吡唑酮生产中高盐废水处理与资源化利用一体化技术方案设计OACHSSCD

The treatment and resource utilization of high-salinity,high-organic wastewater have become a critical bottleneck restricting the green and sustainable development of the fine chemical industry.Based on this,taking the high-salinity wastewater generated during the production of pyrazolone,an organic pigment intermediate,as the research subject,and addressing issues such as its complex composition,high cost of traditional treatment methods,and severe resource waste,a comprehensive technical scheme of"wastewater treatment-resource recovery-product production"is systematically designed.The aim is to convert pyrazolone waste salt rich in nitrogen and sulfur nutrient elements into high-value compound fertilizers,achieving the resource and high-value utilization of waste.The research fully covers all technical links in the entire industrial chain,including optimization of source production process,selection of efficient desalination technologies,configuration of key equipment and formula optimization for compound fertilizer production,as well as the construction of an integrated intelligent monitoring system and the establishment of a technology demonstration area.This scheme can provide technical references for the treatment and resource utilization of high-salinity wastewater in the chemical industry,and has important demonstration significance for promoting industry energy conservation,emission reduction,and developing circular economy.
