摘要
生态中水道是依靠排水管道的流体特性和其内在生态系统,利用生物强化技术,净化流入污水并最终实现污水回用的中水系统。生态中水道推流式反应器构型决定了其具有高效的净化能力。水流速度、水力停留时间和溶解氧水平都将对生态中水道的处理效率产生影响。而应用跌水充氧、自然拔风和动态调配技术可强化生态中水道的净化功能。
Eco-intermediate water supply is able to purify inflow wastewater by using its pipeline hydro-characteristic,internal ecosystem and bioaugmentation technology. Because of its plug flow model,it has effective purification ability. Meanwhile,the disposal efficiency is influenced by flow velocity,hydraulic retention time and dissolved oxygen. However,water-dropping aerating,ventilation piping and dynamic programming may contribute to strengthening the purification ability.
