摘要：火電廠廢水零排放技術(shù)，屬當(dāng)前電力工業(yè)重點發(fā)展
研究的關(guān)鍵技術(shù)之一。分級濃縮串聯(lián)補水技術(shù)， 將電廠循
環(huán)水分成兩級進行處理，補給水串聯(lián)運行。即第1級原水
經(jīng)工業(yè)水系統(tǒng)使用后進入第1級機組循環(huán)水系統(tǒng)低濃縮倍
率運行，第1級循環(huán)排污水經(jīng)過濾、弱酸離子交換樹脂脫
堿軟化處理后作為第2級機組循環(huán)補給水，第2級機組的
循環(huán)水系統(tǒng)采用高濃縮倍率運行，其排污水經(jīng)澄清過濾和
反滲透處理后作為鍋爐補給水處理系統(tǒng)原水和循環(huán)水系統(tǒng)
補給水。西柏坡電廠采用該技術(shù)在全國火力發(fā)電廠率先實
現(xiàn)廢水零排放，取得了較好的經(jīng)濟、社會和環(huán)保效益。

關(guān)鍵詞：廢水零排放；分級濃縮；串聯(lián)補水

ABSTRACT: The zero discharge technique of the
wastewater in thermal power plants is one of the key techniques to be developed and studied in power industry at present. Our technique of concentrating serial make-up water in stages has filled adomestic gap with a breaking progress.
The thermal power plants have realized the zero discharge for the wastewater in priority. The paper introduces the technical principles, features, applicable conditions, effect and economical benefits of this technique.

KEYWORDS: Zero discharge for the wastewater；
Concentration in stages；Serial make-up water
