土地处理技术在干旱-半干旱过渡带生态建设中的应用

土地处理系统是在干旱 -半干旱过渡区实现污水无害化、资源化的有效技术。内蒙古霍林河矿区污水土地处理系统设计与运行结果表明 ,该区具备推广土地处理技术的良好条件 ,土地处理系统应以慢速渗滤和污水资源利用型为主 ,实现污水处理与生态环境建设的结合。污水资源的利用有助于增加镶嵌型复合生态系统的稳定性 ,加速人工林的成林郁闭 ,增加林木蓄积量 ,改善干旱、半干旱地区的生态环境

Application of land treatment technology in ecological construction of arid-semiarid ecotone

Land treatment system is an effective technology for de harming and recycling wastewater in arid semiarid ecotone region.The design and operation of the land treatment system in Huolinhe Mining Field,Inner Mongolia showed that this region was well conditioned for extension of the land treatment technology,which should be based on recycling wastewater through slow rate filtration.Treatment of wastewater has to be combined with ecological construction.The application of wastewater is helpful in increasing stability of the complex eco system with mosaic structure,accelerating canopy closure and timber growing stock of the artificial forests,and improving the eco environment of the arid semiarid region.The social,economic and environmental benefits of the land treatment system are very remarkable.
