ABSTRACT China is the largest garlic producer and exporter in the world, and garlic chips is one of the most important export products. More than 20 tons of garlic processing wastewater (GPW) would be generated for producing 1 ton of garlic chips. The strong ant bactericidal effect of GPW made it difficult to be treated with biological process. The characteristics and components of GPW, the antibacterial mechanism of allicin, the GPW treatment processes of biological method, membrane separation, and advanced oxidation as well were evaluated and summarized to provide a reference for improving the existing GPW treatment technology.

Key words garlic chips; garlic processing wastewater; antibacterial activity; microbial community; biological treatment; advanced oxidation
