Embodiment Construction

[0015] In order to better illustrate the present invention, give examples as follows:

[0016] Synthesis of lipophilic monomer: Add 2g of concentrated sulfuric acid to 100ml of glacial acetic acid at 20°C to make a solution, add 5g of acrylonitrile dropwise to the solution while stirring, and then add 20g of diisobutylene dropwise into the solution to maintain the reaction system The temperature was at 45° C., and after stirring and reacting for 3 hours, 5 times the volume of secondary water was added thereto, stirred evenly and then left to stand. Needle-like crystals were precipitated, filtered, washed with water, and freeze-dried.

[0017] Synthesis of polyacrylamide water purifying agent: add deionized water 50g, AM (acrylamide) 5g, cationic monomer DAC (acryloyloxyethyltrimethylammonium chloride) 9g, lipophilic monomer (N -(1,1,3,3-Tetramethylbutyl)-2-acrylamide) 0.5g, dodecyltrimethylammonium chloride 1.5g, stirred and emulsified on a magnetic stirrer, constant temperat...

Abstract

The invention discloses a synthetic method for a multifunctional polyacrylamide purifying agent, which comprises synthesis of oleophilic monomers, synthesis of the polyacrylamide purifying agent and composition of a compound evocating agent which is composed of ammonium ferrous sulfate, ammonium persulphate, an azo evocating agent, an auxiliary evocating agent, ammonia and sodium formiate. The value and significance of the synthetic method lie in that the synthetic method can be more widely applied in different sewage treatment technical fields of industrial sewage (including sewage caused byprinting, paper making, galvanoplastics, machinery work, food industry, wine making industry and leather, etc.), domestic sewage (including living sewage of people, sewage of catering and tourism industries, etc.) and sewage from oil fields, etc.

Description

technical field [0001] The invention relates to a synthesis method of chemicals, in particular to a synthesis method of chemicals used for waste water and sewage treatment, that is, a synthesis method of a multifunctional polyacrylamide water purifier. Background technique [0002] With the rapid development of industrial and agricultural production and the continuous improvement of people's living standards, the demand for water is also increasing. At the same time, the pollution of water resources is also becoming more and more serious. According to the survey, industrial water generally accounts for 70-80% of urban water, and the amount of various industrial and domestic sewage that needs to be treated is increasing rapidly. In addition, most of my country's major oilfields have entered the middle and late stage of oilfield development. At present, the average comprehensive water content of oilfield output fluid has exceeded 80%, resulting in a large amount of oily sewage...
