摘要：

The percentage removal (R) of human parasitic nematode eggs in waste stabilization ponds can be described by the empirical equation R = 100 [1 - 0.14exp(-0.38-theta)] where theta is the mean hydraulic retention time (d). The lower 95% confidence limit of this equation, R = 100 [1 - 0.41exp(-0.49-theta + 0.0085-theta(2))] is recommended for the design of ponds to meet the WHO microbiological guideline of less-than-or-equal-to one egg per litre for restricted irrigation.
