The utility model relates to a biochemical oxygen demand measuring device stable in detection and easy to clean, which comprises a reaction tank, and the inner wall of the reaction tank is coated with a Teflon coating; an oxygen electrode fixing hole forming a 45-degree angle with the side wall surface is formed in one side wall of the reaction tank, and an oxygen electrode is placed in the oxygen electrode fixing hole; and a liquid level switch interface, an aeration pump interface and the like are also arranged on other side walls of the reaction tank. As a dissolved oxygen electrode needs to be used in the BOD detection process and is in an air-saturated aqueous solution, bubbles are very easy to form in the process to interfere with BOD measurement, according to the biochemical oxygen demand measuring device disclosed by the utility model, the oxygen electrode fixing hole which forms an angle of 45 degrees with the side wall surface is formed in the side wall of the reaction tank, and the oxygen electrode
