ABSTRACT

The Water Environment Monitoring Center of Shiyan City is responsible for monitoring the water quality within the area month by month. The Nemerow Pollution Index (IP) is chosen to analyze the water quality status from 2015 to 2017 by selecting important reservoir-type water sources. The evaluation of reservoir eutrophication is based on the Technical Regulation of Surface Water Quality Evaluation (SL395-2007). Results show that the water quality of the water source is relatively good, but the occasional problem of large total nitrogen in the total phosphorus cannot be ignored.

1. 引言

2. 水源地水质分析

2.1. 内梅罗水污染指数法简介

${I}_{p}=\sqrt{\frac{{\left({I}_{max}^{i}\right)}^{2}+{\left(\overline{I}\right)}^{2}}{2}}$

$\overline{I}=\frac{1}{n}{\sum }_{i=1}^{n}{I}_{i}$ , ${I}_{i}=\frac{{C}_{i}}{{C}_{oi}}$

1) 当 ${I}_{p}$ 小于等于1.5的时候，表示水体是清洁的。

2) 当 ${I}_{p}$ 值大于1.5小于3.0的时候，表示水体是轻度污染。

3) 当水体 ${I}_{p}$ 值大于3.0时的时候，表示水质受到污染的。

4. 结论

1) 用2015年至2017年3年逐月翔实的资料，评价出十堰市水库型饮用水水源地水质是清洁的，根据水功能区达标评价办法，达标率大于80%的功能区为达标功能区，水源地水质全部达标，但也出现轻度污染现象。

2) 丹江口水库、丹江口水库(郧县)、黄龙滩水库、白岩河水库连续三年全部为中营养，竹溪河水库2015出现6次轻度富营养，年均值为轻度富营养；2016年出现2次轻度富营养，年均值为中营养；2017年出现4次轻度富营养，年均值为中营养。

3) 十堰市饮用水水源地水质是好的，但总氮、总磷偏大问题不容忽视。
