Abstract

The invention relates to a seawater desalination system for removing boron by using electrodeionization, comprising a water pipe, a seawater pretreatment system, a seawater reverse osmosis desalting and boron-removing desalination system, an electrodeionization boron-removing desalination system and a seawater deep treatment system, wherein the seawater pretreatment system, the seawater reverse osmosis desalting and boron-removing desalination system, the electrodeionization boron-removing desalination system and the seawater deep treatment system are sequentially connected in series to the water pipe. The seawater desalination system is characterized in that a reverse osmosis technology and an electrodeionization technology are jointly used to remove boron in seawater with high efficiency and low consumption; with the adoption of the technologies, more than 99% of salt and more than 92% of boron in the seawater can be removed, so that produced water reaches Sanitary Standard for Drinking Water (GB5749-2006). The seawater desalination system for removing boron by using the electrodeionization has the advantages of small space occupation, low energy and agent consumption, low operation cost, safety and reliability for equipment operation and simplicity in maintenance.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a seawater desalination system using electrodeionization to remove boron. Background technique [0002] In the 21st century, water shortage has become a problem of sustainable social development faced by the whole world. Water resources are becoming a precious and scarce resource. The issue of water resources is not only a resource issue, but also a major strategic issue related to national economic and social sustainable development and long-term stability. Known as the "water polo", 70% of the earth's surface area is covered by oceans. Compared with the shortage of fresh water, seawater is almost an "inexhaustible" natural resource. 70% of the world's population lives within 120km of the sea. If seawater can be used as the basic water source for drinking water, the crisis of water resources will be fundamentally resolved. Therefore, seawater desalination will be an impor...
