摘要
污水土地处理系统的渗透性是能否实现污水处理设计要求的关键。本文采用地下水数值模拟方法刻画了污水土地处理系统复杂的结构和边界条件,准确地得到了能够满足污水处理设计要求的污水土地处理系统的渗透系数,并通过不同砂-土混合比例的重塑土渗透试验,研究了能够满足污水处理设计要求的重塑土的砂-土混合比,以为充分利用原场地黏土资源提供依据,也为类似研究和设计提供新的思路和方法。
In the design of wastewater land treatment system, soil permeability is critical to the sewage treatment. This paper applies numerical simulation to describing the complex construction and boundary conditions of the wastewater land treatment system,and obtains the permeability coefficients satisfying the design requirements of the wastewater land treatment system. Meanwhile,through the permeability testing of remolded soil with different sand-clay ratios, the paper figures out the mixing ratios of remolded soils satisfying the design requirements. This study provides some basis for taking the full advantage of in situ clay resource and also the new mentality and method for similar researches and designs.
