Problems solved by technology

[0006] The inventors have found in long-term research that the existing composite bacterial agents have limitations in varying degrees, such as poor applicability, and can only be used for some specific toxic wastewater or high-concentration wastewater with a single component; The production cost is too high, such as nitrifying bacteria; especially some compound bacterial agents have limited degradation ability and poor sustainability, and often require additional additions, thus increasing the cost

Abstract

The invention discloses a preparation method of a water treatment microbial inoculum. The method comprises the following steps: S1, taking bacteriophages of TTrichococcusflocculiformis, bacillus subtilis, paracoccus denitrificans, pseudomonas and saccharomycetes, adding a biological adhesive, performing stirring and mixing uniformly to prepare particles, and performing pre-drying to prepare composite bacterium particles with the water content of 3-8%; and S2, adding a small amount of water into the composite bacteria particles, diatomite, clay and activated carbon, uniformly performing mixingto prepare particles, and performing drying to obtain the treatment microbial inoculum. The composite microbial agent used in the invention can be suitable for various water quality environments, andhas a wide application range.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water treatment bacterial agent. Background technique [0002] Although my country's water resources and environmental protection has made positive progress, the situation is still grim. On the one hand, urban pollutant emissions far exceed the environmental capacity. On the other hand, in the breeding industry, under the action of spoilage bacteria, animal excrement will produce a large amount of toxic substances. [0003] Traditional water treatment agents usually refer to various chemical coagulation and flocculants used in water treatment, which can be divided into inorganic coagulation and flocculants and organic coagulation and flocculants. Commonly used chemical coagulation flocculants include: polymeric alumina (PAC, polyaluminum, basic aluminum chloride), aluminum sulfate, polyferric sulfate (EPS, polyferric, sulfur comb iron), ferric oxide, ferrous sulfate ( Green vi...
