Abstract
The invention discloses a method for preparing a coagulating and decolorizing agent for printing and dyeing wastewater treatment. The method comprises the following steps: (1) sequentially adding 12-14 parts by mass of dicyandiamide, 25-30 parts by mass of aluminium chloride, 7-8 parts by mass of ammonium chloride and 25-30 parts by mass of formaldehyde into a reaction kettle by adopting a one-step process, uniformly stirring and mixing; (2) heating the solution to 45-50 DEG C at the speed of 1 DEG C/min and reacting for 2-3 hours; (3) heating the solution to 65-70 DEG C at the speed of 5 DEG C/min and reacting for 1-2 hours; (4) heating the solution to 93-95 DEG C at the speed of 2 DEG C/min and reacting for 2-4 hours; and (5) cooling to room temperature and barreling. The coagulating and decolorizing agent for the printing and dyeing wastewater treatment, prepared by adopting the method disclosed by the invention, is good in precipitation effect, obvious in decolorization effect and simple in manufacturing process.
