The purpose of this study was to evaluate the potential of a pilot membrane bioreactor (MBR) to treat effluents from a fruit processing factory, for the removal of pesticides, on its own, and combined with other treatment technologies. The stability of the MBR was monitored by the parameters chemical oxygen demand (COD), pH, total suspended solids (TSS) and permeability. The addition of pesticides was established to generate concentrations of 20 μg.L⁻¹ for 2,4-D, carbendazim and diuron, and 1.5 μg.L⁻¹ for atrazine in the bioreactor. The removal of pesticides by the MBR was evaluated by two experiments with variations in HDT (20 and 25 h) and operation of post-treatments with either activated carbon (AC), reverse osmosis (RO) or ozonation (O₃). The MBR demonstrated robustness and stability in maintaining the quality of the permeate even under high variations of COD and biomass content. However, the removal of the pesticides was only partial. Among the hybrid systems, comprising a combination of the MBR and a post-treatment, the MBR/AC and MBR/RO presented excellent results, proving to be efficient for pesticides removal. The MBR/O₃ system, however, did not perform as well as the others, which can be explained by the low ozone doses applied.

这项研究的目的是评估中试膜生物反应器（MBR）自行处理水果加工厂的废水，去除农药的潜力以及与其他处理技术结合的潜力。MBR的稳定性由化学需氧量（COD），pH，总悬浮固体（TSS）和渗透性参数来监控。成立农药的添加，以产生20μg.L浓度^-1 2,4- d，多菌灵和敌草隆，和1.5μg.L ^-1为在生物反应器莠去津。MBR去除农药的方法是通过两个实验进行的，该实验具有HDT的变化（20和25 h）以及使用活性炭（AC），反渗透（RO）或臭氧化（O ₃）进行后处理的操作）。即使在COD和生物质含量变化很大的情况下，MBR仍能保持渗透物质量的鲁棒性和稳定性。但是，农药的去除只是部分的。在混合系统中，包括MBR和后处理的组合，MBR / AC和MBR / RO表现出优异的效果，证明对农药去除有效。但是，MBR / O ₃系统的性能不如其他系统，这可以通过使用低臭氧剂量来解释。
