一座(zuo)現代化的綠色(se)環(huan)保鋼鐵(tie)強企(qi)正在宜居城市山(shan)東(dong)省日(ri)(ri)照市拔地(di)而起。27日(ri)(ri)下午，“牢記總書記囑(zhu)托奮力走(zou)在前列”——重(zhong)大(da)工程建設巡(xun)禮媒體采(cai)訪(fang)活動日(ri)(ri)照首站，走(zou)進日(ri)(ri)照鋼鐵(tie)精(jing)品(pin)基(ji)地(di)。據悉(xi)，日(ri)(ri)照鋼鐵(tie)精(jing)品(pin)基(ji)地(di)項目環(huan)保投(tou)資達(da)到64.7億元，投(tou)資項目涵蓋廢(fei)氣治(zhi)理(li)(li)(li)、廢(fei)水(shui)治(zhi)理(li)(li)(li)、噪聲治(zhi)理(li)(li)(li)、固廢(fei)處(chu)理(li)(li)(li)、余熱利用、環(huan)境綠化等內容。環(huan)保執行最嚴“標(biao)準(zhun)”，整個廠區廢(fei)水(shui)循(xun)環(huan)利用，向“零”排放目標(biao)邁進。  

環保執行最嚴“標準”排放指標居世界領先水平  

日(ri)照是聯(lian)合國公布的宜居城市(shi)，日(ri)照鋼鐵(tie)精品(pin)基地秉承(cheng)山鋼“低碳清潔，綠色(se)山鋼”的環(huan)保(bao)理念，項目建設投產(chan)后，排放指標可達到2020年排放濃(nong)度限值要求(qiu)，污染物(wu)排放指標居世界領先水平。  

記者(zhe)了解到(dao)，日照(zhao)鋼鐵精品(pin)基(ji)地(di)項(xiang)(xiang)目(mu)(mu)環保(bao)投資(zi)達到(dao)64.7億元(yuan)，投資(zi)項(xiang)(xiang)目(mu)(mu)涵(han)蓋廢(fei)氣治理(li)、廢(fei)水治理(li)、噪(zao)聲治理(li)、固(gu)廢(fei)處理(li)、余熱利用、環境綠化(hua)、環境監(jian)測及生態(tai)修復等內(nei)容。與近(jin)年來國內(nei)其他鋼廠的(de)環保(bao)投資(zi)相比，日照(zhao)鋼鐵精品(pin)基(ji)地(di)工程是目(mu)(mu)前國內(nei)環保(bao)投資(zi)及比例最高的(de)鋼鐵項(xiang)(xiang)目(mu)(mu)。  

技術創新節能減排---崛起別樣鋼廠  

“創新(xin)采(cai)用(yong)管理節能(neng)(neng)、工藝節能(neng)(neng)、技術(shu)節能(neng)(neng)三位一體節能(neng)(neng)設計(ji)模式(shi),與國內先進企業相比，節能(neng)(neng)7%以(yi)上，年(nian)節能(neng)(neng)量30萬噸標(biao)煤以(yi)上，年(nian)減排(pai)二氧化(hua)碳78萬噸以(yi)上。”日照公司能(neng)(neng)源環保(bao)中心負責(ze)節能(neng)(neng)減排(pai)的陳力軍滿(man)懷信心地說(shuo)。  

日照鋼(gang)鐵精品基地在能(neng)(neng)(neng)源管(guan)(guan)(guan)理(li)設(she)計方面，采(cai)(cai)用(yong)了(le)能(neng)(neng)(neng)源管(guan)(guan)(guan)理(li)體系和智能(neng)(neng)(neng)管(guan)(guan)(guan)控(kong)(kong)中(zhong)心“動”、“靜”結(jie)(jie)(jie)合(he)，“管(guan)(guan)(guan)理(li)、控(kong)(kong)制(zhi)、操(cao)作”縱橫一(yi)體，“工業化(hua)(hua)、信(xin)息化(hua)(hua)、智能(neng)(neng)(neng)化(hua)(hua)”多化(hua)(hua)融合(he)的管(guan)(guan)(guan)控(kong)(kong)模式，確(que)保能(neng)(neng)(neng)源動態管(guan)(guan)(guan)控(kong)(kong)和高(gao)(gao)效(xiao)利用(yong)。在工藝(yi)(yi)裝備設(she)計方面，采(cai)(cai)用(yong)5100m3高(gao)(gao)爐、500m2燒結(jie)(jie)(jie)機、7.2m焦爐、210t轉(zhuan)爐、2050mm熱軋、2030mm冷軋等(deng)國(guo)際領先水(shui)平的大型化(hua)(hua)、智能(neng)(neng)(neng)化(hua)(hua)、科學化(hua)(hua)工藝(yi)(yi)裝備，全部達到并超過國(guo)家產業政(zheng)策的要求，奠定(ding)了(le)節能(neng)(neng)(neng)的基礎。在工藝(yi)(yi)技術設(she)計方面，采(cai)(cai)用(yong)了(le)高(gao)(gao)風溫(wen)富氧大噴煤(mei)、小(xiao)球低溫(wen)厚料(liao)層(ceng)燒結(jie)(jie)(jie)、“負(fu)能(neng)(neng)(neng)”煉鋼(gang)、煤(mei)氣凈(jing)化(hua)(hua)負(fu)壓(ya)等(deng)30余項(xiang)節能(neng)(neng)(neng)環保工藝(yi)(yi)技術,整體上(shang)處于國(guo)際領先水(shui)平。
