An empirically developed relationship between biological growth and substrate utitization that is commonly used for biological systems stabilizing organic wastes is: (ds)/(dt)=-a (dL)/(dt)-K\u2083S (1) where S=sludge concentration present (ppm), a=growth-yield coefficient (ppm-VSS/ppm-BOD), L=BOD remaining (ppm), K\u2083=outo-oxidation rate (1/hr). At low concentration of BOD, the BOD removal rate will be expressed by first-order reaction (b-c, Fig.1). BOD removed can be expressed by following relationship (Eckenfelder and McCabe, 1960): (dL)/(dt)=-KL (2) where K=logalithmic BOD removal rate (1/hr). These equation (1) and (2) may be integrated simultaneously to the following result: S=(aKL\u2080)/(K-K\u2083)(e\uff3e\u3008-K\u2083t\u3009-e\uff3e\u3008-Kt\u3009)+S\u2080e\uff3e\u3008-K\u2083t\u3009(3) where L\u2080=initial concenration of BOD\uff08ppm\uff09.S\u2080=initial concentration of sludge (ppm). This equation is tried out if it is fitted to experimental result by using glucose and (glucose+pepton) as substrate. The result is shown in Fig. 2 and 3. It will be seen thatthe inte grated sludge growth curue will be fitted to experimental result, if Lo/So is adeguate.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/27034"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0387-429X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250785"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8\u7d00\u8981. \u5de5\u5b66\u7bc7"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of the Ryukyus.
