The prototype system of integrated anaerobic filter with condenser of air conditioner (anaerobic filter-condenser; ANCO) was developed for sustainable water-energy management model in green office building. The ANCO consists of an insulated anaerobic filter (IAF) and condenser that are connected to an existing refrigerant of air conditioner. The system applied waste heat energy from an air conditioner to improve wastewater treatment efficiency. While the performance of air conditioner also could be enhanced by decreasing refrigerant temperature from transferring waste heat through the IAF system for increasing wastewater temperature. The waste heat from air conditioner could stimulate higher microbial activity in the IAF and at the same time, this could increase air conditioner performance. From the overall results, it was found that with wastewater flow rate 180 liter/day, the ANCO prototype could recycle waste heat approximately 2.82 kWh/day. The waste heat transferred into wastewater could increase water temperature up to averagely 35.4 °C. The system performance for removal of suspended solids (SS) and COD were averagely 49.9% and 49.3%, respectively. The coefficient of performance (COP) of air conditioner was increased by 30.25% and electric consumption was decreased by 22.96%. The ANCO system could save electrical energy averagely 2.62 kWh/day. Then, the ANCO system can decrease heat into environment and decrease greenhouse gas emission 602 kgCOeq/year. Therefore, the ANCO system was pronounced to be the prototype eco-friendly onsite-wastewater treatment system for green office building application.
开发了一种带有空调冷凝器的集成厌氧滤池(anaerobic filter-condenser;ANCO)原型系统,用于绿色办公建筑的可持续水-能源管理模型。ANCO 由一个隔热厌氧滤池(IAF)和冷凝器组成,与现有的空调制冷剂相连。该系统应用空调废热来提高废水处理效率。同时,通过从 IAF 系统中传递废热来降低制冷剂温度,从而提高废水温度,可以增强空调的性能。空调的废热可以刺激 IAF 中更高的微生物活性,同时也可以提高空调的性能。从总体结果来看,发现以 180 升/天的废水流量,ANCO 原型每天可回收约 2.82 kWh 的废热。传递到废水中的废热可将水温提高到平均 35.4°C。悬浮固体(SS)和 COD 的去除率分别平均为 49.9%和 49.3%。空调的性能系数(COP)提高了 30.25%,耗电量降低了 22.96%。ANCO 系统平均每天可节约 2.62 kWh 的电能。然后,ANCO 系统可以减少向环境中排放的热量和温室气体排放 602 kgCOeq/年。因此,ANCO 系统被宣布为绿色办公建筑应用的原型环保现场废水处理系统。
