TREATMENT OF ABSORBING SOLUTION FOR DENITRATING LOW CONCENTRATION NO-CONTAINING GAS

摘要

PURPOSE:To treat an absorbing solution used when relatively low concn. NO- containing gas is denitrated. CONSTITUTION:In a denitration method for oxidizing NO in a low concn. NO- containing gas to NO, by an alkaline absorbing solution, the alkaline absorbing solution for the low concn. NO-containing gas is treated so that the alkaline absorbing solution is treated with bacteria having denitrifying action to recover alkali.
