Abstract:
Composing treatments of source separation (SS) household bio-organic waste and straw mixed in 10:1, 16 kinds of PAHs in source separation household bio-organic waste and compost production were determined by gas chromatograph/mass spectrograph (GC-MS) according to U.S.EPA 8270 standard method. Comparing 16 kinds of PAHs content, distributing and biodegradability,we evaluated the PAHs risk in farmland and discoursed the impact factors of PAHs biodegradability in household bio-organic waste composting. The results show that SigmaPAH16 contents in source separation household bio-organic waste and composting production is 2.19 and 1.96 mg/kg DM, and the contents of naphthalene, fluorene, phenanthrene, fluoranthene are relatively higher than others. The percent of these four organic pollutions is 79.76% and 81.76% in PAH16, respectively. The benzene loop number of these four organic pollutions is 2-3, and it' s easily degradable non-carcinogen in farmland utilization. SigmaPAH16 biodegradability is 25.88%, and the content of PAHs in SS household bio-organic waste compost production fits the farmland utilization criteria.
