摘要
河湖水体是各种污水排放的汇集地,随着经济的发展,排污总量的不断攀升已远远超出河湖水体自净能力,导致城镇地区的河道黑臭湖泊富营养化频发,河湖水体修复成为水生态建设中最为棘手的问题。常用的截污及清淤法均具有局限性,界面纳米水技术以低成本实现泥水共治,对底泥进行原位生态修复并维持长效,实现河湖水质和生态自净能力提升。
Rivers and lakes, as the sink of sewage discharge, have increasingly accumulated sewage far beyond its self-purification capacity with the development of the economy, resulting in black and odorous watercourse and frequent lake eutrophication in urban areas. Water body remediation has become the most tough task of ecological civilization construction. Compared with traditional methods such as sewage interception and desilting featuring limitations, interface nanotechnology can achieve co-treatment of mud and water at a low cost by remedying in-situ ecology of bottom mud and maintaining lasting effectiveness, which improves the water quality and self-purification capacity of lakes and rivers.
