Some sewage will be produced in the process of imidazole production, which can only be discharged outside after certain treatment. The process of sewage treatment is like this. First, there must be a sewage treatment tank. First, the sewage is discharged into the sewage treatment tank. After a certain time of chemical reaction, the raw materials used to produce imidazole will react with each other, and some harmful substances will disappear after these reactions. After certain sedimentation, some solid substances in it will sink to the bottom of the pool, and we can clean up these solid substances, so that the water will be much clearer. After some reaction treatment, clean water containing a small amount of chemicals is generated. These clean water can be treated to remove harmful substances. Now the environmental protection department has requirements for the water discharged by imidazole manufacturers, so all manufacturers should buy complete sets of environmental protection equipment.
