摘　　要：采用 5种调理剂 (木片、麦壳、玉米芯、稻壳和回流堆肥 )进行了中试规模的污泥堆肥 ,对含水率、有机质、总氮、氨氮、硝态氮、BOD5和比耗氧速率 (SOUR)等参数的变化进行了监测。研究结果表明 ,BOD5和SOUR指标适于评价采用不同调理剂的堆肥污泥稳定度。当BOD5<5 0mgO2 gVS和SOUR <0 .5mgO2 (gVS·h)时 ,可认为堆肥污泥达到了稳定和腐熟。Pilot scale test was carried out on the sludge composting by using 5 kinds of conditioner (wood chips,wheat hulls,rice hulls,corn cores,and recycled sludge compost) and monitoring was made on moisture content,organic matters total nitrogen,NH 3 N,NO 3 N, BOD 5 ,and specific oxygen uptake rate ( SOUR ).The results showed that BOD 5 and SOUR are suitable for evaluation of composted sludge stability by using various kinds of conditioner.The composted sludge is considered stable and mature if BOD 5 is less than 50 mgO 2/gVS and SOUR is less than 0.5 mgO 2/(gVS·h).
