The generation of anthropogenic wastes, such as household human feces and kitchen waste, has resulted in a severe environmental impact. Sustainable management approaches to address disposal challenges and harness potential nutrient and energy values are urgently needed. This investigation assessed the anaerobic co-digestion of food waste and black water to identify the biochemical methane potential. The household kitchen waste showed improved performance at a dilution ratio of 50% with biochemical methane potential of 265 mL CH₄/g volatile solid (VS), and that of the black water was 220 mL CH₄/g VS without dilution. This trend indicates their easy biodegradation/digestibility and potential for energy recovery. The kitchen waste equal mix ratio of 50% v/v with the black water had the highest biochemical methane potential of 295.13 mL CH₄/g VS when co-digested. High performance was due to the comparative balance in substrate concentrations that offered robust methanogenic activities without inhibitions. The effluent total chemical oxygen demand reduction of ∼90% and other physicochemical parameters showed that the codigestion treatment (kitchen waste and black water 50:50% v/v) was efficient. The codigestion route could offer a decentralized wastewater management system for energy recovery.

家庭黑水与厨房垃圾的共同消化，以实现可持续的分散式垃圾管理：生化甲烷潜力和混合比效应

家庭人类粪便和厨房垃圾等人为废物的产生已经导致严重的环境影响。迫切需要可持续管理方法来应对处置挑战并利用潜在的营养和能量价值。该调查评估了食物垃圾和黑水的厌氧共同消化，以确定生化甲烷潜力。家庭厨余在稀释比例为 50% 时表现出改善的性能，生化甲烷潜力为 265 mL CH ₄ /g 挥发性固体（VS），黑水为 220 mL CH ₄/g VS 未稀释。这一趋势表明它们易于生物降解/消化和能量回收的潜力。50% v/v 的餐厨垃圾与黑水等量混合时的生化甲烷潜力最高，为 295.13 mL CH ₄ /g VS。高性能是由于底物浓度的比较平衡提供了强大的产甲烷活性而没有抑制作用。出水总化学需氧量减少约 90% 和其他物理化学参数表明共消化处理（厨房垃圾和黑水 50:50% v/v）是有效的。共消化路线可以为能量回收提供分散的废水管理系统。
