摘要：
From an experimental and theoretical investigation of the continuity of wastewater organic chemical oxygen demand ( COD) and nitrogen (N) compounds along the link connecting the primary settling tank (PST) and anaerobic digester ( AD), it was found that the primary sludge ( PS) characteristics, viz. the biodegradable and unbiodegradable soluble and particulate COD and N component concentrations, need to be calculated from mass balances around the PST so that the organic and N concentrations conform to continuity principles, and the influent unbiodegradable particulate organics determined from response of the activated sludge ( AS) system are also unbiodegradable under AD conditions.
