摘要
研究了中空纤维膜清洗技术———连续微滤技术 (CMF) .从空气反冲和水反洗与空气振荡清洗交替进行 ,发展到气水双洗、在线加药剂清洗 ,再到空气振荡清洗、反洗、加药剂清洗过程 ,充分发挥各自清洗工艺的特点 ,实现在线清洗工艺的优化 ,从而实现连续过滤的目的 .该技术适用于污水处理、城市自来水净化处理。
A hollow fiber membrane cleaning technology named as Continuous Microfiltration (CMF) technology was studied.It came of backwashing by air or water,then work up cleaned membrane with air water at same time,gradually to air water washing with chemical agents on line washing,each process of air oscillation and water backwashing was exerted fully to optimize the on line cleaning technology.Using the CMF technology,we can realize on-line-cleaning for hollow fiber microporous membranes,thereby,carried out the purpose of constant production.It can be use to purify top water,city sewage,the pretreatment in the first stage of RO and etc.
