空气质量监测空气质量监测
污水处理对污水处理的影响

背景情况:

增加的废水产生需要有效的处理,但废水处理厂 (WWTP) 的空气质量影响往往被忽视.
淡水保护区对于淡水保护至关重要,但也可能是大气污染物的来源,影响周围环境和人类健康.

研究的目的:

评估和比较两个不同的废水处理厂 (WWTP) 在西班牙托莱多的空气质量影响.
为了评估来自WWTP操作的气体排放,颗粒物和微量元素.
计算与WWTP空气污染相关的环境和健康风险指标.

主要方法:

在两个WWTP进行了为期6个月的空气质量监测研究:一个工业 (WWTP1) 和一个农村 (WWTP2).
测定了二氧化硫 (SO2),一氧化碳 (CO),氧化 (NOx),臭氧 (O3),挥发性有机化合物 (VOC),颗粒物 (PM2.5,PM10) 和微量元素 (TE) 的度.
计算环境和健康风险指标以量化污染影响.

主要成果:

温室气体处理器对SO2,CO和PM水平的贡献很小.
WWTP1的NOx水平接近监管值,并超过了人类健康保护的目标O3值.

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.

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Bioreactor Controls-I

Maintaining optimal conditions within fermenters is essential for maximizing microbial productivity and ensuring process efficiency. This lesson focuses on key parameters—temperature, foam, pH, carbon dioxide, oxygen, and pressure—and their precise measurement and control strategies in fermentation systems.Temperature ControlTemperature regulation is critical due to the exothermic nature of many fermentation processes. In small laboratory fermenters, temperature is commonly...
