Residence secondary water supply water age optimization system and method

Abstract

The invention discloses a residence secondary water supply water age optimization system and method. The system comprises a water pool / tank (1), the water pool / tank (1) is provided with a water inlet,a water outlet and a water drainage port, a water inlet electromagnetic valve (2) and a water drainage electromagnetic valve (3) are arranged at the water inlet and the water drainage port of the water pool / tank (1) respectively, a liquid level sensor (4) is arranged inside the water pool / tank (1), an on-line residual chlorine instrument (5) is arranged at the water outlet, the water inlet electromagnetic valve (2), the water drainage electromagnetic valve (3), the liquid level sensor (4) and the on-line residual chlorine instrument (5) are connected to a control cabinet (6), the water inletelectromagnetic valve (2) is controlled by the control cabinet (6) according to signals collected by the liquid level sensor (4), and the water drainage electromagnetic valve (3) is controlled by thecontrol cabinet (6) according to signals collected by the on-line residual chlorine instrument (5) so as to realize automatic circulation control over the water body of the water pool / tank (1).

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a system and method for optimizing the water age of secondary water supply for residential buildings. Background technique [0002] The secondary water supply is the final link of the water supply system. Water storage facilities such as pools (tanks) have always been the management focus of water supply companies. Facing the higher requirements of urban water supply, solving the problem of secondary water supply quality has become the key to ensuring the safety of drinking water quality. The essential. [0003] Due to the influence of many factors, it is often difficult to control the effluent water quality of low-level water tanks and high-level water tanks, especially the design volume of some water tanks (tanks) is too large, and most of them use mechanical float valves to control the operation mode of replenishing water as needed, resulting in The water body ...

Problems solved by technology

[0003] Due to the influence of many factors, it is often difficult to control the effluent water quality of low-level water tanks and high-level water tanks. In particular, the design volume of some water tanks (tanks) is too large, and most of them use mechanical float valves to control the operation mode of replenishing water as needed, resulting in The water body stays still in the pool (tank) for a long time and does not flow for a long time. If the residence time is too long, the attenuation rate of the disinfectant will increase, which will lead to the growth of microorganisms and the deterioration of water quality. There will be risks of microbial safety and affect the safety of residents' water use. It has become a prominent problem facing the water supply industry.
