双膜法处理企业清净下水工程应用探讨

摘要

The drain off water enriching by boiler feed water and circulating water system was clear but with high salt, it could still have depth processing and comprehensive utilization after membrane treatment. Taking a chemical enterprise in Ningxia clean water recovery processing as an example, UF+RO double membrane method was used in processing waste water and recycling water production. As supplementary water in internal water circulation system, it was ensured to have system economy and reliability, effective technical solution can be used as a comprehensive utilization of waste water in most chemical companies use.%锅炉给水及循环水系统水质的浓缩后的外排水，水质清澈但盐分较高，经过膜法处理后仍然可以深度处理并综合利用。本文以宁夏某化工企业清净下水回收处理为例，采用UF+RO双膜法处理该部分废水并回收产水，作为企业内部循环水系统的补充水，确保其系统经济性和可靠性，可作为大多数化工企业废水综合利用的有效技术方案。
