Benzene hydrogenation industrial waste water optimal treatment system

Technical Field

The utility model relates to a benzene hydrogenation equipment field, specifically speaking, the utility model relates to a benzene hydrogenation industrial waste water optimal treatment system.

Background

In the production of benzene hydrogenation, a large amount of waste water is produced every day, and the waste water is generally purified and discharged after reaching the standard. Along with the increase of national environmental protection treatment strength, the standard of industrial wastewater purification treatment is higher and higher, the investment is larger and larger, and the cost is increased for enterprises. There are two kinds of external drainage of enterprises, one is a rainwater system, and the other is a production wastewater system. Under normal conditions, rainwater can be directly discharged outside, and production water can also be directly discharged outside if normal. The rainwater system and the process water system are both provided with two paths of directions, one path is directly discharged outside, the other path is discharged to the wastewater treatment system, and once any system is polluted, the system is changed to be sent to the wastewater system for treatment. At present, the monitoring of external drainage almost depends on the mode of patrolling by workers, the patrolling effect is lagged, sometimes unqualified wastewater is possibly discharged outside for a long time and then is discovered by patrolling personnel, and great environmental protection hidden dangers exist. Some process water, such as cooling water, condensate, etc., is discharged into a wastewater system, which may be sent to a wastewater treatment system for treatment, increasing wastewater treatment costs.
