摘要
为实现污泥浓缩消化一体化,开发了新型内循环污泥浓缩消化(ICSTD)反应器,并进行了城市污水厂污泥处理试验。结果表明,在有机负荷为9. 68kgVS/(m3·d)、平均水力停留时间为3. 1d、污泥固体停留时间为54. 8d的条件下,污泥有机物分解率可达到79. 1%,排泥含水率达到90%,且上清液清澈,污泥消化与浓缩过程起到了相互促进的作用。
In order to achieve integration of sludge thickening and digestion, a new type internal recycle sludge thickening and digestion reactor was developed and test made on the sewage sludge treatment. The result shows that under the conditions of organic loading 9.68 kgVS/(m^3·d), average HRT 3.1 d, and SRT 54.8 d, the organic removal rate comes up to 79.1%, and water content in sludge up to 90% with clear supernatant. Sludge digestion and thickening can be stimulated by each other.
