摘要
SBR废水处理技术是一种高效废水回用的处理技术,采用优势菌技术对校园生活污水进行处理,经过处理后的中水可以用来浇灌绿地、花木、冲洗厕所及车辆等,从而达到节约水资源的目的。
SBR废水处理系统方案要充分考虑现实生活中校园生活区较为狭小的特点,力求达到设备体积小,性能稳定,工程投资少的目的。废水处理过程中环境温度对菌群代谢产生的作用直接影响废水处理效果,因此采用地埋式砖混结构处理池以降低温度对处理效果的影响。同时,SBR废水处理技术工艺参数变化大,硬件设计选型与设备调试比较复杂,采用先进的PLC控制技术可以提高SBR废水处理的效率,方便操作和使用。
SBR废水处理系统分别由污水处理池、清水池、中水水箱、电控箱以及水泵、罗茨风机、电动阀门和电磁阀等部分组成,在污水处理池、清水池、中水水箱中分别设置液位开关,用以检测水池与水箱中的水位。
