Sewage Treatment by the Canal Reactor with Biomembrane
渠式生物接触氧化法处理城市生活污水

This paper studies that utilizing sewage canal (waterway) of city to treat sewage on bases of researching water pollution, hydrological data and topography of the canal. A new canal reactor of bacteria membrane with continuous operation was designed, made and studied in the laboratory. The operation results of the reactor show that the reactor could effectively treat the sewage of city. The average data of continuous operation during 3 months showed that the removal ratios of CODCr and BOD5 were 88% and 95% in the range of CODCr concentration 180 mg.L(-1)-450 mg.L-1 in the inlet, separately. The technology also has the advantage of low capital cost, low operation cost. This will create the condition to apply the way to practical living sewage treatment of canal.
