The Research on Zero Water Intake and Zero Emission of Optimization Technology in Beet Sugar Production
With the continuous development of sugar-making process,China's sugar production efficiency has been greatly improved.Through the technical transformation and optimization of production water,the traditional use of fresh water units are all replaced by cooling circulating water,supernatant and water,and realize the purpose of water supply by different quality,multipurpose of water,step use and the reuse of recycled water.On the basis of the original equipment of the sugar factory,plus the new construction of vertical flow settling tank,and add flocculent to the mud juice at the bottom of the spoke flow settling tank,the supernatant will return to the clear water pool after the secondary settlement,and then the demudding plate frame will be pressed and filtered,and the filtrate will return to the clear water pool to achieve the reuse of the settling recycling-water.Through this transformation,the fresh water used in the production sugar is reduced to less than 2.5 m3·t-1 sugar per ton,and the goal of energy saving,emission reduction,low carbon and environmental protection in sugar production is realized.
