Submergence type lift aeration apparatus

Abstract

The invention provides a suspending type lifting aeration device, which mainly comprises an aerator communicated with an external air supply through an air inlet pipe and an air bag type or pipe type floating drum connected with the aerator; the aerator is also provided with a lifting positioner which can realize the lifting positioning of the aerator and is provided with a lifting wire rope; the aerator is formed by the combination of at least two pipe type or disk type micropore aerators which are communicated with the soft air inlet pipe through air inlet branch pipes; the air bag type or pipe type floating drum is communicated with the external air supply through an air inlet-outlet hose; the lifting positioner at least comprises a set of pulley components and a lifting wire rope; and the pulley components also comprise positioning wheels arranged on the side part and the bottom part of a sewage reservoir, and by the pulley components and the positioning wheels, the lifting wire rope forms a vertical segment on the side part of the sewage reservoir, a horizontal segment on the bottom part of the sewage reservoir and a vertical segment below the aerator and is finally connected with the lower part of the aerator. The lifting aeration device has the characteristics that the lifting aeration device has simple structure and convenient use, and the aerator is made to suspend in the sewage reservoir, so that the positioning and the maintenance of the aerator are convenient, the project can be conveniently, continuously and stably operated for a long time, the use cost is lowered and the sewage treating effect can be improved.

Description

technical field [0001] The invention relates to an aeration device for sewage treatment, which belongs to sewage treatment equipment. Background technique [0002] There are many methods of sewage treatment, including aerobic biological treatment method, which is a relatively economical and effective method in the current sewage treatment methods. However, there are many factors affecting the effect of aerobic biological treatment, among which sufficient dissolved oxygen is required in the sewage, so in the aerobic biological treatment method, it is necessary to use an aeration device to supply oxygen to the sewage. [0003] A common aeration device consists of an air intake pipe and an aerator submerged in the sewage and connected to the air pipe. The air supply source, such as an air pump, blower, etc., passes through the air intake pipe, and then the air is respectively sent to the aerator to supply the sewage. gas to increase the dissolved oxygen in sewage. The aerator...

AI Technical Summary

Problems solved by technology

Therefore, these aeration devices in fixed positions will work in a harsh environment for a long time. Once some parts in the system are damaged, the water in the sewage tank can only be drained before local maintenance can be carried out. For large-scale sewage treatment In the factory, because it is difficult to drain the water in the large sewage tank, it is difficult to carry out partial maintenance and installation of the aeration device. Increase the cost of use and reduce the effect of sewage treatment
