“生态活水”治水比较优势分析与应用

Comparative advantage analysis and application of“ecological living water”in sewage treatment

为探索黑臭水体治理的根本途径,在运用"生态活水"成功治理扬州黑臭水体基础上,探索了"生态活水"治水生态原理。通过对现行主流黑臭水体治理方法的分析评价,充分论述了"生态活水"治水技术特色和比较优势。研究表明,"生态活水"治水通过投放微生态制剂与原生态微生物结合创建"微生态系统"治理污水,具有设备投资省、治水效果好的特点;利用微速循环流水加速"微生态系统"对黑臭淤泥的生物氧化,净化功能强、治水效率高;通过及时补充溶氧和新鲜水、添加微生态制剂,达到维持水体生态系统稳定,运行成本低、可持续性强。其优势在于利用活水机械制造的微速循环流水,带动"微生态系统"全时空持续净化污水,极大提升污染净化效率。"生态活水"治水适合在水面较为宽敞、相对封闭或流速较为缓慢的污染水体治理中应用,如与人工湿地、植物浮床等治污方式结合,可取得更好的治理效果。

In order to explore the fundamental way of black and odorous water treatment,based on the successful treatment of Yangzhou black odorous water body with"ecological living water",the scientific principle of"ecological living water"for sewage treatment was explored.Based on the analysis and evaluation of the current mainstream black and odorous water treatment methods,the technical characteristics and comparative advantages of"ecological living water"in sewage treatment are fully discussed.The results show that the"ecological living water"treatment of sewage through the micro ecological agents and the original ecological microorganisms to create a"micro ecosystem"treatment of sewage,equipment investment is low,water treatment effect is good;through the micro speed circulating water to accelerate the"micro ecosystem"biological oxidation of black and odorous sludge,purification function is strong,water treatment efficiency is high;through timely supplement of dissolved oxygen and fresh water,add a series of beneficial bacteria can maintain the stability of water ecosystem,low operation cost and strong sustainability.Its biggest advantage lies in the use of a simple structure,very low energy consumption agitator to produce micro circulating water,driving the"micro ecosystem"to continuously purify sewage throughout the space-time,greatly improving the efficiency of pollution purification."Ecological living water"treatment of sewage is suitable for the treatment of polluted water body with relatively wide water surface,relatively closed or slow flow rate.If combined with the treatment methods such as artificial wetland and plant floating bed,better treatment effect can be achieved.
