摘要

The study was aimed to solve the problem of high level in turbidity, bad smell and taste leading in negative influence on the river landscape, which were caused by the high level of suspended substance, nitrogen and phosphorus in parts of urban rivers where the recycled water was used as water resource. The field test research focused on purifying polluted water in Kun Yu River by the biological contact oxidation process (BCOP) in Beijing. The rate of the flow in the pilot test was designed to 32m3/d, while the hydraulic retention time (HRT) was 5h. The results showed that the test system had good removal efficiency in turbidity which reached to 70.0% of the mean removal rate and the turbidity of effluent is steady during the six months of operation. The results of particle size analysis showed that the system also had high removal efficiency in large-diameter particles in river and the particles larger than 1000 microns were completely removed in the outflow of the channel simulator. Meanwhile, the system of BCOP utilized could effectively reduce the organic matter and nutrients in the channel simulator. The mean removal rate of CODCr, BOD5, Ammonia nitrogen, TN and TP were 61.48%, 69.64%, 71.70%, 30.77%, and 41.79% respectively.
