Abstract

The invention provides a COD (chemical oxygen demand)-degrading fungicide agent and a preparation method thereof. The COD-degrading fungicide agent comprises compound fungicide liquid, a protective agent and a carrier, wherein the compound fungicide liquid comprises Aspergillus calidoustus liquid, trichoderma citrinoviride liquid, aspergillus niger liquid and rhizopus stolonifer liquid; the protective agent comprises skim milk powder, trehalose, calcium carbonate and glycerin. The preparation method comprises the following steps of (1) mixing the Aspergillus calidoustus liquid, the trichoderma citrinoviride liquid, the aspergillus niger liquid and the rhizopus stolonifer liquid into the compound fungicide liquid, adding the protective agent, and uniformly mixing; (2) crushing the carrier and treating by a 60 to 100-mesh sieve; (3) adding the crushed carrier into the compound fungicide liquid, uniformly mixing, pre-freezing, and drying, so as to obtain the fungicide agent. The fungicide agent has the advantages that the fungicide agent is used as a degradable microorganism, the strain is stable, the synergistic action is obvious, and the COD in sewage is favorably degraded.

Description

technical field

[0001] The invention belongs to the field of microbial preparations for water treatment, and in particular relates to a fungal agent for degrading COD and a preparation method thereof. Background technique

[0002] At present, the treatment of industrial, aquaculture and domestic wastewater plays an incomparable role in protecting the environment, but there are still many problems in the field of sewage treatment, such as the instability of industrial sewage in the treatment of water quality, and high operating costs. The purified water needs to be disinfected by injecting chlorine gas, etc., which will cause a large number of microorganisms in the water to die, so that the water body loses its original self-purification ability, and the chemical composition in the sewage treatment agent is high, which is easy It causes secondary pollution to the water body, etc., and the COD and ammonia nitrogen of the aquaculture sewage are super high.
