Experimental research was performed to the properties of sludge thickening by increasing the pressure and shortening the path of water flowing in laboratory. And the relations between the diameters of sand columns and pressure on sludge water thickening were obtained. The results show that shortening the drainage path can enhance the compression effect, and the increasing of pressure can force water pass through filter layer quickly. The dosage of flocculants can be generally controlled; hereby can afford flocculants the variety and quantity in the process. The research results will be the guidance to the sewage treatment plants for tomorrow and to improve the current municipal wastewater treatment plants.
