【摘要】 作者采用酸析结合铁碳内电解法对苎麻废水进行了预处理,探讨了pH调节条件及铁碳内电解法对废水处理效果的影响。结果表明,在室温下将废水pH调节至3.00时,COD cr可以从15789.47m g/L下降到11491.23m g/L,COD cr去除率达27.22%,色度去除率达83.58%;接着在pH=3.00,处理时间40m in,铁碳加入量:废水(质量比)=1:5,铁:碳=3:1,温度=300C的最佳工艺条件下,用铁碳内电解法进一步对废水进行了处理,COD cr可以进一步下降到6948.38m g/L,COD cr去除率接近55%,色度去除率达80%。更多还原

【Abstract】 Ramie wastewater was pretreated by acidification combined with icon chip inner-electrolysis in this paper.We discussed how pH adjustment and iron chip inner-electrolysis effect on the treatment of waste water.When the pH of wastewater was adjusted to 3.0 at room temperature,some organic matter would be removed from the water.As a consequence,CODcr and color rate would have a decrease in 83.58% and 27.22%,respectively.Then,under the most favorable working condition,we futher treated the wastewater by the above method,resulting in the removal rate of colors and CODcr reaching about 80% and 55%,repectively.The condition is as follows: pH=3.00,reaction time=40 min,mass ratio of Fe&C to wastewater=0.2,Fe:C=3,and the temperature=30℃.更多还原
