微電(dian)解法的影響因素

停留時間

停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)(HRT)也是鐵炭微電(dian)解(jie)工藝(yi)設計的一個主要影響因素，停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)的長(chang)(chang)短決定了氧(yang)化(hua)還原等作用時(shi)間(jian)(jian)(jian)(jian)的長(chang)(chang)短。停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)越長(chang)(chang)，氧(yang)化(hua)還原等作用也進行得越徹底，但由于停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)過長(chang)(chang)，會(hui)使(shi)鐵的消(xiao)耗量增(zeng)加，從而使(shi)溶出(chu)的Fe”*大量增(zeng)加，并氧(yang)化(hua)成為(wei)(wei) Fe3t，造成色度(du)增(zeng)加及后續(xu)處理的種(zhong)種(zhong)問題(ti)。所(suo)以停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)并非越長(chang)(chang)越好(hao)，而且對各(ge)種(zhong)不同(tong)的廢(fei)水(shui)，因其成分(fen)不同(tong)，其停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)差異也較大，短則(ze) 10~15 min，長(chang)(chang)則(ze)達 7~8h，因此，最佳(jia)停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)應(ying)通(tong)過試驗確定。建議設計參數:染料廢(fei)水(shui)停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)為(wei)(wei)30min，硝基苯(ben)廢(fei)水(shui)停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)為(wei)(wei)40~60min，制藥生產廢(fei)水(shui)停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)為(wei)(wei)4h，含油廢(fei)水(shui)停(ting)(ting)(ting)(ting)(ting)留(liu)(liu)時(shi)間(jian)(jian)(jian)(jian)為(wei)(wei)30~40 min。

停(ting)(ting)留(liu)(liu)時(shi)(shi)間(jian)(jian)(jian)還(huan)取決于進水(shui)(shui)的(de)(de)初始(shi)(shi)pH，進水(shui)(shui)的(de)(de)初始(shi)(shi)pH較(jiao)低(di)時(shi)(shi)，則停(ting)(ting)留(liu)(liu)時(shi)(shi)間(jian)(jian)(jian)可以相(xiang)(xiang)對(dui)取得短一點;相(xiang)(xiang)反，進水(shui)(shui)的(de)(de)初始(shi)(shi)pH 較(jiao)高時(shi)(shi)，停(ting)(ting)留(liu)(liu)時(shi)(shi)間(jian)(jian)(jian)也(ye)應相(xiang)(xiang)對(dui)的(de)(de)長(chang)一點。停(ting)(ting)留(liu)(liu)時(shi)(shi)間(jian)(jian)(jian)還(huan)反映了(le)鐵屑用量，停(ting)(ting)留(liu)(liu)時(shi)(shi)間(jian)(jian)(jian)長(chang)也(ye)就是說單位廢水(shui)(shui)的(de)(de)鐵屑用量大。兩(liang)個參數可以相(xiang)(xiang)互校核，共(gong)同控制。
