“…Since these multiple sources are all related to MSW management, and some of them are located physically close to each other, individual odor fluxes overlap one another, making it difficult sometimes to precisely identify the source responsible for an odor release. This difficulty arises with various odorous compounds constituted of hydrogen sulfide, ammonia, and volatile organic compounds, including ketones, alcohols, chlorinated organic compounds, terpenes, organic sulfur compounds, alkanes, and aldehydes (Defoer et al, 2002;Rosenfeld and Suffet, 2004;Staley et al, 2006;Fang et al, 2012;Fang et al, 2013a). Overlapping fluxes of odor occur when several similar types of odor sources are located in close proximity, whether in a different or the same orientation to the odor receptors (Mao et al, 2013).…”

An integrated approach was applied to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities (an aerobic biological treatment plant and an anaerobic landfill site), identify their precise sources, and distinguish the interactive influences between them. Seven odor families were investigated, including alcohols, terpenes, carbonyls, aromatics, volatile fatty acids (VFAs), sulfur compounds, and ammonia. Principal components analysis, characteristic molecular ratios, and ternary diagrams were used to differentiate the interactive influence of the odor sources. Among typical biotic compounds, terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs. Ratios of p-cymene at sampling locations related to the biological treatment plant (aerobic status) were between 0.00 and 0.25, whereas those at landfill-related sampling points (anaerobic status) were between 0.25 and 1.0. The molecular ratio of terpenes was also found to be an appropriate means to differentiate between homologous and similar odor sources such as an aerobic biological treatment plant and anaerobic landfill.Implications: The aim of this work is to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities, identify their precise sources, and distinguish the interactive influences between them. The emission of gaseous pollutants greatly affects the living quality of nearby residents, and odor complaints are becoming a major problem. In this study we utilized various pretreatment and analytical methods to obtain integrated emission information of gaseous pollutants. The results showed terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs.

Abstract:Waste management is one of the most relevant problems of environmental protection. Landfills constitute an unavoidable component of the waste management system. The article discusses the problem of landfill odours. Reduction of waste tipping areas and temporary waste covering are the most efficient measures for reducing odours from landfills. The article presents the results of experimental tests on the use of building debris for the reduction of odours from landfills. Tests were performed by applying dynamic olfactometry. Upon covering waste with the building debris layer of 10 cm thickness odour thresholds fell from 51.0 to 79.7% compared with uncovered waste.

BACKGROUND: Trimethylamine (TMA), as a harmful nitrogenous gas, is potentially toxic to animals and human beings. In recent years, the emission of TMA has caused huge environmental problems. TMA is strongly toxic and carcinogenic and requires efficient treatment technology. Photocatalysis and photoelectrocatalysis (PEC) have attracted great interest because of their environmental friendliness and high efficiency. The key problem is how to construct high-efficiency systems and prepare high-activity catalysts.RESULTS: To eradicate TMA in air, an efficient electrochemical system with bio-anode and photocathode (g-C 3 N 4 -TiO 2 ) was designed. It removed TMA in air continuously and efficiently, for both single-cathode and double-cathode systems. This is the first report about TMA removal in such integrated g-C 3 N 4 /TiO 2 photocathode and bio-electrochemical system. Effects of reaction conditions were investigated, such as the TMA concentrations and flow rates. The highest efficiency for TMA removal was in an integrated PEC and microbial fuel cell (MFC) system with potassium persulfate (PS) activation. The double-cathode PEC-MFC-PS system could remove more TMA (1.9 g m −3 h −1 versus 1.3 g m −3 h −1 ) compared with the double-cathode PEC-MFC system. CONCLUSIONS: A novel TMA treatment system -PEC-MFC systemwas constructed, coupling PEC with MFC for continuous removal of TMA from air. Combined with activated PS, a PEC-MFC-PS system was designed and constructed and proved effective in oxidizing gaseous TMA and generating electricity at the same time, which has practical application prospects for the treatment of TMA pollution.
