【正文】 ulation process, the treatment effect was better than the traditional process, BOD, COD, the SS has a good treatment effect, and has low energy consumption, sludge production is less features, and excess sludge can be dehydration. Set after coagulation and sedimentation, sedimentation tanks, as a tertiary treatment, to obtain better water quality, wastewater discharge standards. Technical and economic analysis of this scenario, the total investment of 116 million wastewater treatment cost is / m3, has a good economic and social benefits. And land conservation, and increase afforestation, the idea of reducing energy consumption in the design to be fully practice, in line with the requirements of a new era of environmental protection. Keywords: printing and dyeing wastewater 。 經(jīng)技術(shù)經(jīng)濟(jì)分析， 此方案投資總額 116 萬(wàn)元，廢水處理成本為 元 /m3，有著良好的經(jīng)濟(jì)效益和社會(huì)效益。經(jīng)過(guò)方案比選，本設(shè)計(jì)采用 水解酸化 接觸氧化 混凝工藝 ， 其處理效果明顯優(yōu)于傳統(tǒng)工藝，對(duì) BOD、COD、 SS 有很好的處理效果，并具有能耗低、產(chǎn)泥量少的特點(diǎn)，且剩余污泥可直接脫水。 印染廢水具有色度高， COD、 BOD 含量高，成分復(fù)雜，水質(zhì)、水量變化劇烈等特點(diǎn)。河海大學(xué)環(huán)境工程畢業(yè)設(shè)計(jì) 第 1 頁(yè) 共 66

紡織染整工業(yè)水污染物排放標(biāo)準(zhǔn) 》（ DB 32/6702022）中規(guī)定的排放的要求，即 COD≤100mg/L，BOD≤25mg/L， SS≤70mg/L，色度 ≤40 度， pH 為 6~9， NH3N≤15mg/L。因?yàn)橛∪緩U水屬 于難降解的廢水，所以本設(shè)計(jì)采用水解酸化提高廢水的可生化性。沉淀池后設(shè)置混凝沉淀池，作為三級(jí)處理，可獲得較好的出水水質(zhì)，使廢水達(dá)標(biāo)排放。且節(jié)約用地、提高綠化、降低能耗的理念在設(shè)計(jì)中得到充分的實(shí)踐，符合新時(shí)代環(huán)保的要求。 hydrolysis acidification 。
