Denitrification process and denitrification device

摘要

It regards process and the system which the sewage denitrification are done. This process measures inflow discharge, the nitrates in the sewage, measures the influx density of the nitrous acid salts and dissolved oxygen, includes the fact that the standard quantity of the methanol which is supplied to one for denitrification making use of this influx density is decided. Furthermore, this invention, nitrates and the nitrous acid salts (namely NO _x) utilizing outflow density appropriately in order to adjust the aforementioned standard quantity of the methanol which it is measured and is supplied and of outflow density and, is something which was inserted in consideration.
