technical field

The utility model belongs to the technical field of water purification and relates to a direct drinking water treatment device, in particular to an RO membrane water purification device without waste water.

Background technique

City-supplied tap water is transported to household users through pipelines, which inevitably causes secondary pollution of water quality during the transport process, so that the terminal tap water cannot meet the national drinking water hygiene standards, and users cannot drink it directly. At the same time, tap water may be polluted by pipelines, high-level water storage tanks, irregular pipeline construction or emergency repairs during the transportation process. Secondary pollution usually increases the content of solid particles, bacteria and heavy metals in water, and long-term drinking will cause harm to human health.

At present, most of the water purification products on the market use reverse osmosis membrane (RO) as the core filter material, and reverse osmosis membrane technology is a membrane separation and filtration technology that uses pressure difference as power. Its pore size is as small as 0.1 nanometers. H ₂ O can pass through the RO membrane, but most of the impurities such as inorganic salts, heavy metal ions, organics, colloids, bacteria, viruses, etc. cannot pass through the RO membrane, so that the permeable pure water and the impermeable concentrated water are separated. , to achieve the purpose of purifying water. In this working process, the volume ratio of pure water and concentrated water is generally 1:2, and the utilization rate of raw water (tap water before purification) is only about 30%. cause serious waste of water resources. As freshwater resources are increasingly scarce today, the extremely low water utilization rate of this type of equipment is seriously inconsistent with the energy-saving and water-saving concepts and requirements vigorously advocated by the state.

Working principle: when in use, the water replenishment solenoid valve 1 is directly connected to the municipal tap water, the raw water enters the water tank 2, and the raw water is filtered through the second filter 8 and the third filter 9 in turn by the action of the self-priming pump 11, and then enters the water tank. The RO membrane filter 12 performs deep separation treatment, the separated waste water is returned to the water tank 2 through the concentrated water pipeline 10 for recirculation and filtration, the separated pure water enters the pressure water storage tank 16 through the pipeline, and the pure water finally passes through the pure water outlet pipeline. After the water is discharged, it can be directly consumed, and the circulating pump 6 and the first filter will decide whether to work according to the level of the TDS value of the water tank 2 .
