Internal electrolysis of iron and carbon — A/O/carrier biofilm reactor /O process for medical wastewater treatment

Internal electrolysis of iron and carbon process was used to treat the wastewater produced in a medicine material plant. The principle of its pre-processing, process and the main technical process parameters were introduced in this paper. The results of this pilot scale test showed that the BOD₅ /COD_cr was significantly increased, and the wastewater could meet the third national emission standards by following biological method.
