Abstract: Sandy loam is the main soil in the arid area of North China, which leads to serious water shortage. Therefore, the utilization of non-traditional water is necessary. However, there are many metal mining areas in the northern arid area. The mining process of these metal mines causes the pollution of surrounding water sources. It is important to study the distribution of pollutants in the process of unconventional water utilization around metal mines. In view of the above problems, a field test area was established near a mining area in a northern province to carry out research on non-traditional agricultural water applications. The influence of non-traditional agricultural water on pollutant distribution in balsam pear and sandy loam irrigation areas around a loam metal mine was analyzed. By discussing the influence of non-traditional water output after secondary treatment on the content and distribution characteristics of heavy metals in balsam pear in the sandy loam irrigation area around the metal mine, the distribution rules of heavy metals in the soil crop system under different non-traditional hydroponics conditions in the sandy loam irrigation area around the metal mine were analyzed. The results show that under different non-traditional agricultural water consumption conditions, there is no significant difference in terms of the content of heavy metals in the sandy loam irrigation area around the metal mine. The non-traditional water used for short-term agricultural application does not cause pollution of the loam environment and crops, nor does it cause heavy metal accumulation in the sandy loam irrigation area around the metal mine. The input and output have a minimal impact on the balance of heavy metals in the sandy loam irrigation area around the metal mine. The presented research results provide a scientific basis for agricultural utilization of non-traditional water around mining areas in arid areas.
