Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like figure 1 , figure 2 As shown, the present invention provides a method for measuring the living water consumption of urban residents, comprising the following steps:

[0020] Step S10: According to the water supply pipeline (the general habit of laying domestic pipelines in my country) and the user's water use behavior, the urban domestic water is divided into kitchen water, shower water, washing water, washing machine water, toilet water and other water (such as mopping, greening, etc.). Plant water, etc.) six water modules.

[0021] Step S20, laying water metering equipment (such as a water meter) C at the water inlet pipe of each water module above-mentioned respectively 11 , C 12 , C 13 , C 14 , C 15 , C 16 , and arrange drainage metering equipment C at the drainage pipes of each water module. 21 , C 22 , C 23 , C 24 ...

Abstract

The invention discloses a calculation method for domestic water consumption of urban residents. The calculation method comprises the following steps: according to a water supply pipeline and water utilization behaviors of users, dividing urban domestic water into six water utilization modules including water for kitchens, water for showering, water for washing, water for a washing machine, water for a closestool and water with other purposes; a water inlet pipe of each water utilization module is provided with water utilization metering equipment; a water discharging pipe of each water utilization module is provided with water discharging metering equipment; according to metering data of each set of the water utilization metering equipment and each set of the water discharging metering equipment and a water balance principle, calculating domestic water consumption quantity of the residents and water consumption quantity of each person. According to the calculation method, the urban domestic water of each house is divided into the six water utilization modules according to a laying habit of the water supply pipeline and the water utilization behaviors of the users, and water discharging quantity of the six water utilization modules is metered through the metering equipment respectively, so that the water consumption quantity of urban life is accurately calculated and supports are provided for calculating pollutant discharging quantity of the urban life.

Description

technical field [0001] The invention relates to the measurement and calculation of urban domestic water consumption, in particular to a calculation method for urban residents' domestic water consumption. Background technique [0002] Nowadays, the proportion of urban residents' domestic water consumption in the total urban water consumption is increasing, and the residents' living water consumption is the key link to measure the real water saving of the city. According to the principle of water balance, that is, water consumption = water consumption - drainage. At present, the domestic water consumption of residents is basically determined by measuring water meters. The domestic water consumption of residents is usually calculated by using all the tap water supply in a large area and the amount of sewage treated by the sewage treatment plant. Factors such as these cannot be accurately measured and calculated, and the error of the calculated residential water consumption is v...
