Technology for preparing purified water by well process reverse osmosis

Abstract

The invention relates to a technology for preparing purified water by well process reverse osmosis. An apparatus for implementing the technology comprises a vertical well, a reverse osmosis chamber, areverse osmosis water tank, a water inlet pipe, a water outlet pipe, a pure water pipe, a connection pipe and a reverse osmosis assembly. The reverse osmosis chamber is arranged at a certain depth under the ground, pure water in raw water is separated through the reverse osmosis module by using the water depth pressure, and electric energy is only used for pumping the separated pure water to theground, so a large amount of electric energy is saved, and a high pressure pump and an energy recovery device are removed. Water shortage in China's cities is caused by a reason that water resources cannot be used as a drinking water source due to pollution, such as water shortage in Shanghai near the Yangtze River. A reverse osmosis technology for treating polluted river and lake water is formedby setting a reverse osmosis process in a traditional technology, and the river and lake water is freshwater, so the consumption of electricity is very low. Compared with traditional reverse osmosis technologies, the technology in the invention has the advantages of energy saving, high efficiency, suitableness for water plants and purified water production enterprises, solving of the problem of general shortage of water in China's cities, and meeting the demands of improved people's living standards for high water quality.

Description

technical field [0001] The technology relates to the field of preparing pure water by reverse osmosis technology. Background technique [0002] The water resource crisis has profoundly affected the world, and the world's demand for fresh water continues to increase. Our country even adopts the South-to-North Water Diversion Project to divert water. When the traditional reverse osmosis membrane technology is used for seawater desalination, it needs to exert pressure on all the seawater to generate energy consumption (in which the thickened seawater consumes energy for nothing). Moreover, the traditional reverse osmosis technology needs to add an energy recovery device to recover the energy added to the concentrated seawater, and use a high-pressure pump with high technical requirements, which makes the cost too high. In addition, my country's inland and coastal cities generally lack water. Although these cities are close to rivers and lakes, most of the water resources of r...

Moreover, pure water is basically harmless to the human body. Although it lacks minerals, 99% of the minerals people ingest are obtained from food, and the minerals obtained from drinking water are almost zero, and the minerals in the water are difficult to obtain. absorbed by the body

If the traditional reverse osmosis technology is used to process river and lake water to produce pure water, although the energy consumption is only a fraction or a tenth of that of seawater, the power consumption is still a bit large, and the water is a huge demand. Huge power consumption requires new technology to reduce power consumption
