In this work, three advanced oxidation technologies have been studied to improve the quality of the effluents of a physicochemical process and of a combined physicochemical-biological process during the treatment of actual industrial wastes of wooden door-manufacturing factories. From the treatment point of view (neglecting costs), advanced oxidation processes can be successfully used to treat both, coagulated and biologically treated wastes. Conductive-diamond electrochemical oxidation (CDEO) was found to be the more effective technology because it can reduce completely the chemical oxygen demand (COD) (no production of refractory compounds) with a very high current efficiency. However, from the economic viewpoint, the direct treatment of the coagulated wastes can not be recommended because it is very expensive. Only Fenton oxidation or conductive-diamond electrochemical oxidation can be cost-efficiently used to refine the quality of the effluent of the biological process.
在这项工作中，研究了三种高级氧化技术，以改善在处理木门制造厂实际工业废物过程中物理化学工艺以及物理化学 - 生物联合工艺的出水水质。从处理角度来看（忽略成本），高级氧化工艺可成功用于处理经过混凝和生物处理的废物。发现导电金刚石电化学氧化（CDEO）是更有效的技术，因为它能以非常高的电流效率完全降低化学需氧量（COD）（不产生难降解化合物）。然而，从经济角度来看，不建议直接处理混凝后的废物，因为成本非常高。只有芬顿氧化或导电金刚石电化学氧化可经济高效地用于改善生物工艺出水的质量。
