【摘要】 中小河流的河道演变较为缓慢，而且与农业、工业以及人们的日常生活有着密切关系，它在功能上具有一定的多样性，包括蓄水灌溉、饮用水源、渔业养殖等。从中小河流域的特点来看，它受外界环境影响严重。在时代的发展进程中，工业废水、农业污水的不规范排放可能会对中小河流域水环境造成不同的污染，需要通过修复和治理技术的应用避免富营养化等现象的发生，确保水环境生态系统的合理性。本文通过阐述中小河流域水环境污染的主要原因，分析了中小河流域水环境治理的主要技术，并且就中小河流域水环境治理中存在的问题进行了说明，从而探讨了加强中小河流域水环境治理的措施。更多还原

【Abstract】 The river course evolution of small and medium-sized rivers is relatively slow,and has a close relationship with agriculture,industry and daily life.It has a certain diversity in functions,including water storage irrigation,drinking water sources,fishery and aquaculture.From the perspective of the characteristics of the small and medium-sized river basin,it is seriously affected by the external environment.In the development process of the times,the irregular discharge of industrial wastewater and agricultural wastewater may cause different pollution problems to the water environment of the river basin.It is necessary to avoid the occurrence of eutrophication and other phenomena through the application of remediation and governance technologies to ensure the rationality of the water environment ecosystem.This article expounds the main causes of water environment pollution in small and medium-sized river basins,analyzes the main technologies for water environment treatment in small and medium-sized river basins,and explains the problems in water environment treatment in small and medium-sized river basins,so as to discuss measures to strengthen water environment treatment in small and medium-sized river basins.更多还原
