摘　　要：选取青岛地区某高校人源粪水为研究对象,将人源粪水的COD、TS、固体回收率、氨氮作为分离后人源粪水的评价指标以确定人源粪水最优分离技术用于小型设备的开发.由于人源粪水的COD、BOD较高,直接进行好氧生化处理,将会加大处理难度,实验室采用聚合硫酸铁和1200万分子量的PAM作为进行人源粪水预处理的絮凝剂,将絮凝后的人源粪水的固形物除去.并在实验室条件下筛选出絮凝剂的用量和使用方法的基础上,结合人源粪水的物理性质和固液分离设备的特点,开发了絮凝后的人源粪水固液分离技术.With a university human fecal water in Qingdao area as the research object,this paper takes the COD,TS,solid recovery rate,ammonia nitrogen as the evaluation index of water,and determines the optimal separation technology of human manure for the development of small equipment.The higher COD and BOD in human fecal water will increase the difficulty of aerobic treatment,so the laboratory uses PFS and 12 million PAM as the molecular volume of human fecal water pretreatment flocculants to remove the solid matter from human feces after flocculation.In laboratory,the amount of flocculants and its application method are selected.With the physical properties of the source water,the characteristics of the solid and liquid separation equipment,the solid-liquid separation technology is developed.
