Reactors and methods for the culture, bio oxidation and / or mass transfer of microorganisms and / or local practical microorganisms in Mineral Leachates

摘要

The reactor consists of the following parts: (a) a cylindrical height / diamond ratio of 1.5 to 2.5, or even 3; (b) a diamond ratio of the base equal to or slightly higher than the taro cap of the reactor's base, a / h of the base between 9 and 11; (c) the reactor's primary and secondary vibration systems; (d) serpentin; (e) Air and CO2 mixture distribution system; (f) aerosol near the base (a);(g) Output from the reactor to the secondary disturbance system and the inlet from the secondary disturbance system to the reactor; (H) input basic pH solution, acid-base solution, culture medium, energy and safety source and a vent; (I) safety output, sampling and drainage; (J) sensor elements for pH, O2 dissolution, potential EH and liquid height; (k) elements used to determine flow and / or mass into the reactor; (L) dissolved O2 control system, pH, potential EH and reactor volume; and (m) input control system for air and CO2 mixtures. The method comprises the following steps: partially filling the reactor with the culture medium;Control pH between 1.5-2.5; start (E) 0.5-3% of CO2 by volume; inject energy into reactor; add microorganisms; operate reactor in Bach mode until microbial concentration exceeds 1x108 cells / ml; constantly changing; and Removal and maintenance of microbial concentration by secondary vibration control
