High concentration, toxic and harmful organic wastewater, which is difficult to biodegrade, is treated by traditional water treatment methods. The COD removal efficiency of some wastewater is very low or even impossible. However, incineration treatment has high energy consumption and is liable to cause secondary pollution. Wet oxidation technology is an advanced wastewater treatment technology which can better deal with this kind of wastewater.

COD is 2000-100000 MG/L, inorganic salt is less than 20%. Salt-containing wastewater with high boiling point can be decomposed by wet process first. After adsorption, the effluent can be reduced to 1000-2000MG/L, and the effluent can be treated by our MVR process.
