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。
The effect of different proportion of filler and aeration on the initial temperature rise of sludge compost was studied. The results show that the proportion of high filler content of the heating rate was significantly faster than that of the filler content is low; high filler ratio of the reactor (filler accounted for 1/2 ~ 1/3) The stage can not supply oxygen; Low filler ratio and the proportion of refuse composting (filler accounted for 1/4 to 1/9 of the stack), due to the pores of the pile body less, you must ventilate adjust.
