“生态活水”治水理论与战略价值的研究

Study on Theory and Strategic Value of Sewage Treatment with “Ecological Live Water”

水污染是城乡水体普遍现象,治理水污染已成为生态文明建设的重大课题。'生态活水'治水是寓生态于活水之中治理污水,通过构建以系列高活力有益菌和原生态浮游动、植物组成的'微生态系统',并逐步修复或重建多样化生物构成的生态系统治理污水;并通过活水机造就微速循环流水,实现了'四维'全时空(即全水面、全水层、全时段、全天候组成)持续高效净化污水。'生态活水'治水是在原污染水体中建立以两类微生物为核心的生态系统治理污水,并以保持生态系统的稳定性及其强劲污染净化能力为核心开展日常维护工作,只须根据天气状况和周围污染排放情况,适时适度调整增氧、引水、补菌强度,持续保持微速循环流水,保持生态系统稳定和强劲污染净化能力,具有明显效率优势和成本优势,处于国际领先地位。因此,'生态活水'治水是一种占用资源少、设备投资省、治污速度快、运行成本低、可持续性强的治水方式。

Water pollution is a common phenomenon in urban and rural water bodies.Sewage treatment has become a major issue in the construction of ecological civilization.'Eco-living water'is a way to treat sewage by incorporating ecology into flowing water.By constructing a'micro-ecosystem'consisting of a series of highly active beneficial bacteria and original zooplankton and plants,and gradually restoring or rebuilding an ecosystem composed of diverse organisms,the sewage can be treated.By the function of water mixing machinery,micro-circulating water can be created to realize the whole time and space of sewage treatment.'Four-dimensional'means the treatment of sewage in the whole waters,24 hours and various meteorological conditions.'Ecological living water'control is to establish an ecosystem with two kinds of microorganisms as the core in the original polluted waters for sewage treatment,to maintain the stability of the ecosystem and its strong pollution purification capacity as the core,and to carry out daily maintenance work.It is only necessary to adjust the intensity of oxygen enrichment,water diversion and bacteria replenishment timely and moderately according to the changes of weather conditions and surrounding pollution discharge,and to circulate water at a micro-speed.Under this condition,maintaining the stability of the aquatic ecosystem and its strong pollution purification capacity has obvious efficiency advantages and cost advantages,and is in the leading position in the world.Therefore,the'ecological living water'is a water control method with fewer resources,less investment in equipment,fast pollution control speed,low operating cost and strong sustainability.
