Abstract

The invention discloses an immobilized microbial preparation, which is prepared by the following steps: S1. Cultivation and collection of Halomonas halophilus, Bacillus megaterium and Rhodotorula rhodotorula; S2. Preparation of immobilized microbial preparation: after mixing the bacteria Add it into the embedding agent, mix well and evenly, drop it into the calcium chloride solution at a uniform speed, solidify it at room temperature, and obtain the immobilized microbial preparation after vacuum freeze-drying; it also discloses the method of using the immobilized microbial preparation to treat pickle high-salt wastewater Method: The immobilized microbial preparation was added to the high-salt kimchi wastewater whose pH was adjusted to 6.5-7.5 at a ratio of 3-5% (w / v). The beneficial effects of the present invention are: it can degrade various pollutants in wastewater, and the degradation speed is fast, the ability is strong, the treatment efficiency is high, the stability is good, the process operation is simple, the production cost is low, and it is the solution to the problem of pickle wastewater pollution. effective way.

Description

technical field [0001] The invention relates to the technical field of pickle wastewater treatment technology, in particular to an immobilized microbial preparation and a method for treating pickle high-salt wastewater by using the preparation. Background technique [0002] Kimchi is a kind of vegetable food made from a variety of fresh vegetables, soaked in special salt water, and fermented by lactic acid bacteria. It is a favorite seasoning dish in our country. In recent years, the kimchi industry has developed vigorously, and kimchi products (pickled kimchi, seasoned kimchi, traditional pickled vegetables, etc.) are also sold well at home and abroad. However, with the rapid expansion of the industry scale, the accompanying environmental pollution problems are also intensifying, especially the problem that the discharge of a large amount of high-salt wastewater in this industry leads to the continuous deterioration of water quality, which has gradually attracted the attent...
