Resin usually refers to the range of softening or melting after being heated. When softened, it has a tendency to flow under the action of external forces. At room temperature, it is solid, semi-solid, and sometimes it can be a liquid organic polymer.
(1) Do a good job in monitoring the chemical oxygen consumption CODMn in the incoming water from the two sources of oil refining.
(2) Strengthen the coagulation and clarification of the clarification tank to improve the efficiency of removing suspended organic matter and gum organic matter in the raw water. The chemical oxygen consumption CODMn of the first-level desalination feed water is controlled at <1 mg / l.
(3) It may be considered to install an organic matter remover filled with waste strong base anion resin before the negative bunk bed.
(4) Resuscitation treatment of anion exchange resin every 6-12 months to avoid further treatment when resin organic contamination is serious.
