摘要
Water resources are scarce in Jincheng. Huge quantities of water are pumped out in the dewatering course, and the disposal of CBM water is one of the most important problems during the extracting of CBM. Based on the data of CBM water production, chemical characteristics, the irrigational conditions for major crops, and China irrigation water standard, the feasibility of CBM water as irrigation water is discussed. The result shows the CBM water quality doesn't fully meet irrigation water quality standards in Jincheng, its high salinity and sodium adsorption ratio (SAR) in CBM water might affect crops growth and lead to yield loss, and can't be used as irrigation water directly, but with the treatment of the reverse osmosis (RO) to lower the salinity and SAR of CBM water, the CBM water can be used as irrigation water.
