一.实验目的
观察细格栅的作用：格栅在污水处理的作用原理是物理拦截。它分粗格栅、细格栅，对废水中的漂浮物、较大悬浮物进行拦截处理。细格栅主要去除水中一些细小的颗粒及悬浮物。
二.技术指标
1.处理水量：0.5m3/h。
2.工作电源：AC220V±10%、50Hz，单相三线制，功率200W，安全保护：具有接地保护、漏电保护、过流保护。 
3.电源线路及控制线的安装：须使用环保阻燃电气配线槽，规范整理符合国家标准，具有绝缘、防弧、阻燃自熄等特点，布线整齐，安装可靠，便于查找、维修和调换线路。
4.装置外形尺寸：1100mm×450mm×1400mm。
三.主要配置及参数
1.格栅池1只：透明有机玻璃材质、厚度10mm。细格栅1套：格栅间距2mm。
2.原水箱和清水箱1只：白色PP板、厚度10mm，水箱水箱底板上安装有放空阀，方便将水排净。
3.搅拌电机1台：功率25W、转速90rpm、不锈钢搅拌桨1套。
4.提升泵1台。
5.流量测量与调节：转子流量计，污水流量（量程100～1000L/h）。
6.304不锈钢台面、拉丝银双色板标牌标注主要组成单元，管路性质和水流方向标识，便于学生了解设备。
7.电源控制系统：双面亚光密纹喷塑电控箱1只、漏电保护器（德力西）、电压表、带灯自锁按钮开关（正泰）、线槽等组成，控制箱面板采用铝质凹字技术制作。
8.公元ERA配套连接管道和阀门、弯头。
9.不锈钢框架实验台（30*30mm不锈钢方管、配脚轮均为万向轮带禁锢脚）等组成。
