Problems solved by technology

However, there are two main problems in the built-in membrane bioreactor: one is that the installation, maintenance and cleaning of the membrane modules are very inconvenient, and the cleaning labor intensity is high; It is 3-4 times that of other mature sewage biological treatment processes at present, which makes its energy consumption per ton of water still significantly higher than other processes
However, one disadvantage of this patent is that the flow state of the liquid flow inside the shell is not good, and the end of the membrane module is prone to sludge accumulation
The disadvantage of this patent is also that the flow state of the liquid flow inside the shell is not good, and the end of the membrane module is prone to mud accumulation

Abstract

The invention discloses a cylindrical membrane component, which comprises a shell, an end cover of the shell, a filtering unit inside the shell, a liquid inlet port and a liquid outlet port, wherein the position of the liquid inlet port is lower than the lower end of the filtering unit or higher than the upper end of the filtering end. The invention also discloses a membrane bioreactor and a water treatment device by using the cylindrical membrane component. By the structural feature of the inventive cylindrical membrane component, the liquid to be filtered is introduced into the membrane component from the lower side or the upper side of the filtering unit, so as to improve the flow regime of the liquid inside the membrane component, prevent sludge accumulation at the end of the filtering unit arising from the sudden turning of the liquid to be filtered in the filtering unit when flowing in / out of the shell, improve the fouling resistance of the membrane component, and effectively prevent the service life shortage of the overall membrane component due to the rapid development and spreading of pollutants at the end of the filtering unit.

Description

technical field [0001] The invention relates to membrane separation water treatment equipment, in particular to a column membrane module applied to water treatment, a membrane bioreactor using the column membrane module and water treatment equipment, belonging to the technical field of water treatment. Background technique [0002] Membrane Bioreactor (MBR) process is an efficient sewage treatment and reuse technology that organically combines membrane separation technology and traditional biological treatment technology. Compared with other sewage treatment processes, it has excellent and stable effluent quality and occupies less land With outstanding advantages such as small area, strong impact load resistance, and low excess sludge output, it is a water treatment process with great development potential, especially in terms of sewage recycling. MBR process can convert domestic sewage, urban sewage or similar industrial waste water The one-step treatment of wastewater into...
