An intelligent sewage purification device

Abstract

The invention discloses an intelligent sewage purification device, comprising a water collecting tank, a water inlet of the water collecting tank is provided with a mechanical grille, at the same time the water outlet of the water collecting tank is connected with the water inlet of a sedimentation tank, the sedimentation tank is connected to an anoxic tank, The oxygen tank is connected to the MBR tank. An aerator is arranged at the bottom of the MBR tank, and oxygen is continuously fed into the MBR tank through the aerator. A solenoid valve is arranged at the water inlet of the MBR tank, and the solenoid valve is connected to the solenoid valve controller. At the same time, the MBR membrane module is installed in the MBR pool, and the solenoid valve is controlled to open and close through the solenoid valve controller, thereby controlling the opening and closing of the water inlet into the MBR pool. In the present invention, a two-way vibration adjusting cylinder is arranged between the upper and lower limit sliding seats, and the two-way vibration adjusting cylinder drives the upper and lower limit sliding seats to approach and move away continuously through movement, so that the fiber membrane is continuously folded and stretched. The folding and stretching vibration makes a large amount of impurities accumulated and filtered on the surface of the fiber membrane removed by vibration, which reduces the frequency of removal and cleaning of the fiber membrane.

Description

technical field

[0001] The invention belongs to the field of sewage treatment and relates to an intelligent sewage purification device. Background technique

[0002] In the existing sewage treatment process, MBR technology is usually installed in it. MBR is a new type of high-efficiency sewage treatment process that combines high-efficiency membrane separation technology with traditional activated sludge. It uses a submerged membrane module with a unique structure. In the aeration tank, the water after aerobic aeration and biological treatment is pumped out after being filtered through the filter membrane. The existing MBR membrane modules are usually directly fixed on the fixing frame, and the fiber membrane in the MBR membrane module The connection between them is relatively tight. When in water, even if the aeration treatment is carried out continuously, the dissolved oxygen between the fiber membranes is low, which reduces the reproduction of aerobic bacteria between the...
