1.表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)物(wu)(wu)質(zhi)影(ying)響如水中(zhong)(zhong)(zhong)缺(que)少表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)物(wu)(wu)質(zhi)時(shi)(shi),小(xiao)氣(qi)(qi)(qi)(qi)泡(pao)(pao)總有突破(po)泡(pao)(pao)壁與大泡(pao)(pao)并合的(de)(de)(de)趨勢,從而(er)破(po)壞氣(qi)(qi)(qi)(qi)浮(fu)體穩定。此時(shi)(shi)就需要向水中(zhong)(zhong)(zhong)投(tou)加(jia)起(qi)(qi)泡(pao)(pao)劑(ji)(ji),以保證氣(qi)(qi)(qi)(qi)浮(fu)操作(zuo)中(zhong)(zhong)(zhong)氣(qi)(qi)(qi)(qi)泡(pao)(pao)的(de)(de)(de)穩定。所謂起(qi)(qi)泡(pao)(pao)劑(ji)(ji),大多數(shu)是由性(xing)(xing)(xing)(xing)非(fei)性(xing)(xing)(xing)(xing)分子(zi)組成的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)劑(ji)(ji),表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)劑(ji)(ji)的(de)(de)(de)分子(zi)結構符號般用0表(biao)(biao)示,圓頭(tou)端表(biao)(biao)示性(xing)(xing)(xing)(xing)基,易溶于水,伸向水中(zhong)(zhong)(zhong)(因(yin)為(wei)水是強性(xing)(xing)(xing)(xing)分子(zi));尾端表(biao)(biao)示非(fei)性(xing)(xing)(xing)(xing)基,為(wei)疏水基,伸人氣(qi)(qi)(qi)(qi)泡(pao)(pao)。由于同號電荷(he)(he)的(de)(de)(de)相(xiang)斥(chi)作(zuo)用,從而(er)防(fang)止氣(qi)(qi)(qi)(qi)泡(pao)(pao)的(de)(de)(de)兼并和破(po)滅,增強了(le)泡(pao)(pao)沫(mo)穩定性(xing)(xing)(xing)(xing),因(yin)而(er)多數(shu)表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)劑(ji)(ji)也是起(qi)(qi)泡(pao)(pao)劑(ji)(ji)。對有機(ji)污(wu)染(ran)物(wu)(wu)含量(liang)不多的(de)(de)(de)廢水行氣(qi)(qi)(qi)(qi)浮(fu)法處理時(shi)(shi),氣(qi)(qi)(qi)(qi)泡(pao)(pao)的(de)(de)(de)分散度(du)和泡(pao)(pao)沫(mo)的(de)(de)(de)穩定性(xing)(xing)(xing)(xing)可能(neng)時(shi)(shi)是必(bi)須的(de)(de)(de)(例如飲用水的(de)(de)(de)氣(qi)(qi)(qi)(qi)浮(fu)過(guo)濾)。但(dan)是當其濃度(du)超(chao)過(guo)定限度(du)后由于表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)物(wu)(wu)質(zhi)增多,使水的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)張力減小(xiao),水中(zhong)(zhong)(zhong)污(wu)染(ran)粒(li)子(zi)嚴重乳化(hua),表(biao)(biao)面(mian)(mian)(mian)(mian)電位(wei)增高,此時(shi)(shi)水中(zhong)(zhong)(zhong)含有與污(wu)染(ran)粒(li)子(zi)相(xiang)同荷(he)(he)電性(xing)(xing)(xing)(xing)的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)物(wu)(wu)的(de)(de)(de)作(zuo)用則轉向反面(mian)(mian)(mian)(mian),這時(shi)(shi)盡管起(qi)(qi)泡(pao)(pao)現象強烈,泡(pao)(pao)沫(mo)形成穩定;但(dan)氣(qi)(qi)(qi)(qi)粒(li)粘附(fu)不好,氣(qi)(qi)(qi)(qi)浮(fu)效果變低。因(yin)此,如何掌握好水中(zhong)(zhong)(zhong)表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)(huo)性(xing)(xing)(xing)(xing)物(wu)(wu)質(zhi)的(de)(de)(de)含量(liang),便成為(wei)氣(qi)(qi)(qi)(qi)浮(fu)處理需要探討(tao)的(de)(de)(de)重要課(ke)題之。