摘要
为了降低水体富营养化,以造纸白泥作为除磷剂,考察了初始溶液浓度、时间、温度、pH和白泥投加量五种因素对磷去除率的影响。结果表明,白泥是一种有效的除磷剂,初始溶液浓度越高,白泥对磷的去除量越大;在温度为25℃,白泥用量每100mL为8g,pH为8-10的实验条件下,磷的去除率可达75%以上。
To lower the trend of serious eutrophication of reservoirs, this paper studied the ability of white mud to remove phosphorus from wastewater. The effect of temperature, reaction time, pH, initial phosphorus concentration and quantity on the phosphorus removal by white mud was investigated. The results showed that white mud is effective to removal phosphorus, the higher the greater the removal capacity of white mud to phosphorus; when the water temperature was 25℃, amount of white mud used 8 g, under pH 8 - 10 condition, the efficiency of phosphorus removal rate reached about 75 %.
