摘要
研究不同质量浓度的的葡萄糖、蔗糖和糖蜜3种碳源对水体中余氯的处理效果。结果表明:使用漂白粉的消毒水体在加入不同碳源后,水体中的余氯浓度都显著低于空白对照组(P<0.05),不同处理组间消除效果为:糖蜜组>葡萄糖组>蔗糖组,相同碳源组间浓度越大消除效果越显著(P<0.05);空白组余氯在24 h的衰减百分率为19%±0.1%,添加150 mg·L-1和100 mg·L-1的糖蜜8 h内均可完全去除余氯,只有150 mg·L-1的葡萄糖12 h内完全消除,蔗糖的效果最差,150 mg·L-1添加组24 h余氯衰减率为98%±0.1%;加入不同碳源后水质因子也发生了相应的变化。通过本实验的研究,在消毒水体中加入3种碳源中和余氯,既可以消除余氯,调节水体碳氮磷比例,也可以起到改良水质的作用。
The effects of three carbon sources of glucose, sucrose and molasses on the residual chlorine in water were studied. The results showed that the concentration of residual chlorine in the water was significantly lower than that in the blank control group after adding different carbon sources(P<0.05). The elimination effect between different treatment groups was: molasses group>glucose group>sucrose group;the greater the concentration between the same carbon source group, the more significant the elimination effect was significant( P<0.05);the percentage of residual chlorine in the blank group was 19% ±0.1% at 24 h, and the addition of 150 mg·L-1 and 100 mg·L-1 molasses for 8 h. The residual chlorine can be completely removed within the whole process. Only 150 mg·L-1 of glucose is completely eliminated within 12 h, and the effect of sucrose is the worst. The decay rate of residual chlorine in the 150 mg·L-1 addition group is 98%±0.1% after adding different carbon sources. Corresponding changes have also take n place during the water quality factor experiment.Through the research of this experiment, adding three kinds of carbon sources to neutralize residual chlorine in the disinfecting water body can eliminate the residual chlorine, adjust the proportion of carbon, nitrogen and phosphorus in the water body, and also can improve the water quality.
