High COD wastewater treatment

High COD wastewater mainly comes from the chemical industry, which takes animportant position in national economy as a traditional industry. However, withthe development of the chemical industry, the ecological environment isseverely blighted. The COD produced in the chemical wastewater has highconcentration, great toxicity and poor biodegradability and cannot reach theexpected result through common treatment processes. 

Common treatment processes include: physic-chemical method, biologicalanaerobic method, and biological method

As the wastewater produced in the production process has high salinity, itshall be desalted first. The cooling water shall be treated by the biochemicalpool and subsequent treatment before discharging. The treated wastewater canreach the level 1 direct discharging requirement of Integrated WastewaterDischarge Standard in Shandong Peninsula Basin or the acceptance requirementsof sewage treatment plant.
