Eliminating 98% of factory odors: A three-stage deodorization system for organic fertilizer plants.
In short: Odors in organic fertilizer plants mainly originate from peak levels of ammonia and sulfides produced during fermentation during composting and turning, as well as dust from the granulation workshop. A three-stage treatment system, combining Venturi scrubbing and pH-controlled chemical dosing, multi-layer biological filters using mature compost media, and activated carbon purification and adsorption, reliably achieves ≥98% deodorization efficiency, with ammonia emissions below 8 ppm, fully complying with GB 14554 standards. The total operating cost is less than RMB 1 per cubic meter of treated air, making it the most cost-effective solution to meet 2026 environmental regulations.
