Personal care product (PCP) industry liquid wastes contain shampoo residues, which are usually treated by aerobic activated sludge (AS). Unfortunately, AS is expensive for PCP wastes because of high aeration and energy demands, whereas potentially energy-positive anaerobic designs cannot meet effluent targets. Therefore, combined anaerobic-aerobic systems may be the best solution. Seven treatment systems were assessed in terms of energy and treatment performance for shampoo wastes, including one aerobic, three anaerobic (HUASB, AHR and AnCSTR) and three anaerobic-aerobic reactor designs. COD removals were highest in the HUASB-aerobic (87.9 ± 0.4%) and AHR-aerobic (86.8±0.5%) systems, which used 69.2% and 62.5% less energy than aerobic AS. However, actual methane production rates were low relative to theoretical in the UASB and AHR units (∼10% methane/COD removed) compared with the AnCSTR unit (∼70%). Anaerobic-aerobic sequence reactors show promise for treating shampoo wastes, but optimal designs depend upon whether methane production or COD removal is most important to operations.
个人护理产品（PCP）行业的液体废物含有洗发水残留物，通常采用好氧活性污泥（AS）进行处理。然而，由于高曝气和能源需求，AS 对于 PCP 废物来说成本高昂，而潜在的能源积极的厌氧设计无法达到排放标准。因此，组合厌氧-好氧系统可能是最佳解决方案。本研究评估了七种处理洗发水废物的处理系统在能源和处理性能方面的表现，包括一个好氧系统、三个厌氧系统（HUASB、AHR 和 AnCSTR）和三个厌氧-好氧反应器设计。在 HUASB-好氧（87.9±0.4%）和 AHR-好氧（86.8±0.5%）系统中，COD 去除率最高，比好氧 AS 分别节省了 69.2%和 62.5%的能源。然而，与 AnCSTR 相比，UASB 和 AHR 单元中实际的甲烷产生速率相对较低（∼10%甲烷/COD 去除）（∼70%）。厌氧-好氧序列反应器在处理洗发水废物方面具有潜力，但最佳设计取决于甲烷产生或 COD 去除对操作的重要性。
