柬埔寨甘丹省莫穆坎普区水文地质特征研究

A study on the hydrogeological characteristics of Mok Kampoul district in Kandal Province,Cambodia

柬埔寨位于东南亚中南半岛南部,随着人口的不断增长和经济的快速发展,水资源供需矛盾日益突出,特别是农村地区饮水安全面临巨大挑战。本文主要对柬埔寨甘丹省莫穆坎普区地下水展开综合研究,通过研究表明:该区地下水类型主要为第四系松散岩类孔隙水和火山岩类基岩裂隙水。第四系孔隙水pH值为6.8~7.9,总硬度范围55~145mg/L,矿化度范围168.5~285.8mg/L,地下水水质类型为III-IV类;基岩裂隙水pH值为8.0~8.3,总硬度范围148.47~448.88mg/L,矿化度范围522.6~1150.6mg/L,地下水水质类型为IV类,Na含量普遍较高,为314~317mg/L,适用于农业和工业用水,适当处理后可作为生活饮用水和集中供水水源。

Cambodia is located in the south of Indochina Peninsula in Southeast Asia.With the continuous growth of population and the rapid development of economy,the contradiction between supply and demand of water resources has become increasingly prominent,especially in rural areas,where drinking water security is facing great challenges.This paper mainly studies the groundwater in momukamp District,Gandan Province,Cambodia.The results show that the groundwater types in this area are mainly Quaternary loose rock pore water and volcanic rock bedrock fissure water.The pH value of Quaternary pore water is 6.8~7.9,the total hardness is 55~145 mg/L,and the mineralization degree is 168.5~285.8 The results show that the groundwater quality type is III-IV;the pH value of bedrock fissure water is 8.0~8.3,the total hardness range is 148.47~448.88 mg/L,the mineralization degree is 522.6~1150.6 mg/L,the groundwater quality type is IV,the Na content is generally high,314~317mg/L,which is suitable for agricultural and industrial water,and can be used as drinking water and centralized water supply source after proper treatment.
