Abstract
A biological toxicity test method for evaluating an ecological safety of an advanced oxidation process comprising the following steps: (1) collecting (preparing) a waste water to be determined; (2) collecting the waste water and a tap water after the advanced oxidation process treatment; (3) subjecting Koi (Cyprinus carpio haematopterus) to the water after treatment for exposure to poison; (4) Determining an anti-oxidation enzyme activity of a liver of the Koi after exposure; (5) Data analyzing. By comparing the changes of liver enzyme activities in different water, the present method evaluates the toxicity changes of micro-pollutant containing water before and after treatment, which fills in the gap of the ecological risk assessment for advanced oxidation technology.
