Control method of chemical oxygen demand in waste water exhaust gas desulfurization apparatus and method for evaluating sterilization of wet exhaust gas desulfurization apparatus

摘要

Problem to be solved: to provide a method for controlling the chemical oxygen demand in the waste water desulfurization apparatus capable of quantifying the sterilization efficiency.A method for controlling the chemical oxygen demand in a waste water desulfurization apparatus isThe process of measuring the chemical oxygen demand in the waste water of the flue gas desulfurization apparatus isIf the measured chemical oxygen demand is below the reference value, drain is dischargedOn the other handThe process of detecting the amount of sulfur oxidizing bacteria in the wastewater by the PCR method using the primer pair for amplification of known genes of the sulfur oxidizing bacteria in the case of the reference value super isDepending on the amount of bacteria detectedAdjust the amount of oxidizing disinfectantSterilization process 3 andStep 4 for detecting the amount of bacteria in the wastewater after sterilizationIf the amount of bacteria detected again is less than or equal to the reference valueOn the other handStep 5 and steps 4 and 4 are repeated when the reference value is super.No selection
