The invention discloses an energy-saving, emission-reducing and water-purifying system. The system is characterized by comprising a raw water inlet, the raw water inlet is communicated with the waterinflow end of a composite filter element, the water outflow end of the composite filter element is connected with the water inflow end of a water inflow solenoid valve, the water outflow end of the water inflow solenoid valve is connected with the water inflow end of a booster pump, the water outflow end of the booster pump is connected with the water inflow end of an RO (reverse osmosis) membrane, the pure water outlet of the RO membrane is communicated with the water inflow end of post-positioned active carbon, the water outflow end of the post-positioned active carbon is connected with thepure water outlet, the waste water outlet of the RO membrane is connected with two pipelines, one pipeline is connected with the waste water outlet through a second waste water ratio, and the other pipeline is connected with the water inflow end of the booster pump through a first waste water ratio. According to the energy-saving, emission-reducing and water-purifying system, the structure is simple and practical, a part of waste water is reutilized and transformed into pure water, the emission of the waste water is reduced, washing circulating current generated by the waste water is used forwashing the RO membrane for the second time, and the service life of the RO membrane is prolonged.
Description
technical field [0001] The invention relates to an energy-saving and emission-reducing pure water system, which belongs to the technical field of water purifiers in daily necessities. Background technique [0002] In today's serious environmental pollution, water resources are related to our health. With the strength of the national economy and the pursuit of healthy life, water purification equipment has been favored by consumers once it enters the market. [0003] It is reported that the water purification industry has issued the first mandatory standard "Reverse Osmosis Water Purifier Water Efficiency Limits and Water Efficiency Grades", which will be officially implemented in 2018. According to reports, the standard has made clear provisions in terms of energy efficiency. For example, for water efficiency detection, calculation methods, classification and water production rate, etc. The water efficiency grade is divided into five grades, and the limit value is stipula...
