Embodiment 1

[0016] The evaporative I-effect condensed water is separately treated by one, two or more combinations of sand filter, activated carbon, ion exchange resin, reverse osmosis, and nanofiltration devices to meet the drinking water index.

Embodiment 2

[0018] Evaporation II effect condensed water is individually treated by one, two or more combinations of sand filter, activated carbon, ion exchange resin, reverse osmosis, and nanofiltration devices to meet the drinking water index.

Embodiment 3

[0020] Mix evaporation I and II effect condensate water according to a certain ratio, and pass through one, two or more combinations of sand filter, activated carbon, ion exchange resin, reverse osmosis, and nanofiltration devices to achieve drinking water indicators.

Abstract

The invention discloses a method for producing drinking water by utilizing steam condensation water of a sugar refinery. In the method, the steam condensation water of the sugar refinery is subjected to one, two or more devices of a sand leach device, an active carbon device, an ion exchange resin device, a reverse osmosis device and a nanofiltration device in order to reach the standard of the drinking water. The invention can effectively recycle the steam condensation water, increase the comprehensive utilization approaches for the sugar refinery, improve the economic benefit and can reduce the exhaust of the waste water of the sugar refinery.

Description

technical field [0001] The invention relates to a method for producing drinking water, in particular to a method for producing drinking water by utilizing evaporated condensed water in a sugar factory. technical background [0002] Water is the source of life, an indispensable and important substance in human life and production activities, and an irreplaceable important natural resource. With economic development, population growth and improvement of people's material and cultural living standards, the demand for water around the world is increasing day by day. In the 1960s, water crises began to occur in some countries and regions. Water issues have aroused widespread concern in contemporary countries . [0003] There is about 75% water in sugarcane. In the process of sugar production, this part of water and sugar are extracted together by high pressure to form a sugar solution of about 15°Bx. After clarification, it is evaporated and crystallized to remove a large amount...
