6、y'sotherreportscompiledandreportedtowork;SBR工艺在生活污水处理中的应用研究摘要我国水资源十分短缺，人均水资源只有世界平均水平的1/4,水已成为未来制约国民经济发展和人民生活水平提高的重要因素。一方反面城镇缺水十分严重，一方面大量处理后城镇污水直接排放，既浪费了资源，又增加水体环境负荷。目前，推广使用污水处理的主要障碍之一是经济效益问题，因此要降低污水处理设施造价，降低能耗。在进行城市污水处理厂设计时，应根据目前水质情况，并考虑中、远期发展，合理的确定设计水质和处理工艺流程。城市生
7、活污水的处理方法有很多种。生物处理法以其运行管理费用及较好的处理效果，在污水（尤其是生活污水）处理领域中一直占主导地位。SBR工艺具有占地面积小、工艺流程简单、运行方式灵活、易于程控、对水质水量变化适应性强、去除有机物的同时具有良好的脱氮除磷等优点。随着电子和自动化技术的发展，该工艺已广泛应用于欧、美等许多国家的城市污水和各种工业废水的处理中。对于污水水质日益复杂的当今社会，SBR是一种较有发展前途的废水生物处理工艺。关键词：生活污水，SBR,去除有机物，脱氮除磷39/40responsibleforthedevelopm
