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)市清(qing)流(liu)污(wu)(wu)水處(chu)理(li)(li)廠是中(zhong)冶華(hua)天在(zai)滁州(zhou)承擔的(de)(de)首(shou)個污(wu)(wu)水處(chu)理(li)(li)廠BOT特許(xu)經營項(xiang)目，建(jian)設總規(gui)模為(wei)10萬(wan)噸(dun)(dun)(dun)(dun)/日，分(fen)兩期建(jian)設，污(wu)(wu)水排放執行國家一(yi)(yi)級B標準(zhun)。中(zhong)冶華(hua)天承建(jian)的(de)(de)一(yi)(yi)期工(gong)(gong)(gong)程(cheng)(cheng)為(wei)5萬(wan)噸(dun)(dun)(dun)(dun)/日，已(yi)于2008年(nian)12月(yue)底正式商(shang)業(ye)運行。由于滁州(zhou)市近年(nian)來城市快速(su)發展，污(wu)(wu)水量迅速(su)增加，2009年(nian)6月(yue)進入污(wu)(wu)水處(chu)理(li)(li)廠的(de)(de)最高日污(wu)(wu)水量已(yi)達(da)7.725萬(wan)噸(dun)(dun)(dun)(dun)/天，污(wu)(wu)水處(chu)理(li)(li)廠已(yi)滿負荷運行。二期工(gong)(gong)(gong)程(cheng)(cheng)是在(zai)一(yi)(yi)期工(gong)(gong)(gong)程(cheng)(cheng)廠區(qu)內擴(kuo)建(jian)，處(chu)理(li)(li)工(gong)(gong)(gong)藝與一(yi)(yi)期工(gong)(gong)(gong)程(cheng)(cheng)相同，采用A2∕O污(wu)(wu)水處(chu)理(li)(li)工(gong)(gong)(gong)藝，與一(yi)(yi)期工(gong)(gong)(gong)程(cheng)(cheng)并列布(bu)置，計劃于今(jin)年(nian)8月(yue)30日竣工(gong)(gong)(gong)投(tou)入使用。待二期工(gong)(gong)(gong)程(cheng)(cheng)建(jian)成后，整個清(qing)流(liu)污(wu)(wu)水處(chu)理(li)(li)廠可處(chu)理(li)(li)污(wu)(wu)水的(de)(de)范圍能(neng)涵(han)蓋30平(ping)方(fang)公里(li)，日污(wu)(wu)水處(chu)理(li)(li)能(neng)力將達(da)10萬(wan)立方(fang)米，污(wu)(wu)水集中(zhong)處(chu)理(li)(li)率(lv)超過85%，年(nian)化(hua)學(xue)需氧量（COD）可削減0.98萬(wan)噸(dun)(dun)(dun)(dun)。
