Problems solved by technology

[0003] The process of traditional seawater desalination equipment is lengthy, and the early pretreatment such as intermittent chlorination process, adding scale inhibitor process, cumbersome operation, high operating cost, and poor sterilization effect make the later membrane system easy to become a breeding ground for bacteria, which seriously reduces the The service life of the membrane and it is difficult to ensure efficient and stable effluent water quality

Abstract

The invention provides a multi-membrane-method sea water desalination integrated device. According to the multi-membrane-method sea water desalination integrated device, a novel multi-membrane-method sea water desalination integrated technology is created by coupling microfiltration, ultrafiltration, frequent electrodialysis reversal and active carbon optimizing, and aims at solving the problems of membrane pollution and the like in the sea water desalination process; an ultrafiltration membrane with high pollution resistance is adopted for a pre-treatment system, and the ultrafiltration membrane and an electric-driving homogeneous membrane form a double-membrane system, so that the system is more stable in running, the service life of the system is prolonged, and it is guaranteed that the quality of yielded water meets a tap water standard; the sea water desalination integrated technology is a novel sea water desalination technology.

Description

technical field [0001] The invention belongs to the field of seawater desalination treatment, and in particular relates to a multi-membrane seawater desalination integrated device. Background technique [0002] With the rapid development of my country's economy, the consumption of water resources has doubled, and fresh water resources are seriously insufficient. At present, my country's water shortage in normal years is nearly 40 billion cubic meters, of which the irrigation water shortage is about 30 billion cubic meters. Among the more than 660 cities in the country, more than 400 cities are short of water, of which 108 are seriously short of water. The shortage of fresh water resources and even the water crisis are one of the biggest bottlenecks in the sustainable development of my country's economy and society. Especially in coastal areas, the scarcity of water and other resources has seriously restricted the sustainable development of society and economy and the secur...
