Embodiment 1

[0160] The invention provides a method for judging the cleanliness of secondary water supply and storage equipment, comprising the following steps:

[0161] Step 1: Calculating the sample attenuation coefficient for judgment analysis and the water temperature corresponding to the sample attenuation coefficient.

[0162]In this step, the sample attenuation coefficient refers to the attenuation coefficient of the tap water stored in the water storage equipment within the evaluation and analysis time period, which is characterized in that the outflow time used to calculate the attenuation coefficient is within the evaluation and analysis time period, and the evaluation and analysis time period is An artificially set period of time dedicated to judging and analyzing the cleanliness of water storage equipment; the sample attenuation coefficient is preferably calculated under the condition that tap water flows out of the water storage equipment in the order in which it flows into the...

Embodiment 2

[0305] This embodiment is further described on the basis of embodiment 1 in conjunction with specific actual data, specifically: a stainless steel water tank with a volume of 33 cubic meters is selected as a secondary water supply and storage device in an industrial park, and its water intake passes through a float valve control, the specific structure is as figure 1 , 2 shown. Among them, the sample attenuation coefficient and cleaning attenuation coefficient involved in the judging process are all calculated under the condition that the tap water flows out of the water storage device in the order in which it flows into the water storage device. Under these conditions, the evaluation of the cleanliness of the secondary water supply and storage equipment includes the following steps:

[0306] Step 1: Calculating the sample attenuation coefficient for judgment analysis and the water temperature corresponding to the sample attenuation coefficient.

[0307] In this step, the c...

Embodiment 3

[0460] This embodiment is to verify the accuracy of the present invention by performing microbial detection on tap water in the judged water storage equipment on the basis of Example 2, specifically: a water storage equipment in an industrial park on August 4, 2019 Cleaning is completed and put into use at 18:40 on the same day. The management system for evaluating and analyzing the cleanliness of the water storage equipment in the present invention starts to run immediately. Samples are taken from the water storage equipment at 8:01 on August 5, 2019, and at 9:00 a.m. on the same day 15 The samples were inspected, the inspection item was the total number of bacterial colonies, and the inspection basis was GB / T5750.12-2006. On August 7, 2019, the inspection result was "not detected". The inspection results were as follows: image 3 As shown, it proves that the cleaning of the water storage equipment is effective; at 6:10 on August 11, 2019, the intelligent controller of the man...

Abstract

The invention discloses a method for judging a cleaning condition of secondary water supply and storage equipment. The method comprises the following steps: 1, calculating a sample attenuation coefficient for judgment and analysis 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 with the 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 coefficientswith 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 storage equipment is significantly worsened. The technical problem to be solved by the invention is how to conveniently and timely judge the cleaning condition of the water storage equipment 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 judging the cleanliness of secondary water supply and storage equipment, which is used for judging the cleanliness of the secondary water supply and storage equipment. Background technique [0002] At present, the supply of domestic drinking water (commonly known as tap water) to urban high-rise building users in my country is implemented through secondary water supply. Or self-built facility water supply pipeline network capacity, through storage, pressurization and other facilities to supply water to users or self-use water supply through pipelines. As part of the urban water supply network system, secondary water supply facilities include three parts: water storage equipment, pressurization equipment and pipelines. Secondary water supply and water storage equipment (hereinafter referred to as water storage equipment)...
