| 摘 要： | 为避免污泥产生的二次污染及充分利用污泥中的有效成分,对污泥进行堆肥处理是较好的污泥处理方法.考察了污泥含固率和pH值对污泥堆肥过程的影响.结果表明,污泥可堆肥的舍固率范围为25%～75%,最佳含固率为35%;可堆肥pH值为5.3～8.5.最佳pH值为7.4～8.3.

| Abstract: | With the development of world industry and the increasing of population in cities, the output of industrial wastewater and daily life wastewater have been increasing more and more, which leads to the increasing of sewage sludge greatly. In order to prevent the secondary pollution by sludge and make good use of it, composting is one of the good measures for municipal sewage sludge disposal. The effect of sludge solid contain rate and pH value were studied by experiments. The results showed that, the scope of sludge solid contain rate for composting was 25%-75%, the best one was 35%, and the scope of pH value for composting was 5.3- 8.5, the best one was 7.4-8.3. |
