基于水污染指数法的涡河(蒙城段)水质评价分析

Evaluation and Analysis of Water Quality of Guohe(Mengcheng Section)Based on Water Pollution Index Method

水质监测与评价对保护水环境健康与可持续发展至关重要。基于涡河蒙城段岳坊站、双涧站2016-2021年水质检测指标数据,通过水污染指数法,选取化学需氧量CODcr、溶解氧DO、氨氮NH3-N、高锰酸盐CODMn作为水质评价的主要指标。结果表明,近年涡河蒙城段水质逐步改善,但水质仍一般,处于Ⅲ~Ⅳ类动态变化。研究结果可为下一步沿河管理、污染源控制提供科学依据。

Water quality monitoring and evaluation are crucial to the protection of water environment health and sustainable development.Based on the water quality testing index data of Yuefang and Shuangjian in Mengcheng of the Guohe from 2016 to 2021,through the water pollution index method,CODcr,DO,NH3-N and CODMn were selected as the main indicators for water quality evaluation.The water quality has been gradually improved,but the water quality is still average,and is in the dynamic change of ClassⅢto ClassⅣ.The research results provide a scientific basis for the next step of riverside management and pollution source control.
