【 摘 要 】

In this paper, a biological surfactant composed of sophorolipid and rhamnolipid is used as an enhanced ultrafiltration treatment for simulated aniline wastewater and the impact of the surfactant concentration, feed liquid aniline concentration, surfactant compound ratio, solution pH value and operating pressure on the aniline rejection rate and permeation flux is analyzed. The research results showed that the biological surfactant compound was able to remove aniline. The removal effect of aniline was considerable when the aniline concentration was 150 mg/L, the surfactant concentration was 0.8 mmol/L and the surfactant compound ratio was 0.1. The pH value had a significant impact on the aniline rejection rate. However, the operating pressure had little impact on the aniline rejection rate, although it exerted a considerable influence on the permeation flux.
