This work focuses on the evaluation of the electrochemical dewatering of sludge polluted with model hazardous species. To do this, two sludge samples taken from the outlet of the anaerobic digesters of the municipal Wastewater Treatment Facility of Ciudad Real were polluted with herbicide clopyralid (CP) and with antibiotics amoxicillin (AMX) and ampicillin (AMP), respectively. These sludge samples underwent first dewatering by press filtration and then, the dewatering continued by the application of an electrochemically assisted driven process with increasing electric fields (1.0, 2.0 and 3.0 V cm⁻¹). Results demonstrate that the electrochemically-assisted process can help to exhaust the pollutant adsorbed onto the sludge and attain a supplemental removal (up to 15%) of water in both cases. This is a highly important result, because it can help to develop technologies for sludge treatment that avoid the diffusion of hazardous pollution during the land application of the sludge. No reactivity of the pollutants was observed during the tests.

这项工作的重点是评估被模型有害物质污染的污泥的电化学脱水效果。为此，从雷阿尔城市政污水处理厂厌氧消化池出口采集的两个污泥样品分别被除草剂氯吡菌胺（CP）和抗生素阿莫西林（AMX）和氨苄青霉素（AMP）污染。这些污泥样品首先通过压滤进行脱水，然后通过增加电场（1.0、2.0和3.0 V cm ^-1）的电化学辅助驱动工艺继续脱水）。结果表明，在两种情况下，电化学辅助过程都可以帮助排出吸附在污泥上的污染物，并达到补充除水（最多15％）的目的。这是非常重要的结果，因为它可以帮助开发用于污泥处理的技术，从而避免在污泥的土地应用过程中扩散有害污染。在测试过程中未观察到污染物的反应性。
