摘　　要：针对化工废水无差别的接管导致污水厂生化系统无法高效运行的问题,本文以实际化工废水为对象,提出了一种基于好氧污泥呼吸速率(OUR)的STOD值法(STOD=OUR废水/OUR内源)评价化工废水水质。此方法可将废水水质分别为可生化、难降解、有毒三种类别,对高浓度、低浓度废水水质的评价均快速、准确。利用STOD、发光细菌、斑马鱼、大型溞评价废水水质,正确率分别为100%、50%、62.5%、37.5%,STOD值更能科学合理地评价废水水质。从而,本文提出了一套废水水质分类接管模型,实现了接管生化系统高效、经济运行以及难降解、有毒物质切实消减。Aiming at the problem that no difference pipe connection measures cause biochemical system cannot run efficiently in the chemical industry wastewater treatment plant,this study focuses on the subject of the actual chemical wastewater.Put forward a method of STOD value based on active sludge oxygen uptake rate(OUR)to evaluate chemical wastewater quality,by this method,wastewater quality can be respectively to three categories of biochemistry,refractory,poisonous fast and accurately.Using STOD,luminous bacteria,zebrafish,daphnia magna to evaluate wastewater quality,the correct rates were 100%,50%,62.5% and 37.5% respectively,STOD value can evaluate wastewater quality more scientifically and reasonably.Thus,a set of classified pipe connection model of wastewater quality is put forward,which realizes the efficient and economic operation of biochemical system of pipe connection,as well as the effective reduction of refractory and toxic substances.
