[0052] Microbial culture medium: (NH 4 ) 2 SO 4 3g / L, KCl 0.1g / L, KH 2 PO 4 3.5g / L, MgSO 4 ·7H 2 O0.5g / L, CaCl 2 2H 2 O 0.33g / L and FeSO 4 ·7H 2 O 0.018g / L, pH2.0
[0053] Additives: hydroxyethylidene diphosphonic acid, disodium hydroxyethylidene diphosphonate, dodecylbenzenesulfonic acid, crape myrtle leaf extract, lilac flower extract, lavender oil
[0054] Instructions:
[0055] (1) The microorganisms were 8.5×10 5 The concentration of each / mL was inoculated in the microbial culture solution. After culturing at 25°C for 24 hours, the color of the bacterial solution turned yellow. After testing, the concentration of Thiobacillus thiooxidans was 8.5×10 6 cells / mL, and the sulfuric acid content is 15%, stop the cultivation; add the additive to the above bacterial liquid at a concentration of 10g / L, mix well, and set aside.
