Waste liquid treatment method and application thereof

The invention relates to the technical field of waste liquid treatment, and discloses a waste liquid treatment method and application thereof. The method comprises the step that the waste liquid is subjected to reduced pressure distillation treatment, and the waste liquid contains organic amine, water, thermal stability salt and acidic toxic gas dissolved in the waste water. The method provided by the invention not only can be used for effectively treating the waste liquid generated in the desulfurization amine liquid desalting treatment process, but also can be used for recycling organic amine, water, heat-stable salt and acidic toxic gas in the waste liquid, so that recycling and full utilization of resources are realized. 本发明涉及废液处理技术领域，公开了一种废液处理方法及其应用。该方法包括将所述废液进行减压蒸馏处理，其中，所述废液中含有有机胺、水、热稳定性盐和溶于所述废水中的酸性有毒气体。本发明提供的方法不仅能够有效处理脱硫胺液除盐处理过程中产生的废液，并且能够对其中的有机胺、水、热稳定性盐、酸性有毒气体进行回收，实现资源的回收和充分利用。
