Abstract :
Composing treatments of source separation (SS) household bio-organic waste and straw mixed in 10:1(m/m), 16 kinds of PAHs and AOX in source separation household bio-organic waste and compost production were determined by gas chromatograph/mass spectrograph (GC-MS) according with U.S.EPA 8270 standard method. Comparing 16 kinds of PAHs and AOX contents, PAHs distributing, PAH16 and AOX biodegradability in compost, evaluating the risk in farmland using and discussing the impact factors of PAHs biodegradability in household bio-organic waste composting. The results show that SigmaPAH16 contents in source separation household bio-organic and composting production is 2.19 and 1.96 mg/kg DM, the percents of Naphthalene, Fluorene, Phenanthrene and Fluoranthene are 79.76% and 81.76% in PAH16; the average content of AOX compound in HBW and in HBWC were 140 and 93.67 mg/kg dm respectively; the SigmaPAH16 and AOX biodegradability is 25.88% and 31.08,respectively. The content of PAHs and AOX in source separation household bio-organic waste compost(HBWC) production fits the farmland utilization criteria.
