| description | The invention relates to the technical field of polyacrylamide synthesis, and discloses a novel polyacrylamide synthesis process which comprises the following steps: S1, removing impurities; s2, mixing and blending; s3, blending: adjusting the pH value to 6.2-6.8 by using a sodium hydroxide solution; s4, carrying out polymerization; s5, primary adjustment: adding dimethylamine and formaldehyde, reacting for a certain time at a certain temperature, and then adding dimethyl sulfate; s6, secondary regulation: adding thiosemicarbazide into the polyacrylamide primary regulation product; according to the invention, primary adjustment and secondary adjustment are added in the traditional polyacrylamide synthesis process; a flocculating constituent is denser through one-time adjustment, the flocculation process is promoted, and the sewage treatment efficiency is improved; according to the secondary regulation, quantitative thiosemicarbazide is added into polyacrylamide, so that the polyacrylamide can form nitrogen an |
