Description
Technical Field
The invention relates to the technical field of tap water treatment, in particular to a pressurized gas regeneration device and method.
Background
With the increasing situation of water resource shortage, the water quality condition is continuously worsened, the requirements of people on health and drinking water safety are continuously improved, and the requirements of China on water treatment technology are continuously improved. At present, the domestic water resource problem mainly exists in two aspects: safety issues for drinking water and treatment of sewage/wastewater.
Among them, the problems of drinking water treatment are mainly: (1) the water hardness is higher; (2) the pH of the water body is acidic; (3) the heavy metal in the water body exceeds the standard; (4) trace pollutants are excessive, such as arsenic, fluorine and the like; (5) eutrophication of water body, and exceeding the standard of total nitrogen and total phosphorus; (6) the salt content of the water body exceeds the standard. The prior drinking water treatment technology is lack of comprehensive treatment technology aiming at the problems, and membrane technology (ultrafiltration, nanofiltration and reverse osmosis) becomes the only treatment solution in the current market. The membrane process is complex to operate, needs a complex pretreatment process, has high operation energy consumption, high cost, weak pollution resistance, very low water production rate (50-75%), high initial cost, wide occupied area and great management and maintenance difficulty.
In the aspect of seawater desalination, the membrane technology has the unique advantages, but the application condition of the membrane technology is not ideal for tap water or drinking water treatment. The treatment process has strong selectivity of adsorption, ion exchange and the like for treating and removing specific pollutants, and is ideal with simple operation and running. For the technology, if the gas solution is reasonably used as a regenerant, the adding amount of chemicals can be greatly reduced, the production cost is reduced, the pollution discharge concentration and the total pollution discharge amount are reduced, and the secondary pollution is reduced. Compared with a membrane process, the adsorption and ion exchange can directionally remove low-concentration pollutants in a water body, and trace elements beneficial to a human body are reserved, so that the taste is improved, and the health of drinking water is ensured. Compared with the membrane technology, the initial construction cost of the process is greatly reduced, the operation cost is kept equivalent, the dosage is reduced, and the secondary pollution is avoided.
The problems of sewage treatment mainly include: (1) the chroma processing is incomplete; (2) the salinity is higher; (3) heavy metals; (4) trace contaminants. With the increasing shortage of water resources, the reuse of sewage will be a necessary trend. However, the current sewage recycling technology is very limited, and the membrane treatment technology is almost the only sewage recycling technology, which has the following defects: (1) the discharged sewage reaching the first-level A standard still contains a small amount of COD and ammonia nitrogen, and the membrane is easily polluted; (2) hardness ions in the sewage, such as but not limited to calcium and magnesium, can form scale on the surface of the membrane, so that pollution is caused; (3) if scaling type anions such as but not limited to sulfate ions exist in the sewage, scaling can be carried out on the surface of the membrane, so that pollution is caused; (4) the water production efficiency of the membrane process is about 60% on average, namely 40% of sewage is wasted as wastewater; (5) the membrane process requires a large amount of energy consumption; (6) the produced water is pure water, which often exceeds the water demand. The adsorption method or the ion exchange method can achieve the water production efficiency of more than 90 percent when used for treating and recycling sewage, the whole system is not easy to pollute, a complex and tedious pretreatment process is not needed, a large amount of energy is not needed to be consumed in the operation process, and the quality of the effluent can be regulated and controlled to a certain degree.
