The ODN specific denitrification equipment, through the specific action of denitrifying bacteria and biological enzymes, can denitrify nitrate nitrogen wastewater. The equipment's nitrate nitrogen removal efficiency is ≥90%, and the denitrification load can reach 1.0-2.0.kgNO3-N/m³·d，Especially suitableNO3-N 300～5000mg/LWastewaterSignificantly reduces denitrification carbon source.
Equipment Advantages:
l Denitrification load up to1.0-2.0 kgNO3-N/m³·d。
l High carbon source utilization rateC Source: TN ≈ 2:1 to 3:1.
l Low operation cost, denitrification cost is lower than that of conventional denitrification processes.30%～50%。
l Small footprint, easy operation, no maintenance required.
Application Range:
ODN denitrification equipment can be widely applied in the wastewater treatment of industries such as photovoltaic, stainless steel, nitric chemical, anodic oxidation, etc.
Engineering Case Studies：
Liaoning Chemical IndustryCompanyNitrate Wastewater Total Nitrogen3300 mg/L, treated to a first stage by the ODN denitrification unit, effluent total nitrogen 300 mg/L, followed by a second stage treatment to total nitrogen < 50 mg/L, meets discharge standards.
