某商業(yè)洗衣店采用膜分離設(shè)備處理廢水（微濾/納濾）

Time：2018-11-15 | Click：191

商業(yè)洗衣店排放的廢水中含有大量的 BOD、COD、洗滌劑和表面活性劑。為了減少廢水的排放而不得不將一部分廢水回用，因此回用水中的上述污染物必須去除。廈門福美科技公司的膜分離設(shè)備，將納濾和微濾設(shè)備結(jié)合在一起，能夠?qū)U水中油脂、TDS、 TSS，洗滌劑和表面活性劑去除，系統(tǒng)的滲透產(chǎn)水則被循環(huán)回洗衣工藝中使用。系統(tǒng)設(shè)計(jì)：下圖的一套洗衣店廢水處理系統(tǒng)采用先微濾后納濾的兩級(jí)膜設(shè)計(jì)。其中微濾設(shè)備用于去除各種纖維、油脂、污垢；而納濾設(shè)備用于去除 TDS。洗滌劑和表面活性劑。微濾設(shè)備中有將近 50gpm 的濃水被循環(huán)回微濾設(shè)備進(jìn)口，其目的是為了提高微濾膜表面的切向流速以防止微濾膜表面污染。納濾設(shè)備的滲透水被循環(huán)回洗衣工藝中。
