Intelligent sewage purification apparatus

Abstract

The invention discloses an intelligent sewage purification apparatus. The apparatus comprises a water collecting pool, wherein a water inlet of the water collecting pool is provided with a mechanical grid, a water outlet of the water collecting pool is connected with a water inlet of a sedimentation pool, the sedimentation pool is connected with an anoxic pool, the anoxic pool is connected with a MBR pool, the bottom of the MBR pool is provided with an aerator, oxygen is continuously introduced into the MBR pool through the aerator, a water inlet of the MBR pool is provided with a solenoid valve, the solenoid valve is connected with a solenoid valve controller, a MBR membrane assembly is arranged in the MBR pool, the opening and closing of the solenoid valve is controlled by the solenoid valve controller, and thereby the opening and closing of the water inlet of the MBR pool is controlled. According to the apparatus, two-way vibration adjusting cylinders are arranged between upper and lower position-limiting sliding seats, the two-way vibration adjusting cylinders drive the upper and lower position-limiting sliding seats to continuously approach and move away by movements, and thereby a fiber membrane is continuously folded and stretched, through large-scale folding and stretching vibration, a large amount of filtered impurities accumulated on the surface of the fiber membrane is removed by vibration, and the frequency of disassembling and cleaning of the fiber membrane is reduced.

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...

[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 fiber membranes. At the same time, after a period of sewage treatment due to There are a large amount of pollutants accumulated in the filtration of the membrane module, and the fiber membrane in the membrane module needs to be cleaned. In the prior art, the fiber membrane is usually directly removed and cleaned, and the fiber membrane is usually directly fixed on the fixing frame. Inconvenient, which increases the labor intensity of each cleaning of the fiber membrane, and frequent cleaning is inconvenient
