【正文】 ，明確了廢水的處理辦法，為此我們受貴單位的委托，對(duì)該污水進(jìn)行治理工藝設(shè)計(jì)，設(shè)備的制造及工程預(yù)算，供貴方選用。根據(jù)貴公司的情況，擬建一座 2880m3/d 污水處理設(shè)施，建后排放水達(dá)到《紡織染整工業(yè)水污染排放標(biāo)準(zhǔn)》(GB428792) 的一級(jí)要求。 4, less land occupation, low running costs。s image, improve the pany39。經(jīng)過處理的出水水質(zhì)好，能夠滿足 GB428792《紡織染整工 業(yè)水污染排放標(biāo)準(zhǔn)》一級(jí)要求，達(dá)標(biāo)排放。由于 廢水的有機(jī) 負(fù)荷不高，可生化性差，色度較高，綜合經(jīng)濟(jì)，技術(shù)和環(huán)境等因素，本工藝主要采用中和 +厭氧+好氧處理。I / 65目錄摘要
