摘　　要：报导了一种用皮状丝孢酵母组成的ＢＯＤ微生物传感器和流通式微机化愉速ＢＯＤ测定仪。本法的响应时间为（３～７）ｍｉｎ，测定范围为（１０～６０）ｍｇ／Ｌ，线性方程ΔＩ＝０．４２＋１．６４Ｃ，相关系数γ＝０．０９７。对４０ｍｇ／ＬＢＯＤ标样平行测定８次的相对标准偏差ＲＤ＝３．７１％，加标回收率为９４．１％～１０４．７％A BOD microbial sensor and the instrument for BOD estimation fast with a circulatory fit and a computer have been developed. The responding time of the method is(3～7)min and the linear ralationship is excellent in the range of BOD(10～60)mg/L and linear equation is ΔΙ=0.42+1.64. The results show that the analytical standard error is not more than 3.71% and the recovery of BOD in standard substance of wast water is 94.1%～104.7%
