Product Description
High concentration wastewater denitrification process
The denitrification process is a technology specifically developed for high concentration wastewater, such as the sludge dewatering supernatant of industrial wastewater and digested sludge. Compared with other traditional denitrification processes, the significant advantage of denitrification process is its extremely low oxygen consumption, and the conversion into nitrogen does not require organic carbon. This process can be easily installed in existing factories.
The denitrification process can be divided into two stages
Stage 1: Ammonia nitrogen and oxygen undergo a nitrosation reaction to produce nitrite.
Nitrification reaction
Phase 2: Anaerobic ammonia oxidation reaction occurs between ammonia nitrogen and nitrite, generating nitrogen gas.
Anaerobic ammonia oxidation reaction
characteristic
◆ Low operating costs
◆ No need to add external carbon sources such as methanol or ethanol
◆ Reliable Performance
◆ 80% nitrogen removal rate
◆ Low sludge production
