在含铁和锰较多的地下含水层中,可注入氧化剂促进铁和锰的沉淀,以改进其水质。在含水层的介质中,氧化剂或氧的移动,随着地下水流动和扩散、吸收过程而转移,进而产生化学作用及其变化。本文是采用回灌井注入富氧水的方法。为了设计回灌井和确定回灌率,必须预计含水层中氧化剂的上述动态。文中详细介绍现场实验方法和取得的数据,并以数学模式的计算值进行比较,最后认为这种方法简单易行,经济实用,并提出以下几个注意要点;
In aquifers containing more iron and manganese, oxidants can be injected to promote the precipitation of iron and manganese to improve the water quality. In the medium of the aquifer, the movement of the oxidant or oxygen is transferred as the groundwater flows and diffuses and absorbs, and then the chemical action and its change occur. This article is a method of injecting oxygen-enriched water into a recharge well. In order to design a recharge well and determine the recharge rate, the above-mentioned dynamics of the oxidant in the aquifer must be expected. The article introduces the field experiment method and the obtained data in detail, and compares them with the calculated values of the mathematical model. Finally, it concludes that this method is simple, economical and practical, and proposes the following points of attention;
