Abstract	Mechanical–biodehydrated–mechanical–biological (MBMB) treatment is an enhanced waste treatment technology implemented in China to solve the high moisture content and incomplete degradation of garbage. This study investigated the release of regulated odorous gases in various stages in MBMB treatment and evaluated the performance of the biofilter in controlling such gases. Trimethylamine was not detected throughout the whole treatment. Hydrogen sulfide, methyl mercaptan, and methyl sulfide were undetected after biostabilization was achieved. A very low concentration of 0.039 mg/Nm$^{3}$ styrene was detected on day 1 of biostabilization. After the MBMB treatment was administered, ammonia concentration decreased to 0.031 mg/Nm$^{3}$, which is lower than 0.155 mg/Nm$^{3}$ of the fresh household waste. Carbon disulfide concentration also decreased to approximately 50 %. The removal efficiencies of ammonia and hydrogen sulfide in the biofilter were 88.39 and 91.61 %, respectively. After biofiltration was completed, the outlet concentration of carbon disulfide was 0.017 mg/Nm$^{3}$, which was only 1/20 of the fresh household waste. Volatile organic compounds, namely styrene, methyl mercaptan, and methyl sulfide, were undetected at the outlet of the biofilter. Therefore, the MBMB treatment coupled with biofilter can efficiently remove household waste pollutants.
