A kind of membrane module for sewage treatment being provided with monitoring device
Technical field
The present invention relates to field of sewage treatment equipment, be specifically related to a kind of membrane module for sewage treatment being provided with monitoring device.
Background technology
Along with industrial expansion, can produce much sewage in factory, sewage disposal device effectively can process the sanitary sewage in city, trade effluent etc., sewage and pollutent is avoided to flow directly into waters, to improving the ecological environment, promoting city taste and promote economic development significant.
Down-stream treatment facility most mostly now is type of precipitation, namely sewage enters in a large-scale pond, only putting by sewage, take contamination precipitation to, take out water clean for upper strata in disinfection, this type of process often receives the acceptance of majority because of cost cheap, but now some with more nervous in water, long treatment facility can not be effective, and is badly in need of a kind of processing speed and has not only filtered soon but also sewage disposal device thoroughly.
The suggestion that develops rapidly of membrane technique brings great effect to various fields, particularly be applied to sewage treatment process aspect, membrane bioreactor has merged traditional biological degradation function of biologic treating technique and the high efficiency separation function of membrane separation technique, have the significant advantages such as high to contaminant removal efficiency in sewage, stable effluent quality, convenient operation and management, floor space are few, application prospect is boundless.But in the MBR membrane technique of sewage disposal, the process of MBR fouling membrane is complicated, costly, conventional physical cleaning method is simple, but cleaning is thorough not; And outer matting of flooding needs to consume manpower and resource, membrane module is taken out cleaning, and speed is inconvenient slowly, and cleaning is not thorough; Chemical cleaning method, floods outside on chemical cleaning method and improves, need not consume manpower and resource, clean more for convenience, but in cleaning process, needing closure systems not accomplish, cleaning limit, limit is run, and close and start main equipment, the work-ing life of equipment can be reduced.
And for both containing sanitary wastewater, there is again the region of oily(waste)water, sanitary wastewater and be two kinds of different systems containing the process of waste water in prior art, need to process sanitary wastewater and oily(waste)water respectively, and take separately process to need the human and material resources of at substantial and financial resources to carry out the purchase of equipment, laying and management, waste a large amount of resources.
Pretreated oily(waste)water, sanitary sewage, good biodegradability, conventional treatment process is the combination process of " pre-treatment+active sludge ", but " pre-treatment+activated sludge process " of routine not only floor space is large, and the water outlet after process does not reach reuse requirement, generally needs to set up a set of intermediate water reuse system again, carries out advanced treatment to the water outlet after Wastewater Treated by Activated Sludge Process, reuse waterworks could be sent into, and add the complicacy of sewage disposal greatly like this.
Wastewater disinfection is commonly used ultraviolet and is carried out disinfection to sewage now, and routine is exactly arrange disinfection by ultraviolet light canal, ultraviolet lamp carries out illumination-based disinfection to the sewage in uv sterilisation canal, and be provided with whipping appts in canal, sterilize while stirring, but this device is not thorough to wastewater disinfection, particularly thorough not to the wastewater disinfection bottom canal, and the many whipping apptss of channel water stir power consumption greatly, power consumption is many, and cost is high.
Summary of the invention
Complex process, not thorough, the unhandy problem of sterilization that the present invention exists to solve the above-mentioned existing membrane module for sewage treatment mentioned, provide the membrane module for sewage treatment that a kind of result is simple, easy to operate, sterilization is provided with monitoring device thoroughly.
