Flue Gas Desulphurization and Denitrification Wastewater From FCC on Wastewater Treatment Influence and Solving Measures
The discharge of COD,pH,ammonia nitrogen and SS from flue gas desulfurization and denitrification wastewater in FCC unit often exceeds the operation index of the downstream wastewater treatment upgrading unit,threatening the stability of the total effluent outlet to reach the standard.Through the upstream and downstream make more communication,and take measures such as,control the pH control,adjustment of dosing,maintenance and mud replacement for the high-density clarifier arrangements,replacement of filter bags and when the waste heat boiler maintenance measures to strengthen adjustment in the source;at the end of wastewater treatment,reducing the load reduction,water balance,more monitoring,and ammonia nitrogen oxidation and subsequent bid-raising and modification optimization are adopted,to ensure the target of discharge.This article analyzes the problems in the pre-treatment of desulfurization and denitrification wastewater sources and wastewater treatment,and proposes measures to provide useful reference for design and operation personnel.
