The microplastics removal and its effects on membrane fouling in membrane bioreactor (MBR) for treating polluted surface water in drinking purpose was investigated in this study. Typical microplastics polyvinylchloride (PVC) with concentration 10 particles/L was added in the feed water. MBR was effective in treating organic matters and ammonia with removal rate over 80% and 95%, respectively. The removal performance was immediately inhibited with the microplastics PVC added into the MBR system, and recovered after operated for few days. The membrane fouling and cleaning results indicated that microplastics contamination could led to higher membrane fouling, and also the irreversible membrane fouling. The main contributor of rejection is the membrane module and the adsorption onto bio-carrier. The microbial community of the system before and after PVC addition did not show obvious difference. MBR has the potential to be used as effective technology in treating microplastics contaminated polluted surface water.
本研究考察了膜生物反应器（MBR）中微塑料的去除及其对处理受污染地表水的膜污染的影响。在原水中添加了浓度为 10 个/L 的典型微塑料聚氯乙烯（PVC）。MBR 有效地处理了有机物和氨，去除率分别超过 80%和 95%。当将微塑料 PVC 添加到 MBR 系统中时，去除性能立即受到抑制，但经过几天的运行后得到恢复。膜污染和清洗结果表明，微塑料污染会导致更高的膜污染和不可逆转的膜污染。截留的主要贡献者是膜组件和生物载体的吸附。添加 PVC 前后系统的微生物群落没有明显差异。MBR 有潜力成为处理受微塑料污染的受污染地表水的有效技术。
