TECHNICAL DEVELOPMENT FOR ACTIVATION OF SULFATE REDUCTION BACTERIA TREATING ACID MINE DRAINAGE AND ITS APPLICATION TO ACID MINE DRAINAGE TREATMENT SYSTEM

摘要

PURPOSE: An acidic drainage processing unit using the sulfate reducing bacteria is provided to satisfy the concentration condition of lactate which is a suitable condition for outgrowing the sulfate reducing bacteria and increase the amount of hydrogen sulfide which is an material generated by sulfate reducing bacteria, thereby increasing the efficiency acidic waste water treatment. CONSTITUTION: The acidic waste water treatment includes a sulfate reducing bacteria inhabitation layer(10) included in the sulfate reducing bacteria, a anaerobic swamp comprised of mixed stroma material by including the mushroom compost and oak waste wood, and a limestone(30) included on the lower part of the anaerobic marshland. The sulfate reducing bacteria inhabitation layer is the excrements of minor, chicken, or excrements of minor and chicken. The stroma material of anaerobic marshland comprised of oak waste wood 70~80 weight % which has low lactate exudation 0~0.01mM to maintain the lactate to be 0.03~0.04mM and mushroom compost 20~30 weight % comprised of mushroom from right after the harvest to 3 month.
