摘要
研究了无烟煤－石英砂滤料接触氧化法除工业冷却水中锰、铁的工艺条件。滤料粒径０５ｍｍ～１０ｍｍ，滤床高８００ｍｍ（无烟煤、石英砂滤料各４００ｍｍ），滤速１０ｍ／ｈ～１２ｍ／ｈ，工作周期９６ｈ，反冲洗强度１０Ｌ／（ｍ２·ｓ），反冲洗时间５ｍｉｎ～７ｍｉｎ，出水Ｍｎ２＋浓度为００４ｍｇ／Ｌ以下，去除率可达９０％以上，总铁浓度为痕量。
Abstract This paper focuses on the research of a process to remove manganese and iron from the industrial cooling water by contact oxidation process using natural filtering media of anthracite and quartzite. The operating parameters are: size of filTering maTerial 0.5 to 1.0 mm, filtering bed height 800mm, filtering speed 10 to 12 m/h, working cycle 96 hours, backwashing strength 13 L/(m 2·s) and backwashing time 5 to 7 min. In the treated water the residual Mn 2+ concentration is below 0.04mg/L with removal ratio up to 90% and the total Fe is trace level.
