坡度、水力负荷及布水方式对地表漫流系统冲刷率的影响

Influences of Slope Hydraulic and Water Distribution Manner on Erosion Rate in Overland Flow Land Treatment System

在进行白银西机务段洗车废水的土地处理实验研究中，通过对地表浸流污水土地处理系统中平顶堰槽布水和喷灌布水的动态模拟实验研究，探索了不同运转条件下两种布水方式对系统中土壤冲刷的规律；同时给出了不同坡度水力负荷条件下冲刷率的定量分析数学关系式．为进行地表漫流污水土地处理系统的实验研究、工艺设计提供了依据和定量分析方法．

Through the researches and experiments on dynamic water distribution modelfing of the tunnel with flat-top weir and spray irrigation manner in overland flow land treatment system of wastewater,the regulations of soil erosion in the system influenced by water distribution ways are studied at the different operation conditions,which is one of the research items of land treatment for washing wastewater produced in West Baiyin Engine Workshop.Besides,ite mathematical equations are derived to quantitatively analyze erosion rate under various slop and hydraulic conditions.The results provide the foundation and analysis methods for further research and technical design of overland flow land treatment system of wastewater.
