Abstract
Disclosed is a device and method for efficiently treating nitrogen and phosphorus pollutants in mariculture wastewater, falling within the technical field of mariculture tailwater treatment. According to the method, in a nitrogen removal functional zone, modified agricultural waste is combined with elemental sulfur particles, and sulfur-reducing bacteria utilize carbon sources slowly released from the waste to reduce elemental sulfur to Sor Sutilized by sulfur-oxidizing bacteria, achieving sulfur transformation. The present disclosure solves the problems that, during treating mariculture tailwater using sulfur autotrophic denitrification technology, the low solubility of elemental sulfur particles and high dissolved oxygen concentration in the tailwater result in low utilization rate of elemental sulfur and poor nitrogen and phosphorus removal efficiency.
