Experimental Study on Stabilization of Sewage Sludge by MOC
污水厂污泥碱式胶凝稳定化研究

Magnesium oxychloride cement(MOC) was used for the stability agent in the stabilization experiments of sewage sludge.It is found that MgCl_2 in MOC is a kind of water-absorbent,water absorption of MgCl_2 can be achieved at 1.55(mL/g)(per 100 g sludge).Meanwhile,some water in sludge can be combined with MOC in the hydration reaction and sludge moisture content can be reduced efficaciously.The crystal structure of 3 phase and 5 phase,which occurred in the hydration process,makes the sludge compressive strengt...
