Problems solved by technology

Because the microbial flocculation aid product can be used in combination with calcium chloride flocculant, it is suitable for a wide range of sewage and wastewater treatment, but because the bacteria are also bacteria that grow in non-saline soil environment, the microbial floc produced Coagulation aid products are not highly active when used to treat complex wastewater containing inorganic salts; and the time required to produce the microbial flocculation aid product is still long, and it is not easy to mass-produce; and the bacteria are purchased elsewhere, increasing the The cost of industrial production

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a microbial flocculation aid product and its preparation method, use method and application. Background technique [0002] Flocculation-assisted products are a kind of preparation or powder product that can precipitate other substances through adsorption and bridging. It is widely used in various fields of water treatment, such as sewage treatment, chemical precipitation, drinking water pretreatment, etc. Among them, microbial flocculation-assisted coagulation products have better flocculation-assisted coagulation effect, wider application range, and can be biodegraded, safe and non-toxic. Although the existing microbial flocculation aids can achieve better water treatment effects and are environmentally friendly, there are still problems such as difficulty in obtaining strains, harsh culture conditions, difficulty in mass production, or limited scope of application.
