Abstract:

The technological process of the groundwater pre-desalination system of Shaanxi Weihe Coal Chemical Engineering Group，as well as the technical and equipment problems occurred in the process of debugging and running，is introduced. Meanwhile，in the reverse osmosis system，the effects of electrical conductivity，influent SDI，influent residual chlorine and ORP，security filter，produced water backpressure，etc. on the system are analyzed and discussed，and corresponding countermeasures are put forward.

Key words: reverse osmosis, debugging and running, desalination
