Problems solved by technology

But so far, the utilization of the residual chlorine meter in the prior art is still simply using the residual chlorine meter to measure the residual chlorine concentration, and there is no concept or method for evaluating the cleanliness of the water tank through the change of the residual chlorine concentration

Embodiment 1

[0144] The invention provides a method for evaluating the cleanliness of a secondary water supply tank, comprising the following steps:

[0145] Step 1: Calculate the sample attenuation coefficient within the evaluation analysis time range and the water temperature corresponding to the sample attenuation coefficient;

[0146] In this step, the sample attenuation coefficient refers to the attenuation coefficient within the evaluation and analysis time range, which is characterized in that the initial time and the end time for calculating the attenuation coefficient are both within the evaluation and analysis time range, and the evaluation and analysis time range is artificially set. A period of time designated for evaluating and analyzing the cleanliness of the tank.

[0147] Step 2: Calculate the theoretical attenuation coefficient and risk attenuation coefficient corresponding to the sample attenuation coefficient, and the theoretical attenuation coefficient is calculated by ...

Embodiment 2

[0275] This embodiment is further described in conjunction with specific actual data on the basis of Example 1, specifically: select a high-level water tank in an industrial park to install the corresponding equipment of the present invention, the volume of this high-level water tank is 14 tons, and the material is stainless steel. The water intake is controlled by a float valve, and the specific structure of the corresponding equipment of the present invention is as follows: figure 1 , 2 shown. On September 8, 2019, the water tank was cleaned once, and the water tank was cleaned and put into use at 1040 points on that day. Since September 11, 2019, an evaluation analysis was carried out at 0 points and 720 points each day. This time The evaluation analysis starts from 720 points on September 23, 2019, and includes the following steps:

[0276] Step 1: Calculate the sample attenuation coefficient and the water temperature corresponding to the sample attenuation coefficient w...

Embodiment 3

[0413] This embodiment is to verify the accuracy of the present invention by performing microbial detection on the tap water in the evaluated water tank on the basis of Example 2, specifically: on September 8, 2019, a high-level water tank in the industrial park was cleaned, At 17:20 on the same day, it was cleaned and put into use. At the same time, the management system for evaluating and analyzing the cleanliness of the water tank in the present invention began to operate immediately. Samples were taken from the water tank at 8:32 on September 9, 2019, and the samples were tested at 9:10 on the same day. The inspection item is the total number of bacterial colonies, and the inspection basis is GB / T5750.12-2006. The inspection result was "not detected" on September 11, 2019. The inspection results are as follows: image 3 As shown, it proves that the cleaning of the water tank is effective; at 12:10 on September 23, 2019, the intelligent controller of the evaluation analysis ...

Abstract

The invention discloses a method for evaluating the cleaning condition of a secondary water supply tank. The method comprises the following steps: step 1, calculating a sample attenuation coefficientin an evaluation analysis time range and a water temperature corresponding to the sample attenuation coefficient; 2, calculating a theoretical attenuation coefficient and a risk attenuation coefficient corresponding to the sample attenuation coefficient, wherein the theoretical attenuation coefficient is obtained by calculating a regression equation of the clean attenuation coefficient along withthe change of the water temperature and the initial residual chlorine concentration, which is obtained by using a regression analysis method; and 3, pairing and comparing the sample attenuation coefficients with the corresponding risk attenuation coefficients, and if the mean value of the sample attenuation coefficients is significantly greater than the mean value of the corresponding risk attenuation coefficients, judging that the cleaning condition of the water tank is significantly worsened. The technical problem to be solved by the invention is how to conveniently and timely evaluate the cleaning condition of the water tank so as to ensure that qualified tap water is provided for users.

Description

technical field [0001] The invention relates to the field of secondary water supply of urban water supply pipe network systems, in particular to a method for evaluating the cleanliness of a secondary water supply tank, which is used for evaluating the cleanliness of the secondary water supply tank. Background technique [0002] At present, my country's supply of drinking water (commonly known as tap water) for urban high-rise building users is implemented through secondary water supply. Secondary water supply refers to the way of supplying water to users or self-use through pipelines through storage, pressurization and other facilities when the water pressure and water volume requirements of civil and industrial buildings exceed the capacity of urban public water supply or self-built water supply pipe network . As part of the urban water supply network system, secondary water supply facilities include water storage equipment, pressurization equipment and pipelines. Water st...
