Title:

ORGANIC WASTEWATER BOD TEST DEVICE AND METHOD, AND APPLICATION

Document Type and Number:

WIPO Patent Application WO/2023/207134

Kind Code:

A1

Abstract:

Disclosed in the present invention are an organic wastewater BOD test device and method, and an application. The device comprises a microbial fuel cell reactor comprising an anode chamber, a cathode chamber, and a wire; a cathode material and a cathode electron acceptor are provided in the cathode chamber, and the cathode electron acceptor comprises potassium ferricyanide; an anode material, microorganisms enriched on the anode material and an anode nutrient solution are provided in the anode chamber, and the anode nutrient solution comprises glucose, glutamic acid, a pH buffer system, mineral elements and vitamins; the anode material and the cathode material are both carbon felts; pretreatment steps for the carbon felts comprises: modifying the carbon felts by using strong oxidizing acid, then washing using water, and neutralizing until the washing liquid is neutral, and burning. The device can stably run for months, the measurement data has good reproducibility, and the stability is remarkably superior to that in conventional microbial electrode method and BOD5 assay method.
