Embodiment 1

[0074] This embodiment provides a quantitative water supply method for secondary water supply and storage equipment, which is suitable for quantitative water supply for secondary water supply and storage equipment with low-level water tanks as the water storage equipment and automatic valves as the water supply control equipment. Its structure is as follows figure 1 , 2 shown. Specifically, it includes the following steps:

[0075] Step 1. Use the outlet flowmeter to continuously detect the outlet flow of the water storage equipment in different time periods of the day. Specifically, it can continuously detect the outlet flow for 20-40 days. The theoretical egress flow for the time period.

[0076] In this step, the theoretical outlet flow calculation method is as follows: Divide a day into N time periods on average, use i to represent the sequence number of different time periods in a day, and use the outlet flow detected in the past E consecutive days for calculation, then...

Embodiment 2

[0117] On the basis of Example 1, this example will be further described in combination with specific data, and the water storage equipment of a real estate is set as a low-level water tank installed in the pump room, and its volume is 4×3.5×3=42m 3 , then the conversion coefficient α for converting water level data into retained water volume is 0.14, W b / i is the stored water volume of the low-level water tank at the beginning of time period i obtained through real-time detection and conversion, and the unit is m 3 .

[0118] Specifically: the calculation method of the theoretical outlet flow in the step 1 is: divide one day into 24 time periods on average, use i to represent the sequence number of different time periods in a day, and use the outlet flow detected for 30 consecutive days in the past to calculate, but:

Embodiment 3

[0156] This embodiment is applicable to the quantitative water supply for secondary water supply and storage equipment where the water storage equipment is a high-level water tank, the water supply control equipment is an ordinary water pump, and the ordinary water pump cannot operate accurately according to its rated flow rate. Its structure is as follows Figure 4 , 5 shown. Specifically, the quantitative water supply method includes the following steps:

[0157] Step 1. Use the outlet flowmeter to detect the outlet flow of the water storage equipment in different time periods of the day for several consecutive days. After the detection is completed, the control system calculates the theoretical outlet flow in different time periods of the day based on the detected outlet flow.

[0158] Step 2: The control system calculates the theoretical water retention volume of the water storage device at the beginning of different time periods of the day under the condition of a given ...

Abstract

The invention discloses a quantitative water supply method of secondary water supply and storage equipment. The quantitative water supply method comprises the following steps that 1, the theoretical outlet flow rate of different time periods of a day is calculated; 2, the theoretical water storage capacity of water storage equipment at the beginning moments of the different time periods of the day under the given residence time is calculated; 3, the inlet flow rate of the water storage equipment at the different time periods of the day is calculated; and 4, at the beginning moments of the different time periods of the day, a control system completes the water supply at the time by being matched with water supply control equipment according to the results of the step 3, and the water supply for the day is completed according to the cycle. According to the quantitative water supply method, the problem of quantificationally controlling the residence time of tap water in the water storage equipment (a high level water tank or a low level water tank) is solved, the risk of exceeding the standard of microbiological indicators caused by the too long residence time of the tap water in the water storage equipment is lowered to the maximum extent, meanwhile the implement is convenient, and the energy consumption, the maintenance cost and the running cost of the actual operation are very 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 quantitative water supply method for 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...
