概括

垃圾填埋场在早期无氧降解过程中迅速将微塑料 (MP) 释放到液中,并观察到碎片化. 液循环增加了MP的释放,但减少了总出口,同时有助于气味和MP控制.

科学领域:

环境科学环境科学
废物管理废物管理
污染控制污染控制

背景情况:

垃圾填埋场处理城市固体废物,排放气味和积累微塑料 (MP).
了解在早期无氧降解期间的MP释放对于填埋场管理至关重要.

研究的目的:

研究垃圾填埋场中微塑料释放和气味产生之间的关系.
分析液循环对微塑料释放和碎片化的影响.

主要方法:

监测垃圾填埋场液中的微塑料度和颗粒大小分布.
分析了微塑料释放和硫酸盐减少之间的相关性.
将循环中的微塑料释放与非循环的液系统进行比较.

主要成果:

在垃圾填埋的早期阶段,微塑料迅速释放到液中,在沉积物中积累.
液循环增加了微塑料度 (1.45倍),但减少了整体出口.
观察到微塑料的碎片化,较小的颗粒 (<0.5毫米) 显著增加.
微塑料释放和硫酸盐减少之间存在正相关性.

结论:

与最初的废物相比,垃圾填埋场的漏操作显著增加了微塑料的释放量.
液循环可以减轻总微塑料出口,尽管最初的释放峰值.
研究结果支持综合策略,用于管理垃圾填埋场的气味和微塑料污染.

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.
