Technical Field

Background

Water is a source of life, is a life pulse for social and economic development and is a fixed foundation for human development. The water on earth, although in huge quantities, can be directly utilized by human production and life, but is few.

The cost of seawater desalination is composed of energy consumption cost, equipment consumption, personnel cost, medicament cost and the like, wherein the energy consumption cost accounts for the highest proportion of the total cost, and most islands have no heat source, so the production cost is further increased by adopting a thermal method for seawater desalination. At present, a reverse osmosis membrane process is mainly adopted for sea water desalination in islands, and energy is supplied as electric energy. Most islands have no power plants, and the electric energy is transmitted by the continent; even if a power plant is built on the island, the power supply is not very sufficient. A part of limited electric energy is used for sea water desalination, and although the problem of lack of fresh water is relieved, the shortage of electricity for residents on the island is bound to be caused. Therefore, the single barrier of the energy mode for seawater desalination must be broken, and the hydropower requirements of residents on the island can be met at the same time. At present, the automation degree of the seawater desalination equipment is not high, and the maintenance of the equipment needs the field operation of professional personnel. Compared with the offshore region on the continent, the island is inconvenient to transport, and once equipment fails, the response time of personnel for repairing is long, so that the production and the life on the island are seriously influenced.
