Abstract
The invention discloses a composite microbial bacterial agent for electroplating wastewater treatment and a preparation and use method thereof. The method steps are as follows: (1), Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens subspecies, and Bacillus amyloliquefaciens Bacillus, Bacillus, Yeast, Bacillus cereus, Klebsiella, and Acinetobacter baumannii are uniformly mixed according to the volume ratio to form a composite bacterial agent; (2) The electroplating wastewater after physical and chemical treatment is continuously passed into the biochemical pool In the process, the bacteria agent described in (1) is added into the biochemical pool according to 0.05%-0.5% of the effective volume of the biochemical pool to carry out the biochemical reaction. The composite microbial agent can effectively reduce COD and ammonia nitrogen in the electroplating wastewater, solve the problem that the biochemical pool of the electroplating wastewater is easy to collapse, and improve the treatment efficiency. At the same time, the invention also has the advantages of low cost, no pollution, no toxicity, high efficiency, Easy to implement and other advantages.
Description
technical field [0001] The invention belongs to the technical field of electroplating wastewater treatment, and in particular relates to a composite microbial bacterial agent for electroplating wastewater treatment and a preparation and use method. Background technique [0002] Electroplating is a process in which the plated parts undergo chemical or electrochemical reactions in the plating tank to obtain a metal protective layer. The main source of electroplating wastewater is the cleaning water of the plating parts, the filtering water of the plating parts, the waste plating solution and the "running, running, dripping and leaking" caused by improper operation or poor management in the electroplating production process; in addition, there are wastewater treatment processes Discharge of self-owned water and drainage of laboratory tests. Electroplating wastewater mainly contains heavy metal ions such as chromium, zinc, copper, cadmium, lead, nickel, etc., as well as acids a...
