    摘要： 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.

    摘要： A method of measuring concentration of dissolved organic nitrogen in sewage. The method includes: filtering a sewage sample using a filter membrane; measuring the concentrations of total dissolved nitrogen (TDN), ammonia nitrogen (NH4+), and nitric nitrogen (NO3−) in the sewage sample, respectively designated as CTDN(I), CNH4+(I) and CNO3−(I); calculating the ratios of (CNH4+(I)+CNO3−(I))/CTDN(I) and CNO3−(I)/CNH4+(I), and according to the ratios, calculating the concentration of dissolved organic nitrogen (DON) in the sewage sample.

    摘要： A denitrification biofilter device, including: a regulating pool, a reactor body, a water tank, a first doser, a second doser, a backwash pump, a water inlet pump, and a blower. The regulating pool includes a raw water inlet and a water outlet. The reactor body includes a uniform water distributor, a filler layer, a buffer layer, a filter layer, a supporting layer, a filler supporting plate, a backwash water outlet, a treated water outlet, and a backwash water inlet. The treated water outlet and the backwash water inlet are disposed at the bottom of the reactor body and are connected to the water tank via pipes. The filler layer is filled with zeolites having a grain size of between 4 and 8 mm, a density of between 1.9 and 2.6 g/cm3, a porosity greater or equal to 48%, and a specific surface area of between 570 and 670 m2/g.
