The Application Of Ecological Restoration In The Treatment Of Black And Smelly Water Body

In recent years,the problem of black and odorous water caused by the indiscriminate pollution of urban pollution and the mess of sewage pipes left over from history has become increasingly serious.The extremely sensory experience of urban black and odorous water bodies and the desire of healthy and beautiful life that urban residents desire The contradiction has also become increasingly sharp,and the governance of urban black and odorous water has received extensive attention from the national government and the people.Wearing the Chuanzi River is a city in the city of Changde.However,with the continuous expansion of the city,a large amount of domestic garbage and industrial waste water slag are randomly discharged,making it a serious pollution,stinking ditch,serious It has affected the living environment of residents and the urban style of Changde City.With the advancement of ecological civilization construction,the transformation of the Chuanzi River is imminent.Ecological restoration technology is one of the most green economy in many environmental treatment technologies.This study takes the reconstruction of the Chuanzi River as an example,and uses ecological restoration to control the urban black and odorous water body,and examines the actual restoration of ecological restoration technology in engineering applications.The effect is to provide engineering experience and practical basis for ecological restoration in the application of black odor water treatment.Through the preliminary survey and investigation,this study has mastered the pollution situation of the river waters,and adopted riverbed dredging and other riverbed reforms to start from the pollution source,standardize the pollutant discharge,and perform aeration and reoxygenation into the water body of the Chuanzi River.The means of ecological restoration,protection of the river course,setting up an ecological floating bed to improve the purification effect of the river water body,upgrading the river channel of the Chuanmatou to the Baima Lake section,starting from the source of pollution,and ecological restoration of the river Fundamentally eliminate urban black and odorous water bodies.After the river channel reconstruction,the amount of sewage reduction was 56.563t/a.The water monitoring data after the restoration showed that the annual over-standard rate of COD decreased by 94.4%,the ammonia nitrogen concentration decreased by 65%,the annual excess rate of total phosphorus decreased by 94.4%,and the dissolved oxygen content increased.370%,affected by seasonal temperature,the summer water body repair effect is the best time of the year.Due to the temperature drop in autumn and winter,the biological activity is affected,and the water body repair effect is not good,but it is also better than the water quality before the restoration.The Chuanzi River ecological restoration project has low operating cost,stable treatment effect,clean water surface in the treatment area,no floating matter such as algae garbage,normal color of water body,basically eliminate black odor,beautify the urban landscape,and grow well in floating plants and emergent plants.The river water quality has reached the expected requirements,and the river ecology has become a benign recovery.The project of upgrading the purple river water quality will promote the construction of local infrastructure and cultural services,improve the material living standards of the people,enrich their spiritual and cultural life,and increase their sense of security and quality of life.
