摘要: Controlled water use is an important component of sustainable fresh-cut vegetable production because limited resources, and also for controlling the quality wastewater re-used in processing or irrigating on fields. In our study consumption plants varied from 1.5 to 5.0 m 3 t -1 finished product. one plant, monitored over three years, almost 90% was used washing rinsing vegetables, but more than organic load generated stage. The results including microbial wastewaters showed that should be treated before re-use. Separate treating stage recommended. Pre-treatment using precipitation chemicals sedimentation basins decreased total solids water, allowing further treatment waters.
