To obtain a kind of highly active, robust, inexpensive anode for electrocatalytic oxidizing wastewater, perovskites Sr_xLa_1-xMn_yCo_1-yO_3-δ (SLMCOxy) were prepared by doping Mn at B-Site and Sr at A-Site into the LaCoO₃ matrix to form oxygen vacancies, inducing more production of reactive oxidized substance. Then the perovskites mixed with binder and conductive agent were coated on titanium plate as alternative anodes Ti/SLMCOxy, which were applied for cleaning simulated wastewater composed of 200 mg L⁻¹ ammonium nitrogen (AN) and 20 mg L⁻¹ methyl orange (MO) to confirm the optimum doping amount of Sr and Mn and operation conditions like temperature, current density, pH and the concentration of chloride. The highest removal ratio up to 98.23% for AN, 99.61% for MO, 88.16% for COD and current efficiency up to 86.47% were achieved respectively with the contribution of OH, O₂⁻ and active chlorine, and the removal ratio of AN and MO can keep above 95% after 5-time’s reusing the anode. Moreover, the anode performed good degradation effect for landfill leachate with 96.12% of AN and 85.43% of COD removed at energy consumption of 26.88 kWh (Kg COD)⁻¹. Therefore, this original anode Ti/SLMCOxy would be a promising candidate for effective organic wastewater treatment.

为了获得一种用于电催化氧化废水的高活性，坚固，廉价的阳极，通过在B站点掺杂Mn和在A站点掺杂Sr，制备了钙钛矿Sr _x La _1-x Mn _y Co _1-y O3 _-δ（SLMCOxy）。 -在LaCoO ₃基质中形成氧空位，诱导更多的反应性氧化物质产生。然后将混合有粘合剂和导电剂的钙钛矿作为替代阳极Ti / SLMCOxy涂在钛板上，用于清洗由200 mg L ^-1铵态氮（AN）和20 mg L ^-1组成的模拟废水甲基橙（MO），以确认Sr和Mn的最佳掺杂量以及操作条件，例如温度，电流密度，pH和氯化物浓度。最高去除率高达98.23％为AN，用于MO 99.61％，88.16％的COD和电流效率高达86.47％用的贡献分别达到OH，ö ₂ ^-和活性氯，和AN的去除率和5次重复使用阳极后，MO可以保持95％以上。此外，阳极以26.88 kWh（Kg COD）^-1的能耗去除了96.12％的AN和85.43％的COD，对垃圾渗滤液具有良好的降解效果。因此，这种原始的阳极Ti / SLMCOxy将成为有效处理有机废水的有希望的候选者。
