腐殖活性污泥工艺在日本和韩国的应用

Application of Humus Activated Sludge Process in Japan and the Republic of Korea

腐殖活性污泥工艺是在传统活性污泥工艺的基础上增加了填充腐殖土填料的生物培养装置,用于改善活性污泥特性,提高处理效果的新型污水处理方法。自20世纪80年代起,日本已成功地将该工艺应用于岛内住宅小区污水净化站、山之内水质净化中心、鸟栖市饭田地区和永吉地区农田排水处理站等多个污水处理厂,在韩国也已有200多个污水处理厂应用了该技术。运行结果表明,该工艺具有脱氮除磷效果好、污泥产量低、污泥脱水性好和污泥不产生臭气等显著优点。

The humus activated sludge process with microorganism cultivation reactor filled with humus soil pellets on the basis of traditional activated sludge technology is a new sewage treatment method to improve sewage treatment efficiency. Since 1980s, the humus activated sludge process is successfully employed in Shimauchi Housing Complex of Matsumoto City, Yamanouchi Sewage Treatment Center and Sewage Treatment Facility at Nagayoshi Agriculture Hamlet, Japan and is applied in more than 200 sewage treatment plants in the Republic of Korea. The operating results show that the process has advantages of excellent performance of nitrogen and phosphorus removal, low sludge production, good sludge dewaterability and no odor release.
