Description

Arcuation curtain formula MBR aeration branch pipe and curtain formula MBR aeration equipment

Technical Field

The utility model particularly relates to an arcuation curtain formula MBR aeration branch pipe and curtain formula MBR aeration equipment.

Background

At present, the MBR technology of the immersed membrane bioreactor is mainly applied to the sewage treatment industry, such as the treatment and reuse of urban sewage, the treatment fields of high-concentration organic wastewater, refractory industrial wastewater, public sensitive sanitary area wastewater and the like. The main functional components are a bioreactor and a membrane module, and a flat membrane module and a hollow fiber membrane module are two most commonly used membrane modules. The filling density of the hollow fiber membrane component is far higher than that of a flat membrane component, the investment is low, the applicable treatment scale can be large or small, the requirements of sewage treatment of different scales in different industries can be met, and the application is most extensive.

The hollow fiber membrane component applied to the immersed membrane bioreactor mainly comprises a curtain type membrane component, a seaweed type component and a membrane bundle type membrane component. The curtain type membrane assembly becomes the mainstream of the market due to the advantages of simple casting process, high unit filling area, low production cost, high membrane area flexibility of a single membrane assembly device and the like.

The MBR membrane module is the core of MBR engineering and becomes one of the research and development focuses of various large companies. Meanwhile, the MBR membrane group device is also one of the keys of the MBR membrane module whether to play a role effectively, and the aeration device is an important component of the membrane group device. In the conventional curtain type MBR membrane group, an aeration device is arranged at the bottom of a membrane component, an aeration branch pipe is positioned right below the curtain type membrane component, and airflow carries liquid flow to move upwards and is hindered by a lower end membrane shell to move in a direction away from the membrane component when reaching the bottom of the membrane component, so that fluid boundary layer separation is formed in the bottom area of the membrane component. The root of the lower end of the membrane component is an aeration dead angle, so that the effect of scouring membrane filaments by airflow is reduced, the root of the membrane filament is easy to accumulate sludge, and high-risk pollution is caused. In addition, the number of the aeration branch pipes is usually far less than that of the membrane assemblies, and is usually half of that of the membrane assemblies, so that one-to-one aeration cannot be realized, and the membrane assemblies without the aeration branch pipes are subjected to smaller gas scouring force and relatively faster pollution. When pollutants are accumulated to a certain degree, membrane filaments expand, membrane filaments of adjacent membrane components are bonded together to block an airflow ascending channel, and therefore pollution of the membrane components is accelerated. Finally, the conventional aeration branch pipe is usually a circular perforated pipe, and after the sludge mixed liquid enters the aeration branch pipe, the sludge mixed liquid is air-dried by gas to form hard solid particles which easily block aeration holes, so that the aeration is disabled, and the membrane module is seriously accumulated with sludge, thereby finally causing the membrane module device to be incapable of normally operating.
