This article introduces a newly-developed returning system of crushed bath from pot,which adopts existing mature technique and facilities and initiates a new way for transporting,mixing and feeding anode-covered material.

By studying impermeability and anti\|shear performance of the sludge from wastewater treatment plant with different water content (sludge a with 80 percent and sludge b with 45 percent), this article excludes the possibility of using sludge b as landfill final cover material but presents a proposition of utilizing sludge a.
