【摘要】 集约化养猪场排出大量污水对外界环境所造成的污染已广泛引起人们关注.本文采用漂白Ⅱ号溶液(Chlorine Water Ⅱ)对猪场污水怍脱色与脱臭及去除 COD 的探讨.试验结果表明:漂泊Ⅱ号溶液对污水脱色,脱臭及降解 COD 的效果均比较理想.漂白Ⅱ号溶液用量为1%时,可除臭65%,降低 COD50%,并把原来污水由黑色变为淡黄色;漂白Ⅱ号溶液用量为2%时,可除臭90%,降低 COD 量65%,并把原来污水由黑色变为黄色.更多还原

【Abstract】 With Chlorine Water Ⅱ,the decolouration,deodorization and elimination COD of the sewage from piggery were studied in this paper.The results indicated that Chlorine Water Ⅱ was applied to them well.The sewage was de- odorized to achieve the effective rate of sixty—five and seventy—five percent,COD of the sewage was removed to achieve the effective rate of fifty and sixty-five percent,and the sewage got light yellow and yellow from the black,respectively while Chlorine Water Ⅱ was used with the concentration of one and two percent.更多还原
