Description
Technical Field
The invention relates to the technical field of aerator cleaning, in particular to a cleaning method for cleaning an aerator by micro-nano bubbles.
Background
Aeration is to introduce air into a biochemical aeration tank through proper equipment to achieve the expected purpose, and is a means for promoting the exchange of substances between gas and liquid. The aeration not only makes the liquid in the pool contact with the air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the stirring of the liquid, thereby completing the purpose of oxygenation; in addition, the aeration also prevents the suspension body in the pool from sinking, and strengthens the contact of the organic matters and the microorganisms in the pool with dissolved oxygen, thereby ensuring that the microorganisms in the pool carry out oxidative decomposition on the organic matters in the sewage under the condition of sufficient dissolved oxygen. The quality of the aeration device not only affects the biochemical treatment effect of sewage, but also directly affects the land occupation, investment, operation cost and the like of a treatment plant. Aeration is widely applied to biological treatment processes, such as a common activated sludge method and a biological contact oxidation method, and becomes an important sewage treatment link.
The microporous aerator is one of common aeration devices, and generally comprises an aeration disc (aeration pipe), a tank bottom main pipe, branch pipes, a pipeline support, an expansion joint, a water removal system and the like, and simultaneously needs to be matched with an air blower and a corresponding pipeline system.
After the aerator runs for a long time, calcareous and ferrous scale deposits in water are easily deposited on the aeration membrane, and the scale deposits block the holes of the aerator to influence the aeration effect, so that the oxygenation capacity and the stirring performance are greatly reduced.
The current common methods for cleaning the aerator all need to stop production regularly and empty the aeration tank before the cleaning step is executed, the blocked aerator cannot completely recover the ventilation volume after cleaning, certain damage can be caused to the aerator in the cleaning process, and the normal service life of the aerator is shortened. However, conditions of stopping production and emptying the aeration tank are difficult to realize in sewage plants, and a new aerator can be arranged and replaced only when the aerator to be treated is blocked and the normal production is seriously influenced (the normal operation of a blower is influenced and the standard of effluent is influenced).
