摘要:
浓缩液是垃圾渗滤液处理过程产生的残余液，是实现垃圾渗滤液全量化处置的关键。针对青岛小涧西浓缩液处理工程在运行过程中存在的预处理不稳定、设备结垢，蒸发浓液产生量大、干化系统起沫无法结晶等问题，采用深度絮凝+化学软化预处理工艺可保证后端MVR蒸发及干化系统稳定运行，浓缩液处理能力明显提升，产浓率下降，连续稳定运行周期增加，干化系统恢复结晶减量能力。可见，采用“深度絮凝+化学软化+碳化硅膜+MVR蒸发+干化减量+焚烧协同”的工艺路线可实现渗滤液全量化处置。
Abstract:
The concentrate is the residual liquid generated from landfill leachate treatment process, which is the key to the full quantitation disposal of landfill leachate. Aiming at the problems of unstable pretreatment, equipment scaling, large amount of evaporation concentrate, and non-crystallization of drying system in Qingdao Xiaojianxi concentrate treatment project during operation, the deep flocculation and chemical softening pretreatment process is used to ensure the stable operation of the follow-up MVR evaporation and drying system. Thus the leachate concentrate treatment capacity is significantly improved, the concentration yield is reduced, the continuous stable operation cycle is increased, and the crystallization reduction ability of the drying system is restored. It shows that the full quantitation disposal of leachate concentrate can be achieved by adopting the process of deep flocculation, chemical softening, silicon carbide film, MVR evaporation, drying reduction, and coordinated incineration.
