A combination of thermophilic aerobic membrane reactor (TAMR) and conventional activated sludge (CAS) was studied by means of two pilot plants at semi-industrial scale in order to simulate the new configuration adopted in a full-scale facility for the treatment of high strength aqueous wastes. Aqueous wastes with high contents of organic pollutants were treated by means of the TAMR technology, progressively increasing the organic load (3-12 kg m d). A mixture of municipal wastewater and thermophilic permeate was fed to the CAS plant. The main results are the following: achievement of a high COD removal yield by both the TAMR (78%) and the CAS (85%) plants; ammonification of the organic nitrogen under thermophilic conditions and subsequent mesophilic nitrification; capacity of the downstream mesophilic process to complete the degradation of the organic matter partially obtained by the TAMR process and precipitation of phosphorus as vivianite and carbonatehydroxylapatite in the TAMR plant.
采用两个中试规模的嗜热好氧膜生物反应器（TAMR）和传统活性污泥（CAS）组合工艺，模拟在处理高强度水性废物的全规模设施中采用的新型配置。采用 TAMR 技术处理高浓度有机污染物的水性废物，逐步增加有机负荷（3-12kgm d）。将城市污水和嗜热渗透液的混合物输送至 CAS 厂。主要结果如下：TAMR（78%）和 CAS（85%）工厂均实现了高 COD 去除率；在嗜热条件下对有机氮进行氨化，随后进行中温硝化；下游中温工艺能够完成 TAMR 工艺部分获得的有机物的降解，并在 TAMR 工厂中将磷沉淀为蓝铁矿和碳酸羟基磷灰石。
