AI Technical Summary
Existing autotrophic denitrification reactors are prone to scaling when treating wastewater with high hardness. Traditional high-flow-rate cleaning methods consume a large amount of water and are not very effective. Current technologies are unable to efficiently remove scale and nitrogen accumulation, which affects denitrification efficiency.
Design an ultrasonic-driven autotrophic denitrification reactor for sulfur. The reactor is an ultrasonic-driven autotrophic denitrification reactor for sulfur, which includes an inlet system, a reactor, an outlet system, and a descaling system. It uses components such as an ultrasonic generator, aeration pipe, blower, circulating electric valve, internal circulation pump, sludge discharge electric valve, and sludge discharge pump to remove scale and nitrogen through high-frequency vibration and restore the denitrification capacity of the packing.
It achieves efficient removal of scale and nitrogen, restores the denitrification capacity of the packing, improves the denitrification efficiency of the sulfur autotrophic system, and ensures long-term stable operation of the reactor.
