實驗室廢水處(chu)(chu)理(li)工(gong)藝包括：物(wu)理(li)化(hua)學法、生(sheng)物(wu)法和物(wu)化(hua)—生(sheng)物(wu)法，其中物(wu)化(hua)法既可(ke)作為單獨的處(chu)(chu)理(li)工(gong)藝，也可(ke)作為生(sheng)物(wu)法的預處(chu)(chu)理(li)或后處(chu)(chu)理(li)工(gong)序。

學(xue)校(xiao)實(shi)驗室的廢水是(shi)如何處理？

對常用的好氧(yang)處理工藝(yi)進(jin)行(xing)比較，普通活性污泥法和(he)(he)生(sheng)(sheng)物轉盤存在工程投資高(gao)、工藝(yi)復雜(za)和(he)(he)運行(xing)管(guan)理不便(bian)等問題(ti);氧(yang)化溝(gou)雖處理效果好，剩(sheng)余污泥產(chan)生(sheng)(sheng)量少(shao)，但占(zhan)地面積(ji)大雖然只需設單(dan)一的反應池，即可完成(cheng)調節(jie)、曝氣、沉淀等功能，工藝(yi)流程簡(jian)單(dan)、占(zhan)地面積(ji)少(shao)，但該法操作管(guan)理嚴格，且大部(bu)分自控設備要(yao)依賴進(jin)口，造價高(gao);生(sheng)(sheng)物接觸氧(yang)化法容積(ji)負(fu)荷高(gao)、處理效果穩定(ding)，污泥產(chan)量少(shao)，無污泥膨脹現象，且耐沖擊負(fu)荷、運行(xing)和(he)(he)管(guan)理經驗(yan)成(cheng)熟。與前幾種生(sheng)(sheng)物處理法相比，生(sheng)(sheng)物接觸氧(yang)化法具有運行(xing)成(cheng)本低、結構緊湊、占(zhan)地少(shao)、投資省、操作管(guan)理方便(bian)等特點(dian)，更適合(he)于(yu)本工程的實際要(yao)求。

因此，本工(gong)(gong)(gong)(gong)(gong)程廢水(shui)(shui)處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)藝主體(ti)工(gong)(gong)(gong)(gong)(gong)藝選擇采用生(sheng)物接觸(chu)氧(yang)化(hua)(hua)法，同(tong)時，在處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)藝中增加(jia)酸化(hua)(hua)水(shui)(shui)解(jie)(jie)池，使(shi)進水(shui)(shui)中的(de)大分(fen)子有(you)機物變(bian)成小分(fen)子有(you)機物，提高(gao)廢水(shui)(shui)可(ke)生(sheng)化(hua)(hua)性，利(li)于(yu)好氧(yang)微生(sheng)物分(fen)解(jie)(jie)利(li)用，并去(qu)除部分(fen)懸浮物。此外(wai)，為(wei)保證(zheng)出水(shui)(shui)水(shui)(shui)質增加(jia)了(le)絮凝(ning)沉淀和(he)過濾的(de)后續處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)藝。zui終確定廢水(shui)(shui)處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)藝為(wei)：水(shui)(shui)解(jie)(jie)酸化(hua)(hua)+二段式接觸(chu)氧(yang)化(hua)(hua)+絮凝(ning)沉淀+過濾工(gong)(gong)(gong)(gong)(gong)藝的(de)廢水(shui)(shui)處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)藝。
