摘要
With prior-art biofilm treatment methods involving the use of microorganism carriers, the microorganism carrier filter beds get blocked as the biofilms grow, highly concentrated organic wastewaters, oily/fatty wastewaters, etc. cannot be stably treated, the appreciable costs incurred in dehydrating, drying, and incinerating the reduced-volume sludge of the generated excess sludge, treating the incineration ash, etc., are further increased, compounding the financial considerations relating to various spheres of operation. A wastewater treatment carrier comprises a core portion and a microorganism holding portion, wherein the microorganism holding portion is formed with multi-threads characterizing in that the fibers of the multi-threads are formed in a relaxed state so that the fibers can be spaced apart from each other in the wastewater with forming in multiple stages and a loop. The invention can also be adapted to high-concentration organic wastewater and/or inflowing raw water having high load variability. The invention is also suitable for improving existing aerobic treatment tanks, and allows excess sludge and/or odor generation to be minimized. Moreover, the invention can be stably preserved for extended periods of time with a simple maintenance operation, and can yield stable treatment water quality.
