立式移动地板发酵仓技术在崇明某污水厂的应用
- Title:
- Application of Vertical Mobile Floor Fermentation Bin in a Sewage Treatment Plant in Chongming District
- 摘要:
- 污泥好氧发酵是一种成熟的污泥处理处置技术，在污泥处理领域得到了广泛的应用。立式移动地板发酵仓技术与传统发酵设备相比，具有占地面积小、发酵设备密封性好、升温快等优点，适用于小规模污泥的好氧发酵。崇明区某污水处理厂污泥处理采用立式移动地板发酵仓技术，设计规模为10 t/d（污泥含水率为80%），处理后污泥含水率＜40%，成品可用作园林绿化肥料、培育土等。结合该工程实例，详细介绍了立式移动地板发酵仓技术的原理、工艺流程、系统组成、设计参数等。
- Abstract:
- Sludge aerobic fermentation is a mature sludge treatment and disposal technology, which has been widely used in the field of sludge treatment. As a new type of miniaturized sludge composting technology, the vertical mobile floor fermentation bin has small footprint, good sealing performance of the fermentation equipment, and rapid heating, compared with traditional fermentation equipment and is suitable for aerobic fermentation of small-scale sludge. The technology was adopted in the sludge treatment of a sewage treatment plant in Chongming District with design capability of 10 t/d (sludge water content was 80%). The treated sludge water content was less than 40%, which could be used as green fertilizer, cultivated soil, etc. Taking this project as an example, the principle, process flow, system composition and design parameters of vertical mobile floor fermentation bin technology was introduced in detail.
