Abstract

The invention discloses a membrane component tank with a dielectrophoresis pre-filtration structure. The membrane component tank comprises a membrane tank and a pre-filtration cavity, the pre-filtration cavity is positioned at the bottom of the membrane tank and connected with the membrane tank through a water inlet valve, a dielectrophoresis filtration structure is mounted in the pre-filtration cavity and comprises a metal stretching net electrode plate and a metal porous membrane structure electrode plate which are parallelly arranged up and down, connected with different output ends of an alternating current power supply and mutually insulated, and a membrane component device is arranged in the membrane tank and provided with a water outlet valve. The pre-filtration cavity with the dielectrophoresis filtration structure at the bottom of the membrane tank realizes pre-filtration, cleaner pre-filtration produced water is provided for the membrane component device in the membrane tank,the impact resistance of the membrane component device is improved, produced water flux is increased, the cleaning time and the service life of the membrane component device are prolonged, and the membrane component tank can be used for aerobic, anaerobic or direct filtration processes.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a membrane module box containing a dielectrophoresis pre-filter structure. Background technique [0002] With the continuous rise of my country's water purification and sewage treatment standards, membrane technology has been widely used in water purification, municipal sewage and water supply fields. Microfiltration and ultrafiltration form membrane modules in the process of integrated use, which are often operated by negative pressure suction. Membrane fouling is an unavoidable problem during operation. [0003] Dielectrophoresis describes the translational movement of electrically neutral particles located in an uneven electric field due to the effect of dielectric polarization. The dipole moment generated on the particle can be represented by two charges with the same charge but opposite polarity. When they are distributed asymmetrically on the particle interface, a macros...
