Abstract
PURPOSE: To remove phosphorus and ammonia nitrogen effectively by subjecting the sewage contg. a small amt. of org. materials and contg. phosphorus and ammonia nitrogen beforehand to a flocculating and separating treatment then to a biological membrane treatment thereby performing nitrification and denitrification.
CONSTITUTION: Sewage such as secondarily treated water of sewage and night soil or others contg. less org. materials and contg. phosphorus and ammonia nitrogen is beforehand subjected to a flocculating and separating treatment, whereby the concn. of phosphorus is reduced. This is subjected to nitrification and denitrification of ammonia nitrogen by an aerobic biological membrane treatment; at the same time, the remaining phosphorus is also removed biologically. As said biological membrane treatment, there are a granular medium living membrane method, a rotary disc method, a trickling filter method, etc., of which a stationary bed type biological membrane treatment using granular media is advantageous because it accomplishes the biological membrane treatment and filtration simultaneously. Plastics, sand, etc. are usable as the media.
