Embodiment 1

[0061] This embodiment provides a water supply method for secondary water supply storage equipment with variable volume, such as figure 1 As shown, the equipment or devices used in the water supply method include variable volume water storage equipment, inlet flowmeters, outlet flowmeters, water volume detection equipment, water supply control equipment, intelligent controllers and external forced controllers. The intelligent controller includes a data acquisition unit, a data storage unit, a data processing unit and a control unit. The data acquisition unit is respectively connected to the water volume detection equipment, the inlet flowmeter and the outlet flowmeter by wire or wirelessly, and the data storage unit is respectively connected to the data acquisition unit, the data The processing unit is connected with the control unit, and the control unit is respectively connected with the data processing unit, the data storage unit, the external forced controller and the water...

Embodiment 2

[0116] On the basis of Example 1, this example is further described in conjunction with specific data, and the design effective volume of water storage equipment in a newly built building is set as 4×4×3=48m 3 , is designed to supply water to 240 households. In order to quantitatively control the residence time more effectively, the original water storage equipment of the newly built building is transformed into a volume-variable water storage equipment with 6 effective volume options, and 6 types of effective volume The volume increases sequentially, specifically as image 3 As shown, there are only 15 households in the initial period of occupancy, so the minimum effective volume Q1 of the variable-volume water storage equipment is selected to supply water to users, and the automatic valve selects a regulating valve that can adjust the flow rate, and the flow rate when it is opened is set to 2m 3 / h.

[0117] Under the above-mentioned conditions, the water supply method of t...

Abstract

The invention discloses a water supply method for a secondary water supply and storage device with variable volumes. The water supply method includes the following steps that (1) the water storage device with a plurality of effective volumes is arranged; (2) first, an average value of the theoretical outlet flow at different time periods of a day and the total outflow water yield of the day is calculated, and then the theoretical remained water yield of the water storage device at the beginning moments of the different time periods of the day is calculated; (3) the inlet flow of the water storage device at different time periods of the day is calculated; (4) a water supply control device supplies water to the water storage device according to results of the step (3); and (5) the volume proportion of the water storage device is calculated, and whether the effective volumes of the water storage device need to be changed or not is determined. According to the water supply method for the secondary water supply and storage device with the variable volumes, the difficult problem of quantitative control of the residence time of tap water in the water storage device of a new building is solved, the risk of excessive microbial indexes due to the too long residence time of the tap water in the water storage device of the new building is lowered, implementation is convenient, and the energy consumption and the maintenance and operating costs are all low.

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 secondary water supply storage equipment with variable volume. 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.
