Fenton试剂对富营养化湖水黑臭的氧化降解作用

通过室内实验,研究Fenton试剂对富营养化水体黑臭物质氧化降解作用。实验结果表明,在黑臭的富营养化水中投加Fenton试剂20 min后,水体臭味明显降低,90 min后水体臭味全部消除;水体浊度、色度有显著改善,水体浊度、色度去除率分别达73.73%和93.11%,显著高于对照组的53.4%和22%;水体溶解氧量显著提高;水体的pH值保持在7左右。鱼类毒理实验结果表明,最佳剂量的Fenton试剂对实验鱼类无急性毒性作用。

Effect of Fenton reagents on degradation of black-odor water in eutrophic water

The objective of this experiment was to evaluate the degradation effectiveness of water odor in eutrophic lake by Fenton’s oxidation.It is found that the water odor intensity was lessened by spraying Fenton reagent,of which reduction efficiency was achieved from obvious to 100% after 20 and 90 minutes reaction respectively.Water turbidity and color reduction rate were 73.7% and 93.11%,while for the counterpart treatment,53.4% and 22%,respectively.Additionally,the Fenton reagent had a significant effect on improving the dissolved oxygen content in the water and keeping the water’s pH at about 7.Fish toxicity test showed that Fenton reagent had no acute toxic effects on the tested fish.
