A number of mitigation techniques exist to reduce the emissions of pollutant gases and greenhouse gases (GHGs) from anaerobic storage of livestock manure. Nanoparticle (NP) application is a promising mitigating treatment option for pollutant gases, but limited research is available on the mode of NP application and their effectiveness in gaseous emission reduction. In this study, zinc silica nanogel (ZnSNL), copper silica nanogel (CuSNL), and N-acetyl cysteine (NACL) coated zinc oxide quantum dot (Qdot) NPs were compared to a control lacking NPs. All three NPs tested significantly reduced gas production and concentrations compared to non-treated manure. Overall, cumulative gas volumes were reduced by 92.73%-95.83%, and concentrations reduced by 48.98%-99.75% for HS, and 20.24%-99.82% for GHGs. Thus, application of NPs is a potential treatment option for mitigating pollutant and GHG emissions from anaerobically stored manure.
有许多缓解技术可用于减少牲畜粪便厌氧储存过程中污染物气体和温室气体（GHG）的排放。纳米颗粒（NP）的应用是一种很有前途的减少污染物气体排放的处理方法，但关于 NP 的应用方式及其在减少气体排放方面的有效性的研究有限。在这项研究中，比较了锌硅纳米凝胶（ZnSNL）、铜硅纳米凝胶（CuSNL）和 N-乙酰半胱氨酸（NACL）包覆的氧化锌量子点（Qdot）NP 与缺乏 NP 的对照物。与未经处理的粪便相比，所有三种测试的 NP 都显著降低了气体产量和浓度。总的来说，HS 的累积气体体积减少了 92.73%-95.83%，浓度减少了 48.98%-99.75%，GHGs 的累积气体体积减少了 20.24%-99.82%。因此，NP 的应用是一种潜在的处理方法，可以减少厌氧储存粪便中污染物和 GHG 的排放。
