3月18日，中國中冶所屬中冶華天工程技術有限公司以BOT模式運作的安徽省滁州市清流污水處理廠二期工程正式開工建設。
滁州(zhou)市(shi)清流污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)廠(chang)是(shi)中冶(ye)華天(tian)在滁州(zhou)承(cheng)擔的首個(ge)污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)廠(chang)BOT特許經營項目，建(jian)設總規(gui)模為10萬噸/日，分兩(liang)期(qi)(qi)(qi)(qi)建(jian)設，污(wu)(wu)(wu)(wu)水(shui)排(pai)放(fang)執(zhi)行(xing)國家一(yi)級B標準。中冶(ye)華天(tian)承(cheng)建(jian)的一(yi)期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)為5萬噸/日，已于2008年12月(yue)底正式商業(ye)運行(xing)。由于滁州(zhou)市(shi)近年來城(cheng)市(shi)快(kuai)速發展(zhan)，污(wu)(wu)(wu)(wu)水(shui)量(liang)迅速增加，2009年6月(yue)進入污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)廠(chang)的最高日污(wu)(wu)(wu)(wu)水(shui)量(liang)已達7.725萬噸/天(tian)，污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)廠(chang)已滿負(fu)荷運行(xing)。二期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)是(shi)在一(yi)期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)廠(chang)區內擴建(jian)，處(chu)(chu)理(li)(li)工(gong)(gong)藝(yi)與(yu)一(yi)期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)相(xiang)同，采用A2∕O污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)工(gong)(gong)藝(yi)，與(yu)一(yi)期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)并列布置，計劃于今(jin)年8月(yue)30日竣工(gong)(gong)投(tou)入使用。待二期(qi)(qi)(qi)(qi)工(gong)(gong)程(cheng)建(jian)成后，整個(ge)清流污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)廠(chang)可處(chu)(chu)理(li)(li)污(wu)(wu)(wu)(wu)水(shui)的范圍能(neng)涵蓋(gai)30平方公里(li)，日污(wu)(wu)(wu)(wu)水(shui)處(chu)(chu)理(li)(li)能(neng)力(li)將達10萬立(li)方米，污(wu)(wu)(wu)(wu)水(shui)集(ji)中處(chu)(chu)理(li)(li)率超(chao)過85%，年化學需(xu)氧量(liang)（COD）可削減0.98萬噸。
