水中的高锰酸盐指数评价数据

水中高锰酸盐指数监测是测定水污染的一种方法手段，通过检测水中高锰酸盐的指数方可检测出水域的污染浓度，经过采样、实验及计算方式可分析出水域的情况。在通过对水质中的高猛酸盐指数的测定，对结果进行科学性的分析，保证监测系数的准确性，为政府监管、居民生活以及生态环境提供参考和技术支撑。通过对各送检水内高锰酸钾指数的检测，依据高锰酸盐指数的测定国家标准GB/T11892-198，取样加入高锰酸钾溶液，在酸式滴定管记录样品滴定高锰酸钾溶液滴定消耗量V1（mL），标定时所消耗高锰酸钾溶液体积V2（mL），根据标准确定M的标准数值进行计算，得出水质中高锰酸盐指数的数据，公式如下：高锰酸盐指数C（mg/L）={【（10+V1）+10/V2）-10】*M*8*1000}/100。通过国家分类标准GB 3838-2002表得出最后的结论判断，III是三类水，含量≤6mg/L，IV是四类水，含量6-10mg/L，V是五类水，含量10-15mg/L，超过V的标准值（＞15mg/L）就是劣五类水则是不合格，需要相关监管部门监管并治理。

Monitoring of permanganate index is a standard method for water pollution determination. The pollution concentration of a water body can be detected by measuring its permanganate index, and the water quality status can be analyzed via sampling, laboratory experiments and calculation procedures. By measuring the permanganate index in water samples and performing scientific analysis on the test results, the accuracy of monitoring data can be guaranteed, providing reference and technical support for government environmental supervision, residents' daily lives and ecological environment protection.
For the detection of permanganate index in various submitted water samples, follow the national standard GB/T11892-198 for permanganate index determination: take samples and add potassium permanganate solution, record the titration consumption volume V1 (mL) of potassium permanganate solution for sample titration using an acid burette, as well as the volume V2 (mL) of potassium permanganate solution consumed during standard calibration. Calculate the permanganate index data of the water sample using the standard value of M specified in the standard. The calculation formula is as follows:
Permanganate index C (mg/L) = {[(10 + V1) + 10/V2] - 10} × M × 8 × 1000 / 100
Based on the classification table specified in National Standard GB 3838-2002, the final water quality judgment can be made: Class III water has a permanganate index ≤6 mg/L, Class IV water has an index of 6-10 mg/L, Class V water has an index of 10-15 mg/L, and water with an index exceeding 15 mg/L is classified as inferior Class V water, which is deemed unqualified and requires supervision and treatment by relevant regulatory departments.
