摘　　要：通过研究间歇通风对固体废物的产酸和产甲烷阶段的分离及接种微生物加快固体废物稳定化速度的有效性,评价了污染物原位去除的可行性。结果表明:间歇通风有利于固体废物的产酸和产甲烷阶段分离,对固体废物的稳定具有积极的影响;用活性污泥接种微生物,加速了废物的稳定,提高了渗滤液的水质,CODCr的去除率达88%,ρ(BOD5) ρ(CODCr)由0 35降到0 12,总氮和NH4+的去除率分别达70%和80%以上,对重金属也有很好的去除。因此,在填埋场进行污染物原位去除是可行的。The availability of separating acid-production phase and methane-production phase through intermittent aeration, and accelerating stabilization of solid waste through inoculation was studied, and the feasibility of on-site removing pollutants was evaluated. The results indicate that intermittent aeration is favorable for two-phase separation and has positive impacts on the solid waste stabilization. Inoculation reduces waste stabilization time and improves leachate quality; the removal ratio of the COD_(Cr) is up to 88%; ρ(BOD_5)/ρ(COD_(Cr)) value decreases from (0.35) to (0.12;) removal efficiencies of total nitrogen and ammonium are up to over 70% and 80%, respectively; heavy metals can be removed effectively. Therefore, it is feasible to treat pollutants on-site by aeration and leachate recirculation.
