Abstract

The invention provides a bacillus promoter for wastewater treatment and a preparation method thereof. The method is implemented by taking fruits as a fermentation substrate through the steps of material preparation and pretreatment; primary bacteria cultivation, and prior fermentation; secondary bacteria cultivation, and medium-term fermentation; coarse filtration, and late fermentation; deploying, and curing; fine filtration, concentration, filling and the like, so that a finished promoter product is obtained finally. The promoter provided by the invention can make bacilli become dominant bacteria in a biochemical reactor for sewage treatment, maintain the high activity of bacilli, and provide necessary trace elements for the germination and formation of bacillus spores.

Description

technical field [0001] The invention relates to a bacillus accelerator for sewage treatment and a preparation method thereof, belonging to the field of water treatment. Background technique [0002] With the vigorous development of my country's industry and the continuous improvement of people's quality of life, the amount of urban sewage generated is increasing. Due to the serious shortage of sewage treatment capacity in our country. As a result, nearly 50% of urban sewage is discharged into rivers, lakes or oceans without any treatment. The content of nitrogen, phosphorus and chemical oxygen demand (COD) in some water bodies has been seriously exceeded, which not only threatens the survival of aquatic organisms, but also affects human health. Although there are many sewage treatment methods at present, the research results and practical experience show that microbial water purification has become the most promising water purification method because of its high efficiency...
