这项研究展示了一种新的方法来处理水中的有毒化. 较长的处理时间有效降解了污染物并降低了毒性,而较短的时间则增加了毒性.
科学领域:
- 环境化学环境化学
- 水处理技术水处理技术
- 生物催化剂是一种生物催化剂.
背景情况:
- 聚化是一种在水中发现的有毒工业污染物.
- 现有的治疗方法可能不足以完全修复.
- 研究一种使用固定酶和光催化剂的新方法.
研究的目的:
- 评估一种新的HRP-T玻璃系统,用于降解五二 (PCP) 和五二 (PBP).
- 评估液压保留时间 (HRT) 对污染物降解和毒性降低的影响.
- 进行处理副产品的毒性风险评估.
主要方法:
- 使用一个装有TiO2融合的玻璃柱子来支持固定过氧化酶 (HRP-Tglass).
- 紫外线照射激活了TiO2光催化,这反过来激活了HRP.
- 两个流速 (0.5和1.25毫升分钟-1) 被测试以改变HRT (20和8分钟).
- 在治疗前和治疗后,Microtox®,Hydra和CHO细胞测定测量了毒性.
主要成果:
- 较低的流速 (较长的HRT) 实现了97%的PCP和96%的PBP转化,其中65%的和70%的被去除.
- 较高的流速 (较短的HRT) 导致有限的脱和废水毒性增加.
- 在10小时内,HRP-Tglass系统表现出稳健性,有效性没有下降.
结论:
- 优化的HRT对于有效降解和降低基的毒性至关重要.
- 该HRP-Tglass系统提供了一个有前途的,强大的解决方案,用于水资源整治.
- 对降解副产品的毒性评估对于评估治疗疗效至关重要.
