Abstract

The invention discloses a high-efficiency denitrification compound microbial inoculum, and preparation and an application thereof, and belongs to the field of biotechnology. The microbial inoculum forwastewater treatment mainly includes six strains including nitrobacter sp, nitrosomonas sp, alcaligenes aquatilis, paracoccus nitrovorans, bacillus cereus, providencia vermicola and the like. A culture method includes enrichment, purification and enlarged culture of bacteria; the used microbial inoculum has the advantages of high denitrification efficiency, short domestication time, salt tolerance and the like, and is suitable for large-scale production. The obtained microbial inoculum can effectively treat high ammonia-nitrogen wastewater. The microbial preparation still has good denitrification ability under the condition of 2% total salt, solves the limitation of high-salt environment on a traditional biological denitrification method, and has broad application prospect and good socialbenefits.

Description

technical field

[0001] The invention belongs to the field of biotechnology, in particular to a high-efficiency denitrification compound bacterial agent, preparation and application thereof. Background technique

[0002] With the rapid development of fermentation, chemical and pharmaceutical industries, the treatment of high-concentration ammonia nitrogen wastewater has received more and more attention. Biological denitrification of wastewater in my country is currently a hot spot of concern and research in the field of water treatment. At present, the treatment of high ammonia nitrogen wastewater mainly includes physicochemical, biochemical and natural ecological treatment technologies. Biological denitrification technology has become one of the best denitrification methods due to its low investment and operating costs, simple operation, no secondary pollution, and high denitrification efficiency. thorough.

[0003] At present, there are two types of biological denitrifica...
