养殖废水低温高效处理与资源化方法及生物安全性评价

伴随着全国畜牧养殖业的快速发展，以黑龙江省为代表的东北地区被划分为生猪养殖潜力发展区。受冬季低温影响，普遍存在养殖废水处理效率低、治理水平落后等问题，严重制约了寒区经济、环境和生态的可持续发展。本项目针对养殖废水处理冬季低温抑制显著、厌氧消化和脱氮效率低、抗生素和重金属类污染物去除难度大及生物安全风险不确定等问题，围绕太阳能内源辐射废水加热新原理、生物电化学辅助厌氧消化与脱氮新方法、电化学深度处理去除抗生素和重金属、污泥堆肥资源化及生物安全性评价几个方面开展研究，为开发高效、经济、绿色、安全的寒区养殖废水处理与资源化新方法提供理论依据。项目成果将实现寒区养殖废水处理的提质增效，助力基础科学研究与全面振兴东北老工业基地国家发展战略的紧密衔接，不但具有重要学术和研究价值，而且孕育着重要的技术突破，可作为服务我国寒区生态文明建设的战略科技储备，将产生不可估量的社会效益、环境效益和经济效益。

With rapid development of national animal husbandry, Heilongjiang Province, which is the typical northeast region, has been shortlisted as the potential zone for cattle breeding industry. As a result of negative impact exerted by low temperature, challenges remain in association with low efficiency of wastewater treatment, which greatly limits sustainable development of cold-region economy, environment and ecology. This project will focus on addressing the problems of low-temperature inhibition, poor efficiency of anaerobic digestion and denitrification, low removal of antibiotics and heavy metals, as well as potential bio-safety. The study will be carried out on solar-energy-driven internal radiation heating of wastewater, bioelectrochemically assisted anaerobic digestion and nitrogen removal, electrochemical elimination of antibiotics and heavy metals, composting resource utilization and assessment of bio-safety. The project aims to develop high-efficiency, sustainable, economic and safe manner, process and technology toward close connection between fundamental research and the strategic need for revitalizing the northeast old industrial bases. The achievements will be of significance in terms of both scientific area and technologies, which is expected to produce crucial social, environmental and economic benefits in ecological civilization of cold regions.
