Embodiment 1

[0021] Taking Daphnia as the experimental animal, the effects of four different drinking water on the survival period of mice were explored,

[0022] Materials: 90mm plastic petri dish, plastic dropper, slide glass, yeast medium (0.2g / L), optical microscope, etc.

[0023] method

[0024] 1. Experiment preparation: put the larger Daphnia in the same petri dish, observe whether the young fleas are produced every day, and use the young fleas produced on the same day for grouping.

[0025] 2. Grouping: Divide the Daphnia with the same growth condition into four groups, with 10 Daphnia in each group, and put the Daphnia in the same group in the same petri dish;

[0026] Add 18mL of yeast culture medium to the petri dishes of each group, and add 2mL of test water to the petri dishes of each group. The test water of each group is pure water, tap water, mineral water and purified water respectively. Let the water of each group The fleas were free to drink the corresponding test wate...

Embodiment 2

[0033] Taking mice as experimental animals, the effect of three different drinking water on the survival period of mice was explored.

[0034] 1. Materials and methods

[0035] 1. Experimental animals 60 3-week-old clean-grade ICR mice, half male and half male, male body weight 14-18g, provided by the Experimental Animal Center of Fujian Medical University, license number: SCXK (Fujian) 2012-0001. Raise them in a clean animal experiment room with an ambient temperature of (22±2)°C and an ambient relative humidity of (55±15)%. The maintenance feed was purchased from Beijing Huafukang Biotechnology Co., Ltd.

[0036] 2. Main reagents and instruments Tap water (Fuzhou municipal water supply), pure water (Laboratory of School of Pharmacology, Fujian Medical University), high metasilicate natural mineral water (Fujian Runhe Mineral Water Co., Ltd.), all drinking water conform to the corresponding National drinking water quality standards. JM20002 electronic balance (Xu Yao Jimin...

Abstract

The invention discloses a biological testing method for comprehensively evaluating the water quality of drinking water. The biological testing method comprises the following steps of dividing water fleas into a plurality of groups, wherein the number of the water fleas of all groups is the same, and the water fleas in the same group are put into the same culture dish; adding equivalent same culture media in the culture dishes in all groups, adding equivalent different tested water, and enabling the water fleas in each group to freely drink the corresponding tested water of each group; feeding the water fleas in each group for once every day, replacing the tested water for each group for once every day, observing and recording death situations of the water fleas every 24 hours, and removing dead water fleas and proliferous young water fleas; accurately recording death time of each water flea, and comparing the average survival time of the water fleas in each group, thus evaluating the water quality of the tested water in each group. According to the biological testing method for comprehensively evaluating the water quality of the drinking water, disclosed by the invention, a method and a system which are used for evaluating the water quality of domestic drinking water are established, the testing method is simple and feasible, and the level of the water quality can be quickly and accurately determined.

Description

technical field [0001] The invention relates to a method for testing water quality, in particular to a biological testing method for comprehensively evaluating drinking water quality. Background technique [0002] Water is the most abundant substance in the body. It is not only one of the important nutrients for maintaining life, but also contributes to the chemical reactions of various substances in the body, material transfer and energy exchange, and participates in the metabolism of all substances in the body. Drinking water is an indispensable part in people's daily life, and it is closely related to people's health. [0003] With the development of social economy and the improvement of people's living standards, people have increasingly diversified choices of drinking water. In addition to ordinary tap water, various new types of drinking water on the market are chosen by more and more people as the source of daily drinking water because of their good hygienic quality ...
