Factors affecting temporal H2S emission at construction and demolition (C&D) debris landfills

摘要: Abstract Odor problems associated with H 2 S emissions often result in odor complaints from nearby residents of C&D debris landfills, especially the early morning. As part a field study conducted on removal ability using different cover materials, daily and seasonal through soil layer were monitored at landfill to investigate factors affecting emissions. emission rates not constant, but varied seasonally, an average rate 4.67 × 10 −6  mg m −2  s −1 . During 10-month study, as concentration increased 140 ppm about 3500 ppm underneath testing cell, ranged zero maximum 1.24 × 10 −5 Continuous monitoring indicated that even changed over time throughout day, generally increasing morning afternoon, affected by moisture temperature. Laboratory experiments also effects content The results showed reduced retarding migration dissolving into water. due atmospheric dispersion, high may cause problems.
