海绵铁处理酱油废水实验研究

Study of the Treatment of Sauce Wastewater by Sponge Iron

采用静态实验对海绵铁处理酱油废水进行了研究,从海绵铁粒径、投加量、废水pH值和反应时间四个方面研究了对处理效果的影响。结果表明,海绵铁处理酱油废水的最适条件：在原水COD浓度2 500 mg.L-1、反应时间60 min、中性或弱酸性环境、海绵铁投加量20 g、粒径0.5-1.0 mm情况下,海绵铁对废水COD、色度的去除率分别达到了35.3%和49.6%。

Sauce wastewater is typically the high concentration in COD concentration and color.Process parameters to remove pollution in sauce wastewater were researched by using static experiments.Static test is conducted in sponge iron particle size,the amount of sponge iron,pH and reaction time.The best treatment conditions is： COD density is 2500 mg·L-1,the reaction time 60 minutes,the liquid condition is neutral or faintly acid,the adding quantity of sponge iron 20 grams and the grain diameter 0.5~1.0 mm.Under this condition,the removal rate of COD and color is 35.3% and 49.6% respectively.
