摘　　要：试验研究了不同配比的填充料和通气状况对污泥堆肥起始升温的影响。结果表明 ,填充料含量高的配比升温速度明显比填充料含量低的配比快 ;高填充料配比的堆体 (填充料占堆料的 1 /2～ 1 /3)在起始升温阶段可以不进行氧气的供给 ;低填充料的配比和加入回流堆肥的配比 (填充料占堆料的 1 /4～ 1 /9) ,由于堆体的孔隙少 ,则必须进行通气量的调节。Ratio of the raw material and the bulking agent is an important parameter for sewage sludge composting. Different contents of bulking agent were studied in this experiment. Bulking agent typically affected on the original temperature raising The treatments with high percent of bulking agent would reach to high temperature more quickly than the low percent ones. The treatments with different content of bulking agent requests differently for oxygen. The high percent of bulking agent (1/2～1/3) did not needed less oxygen during the original phase, but the low percent was on the contrary.
