Combined with the seawater desalination project of Hebei Datang Wangtan power plant,it introduces the construction arrangement,main construction plans and debugging plans of the key procedures in electrical system and seawater desalination control system,which is a guidance for the future construction of this field.

Structure design of mobile seawater desalination device;

Research situation and development of seawater desalination plant for ships;

Selection of pretreatment system of seawater desalination;

Discussion on nearshore desalination in Tianjing;

Off design performance analysis of desalination plant with low temperature distillation;

Study on the application of the reverse osmosis desalination technology in ship;

The application of ceramic membranes in the pretreatment of seawater desalinization;

Effect on cost of seawater desalinization of circular economy modes

The paper puts forward the linked pattern of salinity balance by seawater desalinization and water quality based on water supply so as to accomplish zero discharge of industry wastewater and circular economy based on the inner and outer situation and the operation experience of zero discharge of industry wastewater in Shougang Iron & Steel Corporation.

In this paper;the ways to solve the water crisis are brief introduced Theadvantageofseawater desalination technology and its different method sare also present:The sea water desalination technologies are compared in terms of capacity,energy consumption,pretreatment requirement,product water quality, landoccupationetc.

It may be the effective compensation way to consider sea water desalination for resolution.
