【 摘 要 】

A three-dimensional (abbreviation 3D) cilia filter cloth of high lifetime was introduced because the ordinary filter cloth has short service lifetime and unsatisfactory results when it was applied in mechanical dehydration. The dehydration effect of 3D filter cloth is much better than that of ordinary filter cloth. The 3D filter cloth could withstand six times higher tension above the ultimate tension of ordinary filter cloth. The effect of dehydration under higher pressure for 3D cloth is greater than that under lower pressure. The 3D filter cloth decreased the water content of dehydrated mud cake by an average of about 18% compared with the ordinary filter cloth. The water content of mud cake was lower than 59%, combined with preconditioning technology for the sludge, which achieves reduction and resource utilization of sludge.
