An ATP luminescence method was used to determine the toxicity of three reference toxicants to two sources of domestic activated sludge, and an activated sludge from a laboratory model plant. Repeatability in the ATP test was demonstrated for Cr (as K2Cr2O7), Zn (as ZnSO4 x 7H2O), and 3,5-dichlorophenol (3,5-DCP) using each source of activated sludge. The three sources of sludge showed sensitivity to Cr and 3,5-DCP, and insensitivity to Zn using the ATP luminescence method. Sludge source did not appear to effect test response. The toxic response to 3,5-DCP in model and domestic activated sludge was shown to be dependent on sludge solid concentration (measured as total suspended solids, gTSS(-1). It is recommended that a standard solids concentration is used during toxicity evaluation.
采用ATP发光法测定了三种参比毒物对两种生活活性污泥来源以及一种实验室模型工厂活性污泥的毒性。使用每种活性污泥来源,对铬(以重铬酸钾形式)、锌(以七水硫酸锌形式)和3,5 - 二氯苯酚(3,5 - DCP)进行了ATP测试的重复性验证。使用ATP发光法时,三种污泥来源对铬和3,5 - DCP表现出敏感性,对锌不敏感。污泥来源似乎不影响测试响应。模型活性污泥和生活活性污泥对3,5 - DCP的毒性响应显示取决于污泥固体浓度(以总悬浮固体计,gTSS⁻¹)。建议在毒性评估期间使用标准固体浓度。
