Study on the Demonstration of Seawater Desalination

In this study, the marine circular economy mode of marine industries was investigated by using utilization of Tianjin Beijiang Power Plant. Tianjin Beijiang Power Plant, taking the effective and circular utilization of resources as core, depending on the regional industrial advantage, expanding the industrial chain continually and making itself play the leading role, perfectly combines sea water desalination, salt making, salt chemical products, building materials and some other items, thereby making the wastes of by-products of former processes the raw materials of latter processes. In this way, the power plant has found a new road of circular economy characterized by maximum resource utilization, minimum waste discharge and optimal economic benefit. The project meets the 3R rules of circular economy, i.e. "high efficiency, low consumption and low pollution", and its project combining electric power, water and salt is first-ever in China and a typical circular economy project and an ecological project as well, presenting an important demonstration significance and promotion value for the comprehensive development of circular economy.
