Industrial wastewater treatment microbial inoculum and preparation method thereof

Abstract

The invention provides an industrial wastewater treatment microbial inoculum. The microbial inoculum comprises the following components of sea-foam stone powder, modified clays, polyacrylamide, kaolin, cross-linked rectorite, chitosan, shells, lotus seed hulls, hazelnut shells, ginkgo shells, macadamia shells and compound microorganisms; a preparation method of the compound microorganisms includesthe steps that compound bacteria are inoculated into a culture medium, filtration is conducted to obtain a compound bacteria solution, and the compound bacteria solution is concentrated and dried toobtain the compound microorganisms; the compound microorganisms include bacillus licheniformis, actinomycetes, bacillus radicicola, wood-destroying fungi and arthrobacterium mixtures; the culture medium includes the following components of water, yeast extracts, glucose, dipotassium phosphate and sodium taurocholate. The industrial wastewater treatment microbial inoculum contains the compound microorganisms which decompose organic pollutants in sewage into water and carbon dioxide or convert the organic pollutants into nutrients of sewage treatment microorganisms, and use the nutrients for reproduction, and the reproduction process can just degrade the pollutants.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an industrial wastewater treatment bacterial agent and a preparation method thereof. Background technique [0002] Industrial sewage contains a large amount of heavy metals, which generally cannot be decomposed and destroyed, but can only transfer their existing positions and change their physical and chemical forms. At present, the treatment methods for heavy metal pollution are mainly physical and chemical methods, but the sewage treatment agents that are particularly effective for the treatment of wastewater containing heavy metals are not yet mature. At present, there are still many problems in sewage treatment plants, such as unstable water quality and high operating costs. The purified water needs to be disinfected by means of liquid chlorine, etc., which will lead to the death of a large number of microorganisms in the water body, resulting in the loss of self-puri...

Problems solved by technology

At present, the treatment methods for heavy metal pollution are mainly physical and chemical methods, but the sewage treatment agents that are particularly effective for the treatment of wastewater containing heavy metals are not yet mature. At present, there are still many problems in sewage treatment plants, such as unstable water quality and high operating costs. The purified water needs to be disinfected by means of liquid chlorine, etc., resulting in the death of a large number of microorganisms in the water, resulting in the loss of self-purification ability of the water body, and the phenomenon of secondary pollution due to the high chemical composition of the sewage treatment agent, etc.

However, simple microbial decomposition is slower than chemical treatment agents, and it is not easy to get quick results. How to combine microbial treatment with chemical treatment is a problem to be solved in the present invention.
