Negative pressure deodorization all-in-one machine of garbage station: the all-in-one deodorization machine is a new type of deodorization equipment formed by various deodorization processes such as Yiqing environmental protection combined with biological spraying process, photocatalytic oxidation, coupled catalytic process, high-pressure spray process, and ion fresh air negative pressure collection. By adopting various deodorization processes, different deodorization process equipment components can be added or removed, and the actual deodorization needs of various garbage transfer stations can be flexibly configured. It has excellent treatment effects on the complex odor gases generated by garbage transfer stations. Combined with our company's intelligent environmental sanitation management platform, it achieves real-time perception, monitoring, statistics, analysis, prediction and early warning, and proactive operation and maintenance, forming an effective combination of governance, monitoring, and operation.
