| 内容記述 | In order to develop and establish an inexpensive and efficient waste water treatment device for small-scale manufacturing factories with waste water treatment capacity of 50m^3 /day, the Ryukyu Limestone was tested as a medium for filtration treatment. 1. Characteristics of biological filters The following restults were obtained from analysis of physical properties of the Ryukyu Limestone and biological adhesion experiment: (1) The limestone samples investigated as potential media were Motobu(F), Makiminato(A), Naha(B,C), Yomitan(D,E), and reef coral(G,H,I,). Limestone F, the oldest one in Okinawa is the Paleozoic origine. A,B,C and D are limestones classified as the Ryukyu Limestone originated in the Quaternary formation. These limestones are so abundant that they are easily available throughout Okinawa. The physical properties of the Ryukyu Limestone and reef coral tested are grouped into two, the soft limestones and the hard ones. All of them are porous in a considerable degree, excepting the hardest Motobu limestone, which has fine crystalline character. (2) A degree of adhesion of microorganisms were generally proportional to water absorption capacity. The Ryuku Limestone, having higher water absorption capacity, showed desirable adhesion of microorganisms. (3) Makiminato limestone(awa-ishi), Yomitan limestone(coral), Naha limestone(travatine), and reef corals were considered as useful biological filters. 2. Small-scale filtration treatment experiment The following results were obtained from a small-scale experiment of Makiminato limestone, Yomitan limestone, reef coral, and plastic material as biological filters with artificial sewage water: (1) Limestone filters showed more effective biological adhesion than those of plastic material. However, no significant differences were observed among the limestones and reef coral. (2) The BOD removal led to the following BOD removal formula under a limited range of concentration of the BOD: Le/Lo=e^<-KADQ^<1-n>.V^<-1.tr>> (3) High efficiency of water treatment was obtained at the level of more than 20 m^3/m^2. day hydraulic loadings. (4) Laboratory experiment showed that in a case of artificial sewage water, the BOD loadings were suitable at the level of 1 kg/m^3• hydraulic loadings. (5) Limestone filters tested showed strong durability and usefulness as biological filters for waste water treatment. 3. Medium-scale experiment The results from the field experiment of factory's waste water treatment are as follows: (1) High efficiency of water treatment was obtained at the level of 0.5kg/ BOD/m^3 day, however, the water treatment efficiency decreased at the level of 1 kg-BOD/m^3. day. (2) Desirable aerobic conditions in the waste water treatment chamber appeared when the BOD loadings were at a level of 0.5kg/m^3. day. But when the BOD loadings reached at a level of 1 kg/m^3. day the chamber turned to show anaerobic conditions. (3) A remarkable increase in the efficiency of water treatment was not obtained by means of forced airation. | |||||||||||||||||||||
