Intermittent Aeration Black-Odorous Water Treatment

Optimized Aeration-Stop Ratio for N Removal

Simultaneously achieves high ammonia removal and enhanced total nitrogen removal via short-range nitrification-denitrification without external carbon source by tuning aeration-stop ratio.

Advantages

Stop duration perfectly negatively correlated with COD and NH4+-N removal (r = -1.0, -1.0); TN removal weakly positively correlated with aeration-stop ratio (r = 0.25)
