Study on Application of Two-stage Bio-contact Oxidation Technology in Municipal Wastewater Treatment in Alpine Region
ICICTA), 2011 International Conference(2011)
Abstract
Following the introduction of characteristic of wastewater and correlated project in the Alpine Region, the problems were pointed out which should be noticed in wastewater treatment process selection in this specific area. Some suggestions about key design parameters were proposed, and the Two-stage Bio-contact Oxidation Technology was been selected and applied in wastewater treatment plant in north suburb of Dongsheng District, Erdos City. Through project application, it was indicated that when average value of COD, BOD5 and SS was 483.2 mg/L, 244.4 mg/L and 258.4 mg/L respectively during 10 days at about 12°C in influent wastewater, average value in effluent water reached up to 57.1 mg/L, 23.8 mg/L and 26.5 mg/L and removal rate of each contaminant was up to 88.2%, 90.3% and 89.7% respectively. It gained preferable results and this successful project also provided references for other similar wastewater treatment plant for future.
