摘要： The present invention provides a method for detecting biochemical oxygen demand. Active sludge, surface water, domestic waste water, or industrial waste water comprising microorganism is taken as a water sample with microorganism in the method provided by the present invention. The water sample with microorganism is cultivated to obtain a microorganism film. The blank water sample and the target water sample are made to pass through the microorganism film respectively. The dissolved oxygen reduction current values of the blank water sample and the target water sample are detected. The difference value between the dissolved oxygen reduction current value of the target water sample and that of the blank water sample is obtained. On the basis of the difference value and the predetermined standard curve, the biochemical oxygen demand of the target water sample is acquired. The method provided by the present invention adopts active sludge, surface water, domestic waste water, or industrial waste water comprising microorganism as the water sample with microorganism. The environmental adaptability of the prepared microorganism film is strong, so that one or more of tap water, well water, atmospheric water, or ground water may serve as medium to maintain the physiological activity with no need of providing a buffer solution system.
摘要翻译：本发明提供一种检测生化需氧量的方法。以本发明提供的方法将活性污泥，地表水，生活废水或包含微生物的工业废水作为具有微生物的水样。培养含微生物的水样，得到微生物膜。使空白水样和目标水样分别通过微生物膜。检测空白水样和目标水样的溶解氧还原电流值。获得目标水样品的溶解氧还原电流值与空白样品的溶解氧还原电流值之间的差值。根据差值和预定标准曲线，获得目标水样的生化需氧量。本发明提供的方法采用活性污泥，地表水，生活废水，微生物作为水样的微生物工业废水。所制备的微生物膜的环境适应性强，使得自来水，井水，大气水或地下水中的一种或多种可以用作培养基以维持生理活性，而不需要提供缓冲溶液体系。
