摘要
广东省某农村黑臭水体,成因复杂,位于河网密集区域,一直面临着严重污染。具有建筑分布不规律,排口分散,管道接驳难度高;沿河用地紧张,施工难度高等特点。从四个层面、全流程逐级建立黑臭水体治理系统框架,保证水质长久达标。首先对现状问题调研,定量分析成因;接着制定完整的工程体系;随后以不同典型地层为研究对象采取分段施工,优化具体实施技术方案,对不同施工工艺进行适用范围比选;最后通过微生物测序技术分期评估实施效果,进一步调整技术方案,研究表明工程子项的实施时序及处理好河涌上下游关系对避免河涌底泥淤积和水质变差具有重要意义。
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.Subsequently,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.
