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.

Abstract

The invention provides a bacterial agent for industrial wastewater treatment, which comprises the following components: sepiolite powder, modified clay, polyacrylamide, kaolin, cross-linked rectorite, chitosan, shell, lotus seed shell, hazelnut shell, ginkgo Shells, macadamia nut shells, and composite microorganisms; the preparation method of the composite microorganisms includes: inoculating the composite bacteria into culture medium for cultivation, filtering to obtain the composite bacteria liquid, concentrating and drying the composite bacteria liquid to obtain the composite microorganisms; wherein the composite bacteria include lichen Mixture of Bacillus, Actinomycetes, Rhizobium, Wood-rotting Fungus, Arthrobacter; culture medium includes the following components: water, yeast extract, glucose, dipotassium hydrogen phosphate, sodium taurocholate. The industrial wastewater treatment bacterial agent of the present invention contains composite microorganisms, which can decompose organic pollutants in sewage into water and carbon dioxide, or convert them into nutrients for sewage treatment microorganisms, and use these nutrients to reproduce, and the process can just degrade polluting substances.

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...
