Description
Technical field
The invention belongs to the processing technology field of sewage, specifically, relate to a kind of MBR film sewage treatment system.
Background technology
The suggestion that develops rapidly of membrane technique has been brought great effect to various fields, particularly be applied to the sewage treatment process aspect, membrane bioreactor has merged the biological degradation function of traditional biologic treating technique and the high efficiency separation function of membrane separation technique, have significant advantages such as contaminant removal efficiency height in the sewage, stable effluent quality, convenient operation and management, floor space are few, application prospect is boundless.But in the MBR membrane technique at sewage disposal, the MBR film pollutes handles complexity, the expense height, and conventional physics purging method is simple, but cleans thorough inadequately; Need consume manpower and resource and flood matting outward, membrane module be taken out clean, speed is inconvenient slowly, and cleans not thorough; Chemical cleaning method floods on the chemical cleaning method outside and improves, and need not consume manpower and resource, it is comparatively convenient to clean, and still, needs closure systems can not accomplish the operation while cleaning in cleaning process, and close and start main equipment, the work-ing life that can reduce equipment.
And for both containing sanitary wastewater, the zone that oily(waste)water is arranged again, sanitary wastewater and the two kinds of different systems that are treated to that contain waste water in the prior art, need respectively sanitary wastewater and oily(waste)water to be handled, and take separate treatment need expend great amount of manpower and material resources and financial resources are carried out purchase, laying and the management of equipment, wasted a large amount of resources.
Pretreated oily(waste)water, sanitary sewage, good biodegradability, treatment process commonly used is the combination process of " pre-treatment+active sludge ", but not only floor space is big for conventional " pre-treatment+activated sludge process ", and the water outlet after handling do not reach the reuse requirement, generally need set up a cover intermediate water reuse system again, and advanced treatment is carried out in the water outlet after the Wastewater Treated by Activated Sludge Process, just can send into the reuse waterworks, and increase the complicacy of sewage disposal so greatly.
Wastewater disinfection ultraviolet ray commonly used now carries out disinfection to sewage, and routine is exactly that the disinfection by ultraviolet light canal is set, ultraviolet lamp carries out illumination-based disinfection to the sewage in the uv sterilisation canal, and be provided with whipping appts in the canal, sterilization while stirring, but this device is not thorough to wastewater disinfection, particularly thorough inadequately to the wastewater disinfection of canal bottom, and the many whipping apptss stirrings of channel water power consumption is big, and power consumption is many, the cost height.
The prior art shortcoming: MBR film pollution processing is thorough in the MBR Application of membrane, processing costs is high; And be directed to the synchronous processing of sanitary sewage and oily(waste)water, need expend lot of manpower and material resources and financial resources, wasted a large amount of resources; It is thorough inadequately to sterilize, the cost height.
