概括

过氧化 (CaO2) 有效地减少了来自城市景观水的温室气体 (GHG) 排放,包括甲 (CH4) 和氧化 (N2O). 最佳的CaO2剂量可显著减轻这些有害排放,提供一种新的环境解决方案.

科学领域:

环境科学环境科学
水的化学水的化学
微生物学微生物学

背景情况:

城市水体的温室气体 (GHG) 排放是一个重大的环境问题.
过氧化 (CaO2) 用于水处理,但其对温室气体排放的影响尚不清楚.

研究的目的:

研究CaO2剂量对城市景观水中的甲 (CH4) 和氧化 (N2O) 生产的影响.
为了确定减轻温室气体排放的最佳CaO2剂量.

主要方法:

在无毒条件下,模拟的城市景观水被用不同剂量的CaO2处理.
分析了物理化学性质,感官质量和微生物种群 (脱细菌和甲基生物).
在50天的时间内量化了CH4和N2O的生产率.

主要成果:

通过抑制脱细菌,CaO2的添加改善了水质,并减少了N2O的产生.
CaO2选择性地影响了甲原体群落,增加了某些类型,而减少了其他类型.
最初,随着CaO2的剂量增加,CH4的产量会增加,但已经确定了最佳剂量.

结论:

二氧化是减少城市景观水中的CH4和N2O排放的有希望的试剂.
最佳的CaO2剂量为60g/m2,可以显著减少CH4 (41.21%) 和N2O (84.40%) 的排放.
这项研究提供了一种新的方法和方法,用于城市水系统的实际温室气体减排.

Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

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.
