Abstract
A system including units of anoxic, anaerobic and aerobic has been developed
in this study to remove nutrients for swine wastewater. Three tests at different
organic loading rates were also conducted to evaluate the treatment efficiency for
this system.
Both anoxic and anaerobic units were controlled at 37±1 ℃, while the aerobic
unit was controlled at 30±1 ℃. The influent COD was prepared at a concentration
about 5,000 mg/L before feeding. Three different sets of tests at system HRT of 5.75
d, 3.83 d and 2.875 d were operated to evaluate the performance of the whole system
and each individual unit. Water quality including solids, organic matters, nitrogen
and phosphate were monitored during experiment.Experimental results showed that all three tests had significant effect in
removing both COD and nutrients for swine wastewater. The removal efficiencies
of COD, total nitrogen and total phosphate were achieved at the ranges of 92~98%,
62~93% and 42~88%, respectively.
