摘要: The research on Constructed Soil Rapid Infiltration (CSRI) system is in its infancy at home and abroad. There are several
details about the mechanism and application of CSRI system needed to be further studied. A major limitation in the current research is
the absence of degradation dynamics of pollutants, and the height of filtration bed in CSRI system currently determined by empirical
judgment lacks accuracy and logicality. To solve these two problems, the soil column of CSRI system was utilized to treat domestic
wastewater, meanwhile, the NH3-N degradation dynamics were studied according to the Monod equation, the research of Mann A T and
the NH3-N degradation law. Then the mathematical model of filtration bed height was built based on NH3-N degradation dynamics
equation in the soil column. It has been proven that within a limited range this model can calculate the appropriate height of filtration bed
accurately in order to optimize technological parameters of hydraulic load and the concentration of influent NH3-N, improving the effluent
quality of CSRI system.
