| dc.description.abstract | In this study, the Microtox@, daphnia and carp and other biological toxicity testing methods, to investigate the strength of the biological toxicity with a panel plant process wastewater at the wastewater treatment unit before and after, another reference to the EPA and the Science Park organism acute toxicity studies, TN , NH3-N, conductivity, chloride ion and TP five kinds of general water quality testing items and the correlation of biological acute toxicity studies, in order to understand the main factors of the panel plant effluent biological toxicity.
The experimental results show that the number of water samples by Microtox@, Daphnia and carp of different detection methods from TUa value numerical difference is quite generally high, which the value of the daphnia detection method from the carp, followed by, Microtox@ lower, opposite the mill wastewater toxicity to Daphnia more sensitive; just use the Microtox@ judge the panel plant effluent organism acute toxicity may have underestimated the situation, but still up to the effect of early warning. General water quality testing items and biological toxicity of the relevance of the experimental results of this study was high positive correlation of total nitrogen and ammonia, and therefore follow-up to investigate the sources of research and plant nitrogen-containing wastewater and the reduction of possible measures to the assessment and implementation.
