Method for automatically controlling a rate at which a chemical feeding is provided to microbes in a filtration layer, and a denitrification of wastewater system.

摘要

Process and system for denitrification. The present invention relates to a process and system for the denitrification of wastewater.The process includes the steps of measuring a flow rate influence, to measure the concentrations of nitrates, nitrites, and dissolved oxygen in the wastewater and use the influential concentrations to determine a nominal amount of methanol to be provided for denitrification.The invention also includes the measurement of the effluent concentrations of nitrates and nitrites (that is, in the ~ 3 ~) and the optional use of effluent concentrations to adjust the nominal quantity of methanol is provided.
