斜板(ban)(ban)沉(chen)(chen)(chen)(chen)(chen)淀(dian)池(chi)的每兩塊平行斜板(ban)(ban)間相(xiang)(xiang)、有一個很(hen)淺的沉(chen)(chen)(chen)(chen)(chen)淀(dian)池(chi)。使(shi)被處理的水(或廢(fei)水)與(yu)沉(chen)(chen)(chen)(chen)(chen)降的污泥在沉(chen)(chen)(chen)(chen)(chen)淀(dian)淺層(ceng)中相(xiang)(xiang)互運(yun)動(dong)并分(fen)離(li)。根(gen)據其相(xiang)(xiang)互運(yun)動(dong)的力一向可分(fen)為同(tong)向流(liu)、異向流(liu) 和(he)側(ce)向流(liu)三種不同(tong)分(fen)離(li)方式。斜板(ban)(ban)沉(chen)(chen)(chen)(chen)(chen)淀(dian)池(chi)運(yun)用“淺層(ceng)沉(chen)(chen)(chen)(chen)(chen)淀(dian)”原理，縮(suo)短顆粒(li)沉(chen)(chen)(chen)(chen)(chen)降距離(li)，從而(er)縮(suo)短了沉(chen)(chen)(chen)(chen)(chen)淀(dian)時間，并且增加了沉(chen)(chen)(chen)(chen)(chen)淀(dian)池(chi)的沉(chen)(chen)(chen)(chen)(chen)淀(dian)面積(ji)，從而(er)提高了處理效率。
