- Abstract:
- Since the second phase expansion project of an electronic panel enterprise is near the Taihu Lake basin, it is necessary to realize zero discharge of nitrogen and phosphorus from organic wastewater according to the environmental impact assessment requirements. Based on the wastewater quality characteristics, the process of AO biochemical treatment, MBR advanced treatment, reverse osmosis membrane concentration and evaporative crystallization is determined. The project achieves 100% recycling of the wastewater. At the same time, the remaining pollutants are eventually separated in the form of solid waste and sent out for disposal. Practice shows that the selected process route is reasonable, and the project operates steadily with considerable economic and environmental benefits.
