Problems solved by technology

But in actual operation, when the filtration system filters out 1 liter of pure water, 2-6 liters of waste water will be produced at the same time, and then the impurities in the water, including minerals, will be taken away by the waste water, otherwise too many impurities or too high a concentration of minerals will cause serious problems. Clogging the reverse osmosis (RO) membrane or nanofiltration membrane in the water filtration system makes it ineffective
In the civil water treatment system, the above-mentioned waste water is generally discharged directly, resulting in a serious waste of water resources.

Embodiment 1

[0021] Such as figure 1 As shown, the present embodiment is provided with a water supply three-way pipe 4 at the water inlet of the municipal water source. One branch of the tee pipe 4 is provided with a water filtration system 6, the water filtration system 6 is a drinking water filtration system, which can filter the municipal water source, so that the water that finally flows into the user end can be directly drunk, forming the drinking water for the user End 7. Between the water inlet passage of the described water filtration system 6 and its waste water outlet, be provided with a bypass waste water return pipeline, be connected with the water inlet passage of the water filtration system 6 through a backflow tee pipe 2, also install on the waste water return pipeline There is a flow compensation valve 8, which can compensate the pressure of the system, so that when the waste water flows back into the system, it will not be affected by the flow fluctuation caused by the fl...

Embodiment 2

[0031] Such as figure 2 As shown, the second embodiment is based on the first embodiment, and a waste water discharge valve 10 is also branched on the waste water return pipeline between the water filtration system 6 and the flow compensation valve 8, specifically between the flow compensation valve 8 and the flow compensation valve 8. The pipeline connected between the waste water discharge valves 10 is provided with a blowdown tee pipe 9, the waste water discharge valve 10 is connected with the blowdown tee pipe 9, and the waste water discharge valve 10 selects a high-concentration waste water discharge electromagnetic valve. If the user does not use the user's sanitary water system 5 for a long time, the concentration of wastewater in the system will be very high. At this time, the high-concentration wastewater discharge solenoid valve can detect high-concentration wastewater and discharge it automatically to prevent pipeline blockage.

Abstract

A water treatment system with reusable waste water, comprising a water filter system set on the water supply pipeline leading to the drinking water end of the user, characterized in that: between the water inlet channel and the waste water outlet of the water filter system, there is a A bypass waste water return line, which is equipped with a flow compensation valve; on the water supply line, there is also a pressure limiting valve, and the waste water return line is connected with the pipeline between the water filtration system and the pressure limiting valve , the pressure limiting value of the pressure limiting valve is lower than the pressure value of the waste water return pipeline. On the water inlet pipeline of the water filtration system, there is a user's sanitary water terminal next to it, and a waste water discharge valve is branched from the waste water return pipeline, which is located next to the flow compensation valve and the pipeline connected to the water filtration system. A water container is also arranged on the water inlet pipeline of the water filtration system, and the primary filter material can also be filled in the water container. The invention can reuse the waste water that was directly discharged outside in the water treatment system, which reduces user costs and saves water resources.

Description

【Technical field】 [0001] The invention relates to a water treatment system, in particular to a water treatment system capable of reusing waste water produced during water filtration by a civil reverse osmosis (RO) water filtration system or a nanofiltration system. 【Background technique】 [0002] In the existing water purification treatment system, if you want to obtain pure water, you can choose a reverse osmosis (RO) water filtration system or a nanofiltration system to filter out impurities such as heavy metals, viruses, bacteria, chemicals, and minerals in the water. Only pure water and a small amount of mineral ions beneficial to the human body dispersed in the water are reserved for human consumption. But in actual operation, when the filtration system filters out 1 liter of pure water, 2-6 liters of waste water will be produced at the same time, and then the impurities in the water, including minerals, will be taken away by the waste water, otherwise too many impuriti...
