1、摘 要建筑小区主要是指居住区、疗养院、商业中心、机关学校等具有几种(或一种)功能的、相对独立的区域,其排水系统一般不在城市市政管网覆盖范围之内。小区污水属于生活污水范畴,一般水量较小,在我国通常把设计规模小于4000m3/d的污水处理称为小区污水处理。小区污水一般水量、水质变化较大,污染物浓度比城市污水低,可生化性好,因而易于处理,并通过消毒处理可回用,节约水资源。本设计要求处理水量为500t/d的小区生活污水(以居住小区为背景),设计方案采用序批式间歇活性污泥法。SBR是序列间歇式活性污泥法(Sequencing Batch Reactor Activated Sludge Process)
2、的简称,是一种按间歇曝气方式来运行的活性污泥污水处理技术,又称序批式活性污泥法。SBR的技术关键是运行周期T的控制,采用时间分割的操作方式替代空间分割的操作方式,非稳定生化反应替代稳态生化反应,静置理想沉淀替代传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作,SBR技术的核心是SBR反应池,该池集均化、初沉、生物降解、二沉池等功能于一池,无污泥回流系统。应用序批式活性污泥法工艺,使出水水质达到城镇污水处理厂新污染物排放标准(GB18918-2002)标准的要求,并通过消毒回用,达到“零”排放目的。可作为中型楼盘生活污水处理工程的技术参考。关键字:小区生活污水处理,SBR,回用bAbstr
