MBR hollow fiber membrane wastewater treatment device

Abstract

A disclosed MBR hollow fiber membrane wastewater treatment device comprises a purification cylinder, the top of the purification cylinder communicates with a water inlet pipe, the bottom of the side face of the water inlet cylinder communicates with a water outlet pipe, the inner wall of the purification cylinder is fixedly connected with a supporting plate layer, and the supporting plate layer divides an inner cavity of the purification cylinder into two parts; and a valve funnel is installed on the supporting plate layer, the two parts of the inner cavity communicate with each other through the valve funnel, and an MBR membrane layer is fixedly installed on the inner wall of the purification cylinder. According to the MBR hollow fiber membrane wastewater treatment device, in the rotating process of stirring blades, small magnets on the stirring blades can rotate along with the stirring blades, and when the small magnets move to the position below a cleaning ball, due to the fact that magnetic layers on the surface of the cleaning ball and the small magnets have the same polarity, the cleaning ball overcomes gravity and swings upwards and impacts a primary filter screen under the action of repulsive force of the small magnets; and at the moment, the swing rod swings around a fixed column, so that the primary filter screen is vibrated and prevented from being blocked, and the cleaning ball periodically knocks the primary filter screen, so that the anti-blocking effect of the primary filter screen is better.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an MBR hollow fiber membrane wastewater treatment device. Background technique [0002] MBR wastewater treatment is a common way of modern wastewater treatment. It adopts membrane bioreactor technology, which is a new technology combining biological treatment technology and membrane separation technology. It replaces the secondary sedimentation tank in the traditional process, and it can efficiently Solid-liquid separation is carried out to obtain stable reclaimed water for direct use, with low energy consumption and small footprint. [0003] However, in the traditional MBR wastewater treatment devices, few of them are cleaned and treated. Due to the large amount of impurities and harmful substances in the wastewater, the treatment devices may become clogged after long-term use, resulting in reduced decontamination effect. And if it is not cleaned for a long time, i...

[0003] However, in the traditional MBR wastewater treatment devices, few of them are cleaned and treated. Due to the large amount of impurities and harmful substances in the wastewater, the treatment devices may become clogged after long-term use, resulting in reduced decontamination effect. And if it is not cleaned for a long time, it is likely to cause damage to the treatment device and reduce the service life of the treatment device, thereby increasing the cost of decontamination
