Research and practice on multi level and full process rural black and odor water treatment system
A black and odorous water body in a rural area of Guangdong has a complex cause,located in a densely populated river network area,and has been facing serious pollution.Irregular distribution of buildings,scattered exhaust outlets,and high difficulty in pipeline connection;The land along the river is tight and the construction difficulty is high.Establish a framework for the management of black and odorous water bodies from four levels and throughout the entire process,ensuring long-term compliance with water quality standards.Firstly,conduct research on current issues and quantitatively analyze their causes.Next,develop a complete engineering system.Sub-sequently,segmented construction was taken as the research object for different typical strata,and specific implementation technical plans were optimized to compare and select the applicable scope of different construction processes.Finally,the implementation effect was evaluated by stages using microbial sequencing technology,and the technical plan was further adjusted.The study showed that the implementation timing of engineering sub items and the proper handling of the upstream and downstream relationships of rivers are of great significance in avoiding sediment deposition and water quality deterioration in rivers.
