High concentration organic wastewater has the following characteristics: first, the high concentration of organic matter. COD generally more than 2000mg/L, and some even tens of thousands or even hundreds of thousands of mg/L, relatively speaking, BOD is low, a lot of wastewater BOD and COD ratio is less than 0.3. Two is the composition of complex, containing toxic substances in wastewater organic compounds with aromatic compounds and heterocyclic compounds in the majority, but also contain sulfide, nitride, heavy metals and toxic organic compounds. Three is a high color, smell. Some of the waste water gives off a pungent odor, causing adverse effects on the environment. Four is a strong acid strong alkaline.
 

   Usually Fenton, micro electrolysis, activated carbon and resin adsorption process for wastewater pretreatment to improve the biodegradability of wastewater, followed by USAB or IC reactor and anaerobic means to reduce the content of COD in wastewater. Our company will be based on the actual situation of the owners of the corresponding process design.
