Pressure swing adsorption nitrogen production equipment is based on its adsorbent (carbon molecular sieve) under different pressure adsorption capacity changes to obtain nitrogen equipment. Under a certain pressure, when air passes through the screening bed, the expansion rate of oxygen on the surface of the carbon molecular sieve is much higher than that of nitrogen, so that oxygen molecules are adsorbed by the carbon molecular sieve, and nitrogen molecules can aggregate.
A large amount of lye is produced in the industrial production process. The cod value in the lye is high. If the lye is not treated in time, it will be difficult to operate the biochemical treatment tank in the sewage treatment process. At the same time, the waste lye contains a large amount of odorous substances and is easy to be polluted. serious. Therefore, when waste lye is produced, the waste lye must be treated in time.
