遠水(shui)難解近(jin)渴,水(shui)資源化近(jin)道鎖定再生水(shui)利用(yong)!

       2022年8月8日,四(si)川(chuan)省人民(min)政府公布關(guan)于(yu)成(cheng)都市(shi)(shi)(shi)(shi)、自貢市(shi)(shi)(shi)(shi)、遂寧市(shi)(shi)(shi)(shi)、內江市(shi)(shi)(shi)(shi) 、資陽(yang)市(shi)(shi)(shi)(shi)5個(ge)典(dian)型地(di)區再生水利(li)用配置試點城市(shi)(shi)(shi)(shi)實施方案的批復。文件顯(xian)示,到(dao)2025年,力(li)爭這5市(shi)(shi)(shi)(shi)的再生水利(li)用率(lv)達到(dao)35%以上,實現(xian)水資源循環(huan)高(gao)效利(li)用。
 
  先前(qian),國(guo)家6部門聯合(he)發布(bu)《典(dian)(dian)(dian)型(xing)地(di)(di)區(qu)再生(sheng)(sheng)水(shui)利用(yong)配置(zhi)試(shi)點(dian)方案》,明確將(jiang)以(yi)缺(que)水(shui)地(di)(di)區(qu)、水(shui)環境(jing)敏感(gan)地(di)(di)區(qu)、水(shui)生(sheng)(sheng)態脆弱地(di)(di)區(qu)為重(zhong)點(dian),選擇(ze)典(dian)(dian)(dian)型(xing)代表性強、再生(sheng)(sheng)水(shui)利用(yong)配置(zhi)基礎好(hao)、再生(sheng)(sheng)水(shui)需求量大的縣級(ji)及以(yi)上城市(shi)開展試(shi)點(dian)。“十四五”期(qi)間,缺(que)水(shui)地(di)(di)區(qu)試(shi)點(dian)城市(shi)再生(sheng)(sheng)水(shui)利用(yong)率達到(dao)35%以(yi)上,京津冀地(di)(di)區(qu)試(shi)點(dian)城市(shi)達到(dao)45%以(yi)上,其他地(di)(di)區(qu)試(shi)點(dian)城市(shi)達到(dao)25%以(yi)上。最(zui)終(zhong)于2025年,在再生(sheng)(sheng)水(shui)規劃、配置(zhi)、利用(yong)、產(chan)輸(shu)、激勵等方面(mian)形(xing)成(cheng)一批(pi)效(xiao)果好(hao)、能持續、可推廣的先進模(mo)式和典(dian)(dian)(dian)型(xing)案例。
 
  國(guo)家大力推進(jin)再生水循環利(li)用,污水也(ye)獲得(de)了重(zhong)復利(li)用的(de)可能性。

  目前,再(zai)(zai)生(sheng)水(shui)(shui)利(li)用(yong)(yong)(yong)最為(wei)廣泛(fan)的領域當屬城市(shi)用(yong)(yong)(yong)水(shui)(shui)。城市(shi)用(yong)(yong)(yong)水(shui)(shui)中,再(zai)(zai)生(sheng)水(shui)(shui)已經(jing)被主要用(yong)(yong)(yong)于河道(dao)生(sheng)態補水(shui)(shui)、工(gong)業供水(shui)(shui)和(he)市(shi)政雜用(yong)(yong)(yong)用(yong)(yong)(yong)水(shui)(shui)。被列(lie)入(ru)全(quan)國首批典型(xing)地(di)區再(zai)(zai)生(sheng)水(shui)(shui)利(li)用(yong)(yong)(yong)配(pei)置(zhi)試(shi)點城市(shi)名(ming)單的寧波(bo),也已定下階段性(xing)目標(biao),2025年,再(zai)(zai)生(sheng)水(shui)(shui)利(li)用(yong)(yong)(yong)率要達到35%,再(zai)(zai)生(sheng)水(shui)(shui)利(li)用(yong)(yong)(yong)量70萬噸/日。
 
  在列入試點后,寧(ning)波(bo)擴(kuo)大(da)再(zai)生(sheng)水(shui)(shui)(shui)利用(yong)(yong)面,增(zeng)大(da)再(zai)生(sheng)水(shui)(shui)(shui)利用(yong)(yong)量的任務目(mu)標提(ti)升(sheng)(sheng)。寧(ning)波(bo)還將(jiang)如何發力(li)(li)?環保在線了解(jie)到(dao),寧(ning)波(bo)將(jiang)在“十四五(wu)”期間重點實施五(wu)大(da)工程(cheng)(cheng),包括加強污水(shui)(shui)(shui)收集及再(zai)生(sheng)水(shui)(shui)(shui)能(neng)力(li)(li)提(ti)升(sheng)(sheng)工程(cheng)(cheng)等,增(zeng)污水(shui)(shui)(shui)收集管網(wang)、增(zeng)污水(shui)(shui)(shui)處理能(neng)力(li)(li)、增(zeng)再(zai)生(sheng)水(shui)(shui)(shui)輸送管道,最(zui)終形成“一(yi)環兩片多點”的再(zai)生(sheng)水(shui)(shui)(shui)利用(yong)(yong)布局,為再(zai)生(sheng)水(shui)(shui)(shui)利用(yong)(yong)率提(ti)升(sheng)(sheng)服務。
 
  再生水(shui)為(wei)城市(shi)“解渴”,緩解著用水(shui)緊張(zhang)問題。

  今年5月末,寧夏(xia)蘇銀產(chan)業園再生水(shui)(shui)(shui)(shui)廠(chang)正(zheng)式通水(shui)(shui)(shui)(shui)運行(xing),據說實現了“污(wu)(wu)水(shui)(shui)(shui)(shui)100%截(jie)流(liu)(liu)、中水(shui)(shui)(shui)(shui)100%回用(yong)”的目標(biao),6月底,蘇州(zhou)市(shi)區的首(shou)個再生水(shui)(shui)(shui)(shui)利(li)用(yong)項(xiang)目——“綠(lv)色·未來”污(wu)(wu)水(shui)(shui)(shui)(shui)資源化(hua)利(li)用(yong)項(xiang)目也正(zheng)式簽(qian)約(yue),年供(gong)水(shui)(shui)(shui)(shui)量設計(ji)在200-250萬噸,將有效(xiao)節(jie)約(yue)城市(shi)水(shui)(shui)(shui)(shui)資源,緩解(jie)用(yong)水(shui)(shui)(shui)(shui)壓力。最近(jin) ,湖北省(sheng)當陽(yang)市(shi)再生水(shui)(shui)(shui)(shui)循環利(li)用(yong)及水(shui)(shui)(shui)(shui)環境生態(tai)治理工程設計(ji)采購施工總(zong)承包(EPC)項(xiang)目也開始了招標(biao)工作,將對沮(ju)漳河流(liu)(liu)域(yu)的兩座(zuo)污(wu)(wu)水(shui)(shui)(shui)(shui)處理廠(chang)污(wu)(wu)水(shui)(shui)(shui)(shui)進行(xing)再生利(li)用(yong)并改善(shan)區域(yu)水(shui)(shui)(shui)(shui)環境……
 
  再生水利用(yong)系統建設(she)在(zai)各(ge)地(di)(di)鋪設(she)開去,綜合來看,推動再生水利用(yong)是水資源化的必經之路,也是充分契合社會(hui)發(fa)(fa)展需要(yao)的重要(yao)舉措。期待各(ge)城市在(zai)再生水利用(yong)試點的過程中(zhong),為地(di)(di)區再生水循環利用(yong)提(ti)供更多(duo)可(ke)行的發(fa)(fa)展模式。
