1、成都信息工程學(xué)院環(huán)境工程專業(yè)學(xué)位論文印染廢水處理工程設(shè)計(jì)印染廢水處理工程設(shè)計(jì)摘要印染行業(yè)是工業(yè)廢水排放大戶，據(jù)不完全統(tǒng)計(jì)，全國(guó)印染廢水每天排放量為3106～4106m3。印染廢水具有有機(jī)物含量高、堿度大等特點(diǎn)，屬難處理的工業(yè)廢水。廢水的進(jìn)水水質(zhì)為CODcr：800mgL，BOD5：200mgL，SS：100mgL，pH：910，色度：500倍；出水水質(zhì)為CODcr：100mgL，BOD5：25mgL，SS：70mgL，pH：69，色度：

2、40倍。本次設(shè)計(jì)采用水解酸化氧化溝處理方法。廢水經(jīng)水解酸化后能降低后續(xù)處理的難度，氧化溝用以降低廢水中的CODcr和BOD5。計(jì)算出各種處理構(gòu)筑物的尺寸大小，并進(jìn)行合理的布局。廢水的處理成本為0.74元m3。關(guān)鍵詞關(guān)鍵詞：印染廢水；水解酸化；氧化溝；處理成都信息工程學(xué)院環(huán)境工程專業(yè)學(xué)位論文目錄論文總頁(yè)數(shù)：22頁(yè)1引言.............................................................
