摘要:- 某電子面板二期擴(kuò)建項(xiàng)目靠近太湖流域，根據(jù)環(huán)評(píng)要求，需實(shí)現(xiàn)有機(jī)廢水氮、磷“零排放”。根據(jù)廢水水質(zhì)特點(diǎn)，確定采用AO生化+MBR深度處理+反滲透膜濃縮+蒸發(fā)結(jié)晶處理工藝。項(xiàng)目實(shí)施后，實(shí)現(xiàn)了廢水100%的回收利用，同時(shí)其余污染物最終以固廢形式析出并外運(yùn)處置。實(shí)踐表明，該工藝路線選擇合理，系統(tǒng)運(yùn)行穩(wěn)定，具有可觀的經(jīng)濟(jì)效益及環(huán)境效益。
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.
