本发明公开了一种利用微生物燃料电池对废水厌氧生物降解度快速判断的方法，包括以下步骤：采取方形双室反应器，反应器阳极槽内加入待测废水、经驯化后的厌氧污泥和阳极电极，调节pH至7～9并持续曝入氮气至少5min，封盖保持厌氧状态；负极槽内加入酸性高锰酸钾溶液和负极电极；外部电路连接含染料废水电解设备及配套比色卡。该装置持续反应至少48h后，含染料废水电解设备中液体颜色与比色卡比对，匹配颜色的对应数值越高则废水厌氧生物降解度越好。本方法操作简便，具有耗时短且有较好的普适度的优点。 The invention discloses a method for rapidly judging anaerobic biodegradation degree of wastewater by using a microbial fuel cell. The method comprises the following steps of: using a square two-chamber reactor; adding to-be-detected wastewater, acclimatized anaerobic sludge, and an anode electrode in a reactor anode groove, adjusting the pH value to 7-9, continuously adding nitrogen for at least5 min, and keeping the cover in an anaerobic state; adding an acidic potassium permanganate solution and a negative electrode into a cathode groove; connecting an external circuit with a dye-containing wastewater electrolysis device and a matched color card; and matching the color of the liquid in the dye-containing wastewater electrolysis device with the colorimetric card after the
