Embodiment 1

[0015] A high-efficiency organic coagulant, the specific preparation steps are as follows:

[0016] (1) Adding methylolated polyacrylamide and an ethanol solution with a mass concentration of 63% into the container, stirring and mixing;

[0017] (2) Raise the temperature of the container to 70-85° C., adjust the pH of the solution after 3 hours, and react under acidic conditions for 6 hours;

[0018] (4) Add quaternary ammonium salt monomer into the container, stir and mix evenly, then drop polymethyldiallyl ammonium chloride (HCA) into the reaction kettle, react for 9 hours, and obtain the organic coagulant.

[0019] The adding speed of the polymethyldiallylammonium chloride (HCA) is not more than 0.2ml / min.

Abstract

The invention relates to the technical field of coagulants, and in particular, relates to a high-efficiency organic coagulant which is specifically prepared by the following preparation steps: (1) adding hydroxymethylated polyacrylamide and an ethanol solution with the mass concentration of 63% into a container, and stirring and mixing; (2) raising the temperature of the container to 70-85 DEG C,adjusting the pH value of the solution after 3 hours, and reacting for 6 hours under an acidic condition; and (4) adding a quaternary ammonium salt monomer into the container, uniformly stirring and mixing, dropwise adding polymethyldiallylammonium chloride (HCA) into a reaction kettle, and reacting for 9 hours to obtain the organic coagulant. The organic coagulant has the beneficial effects thatthe polymerization reaction is promoted to be more sufficient through the polymethyldiallyl ammonium chloride (HCA), the preparation method is simple, secondary pollution such as heavy metal is not generated, the prepared organic coagulant is good in coagulation effect, the putting amount of treated wastewater can be reduced, and the sludge dewatering treatment cost and the later treatment cost can also be reduced.

Description

technical field [0001] The invention relates to the technical field of coagulants, in particular to an efficient organic coagulant. Background technique [0002] Organic coagulants are widely used in the primary coagulation treatment of papermaking, textile, printing and dyeing wastewater and organic wastewater clarification. effect. [0003] Existing organic coagulants are used in wastewater treatment with excessive dosage, high medicament cost and high labor cost. Contents of the invention [0004] In order to solve the problems of the prior art, the invention provides a high-efficiency organic coagulant that can reduce the dosage and save costs. [0005] The technical scheme of the present invention is as follows: [0006] A high-efficiency organic coagulant, the specific preparation steps are as follows: [0007] (1) Adding methylolated polyacrylamide and an ethanol solution with a mass concentration of 63% into the container, stirring and mixing; [0008] (2) Rai...
