摘要: 本研究主要针对烟嘧磺隆和恶草酮等除草剂生产过程中产生的废母液，其具有成分复杂、可生化性差等特点。本文通过添加酸液，破坏废液中的有机高分子内部结构，生成部分不溶于水的沉淀，固液分离后液相采用多级反应(芬顿催化氧化、酸碱中和、絮凝沉淀)的工艺对废母液进行预处理。预处理后的废液再经过蒸发脱盐和生化处理后，达标排放。
Abstract: This study focused on the waste mother liquor produced in the production process of herbicides such as nicosulfuron and oxadiazon, which has the characteristics of complex composition and poor biodegradability. In this paper, by adding acid solution, the internal structure of organic polymer in the waste liquid was destroyed, and part of the precipitation insoluble in water was generated. After solid-liquid separation, the liquid phase was pretreated by multistage reaction (Fenton catalytic oxidation, acid-base neutralization, flocculation and precipitation). After pretreatment, the waste liquid will be discharged to the standard after evaporation desalting and biochemical treatment.
