摘要:

采用自行设计的室内土柱实验装置,模拟研究了含有硝态氮污染的河水在渭河渗滤系统中的环境行为及净化机制,其环境行为主要为反硝化作用.得出河流渗滤系统对硝态氮污水有很大的净化作用,其净化程度与该渗滤系统的渗滤介质有关,如果渗滤介质为细粒的黏土层,则对硝态氮污水净化程度很高,其净化率达到100%,但易引起地下水硬度升高等负效应.若介质为粗砂粒物质,其净化程度较低,但不易引起地下水硬度升高.

Abstract:

The environmental behavior and purification mechanism of river water containing nitrate nitrogen pollution in the infiltration system of Weihe River were simulated and studied by self-designed indoor soil column experimental device, and the environmental behavior was mainly denitrification. It is concluded that the river percolation system has a great purification effect on nitrate nitrogen sewage, and its purification degree is related to the percolation medium of the percolation system, if the percolation medium is a fine-grained clay layer, the purification degree of nitrate nitrogen sewage is very high, and the purification rate reaches 100%, but it is easy to cause negative effects such as increased groundwater hardness. If the medium is coarse sand substance, its purification degree is low, but it is not easy to cause the hardness of groundwater to increase.
