產品介紹：斜板、斜管統稱為淺池沉淀池，是建立在淺池沉淀原理基礎上的。
設有一理想沉淀池，池窖V，表面積A，池長L，寬=B，高=H，處理水量Q，停留時間t，沉降速度U0。則V=Qt，H=Uot，Q=Uot/H=U0A。
由(you)(you)淺(qian)池(chi)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)原(yuan)理(li)可(ke)知(zhi)：沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)效率(lv)(lv)僅為(wei)(wei)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)表面(mian)積(ji)的(de)(de)函數，而與(yu)水深(shen)無關。當(dang)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)容(rong)積(ji)為(wei)(wei)定值時，池(chi)子(zi)越(yue)淺(qian)則(ze)A值越(yue)大，沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)效率(lv)(lv)越(yue)高。所以，如(ru)果將(jiang)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)按高度(du)分(fen)隔為(wei)(wei)n層(ceng)(ceng)，即分(fen)隔為(wei)(wei)n個高度(du)為(wei)(wei)h=H/n的(de)(de)淺(qian)層(ceng)(ceng)沉(chen)(chen)(chen)(chen)(chen)降(jiang)單元，在(zai)Q不(bu)變的(de)(de)條件(jian)下，顆(ke)粒(li)的(de)(de)沉(chen)(chen)(chen)(chen)(chen)降(jiang)深(shen)度(du)由(you)(you)H減(jian)小到H/n，則(ze)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)中可(ke)被完全除去的(de)(de)顆(ke)粒(li)沉(chen)(chen)(chen)(chen)(chen)速(su)范圍由(you)(you)原(yuan)來(lai)的(de)(de)u ≥U0擴大到u ≥U0/n ，沉(chen)(chen)(chen)(chen)(chen)速(su)u<U0的(de)(de)顆(ke)粒(li)中能(neng)被除去的(de)(de)分(fen)率(lv)(lv)也由(you)(you)u/U0增大到nu/U0，從而使該(gai)沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)懸浮顆(ke)粒(li)去除率(lv)(lv)比原(yuan)來(lai)增大了n倍。顯然，分(fen)隔的(de)(de)淺(qian)層(ceng)(ceng)數越(yue)多，去除率(lv)(lv)也相應(ying)提高。將(jiang)這一(yi)原(yuan)理(li)可(ke)制成斜板或斜管沉(chen)(chen)(chen)(chen)(chen)淀(dian)(dian)(dian)池(chi)。
