Problems solved by technology

Once the aeration tube is uneven for some reason, more gas will be discharged in the relatively high aeration tube, and less gas will be discharged in the relatively low aeration tube, thus affecting the uniformity of aeration
[0003] In order to adapt to this feature of the aeration process, the bottom plate of the aeration tank in the water treatment plant is usually made horizontal, which brings about the problem that the design of the aeration tank is limited by the horizontal installation conditions of the aeration pipe
At the same time, if multiple aeration tanks share one fan, it is also necessary to ensure that the aeration pipes of each aeration tank are at the same horizontal position. Uneven settlement and other conditions will lead to uneven aeration

Abstract

The invention discloses a pressure dividing control method for aeration. A pressure divider is arranged in an aeration tank, and the back pressure of aeration pipes with different installation heightsis balanced through the pressure divider, so that the function that the gas pressure is adjusted with the back pressure of each aeration pipe in the aeration process is realized. An aeration pressuredividing device applied in the method of the invention can realize divided-pressure aeration of a same aeration system, and in the case that the installation heights of the aeration pipes are not thesame, the flow rate stability of the aeration pipes can still be guaranteed, thereby effectively avoiding non-uniform aeration phenomena due to inconsistent installation heights of the aeration pipes.

Description

technical field [0001] The invention relates to an aeration partial pressure control method. The method is mainly used in the aeration process of water treatment. Through the partial pressure control method, a single pressure gas source is divided into multiple pressure values, and can be applied to the aeration process of water treatment requiring multiple aeration pressures. Background technique [0002] The aeration process is one of the commonly used processes in water treatment plants. The aeration process not only has the function of oxygenation, but also has the function of fluidizing the water body. Usually, the aeration process of water treatment plants uses the same pressure air source, and the aeration pipe must be kept horizontal to ensure uniform aeration. Once the aeration tube is uneven for some reason, more gas will be discharged in the relatively high aeration tube, and less gas will be discharged in the relatively low aeration tube, thus affecting the uni...
