.
[0027] In the compound type clear water agent prepared in this example, the quality of the cationic type clear water agent (acrylamide-dimethyl diallyl ammonium chloride copolymer) and the anionic type clear water agent (hydroxamic acid modified polyacrylamide) The ratio is 2:1.2.
Embodiment 3
[0028] Embodiment 3, preparation clear water agent compound synergistic system
[0029] 1.6ml of sodium butyl xanthate (purchased from Yantai Junbang) and 1.6ml of dimethylamine-epichlorohydrin-ethylenediamine copolymer (molecular weight 10 4 ) and mixed to obtain a compound type clear water medicament.
[0030] In the compound type clear water agent prepared by the present embodiment, the mass ratio of the cation type clear water agent (the copolymer of dimethylamine-epichlorohydrin-ethylenediamine) and the anionic type clear water agent (organic amine phosphate) is 1: 1.
[0031] The composite clear water medicament prepared in Example 1-3 was used to treat the sewage containing polymer, and the bottle test method was used to evaluate the performance of the composite clear water medicament of the present invention:
[0032] The specific steps are:
[0033] 1. The polymer-containing sewage water sample is provided by an oilfield in the Bohai Sea. The polymer-containing sew...
