近年来利用灌井进行人工补给地下水的技术在国内外得到了广泛地应用,在解决地面沉降、贮能以及改善地下水开采状况等方面获得了明显效果。但在人工补给地下水过程中,往往会产生水质变化,灌井腐蚀或井下淤填,以致减少井的使用年限等都需进一步探讨。为此,在常州国棉一厂利用空调废水净化补给 In recent years, the technology of artificial recharge of underground water by using well-filling has been widely used both at home and abroad, and has achieved remarkable results in solving the problems of land subsidence, energy storage and groundwater exploitation. However, during the process of artificial recharge of groundwater, changes in water quality, corrosion of filling wells or siltation of the underground will often occur, so as to reduce the service life of the wells and the like, further discussions are needed. To this end, a plant in Changzhou Guomao air conditioning wastewater purification supplies
