厌氧消化技术在日本有机废水和废弃物处理中的应用

Application of Anaerobic Digestion Technologies to Organic Wastewater and Organic Wastes Treatment in Japan

日本污泥厌氧消化始于1932年,目前污泥厌氧消化工程已超过300个,消化池总容积达210×104m3。目前,全日本共有300多座升流式厌氧污泥床反应器(upflow anaerobic sludgebed,UASB)和膨胀颗粒污泥床(expanded granular sludge bed,EGSB)处理厂,主要用于包括啤酒废水、软饮料废水、酿酒废水、食品加工废水和化工废水在内的高浓度有机工业废水的处理。总结了厌氧消化技术在日本有机废水和有机废弃物处理中的应用状况,以及运行参数。此外,对日本厌氧消化技术在厌氧膜生物反应器、产氢产甲烷两段发酵和沼气生物脱硫等方面的新进展也进行了介绍。

In Japan, anaerobic sewage sludge digestion began in 1932, and is now used in over 300 sewage treatment plants with a total digester volume of 210×10^4m^3 Over 300 upflow anaerobic sludge bed （UASB） and expanded granular sludge bed （EGSB） full-scale plants are now in operation for the treatment of industrial wastewaters with high concentration from beer, soft drink, liquor, food and chemicals production. The applications and parameters of anaerobic digestion technologies in Japan for organic wastewater and organic wastes treatment are summarized. Recent developments of anaerobic digestion technologies including anaerobic membrane bioreactor, hydrogen-methane fermentation and biological desulfurizatiou of biogas are introduced.
