我国甘蔗糖厂节能减排技术发展

节能和减排是糖厂的重要课题，近年制糖工作者在这方面做了大量的工作，取得了良好的效果。我国2012/13年榨季制糖平均标煤耗对蔗比为4.69%，最好的甘蔗糖厂（集团）标煤耗对蔗比达到3.63%。通过制糖废水的闭合循环综合利用系统，使生产中工艺用水及非工艺用水得到分类处理和循环利用，实现了生产用水零取水，工艺废水零排放。本文对糖厂主要工艺过程的节能和减排技术措施进行阐述。

Technogical Development for Saving Energy and Reducing Pollution in Sugar Factories

Saving energy and reducing pollution is an important project for sugar factories. A lot of jobs had been done and good results had been obtained. In 2012/13 crushing season the average standard coal consumption was 4.69% in cane sugar factories in China. In the top sugar factory （group） the standard coal consumption was 3.63%. Because of the closed circulation and integrated use for wastewater in sugar processing, the process water and other water can been heated with classification and used with circulation. The zero water service and zero drainage of wastewater had been achieved in many factories. Sugar yield can be increased 2%（absolute value） and electricity consumption can be increased by 1/3 in the new crystallization process for producing brown sugar by the decreasing temperature method.
