Case

Time: July 2018

 

Treatment capacity: 10t / h * 2 sets.

 

Main pollutants: o-dichlorobenzene (30 / 1), chlorobenzene, o-nitrochlorobenzene (20 / 5) & p-nitrochlorobenzene (30 / 5), m-nitrochlorobenzene.

 

Technical difficulty: the concentration of chlorobenzene raw water is 30mg / L, exceeding the standard by 30 times, the on-site treatment cycle is short, and there is no sludge treatment system

 

Treatment process: sand filtration + blow off + ozone oxidation + activated carbon adsorption

 

Process characteristics: the system has strong pertinence and no sludge is produced in the treatment process, which reduces the treatment cost of hazardous waste. According to the change of the concentration of sewage in the system, the gas production of ozone generator can be adjusted to reduce the operation power and operation cost.
