摘要
本文探讨了“活水”在治理富营养化水体中的应用价值,包括:天然“活水”在净化城乡污水中的作用,人工“活水”在净化水产养殖污水中的应用和城市“活水”净化黑臭水体的实际效用。提出了应用“活水”治理富营养化污水的设计方案,包括清除沉积污泥,为制造“活水”夯实基础;快速补充氧气,为恢复“活水”确立前提;采用节能技术,制造廉价“活水”净化污水;借助微生物运用,提升水体生态“活性”等。从而证明了建立或修复以好氧有益菌为核心的水体生态系统,打造或维持多向循环流动的“活水”状态和生态与人工结合全方位、全时段持续供给充足溶解氧,形成具有旺盛生命活力和强大净化能力的“活水”生态系统的方法,是治理城乡富营养化水体的可持续途径。
The application value of“living water”in eutrophic water treatment was analyzed,including the role of natural“living water”in urban and rural sewage purification,the application of artificial"living water"in aquaculture sewage purification,and the actual effect of urban“living water”in black and odorous water purification.A systematic scheme for treating eutrophic wastewater by using“living water”was proposed,including removing the silt at the bottom of the water body,consolidating the foundation of“living water”,providing oxygen quickly,establishing the premise of restoring“living water”;using energy-saving technology to produce cheap“living water”;and using aerobic probiotics to enhance the ecological“activity”of the water body.Practice has proved that“living water”is a sustainable way to treat urban and rural eutrophic sewage.That is,to establish or restore aquatic ecosystem with aerobic probiotics as the core,to create or maintain the multi-directional circulating flow state of“living water”,to provide enough dissolved oxygen for the whole water body through the combination of ecology and artificial,thus forming a“living water”ecosystem with strong vitality and purification capacity.
