概括

废水中的微塑料污染日益令人担忧. 这项研究发现约旦一家工厂的清除效率为62%,但残留的塑料分子仍然存在,这凸显了更好的塑料管理的需要.

科学领域:

环境科学
水处理技术
污染控制

背景情况:

微塑料污染是一个重要的全球环境问题.
污水处理厂 (WWTP) 是MP进入水生生态系统的潜在途径.
在约旦等地区,关于PM度和清除效率的数据有限.

研究的目的:

量化约旦一家主要废水处理厂的流入水和废水中的微塑料度.
确定该设施的微塑料清除效率.
确定处理废水中存在的微塑料的类型和形态.

主要方法:

一个基于现场的研究,收集流入和废水样本.
使用湿 (38-1000μm),湿过氧化和光学显微镜.
根据形态学量化和分类微塑料颗粒.

主要成果:

影响的微塑料度平均为62. 6MP/ L.
污水中的微塑料度平均为23.8MPs/L.
获得了62%的整体微塑料清除效率,废水中纤维和碎片占主导地位.

结论:

污水处理过程部分去除了微塑料,但并没有消除它们.
处理过的废水中的微塑料对水生环境构成风险.
提高过技术和改善塑料废物管理对于减轻PM排放至关重要.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
