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。
滁州市清流(liu)污(wu)(wu)水(shui)處理(li)(li)(li)廠(chang)是(shi)中冶(ye)華(hua)天在滁州承擔的首個(ge)污(wu)(wu)水(shui)處理(li)(li)(li)廠(chang)BOT特許經營項目，建(jian)(jian)(jian)設總(zong)規模為(wei)(wei)10萬(wan)(wan)噸(dun)/日(ri)，分兩期(qi)(qi)(qi)建(jian)(jian)(jian)設，污(wu)(wu)水(shui)排放執行(xing)(xing)國(guo)家一(yi)(yi)級(ji)B標準(zhun)。中冶(ye)華(hua)天承建(jian)(jian)(jian)的一(yi)(yi)期(qi)(qi)(qi)工(gong)(gong)程(cheng)為(wei)(wei)5萬(wan)(wan)噸(dun)/日(ri)，已于(yu)(yu)(yu)2008年(nian)(nian)12月底正式(shi)商業運行(xing)(xing)。由于(yu)(yu)(yu)滁州市近年(nian)(nian)來城市快速(su)發展(zhan)，污(wu)(wu)水(shui)量迅速(su)增加，2009年(nian)(nian)6月進(jin)入(ru)(ru)污(wu)(wu)水(shui)處理(li)(li)(li)廠(chang)的最(zui)高日(ri)污(wu)(wu)水(shui)量已達7.725萬(wan)(wan)噸(dun)/天，污(wu)(wu)水(shui)處理(li)(li)(li)廠(chang)已滿負荷運行(xing)(xing)。二期(qi)(qi)(qi)工(gong)(gong)程(cheng)是(shi)在一(yi)(yi)期(qi)(qi)(qi)工(gong)(gong)程(cheng)廠(chang)區內擴建(jian)(jian)(jian)，處理(li)(li)(li)工(gong)(gong)藝(yi)與一(yi)(yi)期(qi)(qi)(qi)工(gong)(gong)程(cheng)相同，采(cai)用(yong)A2∕O污(wu)(wu)水(shui)處理(li)(li)(li)工(gong)(gong)藝(yi)，與一(yi)(yi)期(qi)(qi)(qi)工(gong)(gong)程(cheng)并列布置，計劃于(yu)(yu)(yu)今(jin)年(nian)(nian)8月30日(ri)竣(jun)工(gong)(gong)投入(ru)(ru)使用(yong)。待二期(qi)(qi)(qi)工(gong)(gong)程(cheng)建(jian)(jian)(jian)成后(hou)，整個(ge)清流(liu)污(wu)(wu)水(shui)處理(li)(li)(li)廠(chang)可處理(li)(li)(li)污(wu)(wu)水(shui)的范圍能涵(han)蓋30平(ping)方公里(li)，日(ri)污(wu)(wu)水(shui)處理(li)(li)(li)能力將達10萬(wan)(wan)立方米，污(wu)(wu)水(shui)集中處理(li)(li)(li)率超過85%，年(nian)(nian)化(hua)學需氧量（COD）可削減0.98萬(wan)(wan)噸(dun)。
