A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.

介绍了一种新的连续处理拜耳法氧化铝生产废液的低能耗光催化工艺。这项新技术每天可以处理多达1500升的工业苛性碱废水，减少二氧化碳的排放。经过光处理的炼油厂废水还可节约30%的用水。
