Ｐ０３－０３快速砂滤池空气反洗机理及其影响海老江邦雄，笠原伸介（北见工业大学工学部）本文研究了中试过滤装置上的快速砂滤池空气反洗的机理及其影响，结果表明在开始不稳定期过滤池中沉积的混浊物的排出导致水从滤床中置换，当空气速度在３０─７０Ｎｍ￣３／ｈ，容...
P03-03 Rapid sand filter air backwashing mechanism and its impact Hai Dang Gang Bangxiong, Kasahara Nobuhiro (Kitami University of Technology Department of Engineering) This paper studied the pilot filter device on the rapid sand filter air backwash mechanism and its results show that The discharge of opacity deposited in the filter tank at the beginning of the instability results in the replacement of water from the filter bed when the air velocity is between 30 and 70 Nm³ / h.
