山梨酸废水处理工艺的技术改造

摘要

On the basis of characteristics of wastewater from sorbic acid production, facilities, field, and technology of Jilin chemical fiber wastewater treatment factory were reused, and technical renovation and economy compensation were adopted in treating chemical wastewater of sorbic acid for Jilin sorbic acid Co., Ltd.By transformation of the regulating aerated tank, horizontal settling tank and inclined plane tank of the original pretreatment system into the hydrolytic acidic basin and contact aeration basin, as well as the design of dual A/O process, the treatment of sorbic acid wastewater has reached the discharge standard of class 1 in GB8978-1996. And a scientific support was provided for reformation of the district pollution control system.%通过技术改造和根据山梨酸废水特点,利用了吉林化纤污水处理厂的设施、场地和技术等资源,较好地设计和处理了吉林山梨酸有限公司的废水.经过把一个原污水预处理系统的调节曝气池、平流沉淀池和斜板沉淀池改造为水解酸化池和接触氧化池,以及经过双级A/O工艺设计和废水处理,山梨酸废水处理达到了GB8978-1996一级排放标准目标,为区域水污染治理和系统改造提供了科学依据.
