摘要：火電廠廢水零排放技術，屬當前電力工業重點發展
研究的關鍵技術之一。分級濃縮串聯補水技術， 將電廠循
環水分成兩級進行處理，補給水串聯運行。即第1級原水
經工業水系統使用后進入第1級機組循環水系統低濃縮倍
率運行，第1級循環排污水經過濾、弱酸離子交換樹脂脫
堿軟化處理后作為第2級機組循環補給水，第2級機組的
循環水系統采用高濃縮倍率運行，其排污水經澄清過濾和
反滲透處理后作為鍋爐補給水處理系統原水和循環水系統
補給水。西柏坡電廠采用該技術在全國火力發電廠率先實
現廢水零排放，取得了較好的經濟、社會和環保效益。

關鍵詞：廢水零排放；分級濃縮；串聯補水

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；
