3年前,为解决造纸废水污染渭河流域的难题,陕西省科技厅开始组织专家开展技术攻关,由西安交通大学贺延龄教授在西安惠宁造纸厂进行污水零排放示范工程。如今,其研发的“厌氧—好氧生物处理技术”已通过环保部门组织的达标验收,使以废纸为原料的造纸企业实现了废水零排放。
Three years ago, in order to solve the problem of papermaking waste water pollution in the Weihe River Basin, Shaanxi Provincial Science and Technology Department began to organize experts to tackle the technical problems. Professor He Yanling of Xi’an Jiaotong University conducted a demonstration project of zero discharge of waste water at the Huining paper mill in Xi’an. Nowadays, the “Anaerobic-Aerobic Biological Treatment Technology” developed by it has passed the acceptance inspection organized by the environmental protection department, which has enabled the paper-making enterprises using waste paper as raw materials to achieve zero discharge of wastewater.
