High-quality water supply system of piped direct drinking water

Abstract

The invention discloses a high-quality water supply system of piped direct drinking water. A water supply pipe is provided with a supplied water filtering device, the supplied water filtering device is connected with a direct drinking water tank, the direct drinking water tank is connected with a terminal drinking water supply device, the supplied water filtering device is also connected with a wastewater recovery tank, an ultraviolet sterilizer is connected between the supplied water filtering device and the direct drinking water tank, the water outlet tube of the direct drinking water tank is provided with a water mineralizing device, a direct drinking water pipe network is connected with a return water pipeline, the return water pipeline is provided with a return water retreatment device, and the water outlet end of the return water pipeline is connected to the direct drinking water tank; and the wastewater recovery tank is connected with a wastewater filtering device, the wastewater filtering device is connected with a secondary water supply tank, a water supply tube is connected with a water feeding tube, the water outlet tube of the water feeding tube and the water outlet tube of the secondary water supply tank are commonly connected with a washing water pipe network, and the washing water pipe network is connected with a terminal washing water device. The system has the advantages of prevention of water quality decreasing induced by accumulation of water in a pipeline, improvement of the quality of drinking water, and effective utilization of water resources.

Description

technical field [0001] The invention relates to a high-quality water supply system for direct drinking water through pipes. Background technique [0002] With the improvement of the living material level of the masses, people have higher and higher requirements for the quality of drinking water, and the quality of drinking water needs to be improved in the household water supply system. Existing households generally use household water supply devices, which are directly connected to drinking water pipes with filter devices (including RO membrane filters, activated carbon filters, etc.), and the quality of purified water discharged from the filter devices is much higher. The quality of tap water, but this kind of household water supply device installed separately has a simple structure, it is difficult to completely purify the water flow, and the quality of the purified water is low. The existing direct drinking water is connected to a large-scale filter device and a minerali...

Problems solved by technology

Existing households generally use household water supply devices, which are directly connected to drinking water pipes with filtering devices (including RO membrane filters, activated carbon filters, etc.), and the quality of purified water discharged from the filtering devices is much higher. The quality of tap water, but this kind of separate household water supply device has a simple structure, it is difficult to completely purify the water flow, and the quality of the purified water is low. The existing pipeline direct drinking water is connected to a large-scale filter device and a mineralization device on the tap water network. In order to improve the quality of water supply, since this kind of direct drinking water belongs to the direct water supply for residents, when the user does not use the direct drinking water, there will be a backlog of part of the water flow in the pipeline, which will cause the water quality to decline, resulting in unstable supply of direct drinking water. Conducive to the improvement of people's health and quality of life

And the waste water produced after the above-mentioned purified tap water is all discharged freely, resulting in a great waste of water resources, especially when RO membrane filter is used for filtration, the amount of waste water generated after using tap water to filter is far greater than the drinking water produced. With such scarce resources, waste water must be used efficiently to avoid maximum waste
