本刊1989年第1期发表《压水机井的改进》一文后陆续收到读者来信,要求解答有关平原地区压水机井的水质问题。现将吴伟明同志撰写的《关于平原地区压水机井水质的改善问题》发表如下,并兼复杨先军同志。压水机井在我国农村推广、应用极其广泛,是因为它具有良好的卫生条件,汲取浅层地下水,提水效果好,构造简单,施工、使用方便等优点。但在实际推广应用中,读者来信反映,在当地 (平原地区)打井施工中,遇到饮用的压水机井井水,水质浑浊,煮粥烧饭会变紫色或铜绿色,烧开水镉边水面有一层白色状浮浊物,打井的成功率低等实际问题,如何解决?本文就上述的平原地区水质的检验与饮用水质的要求;压水机井的机型选择及施工;原水的净化处理;影响水质的原因等问题,浅述如下。
In the 1st issue of the “Pressure Improvement of Wells” published in 1989, the journal received letters from the readers asking for answers to questions about the water quality of the pressurized water wells in the plain area. Comrade Wu Weiming’s “Improvement on the Water Quality of Pressurized Pumping Wells in Plain Areas” is now published as follows, and he has also reconvened Comrade Yang Xianjun. The use of pressurized water wells in rural areas in China is extremely popular because of its good sanitary conditions, its ability to absorb shallow groundwater, its good water lifting effect, its simple structure, and its ease of construction and use. However, in practical application, the readers’ letter reflects that in drilling wells in the local area (plain areas), they encountered drinking water well water, and the water quality was turbid. The porridge cooking rice would turn purple or copper green, and the boiling water would be cadmium-side. There is a layer of white floating turbidity on the surface of the water. How to solve the practical problems of low drilling success rate? This paper discusses the above-mentioned requirements of water quality inspection and drinking water quality in plain areas; model selection and construction of water pressure wells; raw water Purification treatment; reasons that affect water quality and other issues are briefly described below.
