Embodiment Construction
[0022] A kind of compound paint flocculant that adds bacterial cellulose shell-core structure, comprises the following steps:
[0023] (1) Separation and purification of strains
[0024] Put the paint wastewater in the later stage of treatment into a sterile Erlenmeyer flask, store it at 4°C, and sterilize the seed culture at 121°C. After cooling, take 100 μL of wastewater and inoculate it into 100ml of seed medium, and expand at a constant temperature of 37°C. Cultivate for 24 hours, then dilute the culture solution to 10, 10, 10, 10, 10, and 10 times respectively, and then spread each diluted bacterial suspension on the separation medium, culture at a constant temperature of 37°C for 24 hours, and pick out the cells with good morphology. After the initial isolation of the colonies, the selected bacteria were inoculated in the seed medium, incubated at a constant temperature of 37°C for 24 hours, the culture solution of each bacteria was diluted, separated and purified by str...
