大學(xué)學(xué)生公寓洗漱廢水回用分析與探討

1、1大學(xué)學(xué)生公寓洗漱廢水回用分析與探討摘要：隨著高校的擴(kuò)招，校區(qū)人員的增多，高校已經(jīng)成為城市用水大戶，水質(zhì)成分簡(jiǎn)單，易于處理的特點(diǎn)，非常適合建設(shè)中水回用系統(tǒng)。中水回收利用是污水資源化的一種重 要方法，在高校區(qū)啟用中水回用系統(tǒng)，對(duì)我國(guó)的環(huán)境保護(hù)、水資源保護(hù)、水污染防治、經(jīng) 濟(jì)可持續(xù)發(fā)展都起到了至關(guān)重要的作用，具有明顯的經(jīng)濟(jì)效益、社會(huì)效益和環(huán)境效益。參 考了國(guó)內(nèi)外高校中水回用實(shí)例，本文利用序批式活性污泥工藝(SBR)處理甘肅農(nóng)業(yè)大學(xué) 18#學(xué)

2、生公寓樓洗漱廢水的工藝流程、特點(diǎn)、主要構(gòu)筑物設(shè)計(jì)參數(shù)及主要的技術(shù)經(jīng)濟(jì)指 標(biāo)，在技術(shù)經(jīng)濟(jì)上做了可行性分析。該工藝對(duì)洗漱廢水中 COD,BOD,SS 有較高的去除率,處 理后出水用于學(xué)生公寓沖廁,其水質(zhì)符合中華人民共和國(guó)《生活雜用水水質(zhì)標(biāo)準(zhǔn)》(GJ／ T48--1999)回用水標(biāo)準(zhǔn)的要求。該項(xiàng)技術(shù)由于設(shè)備形體小、工藝單一，原管道改變不大， 因而便于改建施工。關(guān)鍵詞：中水回用；洗漱廢水；高校；公寓樓 Washing wastewater re
