严寒地区城市河道底泥泥质分析及治理技术研究

Study on Argillaceous Analysis and Treatment Technology of Urban River Sediment in Severe Cold Area

以伊通河生态治理工程为背景,针对河道大量污染底泥造成的水体恶臭,生态环境恶劣等问题,采用现场调查、实验检测和现场实践相结合的方法,分析了底泥的主要成分、特征及形成因素,对河道底泥的治理方法进行了阐述和研究,综合考虑环保和底泥处理成本优化了环保清淤方案。并且,根据淤泥性质对其进行合理治理,彻底解决了内源污染问题,同时指出了河道底泥资源化处置的方向,环保效果良好,成本节约显著,具有一定的推广价值和借鉴作用。

Based on the ecological treatment project of Yitong River,aiming at the problems of malodorous water body and bad ecological environment caused by a large amount of polluted sediment,the main components,characteristics and formation factors of sediment are analyzed by combining field investigation,experimental detection and field practice.The treatment methods of river sediment are elaborated and studied,considering the cost of environmental protection and sediment treatment,the environmental dredging scheme is optimized.In addition,according to the nature of the sludge,reasonable treatment has been carried out,the problem of endogenous pollution has been completely solved.At the same time,the direction of river sediment resource disposal is pointed out,which has good environmental protection effect and significant cost saving.It will have certain popularizing value and reference function.
