you probably have no metallic copper, more like CuCl2 and CuCl....

the acid is definitely no problem, neutralize with anything...

The H2O2 degrades to pure water, the oxygen goes in the air in a matter of 
hours/days.

As we have established before the copper compounds are the problem, 
possibly killing
the bacteria in the wastewater plant.


Best idea in my opinion is neutralize, and then let evaporate without 
danger.

Can lime be used for neutralizing it?
slaked lime like you use for construction i mean.....
