【摘要】：我國的水資源短缺形勢嚴(yán)峻,深度挖掘非傳統(tǒng)水資源,緩解我國經(jīng)濟(jì)發(fā)展與水資源短缺之間的矛盾,是保障我國可持續(xù)發(fā)展的必由之路。城市污水處理及資源化是更為穩(wěn)定且廣泛適用的非傳統(tǒng)水源開發(fā)利用方式,但城市集中再生水處理面臨著高昂的輸送成本和回用管網(wǎng)敷設(shè)困難等諸多問題,相對(duì)而言分散式再生水處理技術(shù)有其顯著的優(yōu)越性,正逐漸獲得更多的關(guān)注。著重介紹了3種城鎮(zhèn)分散式低碳生態(tài)污水處理工藝,從處理效果、能耗水平、適用規(guī)模和占地面積等方面,對(duì)相關(guān)國內(nèi)外工程案例的運(yùn)行數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析,研究認(rèn)為這3種基于生態(tài)工程原理的污水處理新工藝具有結(jié)構(gòu)緊湊占地面積小、能耗水平低、出水水質(zhì)穩(wěn)定、設(shè)施造型美觀適用范圍廣等較多優(yōu)勢,值得我國進(jìn)行研究和引進(jìn)消化。
[Abstract]:The situation of water resources shortage in our country is severe. It is the only way to guarantee the sustainable development of our country to dig into non-traditional water resources in depth and to alleviate the contradiction between economic development and water resources shortage in our country. Urban sewage treatment and reuse is a more stable and widely applicable way of developing and utilizing unconventional water sources. However, urban centralized reclaimed water treatment is faced with many problems, such as high transportation cost and difficulties in laying reuse pipe networks, etc. Relatively speaking, dispersive reclaimed water treatment technology has its obvious advantages and is gradually gaining more attention. In this paper, three kinds of decentralized low carbon ecological wastewater treatment processes in cities and towns are introduced. The operation data of relevant domestic and foreign engineering cases are analyzed statistically from the aspects of treatment effect, energy consumption level, applicable scale and occupation area, etc. It is considered that these three new wastewater treatment processes based on ecological engineering principle have many advantages, such as compact structure, small area, low energy consumption, stable effluent quality, wide application range of beautiful appearance of facilities, and so on. It is worth our country to carry on the research and the introduction digestion.
