| Abstract: | Black odor water body rebound is a big problem in the process of black odor water body management.In order to study how to completely eliminate black and smelly water and prevent it from rebounding,this experiment uses magnetic flocculation technology to remove pollutants and reduce water under the premise of in-situ treatment.Then,the water quality is continuously improved through the new carbon fiber ecological aquatic plants coupled with nano-aeration technology.The experimental results show that the improved sediment can effectively inhibit the release of pollutants from the sediment,and the magnetic flocculation technology has a significant effect on the reduction of pollutants in the black and odorous water.The removal rates of SS,COD,ammonia nitrogen and TP from black and odorous water are 71.8%,52.4%,20.5%and 66.2%respectively;Carbon fiber aquatic plants coupled with nano-aeration technology has the best effect in repairing black and odorous water.The water transparency increased from 15cm up to 48cm.The removal rates of COD,ammonia nitrogen and TP reach 88%,97%and 68.6%respectively,which can effectively improve the micro-ecological environment of water to form a virtuous circle,continuously improve the black odor water body and purify water quality. |
