摘　　要：利用实验室曝气沉砂池装置处理模拟生活废水,根据称量过滤所得悬浮物的质量分数,对曝气沉砂池处理工艺进行研究。认为曝气使废水中溶氧量大大增加,加速分解废水中的有机物,故悬浮物量比曝气前少;实验中沉淀时间越长,上层水悬浮物则越少,故沉淀20min后,所测得悬浮物最少。The simulated domestic wastewater was treated by the aerated grit chamber at laboratory. According to the suspended matter mass gained by filtration, the treatment process of the aerated grit chamber was studied.The results show that aeration makes the dissolved oxygen capacity in the wastewater increase obviously, organic matter in the wastewater can quickly be decomposed, so the suspended matter mass is less than that before aeration. In the experiment, the longer the precipitation time is,the lower the suspended matter mass is, after 20 min precipitation,the suspended matter mass reaches the minimum.
