摘　　要：传统污水处理工艺以能消能 ,消耗大量有机碳源 ,剩余污泥产量大 ,同时释放较多CO2(因耗能 )到大气之中。当今 ,全球普遍强调的可持续发展经济模式在污水处理领域也得到体现。因此 ,研发以节省能 (资 )源消耗、并最大程度回收 (用 )有用能 (资 )源的可持续污水处理工艺已势在必行 ,在详细介绍两种新近在欧洲出现的可持续处理工艺———反硝化除磷、厌氧氨 (氮 )氧化的基础上 ,提出一个以转换有机能源 (甲烷 )、回收磷酸盐 (鸟粪石 )、回用处理水 (非饮用目的 )Conventional sewage treatment processes destroy energy with energy, consume lots of organic carbon, produce much excess sludge and release much CO 2 into atmosphere. Nowadays, the sustainable economic development way emphasized in the world also reflects the field of wastewater treatment. Therefore, it is essential to develop the processes with less consumption of energy and resources and with more recoveries of useful energy and resources from sewage. Based on denitrifying dephosphatation and anaerobic ammonium oxidation (ANAMMOX) which were recently developed in Europe, a sustainable biological nutrient removal (BNR) process is proposed in this article, with the aims of conversion of organic energy (into methane), recovery of phosphates (as struvite), reuse of effluent (for non drinking cases).
