Preparation and application of amphoteric poly(methacryloxyethyltrimethylammonium chloride acrylamide acrylic acid) terpolymer (A PAM)

[Preparation method] Preparation of amphoteric poly(methacryloxyethyltrimethylammonium chloride acrylamide acrylic acid) terpolymer (A PAM)

First add the metered amount of methacryloyloxyethyl trimethylammonium chloride (DMC), acrylamide (AM) and acrylic acid (AA) into the reactor according to a certain ratio, and then add an appropriate amount of water and additives.

[application]

(1) Biochemical sludge test of sulfonation plant

Table 11-19 lists the flocculation and dewatering test results of amphoteric polyacrylamide flocculant on the biochemical sludge of P&G's sulfonation plant.

Table 11-19 Flocculation and dewatering test results of biochemical sludge from sulfonation plant

(2) Flocculation and dewatering test of biochemical sludge

Table 11-20 is the flocculation and dewatering test results of the biochemical sludge of Guangzhou Datansha Wastewater Treatment Plant with A PAM series of flocculants

Table 11-20 Flocculation and dewatering test results for industrial wastewater, domestic sewage and biochemical sludge

(3) Dewatering performance test of sludge

Because the fine particles in the sludge are negatively charged and repel each other, and some of the sludge combines with the surface attached water to form a gel, they can be stably distributed in the water, and the sedimentation performance is poor.

According to the manufacturer’s quotation, the polymer grade AMPS produced in Xinxiang is 18,000 yuan/ton, 60% DMDAAC is 16,000 yuan/ton, 1 the 99.
