城市污泥好氧发酵处理技术现状与对策

Current Status and Countermeasures of Aerobic Fermentation Technologies for Sewage Sludge Treatment in China

"好氧发酵+土地利用"是适合我国国情的污泥处理与处置途径。总结了几种典型好氧发酵工艺在我国的应用现状,同时分析了制约好氧发酵技术在污泥处理行业推广应用的因素,主要包括工艺及设备的标准化程度低、臭气污染、部分地区调理剂短缺、发酵产品未被公众广泛接受等,其中工艺及设备的标准化程度低是制约工艺推广的最主要障碍。

Aerobic fermentation plus land utilization is considered a suitable treatment and disposal method for sewage sludge in China. The applications of several typical aerobic fermentation processes were summarized. The factors restricting aerobic fermentation technologies in the sewage sludge treatment industry were analyzed. Limitations such as low standardization of the process and equipment, odor pollu- tion, amendment shortage and low acceptance of fermentation products were discussed. Among these, the lack of standardization of the process and equipment is the vital restrictive factor.
