Abstract：

The reverse osmosis system of a large coal chemical wastewater zero discharge system is introduced. The water source of the project is the effluent from the sewage treatment facilities of the whole plant. After concentration and reduction by reverse osmosis technology, it enters into evaporation crystallization for crystallization treatment, so as to realize zero discharge of the whole plant. However, in actual operation, a series of common problems of reverse osmosis system appear in the reverse osmosis system of the project. This paper analyzes the main problems one by one, and puts forward the supporting solutions. The relevant ideas can be used for reference in the design and improvement of membrane treatment process.
Key words: reverse osmosis; reclaimed water reuse; high salt water; zero discharge.
