[0002] The production process of high-nitrogen-utilization-efficiency nitrification-inhibiting compound fertilizer generates a large amount of wastewater containing suspended solids, dust, and organic impurities. Direct discharge of this wastewater easily causes environmental pollution, and water resources cannot be recycled, increasing production costs. Existing wastewater treatment equipment mostly adopts a fixed filtration and direct-spray dust suppression and deodorization structure, which suffers from problems such as low wastewater filtration efficiency, incomplete interception of suspended solids, uneven distribution of spray dust suppression, and mismatched coverage. It is difficult to maintain a dynamic balance between wastewater treatment and dust suppression efficiency across the entire work area, restricting the optimal realization of wastewater treatment efficiency. Furthermore, it cannot automatically adjust treatment parameters based on the concentration of impurities in the wastewater and the concentration of dust in the air, easily leading to over-spraying or under-treatment, affecting wastewater treatment effect and production environment safety.
