Problems solved by technology

However, in the MBR membrane technology for sewage treatment, the MBR membrane pollution treatment is complicated and expensive, and the conventional physical cleaning method is simple, but the cleaning is not thorough enough; and the external immersion chemical cleaning needs to consume manpower and resources, and the membrane module is taken out for cleaning. It is slow and inconvenient, and the cleaning is not thorough; the chemical cleaning method has been improved on the external dipping chemical cleaning method, which does not consume manpower and resources, and the cleaning is more convenient. However, the system needs to be shut down during the cleaning process and cannot be operated while cleaning. And shutting down and starting large equipment will reduce the service life of the equipment
[0003] For areas containing both domestic wastewater and oily wastewater, domestic wastewater and wastewater containing wastewater are treated in two different systems in the prior art, and domestic wastewater and oily wastewater need to be treated separately, and separate treatment requires a lot of energy. Human, material and financial resources are used to purchase, lay and manage equipment, wasting a lot of resources
[0004] The pretreated oily wastewater and domestic sewage have good biochemical properties. The commonly used treatment process is the combined process of "pretreatment + activated sludge", but the conventional "pretreatment + activated sludge method" not only occupies an area Large, and the treated effluent cannot meet the reuse requirements. Generally, it is necessary to add a set of reclaimed water reuse system to carry out advanced treatment on the effluent treated by the activated sludge method before it can be sent to the reuse water supply system. This greatly The increased complexity of sewage treatment
[0005] Nowadays, ultraviolet rays are commonly used in sewage disinfection to sterilize sewage, and the conventional method is to set up ultraviolet disinfection channels. Disinfection is not thorough, especially for the sewage at the bottom of the canal, and the water in the canal is too much. The mixing device consumes a lot of energy, power consumption and high cost
[0006] Disadvantages of existing technology: In the application of MBR membrane technology, MBR membrane pollution treatment is not thorough and the treatment cost is high; and for the simultaneous treatment of domestic sewage and oily wastewater, it needs to consume a lot of manpower, material and financial resources, wasting a lot of resources; disinfection Inadequate and costly

Abstract

The invention discloses a sewage treatment system of an MBR (membrane and bioreactor) membrane. The sewage treatment system comprises a pretreatment system and a sewage treatment system body. The sewage treatment system is characterized by comprising a biochemical aeration tank (1), an MBR membrane ultrasonic cleaning pool (2), an ultraviolet disinfection device (3) and a clean-water reservoir (4), which are orderly connected in series through a pipeline, wherein the pretreatment system is communicated with the biochemical aeration tank (1) through the pipeline. By adopting the sewage treatment system of the MBR membrane disclosed by the invention, the sanitary wastewater and oil wastewater can be synchronously processed; a lot of resources are saved; the sewage treatment system is easy to clean, thorough to sterilize, less in residual sludge output, small in floor area, convenient to operate and manage, easy to achieve automatic control and the like, also has excellent and stable effluent quality, and is not limited by the setting occasion.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an MBR membrane sewage treatment system. Background technique [0002] The rapid development of membrane technology has had a major impact on many fields, especially in the sewage treatment process. Membrane bioreactors combine the biodegradation function of traditional biological treatment technology and the efficient separation function of membrane separation technology. It has significant advantages such as high pollutant removal efficiency in sewage, stable effluent quality, convenient operation and management, and small footprint, and its application prospects are very broad. However, in the MBR membrane technology for sewage treatment, the MBR membrane pollution treatment is complicated and expensive, and the conventional physical cleaning method is simple, but the cleaning is not thorough enough; and the external immersion chemical cleaning needs to co...
