摘要：火電廠(chǎng)廢水零排放技術(shù)，屬當(dāng)前電力工業(yè)重點(diǎn)發(fā)展
研究的關(guān)鍵技術(shù)之一。分級(jí)濃縮串聯(lián)補(bǔ)水技術(shù)， 將電廠(chǎng)循
環(huán)水分成兩級(jí)進(jìn)行處理，補(bǔ)給水串聯(lián)運(yùn)行。即第1級(jí)原水
經(jīng)工業(yè)水系統(tǒng)使用后進(jìn)入第1級(jí)機(jī)組循環(huán)水系統(tǒng)低濃縮倍
率運(yùn)行，第1級(jí)循環(huán)排污水經(jīng)過(guò)濾、弱酸離子交換樹(shù)脂脫
堿軟化處理后作為第2級(jí)機(jī)組循環(huán)補(bǔ)給水，第2級(jí)機(jī)組的
循環(huán)水系統(tǒng)采用高濃縮倍率運(yùn)行，其排污水經(jīng)澄清過(guò)濾和
反滲透處理后作為鍋爐補(bǔ)給水處理系統(tǒng)原水和循環(huán)水系統(tǒng)
補(bǔ)給水。西柏坡電廠(chǎng)采用該技術(shù)在全國(guó)火力發(fā)電廠(chǎng)率先實(shí)
現(xiàn)廢水零排放，取得了較好的經(jīng)濟(jì)、社會(huì)和環(huán)保效益。

關(guān)鍵詞：廢水零排放；分級(jí)濃縮；串聯(lián)補(bǔ)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；
