四种小城镇污水处理工艺投资分析与探讨

Analysis and Discussion on Investments of Four Sewage Treatment Technologies in Small Towns

近年来我国小城镇污水处理厂处于大量建设的发展阶段,由于其建设、运营的复杂性和特殊性,采用常规污水处理工艺会造成投资偏大,运营费用偏高,难以持续稳定运行。介绍了四种较为适合小城镇发展的生物处理工艺(IBR生物处理工艺、人工快渗处理工艺、BL水循环处理工艺及生物转盘处理工艺),并分析了这四种工艺的工程投资。这四种处理工艺简单、运行管理方便、投资较少、经济效益较高,能够满足小城镇污水处理要求。

In recent years, small town sewage treatment plants are at the stage of development in China. Because of the complexity and particularity in the construction and operation, the conventional sewage treatment technologies can cause large investment and high operating costs and are difficult to op- erate continuously and steadily. Four biological treatment technologies suitable for the small towns, such as IBR biological treatment process, constructed rapid infiltration process, BL water cycle treatment process and RBC treatment process were introduced. The engineering investments of the four technologies were analyzed. They can meet the requirements of small town sewage treatment due to their simple process, convenient operation, less investment and high economic benefit.
