摘要
Hereinafter we introduce a system of water lime treatment with sludge recycle. This system will eliminate many problems encounted in conventional water softening treatment system, such as consuming a large amount of commodity hoe and the problem of sludge disposal. In this system the sludge of calcium carbonate from the reaction Will be calcined to quicklime and partially re-used in the system itself, the surplus quicklime can be sold out. Nearly no wastewater and wasteslag are disposed during the treatment process.
