We know that water has no color and no taste, so many people think that they can tell whether the water is polluted with the naked eye. That’s not true! There are a lot of bacteria and heavy metals in the water, which are invisible to the naked eye. So how can we tell if the water is polluted? The following water quality online monitoring instrument manufacturers to understand together with you! There are several ways!
1.Water environment background investigation: It refers to the determination of the original chemical composition of the water body in the natural development process without being affected by man-made pollution. At present, it is difficult to find water bodies that are not affected by pollution, so the background of understanding water environment is actually a relative value, which can be used as a reference index to judge the degree of water bodies affected by pollution.
2.Pollution source investigation: Pollution source is an important factor affecting water quality. Through pollution source investigation and evaluation, the main pollutants in the water body can be determined, so as to determine the water quality testing and evaluation items;
3.Water quality monitoring: According to water quality investigation and pollution source evaluation, combined with water quality use, develop the corresponding monitoring program, can entrust a third-party monitoring organization for sampling analysis, to obtain water quality monitoring data necessary for water quality evaluation;
4.Determine the evaluation standards: water quality standards are the criteria and basis for water quality evaluation. For the same water body, different standards will result in different evaluation results, such as industrial water and drinking water, their standards are different, so the evaluation results are different. Therefore, the evaluation criteria should be selected according to the use and purpose of the evaluated water body.
Judging water pollution requires some professional knowledge, as for what method you want to use to judge whether the water quality is polluted, it depends on its own situation to decide!
