Method for quantitatively supplying water to secondary water supply tank based on actual water retention

Abstract

The invention discloses a method for quantitatively supplying water to a secondary water supply tank based on actual water retention. The method comprises the following steps: 1, theoretical outlet flows in different time periods of a day are calculated; 2, the theoretical water retention of the water storage equipment at the starting time of different time periods in one day under the condition of given retention time is calculated; 3, the actual water retention of the water tank is calculated, and the inlet flow of the water tank in different time periods of one day is calculated by the control system according to the theoretical outlet flow, the theoretical water retention and the actual water retention; 4, water supply of one day is completed according to the result of the third step. According to the method, the actual situation that the water tank has a spherical segment is fully considered, and the actual water retention of the water tank can be accurately calculated, so that the retention time of tap water in the high-level water tank or the low-level water tank can be quantitatively controlled based on the actual water retention; the risk that the microbial indicator exceeds the standard due to the fact that the tap water stays in the water tank for a long time is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of secondary water supply of an urban water supply pipe network system, in particular to a method for quantitatively supplying water to a secondary water supply tank based on the actual retained water 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 ...

Problems solved by technology

The lack of a ball can effectively increase the strength of the water tank, but at present, when measuring and calculating the retained water volume of a water tank, the water level of the water tank is usually multiplied by the longitudinal section of the water tank without the lack of a ball, without considering the amount of water corresponding to the part of the ball. As a result, there is usually an error of about 5% in the calculated retained water volume, which is not conducive to the precise control of the water supply of the water tank
