Abstract

Based on results of pilot scale research with source-separated black water (BW) and grey water (GW), a new sanitation concept is proposed. BW and GW are both treated in a UASB (-septic tank) for recovery of CH4 gas. Kitchen waste is added to the anaerobic BW treatment for doubling the biogas production. Post-treatment of the effluent is providing recovery of phosphorus and removal of remaining COD and nitrogen. The total energy saving of the new sanitation concept amounts to 200 MJ/year in comparison with conventional sanitation, moreover 0.14 kg P/p/year and 90 litres of potential reusable water are produced.

摘要

基于对源头分离黑水（BW）和灰水（GW）的中试规模研究结果，提出了一种新的卫生概念。黑水和灰水均在UASB（-化粪池）中进行处理，以回收甲烷气体。将厨余垃圾添加到厌氧黑水的处理过程中，可使沼气产量翻倍。对出水进行后处理，以回收磷并去除剩余的化学需氧量（COD）和氮。与传统卫生设施相比，新卫生概念的总节能达到每年200兆焦耳，此外，每年还可产生每人0.14千克磷以及90升潜在的可重复利用水。
