Manufacturing method of denitrification biological reaction module for intercepting farmland non-point source pollution
The invention relates to the technical field of ecological repair, in particular to a manufacturing method of a denitrification biological reaction module for intercepting farmland non-point source pollution, which comprises the following steps: a, selecting specific areas as construction areas in farmland, between farmland and stream and between farmland and river; b, construction operation is conducted in the construction area, and one or more interception pits are obtained; c, wood chips are flatly laid at the bottom of the interception pit obtained in the step b, and a reaction layer is formed; and d, soil dug out when the interception pit is obtained through construction operation is backfilled into the interception pit, a backfilled soil layer is formed, and the upper surface of the backfilled soil layer and the upper surface of the soil layer on the periphery of the construction area are kept flat. The device has the advantages that agricultural non-point source pollutant nitrogen can be better and effectively intercepted, secondary pollution can be avoided, and waste of the agricultural planting area can be avoided.
本发明涉及生态修护技术领域，特别是涉及一种拦截农田面源污染的脱氮生物反应模块的制作方法，包括以下步骤：a、在农田、农田与溪流之间以及农田与河流之间选取特定区域面积作为施工区域；b、在施工区域施工作业并得到一个或一个以上的拦截坑；c、在b步骤中得到的拦截坑的底部平铺设置木屑碎并形成反应层；d、将施工作业得到拦截坑时挖出的土回填至拦截坑内并形成回填土层，且使得回填土层上表面与施工区域周边土层上表面保持平整。本发明具有能够更好的对农业面源污染物氮进行有效拦截，能够避免产生二次污染，能够避免对农业种植面积造成浪费的特点。
