The invention relates to a little-waste-water energy-saving type RO (reverse osmosis) water purifier which comprises a first-level filter device, a second-level filter device, a third-level filter device, a reflux device, an anti-pollution RO membrane filter device, a fourth-level filter device and a water storage barrel. A pulse pump is controlled by a pulse procedure to work; aiming at internally flushing the membrane surface of an RO membrane cavity, attachments depositing on the membrane surface and crystalline generated during work are effectively removed, so that the service life of the RO membrane is prolonged; by means of a self-cleaning discharge valve, a self-cleaning state can be automatically achieved when startup and shutdown is lower than a set critical point of a work range, and thus, a waste water proportioner is prevented from being plugged; concentrated water can flow back in front of the water pump through the reflux device and then is mixed with raw water to be utilized again, so that conditions of emission reduction and water conservation are met, and waste water ratio is reduced; by means of using reverse osmosis and using the anti-pollution membrane and an anti-scale amorphous carbon filter element, a water purification effect is effectively improved, and service life is prolonged.
Description
technical field [0001] The invention relates to household water purification treatment equipment, in particular to micro-wastewater energy-saving RO reverse osmosis water purifiers. Background technique [0002] Water is the source of life, and people cannot do without water in production and life. In ancient times, people lived by the water and lived by the water. People obtain water sources artificially for daily drinking and agricultural irrigation. Now with the continuous progress of industrialization, the water supply system is becoming more and more perfect. Modern industrial pollution, domestic pollution, agricultural pollution and other pollution all affect the water around us all the time. Therefore, how to obtain safe and healthy drinking water has become a problem that people pay more and more attention to. [0003] The problem of water pollution is particularly prominent in many poor countries, as well as in remote rural areas, mountainous areas and areas wit...
