Embodiment 1

[0079] This embodiment provides a water supply method for combined secondary water supply and storage equipment. The combined secondary water supply and storage equipment includes a control system, a low-level water tank 4 and at least one high-level water tank. A flow meter and an automatic valve 2 are provided at the water end, a flow meter is provided at the water outlet of the low water tank 4 and the water outlet of each high water tank, and water volume detection equipment is provided in the low water tank 4 and in each high water tank; A water pump is provided at the water inlet end of each elevated water tank; the control system includes an external forced controller 15 and an intelligent controller 1, and the intelligent controller 1 includes a data acquisition unit 16, a data storage unit 17, a data processing unit 18 and a control system. Unit 19, data acquisition unit 16 are connected with all water quantity detection equipments and all flowmeters respectively by wi...

Embodiment 2

[0152] On the basis of Embodiment 1, this embodiment will be further described in combination with specific data, and the volume of a certain high-level water tank A is set to be 4×3×3=36m 3 , then the conversion coefficient for converting the water level data into retained water volume is 0.12; the volume of the high-level water tank B is 4×3.5×3=42m 3 , then the conversion coefficient for converting water level data into retained water volume is 0.14, and the volume of the low-level water tank is 6×4×3=72m 3 , then the conversion coefficient for converting water level data into retained water volume is 0.24; W b / i with are the retained water volumes of the high-level water tank and low-level water tank at the beginning of time period i obtained through real-time detection and conversion, and the unit is m 3 . therefore,

[0153] For high water tank A: W b / i =0.12×H

[0154] For high tank B: W b / i =0.14×H

[0155] For low tanks:

[0156] Among them, H in the formu...

Abstract

The invention discloses a water supply method for combined secondary water supply water storage equipment. The water supply method for combined secondary water supply water storage equipmentcomprises the following steps that 1, the theoretical outlet flow rate A of the high water tank at different time periods of the day is calculated; 2,the theoretical amount of water remaining in the high tank at the beginning of a day at different times in a given dwell time is calculated; 3,the theoretical inlet flow and correct inlet flow A for the high water tank at different times of the day are calculated; 4,the specific time that the open pump needs to be shut down at different times of the day is calculated; 5,the corrected inlet flow rate of the lower tank at different times of the day is calculated; 6, the specific moment when the open automatic valve needs to be closed at different times of the day is calculated. According to thewater supply method for combined secondary water supply water storage equipment, water can be quantitatively supplied to the high and low water tanks, and the problem of quantitatively controlling the residence time of the tap water in the water storage equipment and reducing the risk of the microbial index exceeding the standard caused by the long residence time of the tap water in the water storage equipment are solved.

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 water supply method for combined secondary water supply and storage equipment. Background technique [0002] At present, most of the disinfection of urban drinking water (commonly known as tap water) in my country adopts chlorine disinfection. The outstanding advantage of chlorine disinfection method is that residual chlorine has a continuous disinfection effect. Residual chlorine refers to the amount of chlorine remaining in water after chlorine is added for a certain period of time during disinfection. The concentration of residual chlorine in the urban water supply network system will gradually decay over time, and maintaining a sufficient concentration of residual chlorine in the urban water supply network system can ensure that the microorganisms in tap water are controlled within the acceptable range. [0003] Secondary wat...
