摘　　要：污水处理厂协同处理餐厨垃圾是行业内研究热点,但目前对不同协同处理方式的比较较少。通过污水处理模型模拟的方法,研究餐厨垃圾投加至污水进水和投加至污泥厌氧消化池2种策略下对厌氧消化产能、污泥产量、污水处理和能量平衡的影响。研究结果表明,污水处理厂宜通过厌氧消化池协同处理餐厨垃圾,从而可获得更高的能量回收率。The collaborative treatment of kitchen waste by sewage treatment plant is a research hotspot in the industry,but there are few different collaborative treatment methods at present.Through the method of sewage treatment model simulation,the effects of two strategies of adding kitchen waste to sewage inlet & sludge anaerobic digestion tank on anaerobic digestion capacity,sludge output,sewage treatment &energy balance are studied.The results show that the sewage treatment plant should treat kitchen waste through anaerobic digestion tank,so as to obtain higher energy recovery rate.
