Technical Analysis of Treatment Methods of Black-odorous Waterbodies
Analyze the formation mechanism of black and odorous water bodies,focusing on the key factors that lead to water blackening and the production of foul odors,as well as the microbial species that play a dominant role in this process.Evaluate the effectiveness of common treatment methods,including artificial aeration,sediment dredging,microbial enhancement techniques,and artificial wetlands,under different environmental conditions.The research results show that metal sulfides and volatile organic sulfur compounds are the main chemical components causing black and odorous water bodies;Sulfate reducing bacteria,Bacteroidetes,and Proteobacteria play a core role in the formation of black and odorous water bodies;Under different environmental conditions,the above-mentioned treatment technologies exhibit varying effects,among which microbial enhancement technology and artificial wetlands show higher treatment efficiency under specific conditions.When implementing the treatment of black and odorous water bodies,the mechanism and applicable conditions of the methods should be fully considered,and the treatment strategies should be reasonably selected and optimized.At the same time,it is emphasized that comprehensive measures should be taken,not only to solve the current pollution problems,but also to pay more attention to the long-term health and restoration of the water ecosystem,in order to achieve sustainable water management and environmental protection goals.
