Therefore, the evaluation of drinking water cannot simply apply the method of surface water evaluation.
A few scholars have proposed evaluation methods for drinking water quality, but there is a lack of thinking and discussion on the temporal and spatial distribution of pipe network water supply

[0067] 1. Classification of water quality evaluation factors
[0068] This example only uses the monthly inspection data of a water supply company in central Jiangsu. The inspection items are microbiological indicators (total coliform, residual chlorine, total number of colonies), sensory properties and general chemical indicators (turbidity, chroma, iron, manganese) and toxicological indicators (lead, mercury, nitrate)
[0069] 2. Single water quality factor evaluation and category evaluation
[0070] ⑴Evaluation of individual water quality factors
[0071] In order to illustrate the evaluation and calculation process of a single water quality factor, the evaluation process of nitrate is now selected as an example. The measured value of nitrate is 4mg / L, the optimal limit of nitrate in the water quality standard is 0mg / L, and the most listed limit is 10mg / L. Therefore, the median value of nitrate single factor evaluation is:

The invention discloses a classification variable weight drinking water quality online evaluation method based on the efficacy coefficient method, which is characterized in that it comprises the following steps: combining the drinking water national standards and industry standards to classify the drinking water quality evaluation factors and determining the optimal value of each factor The best limit and the worst limit; use the efficacy coefficient method combined with the measured drinking water quality data to conduct single-factor water quality evaluation; conduct comprehensive water quality evaluation within the category; During the evaluation process, the weight of this category in the comprehensive evaluation of drinking water quality; make a comprehensive evaluation of drinking water quality; give an evaluation of the health of drinking water in the pipe network. Advantages: Considering the time and space distribution rules of drinking water quality monitoring, creatively apply the efficacy coefficient method, classification algorithm and variable weight algorithm to the water quality evaluation work. It fills the gap in the field of drinking water quality evaluation.
Description
technical field [0001] The invention relates to an online evaluation method of drinking water quality with classification and variable weight based on an efficacy coefficient method, and belongs to the technical field of water quality evaluation. Background technique [0002] Under the new situation of "urban-rural integrated water supply", how to ensure the safety of drinking water for urban and rural residents and improve the management level of drinking water production, transportation and sales has become an important issue. Drinking water quality evaluation is the basis of drinking water supervision and management, and it is both the "starting link" and the "end link". Doing a good job in the evaluation of drinking water quality is crucial to both highlighting the ability of the management department to govern and to the public safety of the masses of users. [0003] At present, there are many evaluation methods for surface water quality in my country, which can be rou...
