Pool aeration system and aeration method thereof

Abstract

The invention relates to a pool aeration system and a aeration method thereof. The blower fan outlet pipes are respectively arranged at outlets of roots blower fans, an air supply valve is arranged atthe top of the blower fan outlet pipe, the outlet of the air supply valve and an air feed standpipe and the upwardly extended air feed standpipe are connected, the top of the air feed standpipe is connected with an air feed transverse pipe with horizontal extending along the top of the pool, several air feed branch pipes extending to the bottom of the pool are connected with the air feed transverse pipe, and the lower end of the air feed branch pipe is respectively connected with an air intake of a corresponding aeration head; a horizontally extended escape pipe is connected with a middle section of the blower fan outlet pipe, and an emptying valve is arranged at the outlet of the escape pipe. When aeration is carried out on the pool, the emptying valve is opened before starting, a blowerfan is turned on, after the blower fan is operated with a full speed, the air supply valve is opened, the emptying valve is closed and air is supplied to the pool, the emptying valve is opened for pressure relieving while shutdown, the blower fan is stopped, and the air supply valve and the emptying valve are closed. The aeration system and the aeration method realize zero-load starting and unloading of the blower fan, can avoid moisture erosion, and have long usage life.

Description

technical field [0001] The invention relates to an aeration system for a water pool, which aims at increasing dissolved oxygen in a water body. The invention also relates to an aeration method for a water pool, which belongs to the technical field of aeration facilities. Background technique [0002] The treatment of high-concentration organic wastewater usually includes an aerobic biological treatment process. The activated sludge method is the most commonly used aerobic biological treatment method. The complex microorganisms in the activated sludge and the organic nutrients in the wastewater form a complex food chain. Heteroxia bacteria and saprophytic fungi are the first to undertake the purification task. Bacteria, especially spherical bacteria, play the most critical role. The activated sludge with good operation is a bacterial gel group composed of spherical bacteria with filamentous bacteria as the skeleton. The settling property is good. With the normal operation of ...

Problems solved by technology

Damaged Roots blowers usually need to replace the impeller, oil seal and bearing. Since the gap between the impellers and between the impeller and the cylinder is very small, and the assembly accuracy requirements are extremely high, most users usually cannot complete the replacement by themselves, but can only replace it as a whole. Replacing the machine head will cause a lot of use cost
