However, a large amount of wastewater is inevitably generated in the water purification process. If this type of wastewater is directly discharged, it will not only cause a waste of water resources, but also deviate from our concept of green development. At present, most communities use a single tap water supply, and some areas have begun to drink piped drinking water, that is, using a tap water pipeline and a direct drinking water pipeline to supply water to users.

The water purification module includes an ultraviolet sterilization device 11, a water purification tank 12, a water purification network 17, a water purification outlet solenoid valve 18, and a water purification outlet 19 which are connected in sequence; the concentrated water module includes a quartz sand filter 13, an activated carbon filter 14, a softener 15, a concentrated water tank 16, a concentrated water network 20, a concentrated water outlet solenoid valve 21, and a concentrated water outlet 22 which are connected in sequence; a quartz sand filter 5, an activated carbon filter 6, a softener 7, and a precision filter 8 constitute a pretreatment module of this system; in addition, the water inlet solenoid valve 2, the water inlet pump 4, the high-pressure pump 9, the water purification outlet solenoid valve 18, and the concentrated water outlet solenoid valve 21 are electrically connected to the PLC controller 23 respectively.
[0016] A more detailed explanation is:
[0017] The utility model provides a central water purification system for separating water supply from clean water and concentrated water pipelines to solve the problem of wastewater generated during the purification of tap water. First, municipal tap water enters the raw water tank 3 from the water inlet 1 under the action of the water inlet solenoid valve 2, and then passes through the pretreatment system under the action of the water inlet pump 4, and is pretreated in turn under the action of the quartz sand filter 5, the activated carbon filter 6, the softener 7, and the precision filter 8 to remove colloid substances, some ionic substances, dissolved gases and microorganisms in the water; then, it enters the membrane filtration device 10 under the action of the high-pressure pump to remove the remaining small molecules and microorganisms. The purified water enters the water purification module, and is further sterilized and disinfected in the ultraviolet sterilization device 11. Then, part of the purified water is temporarily stored in the clean water tank 12, and part of it flows out from the clean water outlet 19 at the user through the clean water pipe network 17 and the clean water outlet solenoid valve 18 for direct drinking by the user, which is safe and hygienic. The wastewater flowing out of the membrane filtration device 10 flows through the concentrated water treatment module, and the concentrated water is further pre-treated by the quartz sand filter 13, the activated carbon filter 14, and the softener 15 to reduce the content of various ionic colloids in the concentrated water. Part of the purified concentrated water is temporarily stored in the concentrated water tank 16, and part of it flows out from the concentrated water outlet 22 at the user's place through the concentrated water pipe network 20 under the action of the concentrated water outlet solenoid valve 21 for people to use for daily washing, effectively reducing the waste of water resources. The utility model uses tap water in different qualities, and divides tap water into direct drinking water and drinking water for daily use. It is not only safe and reliable, but also effectively solves the problem of a large amount of concentrated water generated during the water purification process, reduces the waste of water resources, and is green and energy-saving.
