Abstract

The invention discloses a preparation method of a high-efficiency flocculant. The preparation method is characterized by comprising the following processes: S1, preparing magnetic seeds: selecting magnetite as a main material and quartz sand as a conditioning agent; feeding the main material and the conditioning agent into a ball mill through a feeding system for fine grinding and mixing; feedingthe ball milled material into a magnetic separator for magnetic separation; sieving the material after magnetic separation to obtain a material with the particle size less than 150[mu]m; adding a catalyst, introducing oxygen, and carrying out pre-roasting and high-temperature roasting to obtain the magnetic seeds; and S2, preparing a flocculant: preparing polyacrylamide, citric acid, composite microorganisms, polyferric chloride and bentonite into an aqueous solution; and adding a magnetic seed carrier generated in S1, carrying out mixing, standing and filtering, and drying and roasting the obtained filter residues to obtain the high-efficiency flocculant. The preparation method provided by the invention comprises a magnetic seed preparation process and a flocculant preparation process, the production raw materials are easily available, the production process is simple, and the flocculating effect of the generated flocculant is good.

Description

Technical field [0001] The technical field of electroplating sewage treatment of the present invention specifically relates to a method for preparing a high-efficiency flocculant. Background technique [0002] At present, the sources of electroplating sewage are generally: (1) plating parts washing water; (2) waste electroplating solution; (3) other waste water, including washing the floor of the workshop, washing the plate washing water, condensed water from ventilation equipment, and due to plating tank Leakage or improper operation management caused by "running, running, dripping, leaking" various tank liquids and drainage; (4) equipment cooling water, cooling water in the process of use, except for temperature rise, is not polluted. The water quality and quantity of electroplating wastewater are related to the electroplating production process conditions, production load, operation management and water use methods and other factors. The water quality of electroplating wastew...