2.混凝(ning)劑(ji)(ji)投加產生的(de)帶電絮粒(li)(li)對含有細分散親(qin)水(shui)(shui)性(xing)(xing)顆粒(li)(li)雜質(zhi)(例如紙漿、煤(mei)泥等)的(de)工業(ye)廢(fei)水(shui)(shui),采用氣浮法處理時(shi),除應(ying)用前(qian)述的(de)投加電解質(zhi)混凝(ning)劑(ji)(ji)行表(biao)面電中和方(fang)法外,還可(ke)向(xiang)水(shui)(shui)中投加(或水(shui)(shui)中存在(zai))浮選劑(ji)(ji),也(ye)可(ke)使(shi)顆粒(li)(li)的(de)親(qin)水(shui)(shui)性(xing)(xing)表(biao)面改(gai)變為(wei)(wei)疏水(shui)(shui)性(xing)(xing),并(bing)能(neng)夠(gou)與(yu)氣泡粘(zhan)附。當浮選劑(ji)(ji)(亦屬二親(qin)分子組成的(de)表(biao)面活性(xing)(xing)物)的(de)性(xing)(xing)端(duan)被吸附在(zai)親(qin)水(shui)(shui)性(xing)(xing)顆粒(li)(li)表(biao)面后,其非性(xing)(xing)端(duan)則(ze)朝(chao)向(xiang)水(shui)(shui)中,這樣具有親(qin)水(shui)(shui)性(xing)(xing)表(biao)面的(de)物質(zhi)即轉變為(wei)(wei)疏水(shui)(shui)性(xing)(xing),從而能(neng)夠(gou)與(yu)氣泡粘(zhan)附,并(bing)隨其上(shang)浮到水(shui)(shui)面。浮選劑(ji)(ji)的(de)種類很多(duo),使(shi)用時(shi)能(neng)否起(qi)作用,先(xian)在(zai)于(yu)它的(de)性(xing)(xing)端(duan)能(neng)否附著在(zai)親(qin)水(shui)(shui)性(xing)(xing)污染物質(zhi)表(biao)面,而其與(yu)氣泡結合力的(de)強(qiang)弱(ruo),則(ze)又取決于(yu)其非性(xing)(xing)端(duan)鏈(lian)的(de)長短。
處理(li):排(pai)放的(de)廢水(shui)(shui)(shui)先(xian)后流(liu)(liu)經粗(cu)細兩道格柵,主要(yao)去(qu)除(chu)較(jiao)大(da)懸浮物和(he)漂浮物,防止污水(shui)(shui)(shui)提(ti)升泵(beng)等機械設備堵塞。然后流(liu)(liu)入隔油(you)沉淀池(chi),廢水(shui)(shui)(shui)中含(han)有(you)泥(ni)(ni)(ni)沙等,這些可通過(guo)(guo)自然沉淀去(qu)除(chu),沉淀的(de)泥(ni)(ni)(ni)沙定(ding)期(qi)用污泥(ni)(ni)(ni)泵(beng)打(da)入污泥(ni)(ni)(ni)濃縮罐。油(you)脂(zhi)則漂浮在(zai)(zai)水(shui)(shui)(shui)面,可以(yi)人工撈(lao)出回收處理(li)。由于其(qi)廢水(shui)(shui)(shui)水(shui)(shui)(shui)質水(shui)(shui)(shui)量波動較(jiao)大(da),以(yi)確保(bao)(bao)后續處理(li)效果和(he)運行穩定(ding)性,在(zai)(zai)處理(li)工藝流(liu)(liu)程中設置調(diao)節(jie)池(chi),以(yi)均化水(shui)(shui)(shui)質水(shui)(shui)(shui)量。保(bao)(bao)證系(xi)統平穩運行。還可以(yi)通過(guo)(guo)調(diao)節(jie)池(chi)均化其(qi)本(ben)身的(de)、度,以(yi)使廢水(shui)(shui)(shui)的(de)pH值滿足后續處理(li)工藝的(de)要(yao)求。廢水(shui)(shui)(shui)中含(han)有(you)的(de)血污、油(you)脂(zhi)、油(you)塊等,通過(guo)(guo)混凝(ning)氣浮得到(dao)有(you)效的(de)去(qu)除(chu)。二處理:對(dui)于屠宰廢(fei)水(shui)中難(nan)降解(jie)、濃(nong)度較(jiao)高的(de)CODCr、BOD5,預處理過(guo)程中不能*去(qu)除(chu),故二處理采用生化(hua)處理,本設計采用水(shui)解(jie)化(hua)-好(hao)生物(wu)處理技(ji)術。水(shui)解(jie)化(hua)池主(zhu)要目的(de)將大分子有(you)機物(wu)分解(jie)成(cheng)小分子有(you)機物(wu),以便在好(hao)過(guo)程中步得(de)到(dao)去(qu)除(chu)。三處理:好(hao)處理后的(de)出(chu)水(shui),溢流到(dao)沉(chen)(chen)淀池中,沉(chen)(chen)淀后上(shang)清水(shui)入池,沉(chen)(chen)淀池中的(de)污(wu)(wu)泥定期用泥漿泵打入污(wu)(wu)泥濃(nong)縮罐中。
