摘要
文章用自制的实验室快速渗滤系统模拟反应器对某校中水站的生活污水进行处理。研究结果表明,此套实验室模拟快渗处理生活污水系统对COD、TN、TP去除效果良好,壤土在三个周期对COD的去除率最大值为91.5%,TN为66.0%,TP为73.3%。由此试验得出最佳生活污水处理条件为壤土作为滤料,滤料高度为50cm,布水时间为2d淹水,4d落干。复合系统的处理效果优于单一介质的系统。
Self-made laboratory simulation constructed rapid infiltration system for school water stations in wastewater treatment was studied. Results showed that the system ran satisfactory in removing COD, TN and TP, with the maximum removal efficiency of COD as 91.5%, TN 66.0% and TP 73.3% in three cycles of surface soil. The best conditions for introduction of surface soil as a filter was determined, with filter height of 50cm, water distribution for two days flooded and four days drying. In addition, the effect of complex system was better than a single media system.
