Microbial electrolysis cell (mec) reactor and rapid test method for biochemical oxygen demand (bod) of organic wastewater

Abstract

The present disclosure provides a microbial electrolysis cell (MEC) reactor and a rapid test method for a biochemical oxygen demand (BOD) of organic wastewater, and relates to the technical field of analysis and detection. In the present disclosure, an efficient MEC reactor is constructed based on a MEC sensing technology; meanwhile, combined with a continuous short-cycle test method and a supporting data calculation method, a rapid test method is obtained, and can be applied to various types of complex organic wastewater that does not have a biologically toxic substance and is greater than 5 mg BOD/L. After three cycles of test, last two stable cycles are taken to allow calculation; at the same time, a resulting curve is divided into multiple segments according to changes in main components of a degraded organic matter in different periods to allow segmented weighted calculations.
