　　廢水特性：果蔬(shu)(shu)加(jia)(jia)工(gong)廢(fei)(fei)水(shui)(shui)(shui)(shui)組成較(jiao)為復雜，主(zhu)要由設備清(qing)(qing)(qing)洗廢(fei)(fei)水(shui)(shui)(shui)(shui)、消毒(du)清(qing)(qing)(qing)洗廢(fei)(fei)水(shui)(shui)(shui)(shui)、地面(mian)(mian)清(qing)(qing)(qing)洗水(shui)(shui)(shui)(shui)、果汁冷(leng)(leng)凝水(shui)(shui)(shui)(shui)、設備冷(leng)(leng)卻(que)水(shui)(shui)(shui)(shui)、空(kong)調冷(leng)(leng)卻(que)水(shui)(shui)(shui)(shui)地面(mian)(mian)清(qing)(qing)(qing)洗水(shui)(shui)(shui)(shui)及其他排(pai)放廢(fei)(fei)水(shui)(shui)(shui)(shui)等部(bu)分。果蔬(shu)(shu)加(jia)(jia)工(gong)廢(fei)(fei)水(shui)(shui)(shui)(shui)廢(fei)(fei)水(shui)(shui)(shui)(shui)以有(you)機污染(ran)物為主(zhu)，CODcr較(jiao)高，果蔬(shu)(shu)加(jia)(jia)工(gong)廢(fei)(fei)水(shui)(shui)(shui)(shui)中(zhong)(zhong)含有(you)大(da)(da)量漂(piao)浮物。對(dui)于果蔬(shu)(shu)垃(la)圾的處理，大(da)(da)量的果蔬(shu)(shu)垃(la)圾被(bei)傾倒到(dao)水(shui)(shui)(shui)(shui)體(ti)中(zhong)(zhong)，或(huo)者因堆(dui)(dui)積(ji)分解產(chan)生(sheng)(sheng)(sheng)的滲(shen)出(chu)液可(ke)能隨雨水(shui)(shui)(shui)(shui)流入水(shui)(shui)(shui)(shui)體(ti)，從而(er)導(dao)致水(shui)(shui)(shui)(shui)體(ti)污染(ran)。同時，果蔬(shu)(shu)垃(la)圾含水(shui)(shui)(shui)(shui)率(lv)較(jiao)高、易生(sheng)(sheng)(sheng)物降解，在堆(dui)(dui)放過程中(zhong)(zhong)會產(chan)生(sheng)(sheng)(sheng)大(da)(da)量惡(e)臭氣體(ti)，滋生(sheng)(sheng)(sheng)蚊(wen)蠅、傳播細菌(jun)，影響(xiang)環境衛(wei)生(sheng)(sheng)(sheng)。

　　處理工藝說明：果(guo)(guo)蔬(shu)(shu)加(jia)工廢(fei)(fei)水(shui)(shui)為(wei)高濃度(du)有(you)(you)機廢(fei)(fei)水(shui)(shui)，鑒于其生化性較好，生物(wu)處(chu)(chu)理(li)方法(fa)能(neng)夠將果(guo)(guo)蔬(shu)(shu)加(jia)工廢(fei)(fei)水(shui)(shui)處(chu)(chu)理(li)達標，故決定采用“水(shui)(shui)解酸化+生物(wu)接觸(chu)氧化”處(chu)(chu)理(li)工藝(yi)。該(gai)工藝(yi)不僅(jin)能(neng)有(you)(you)效(xiao)地去除(chu)果(guo)(guo)蔬(shu)(shu)加(jia)工廢(fei)(fei)水(shui)(shui)中的有(you)(you)機物(wu)、懸浮(fu)物(wu)，而(er)且運(yun)行可靠(kao)，管理(li)方便，處(chu)(chu)理(li)效(xiao)果(guo)(guo)好并且具有(you)(you)工藝(yi)能(neng)耗低，耐沖擊負荷(he)能(neng)力強，運(yun)行穩定，填料分段(duan)加(jia)密設(she)置不易(yi)堵塞(sai)，掛膜快等特點。
