摘要
厌氧酸化作为铁屑过滤的预处理,可降低废水pH,改变染料性质,去除部分色度和COD,为铁屑过滤创造了条件。色度和COD去除率分别达到91%和82%以上,出水符合国家一级排放标准(GB8978—88)。
Anaerobic acidulate,as pre-treatment for iron chip filter,could remove color and COD partly;The value of PH of wastewater dropped and dyeing properties were changed,hence the efficiency of ironchip filter could be improved to 91 % and 82% for color and COD removal respectivelyThe effluent couldmeet the first standard of GB8978-88.
