Study on Treatment Technology of Black and Odorous Water Body
With the rapid progress of urbanization,although people's living environment has been greatly im-proved,it is also inevitable that the supporting infrastructure of cities cannot keep up with the urbanization pro-cess in a timely manner,resulting in some negative impacts on the natural environment.The acceleration of the urbanization process has promoted the rapid growth of population and the rapid development of industry,but there are relatively few infrastructure related to sewage and wastewater discharge and treatment,therefore,increasing sewage and wastewater are discharged into urban water bodies,resulting in the emergence of black and smelly water bodies,which seriously affects the life experience of residents and the appearance of the city,therefore,it is urgent to comprehensively regulate urban black and smelly water bodies.In this paper,using the existing equip-ment and technology in the field of sewage treatment of a group,combined with relevant cases,the conventional treatment and restoration technology of black and smelly water was briefly analyzed.The results show that the technical routes of"external blocking,internal desilting,water purification,clean water supply and ecological restoration"can effectively alleviate the appearance of black and odorous water bodies and improve water quality.
