Problems solved by technology

However, during the growth of biofilm on the surface of the membrane module, due to the differences in the water environment conditions of each part of the membrane module, the thickness of the biofilm is not uniform, and it cannot be uniformly attached. Shedding, and then it is easy to cause large-scale shedding, reducing the efficiency and stability of MBfR

Abstract

The invention discloses a shell and a membrane bio-membrane reactor, and belongs to the technical field of sewage treatment. The shell comprises a hollow main body, an upper membrane fixing assembly located at a first end of the main body and a lower membrane fixing assembly located at a second end of the main body; the main body is used for accommodating membrane assemblies, and the upper membrane fixing assembly and the lower membrane fixing assembly are used for fixing the position of the membrane assemblies; at least a part of the upper film fixing assembly is located in the main body; a first step part is arranged at the position, close to the first end, of the inner wall of the main body, the outer diameter of at least a part, located in the main body, of the upper membrane fixing assembly is larger than an inner diameter corresponding to the first step part, and the height difference between the first end and the first step part is larger than or equal to the height of the lowermembrane fixing assembly. The shell provided by the invention is used for the membrane bio-membrane reactor, and the high efficiency and stability of the reactor can be improved.

Description

Technical field [0001] This application relates to the technical field of sewage treatment, in particular to a shell and a membrane biofilm reactor. Background technique [0002] In the 21st century, my country has begun a rapid urbanization process. The water environment of most cities is facing threats such as increased water pollution, deterioration of water quality, increased pollution of drinking water sources, and shortage of water resources. Sewage treatment technology has been rapidly developed. Development, especially the biological treatment process. Among them, the new water treatment technology-Membrane Biofilm Reactor (MBfR) technology has the most outstanding effect and cost, and it is widely used in O 2 , H 2 , CH 4 Utilization and transformation of waste water to achieve biological wastewater treatment. However, during the growth process of the biofilm on the surface of the membrane module, due to the differences in the water environment conditions of each part of ...
