“…The AKP activity and TP removal rate of group E at 48 h were higher than those of the group with the added purification materials and the exogenous microorganisms ( Pundir et al, 2019 ; Zheng L. et al, 2019 ). The content of the genus Aspergillus at 48 h was higher than at 36 h, indicating that the purification materials assisted in the growth of certain exogenous microorganism environments and improved the growth of microorganisms associated with TP removal ( Cheng et al, 2019 ).…”

The study tested the water purification mechanism of the combination of microorganisms and purification materials via characteristic, enzymatic, and metagenomics methods. At 48 h, the removal rates of total nitrogen, total phosphorous, and Mn chemical oxygen demand in the combination group were 46.91, 50.93, and 65.08%, respectively. The alkaline phosphatase (AKP) activity increased during all times tested in the volcanic rock, Al@TCAP, and exogenous microorganism groups, while the organophosphorus hydrolase (OPH), dehydrogenase (DHO), and microbial nitrite reductase (NAR) activities increased at 36-48, 6-24, and 36-48 h, respectively. However, the tested activities only increased in the combination groups at 48 h. Al@TCAP exhibits a weak microbial loading capacity, and the Al@TCAP removal is primarily attributed to adsorption. The volcanic rock has a sufficient ability to load microorganisms, and the organisms primarily perform the removal for improved water quality. The predominant genera Pirellulaceae and Polynucleobacter served as the sensitive biomarkers for the treatment at 24, 36-48 h. Al@TCAP increased the expression of Planctomycetes and Actinobacteria, while volcanic rock increased and decreased the expression of Planctomycetes and Proteobacteria. The growth of Planctomycetes and the denitrification reaction were promoted by Al@TCAP and the exogenous microorganisms. The purification material addition group decreased the expression of Hyaloraphidium, Chytridiomycetes (especially Hyaloraphidium), and Monoblepharidomycetes and increased at 36-48 h, respectively. Ascomycota, Basidiomycota, and Kickxellomycota increased in group E, which enhanced the nitrogen cycle through microbial enzyme activities, and the growth of the genus Aspergillus enhanced the phosphorous purification effect.

“…Packing material is one of the main aspects affecting biofiltration's efficacy, playing a pivotal role in the growth of biofilm. The physical and chemical properties of different packing media determine the gas flow speed and specific surface area, which are vital factors influencing the removal efficiency achieved via biofiltration [111,112]. The particle size, bulk density, porosity and moisture content of packing material are also important factors that affect the long-term operational stability.…”

Mitigation Strategies of Air Pollutants for Mechanical Ventilated Livestock and Poultry Housing—A Review

et al. 2022

View full text Add to dashboard Cite

The fast development of large-scale intensive animal husbandry has led to an increased proportion of atmospheric pollution arising from livestock and poultry housing. Atmospheric pollutants, including particulate matter (PM), ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gases (GHG), as well as other hazardous materials (e.g., gases, bacteria, fungi and viruses), have significant influences upon the local atmospheric environment and the health of animals and nearby residents. Therefore, it is imperative to develop livestock and poultry housing mitigation strategies targeting atmospheric pollution, to reduce its negative effects on the ambient atmosphere and to promote sustainable agricultural production. In this paper, we summarize the various strategies applied for reducing outlet air pollutants and purifying inlet air from mechanical ventilated livestock and poultry housing. This review highlights the current state of knowledge on the removal of various atmospheric pollutants and their relative performance. The potential optimization of processes and operational design, material selection, and other technologies, such as electrostatic spinning, are discussed in detail. The study provides a timely critical analysis to fill the main research gaps or needs in this domain by using practical and stakeholder-oriented evaluation criteria.

“…The BTF was resilient that quickly recovered after shock loads. Cheng et al (2019) reported that a functional microorganisms (NSRP‐FM) in a biofilter setting was a better environment for microbial growth and the removal of gaseous n‐butyl acetate, than commercial polyurethane foam (PU‐foam) due to the slow release of nutrients from the packing material. Oliva et al (2019) compared the performance of a BTF and an algal‐bacterial tubular photobioreactor (TPBR) in removing toluene, VOC in air.…”
