The invention discloses a method for rapidly removing nitrate in a water body by using biochar immobilized denitrifying bacteria. The preparation method comprises the following specific steps: firstly, screening high-efficiency denitrifying bacteria to obtain a strain of pseudomonas stutzeri N3; and co-culturing the bacterial suspension of N3 with biochar, carrying out adsorption immobilization, and cleaning with normal saline to obtain the biochar immobilized denitrifying bacteria. The biochar is used as a carrier for immobilizing denitrifying bacteria, so that the method has the advantages of wide material source, simplicity in preparation, low cost, good treatment effect and the like, and resource utilization of wastes is realized. The biochar is used for immobilizing denitrifying bacteria, it is found that the removal effect on nitrate after immobilization is significantly better than simple biochar adsorption and denitrifying bacteria degradation. The method is of great significance for the rapid removal of nitrate in water bodies.

The present invention relates to a composite flora and a textile fiber preparation method by using the composite flora. The composite flora comprises bacillus sp. with a preservation number of CGMCC No.5971, rheinheimera tangshanensis with a preservation number of CGMCC No.5972, acinetobacter lwoffii with a preservation number of CGMCC No.5973, pseudomonas fluorescens with a preservation number of CGMCC No.5974, and Wickerhamomyces anomalus with a preservation number of CGMCC No.5975. The method comprises the following steps: preparing a bacterial liquid; treating raw materials; and preparing fibers, wherein fiber preparation comprises biodegradation, steam sterilization, fiber obtaining, drying, and combing. According to the present invention, the method does not pollute the environment, a waste liquid is directly converted into an organic fertilizer so as to achieve zero emission and zero pollution, the biological treatment process provides a protection effect for fibers, advantages of low production cost and high economic benefits are provided compared with the traditional chemical method, and characteristics of energy source saving and environmental protection are provided.
