Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] see Figure 1 to Figure 6 An air flotation device for high-concentration sewage treatment in a preferred embodiment of the present invention includes a pool body 1, which is provided with a contact chamber 2 and a separation chamber 3 that communicate with each other, and also includes a flocculation chamber that communicates with the contact chamber. There is a medicament feeding port 4 for agent or coagulant, and a releaser 5 for releasing dissolved air water and a stirring device for stirring the liquid are also provided in the contact chamber.

[0026] Specifically, the medicament dosing port may be a nozzle of a pipe whose top end protrudes from the liquid lev...

Abstract

The invention relates to a high-concentration sewage treatment air flotation device. The device comprises a pool body in which a contact chamber and a separation chamber which are communicated with each other are arranged, and further comprises a medicament adding hole which is communicated with the contact chamber and used for throwing in a flocculating agent or medicament, and the contact chamber is further provided with a release device for releasing water-soluble gas and a stirring device for stirring liquid. According to the high-concentration sewage treatment air flotation device, the flocculating agent body is difficult to sink, and the sewage treatment efficiency is high.

Description

technical field [0001] The invention relates to an air flotation device for sewage treatment, in particular to an air flotation device for high concentration sewage treatment. Background technique [0002] In the process of water supply and wastewater treatment, solid-liquid separation technology and its equipment are one of the key items. Conventional air flotation is mainly used in wastewater treatment where the separation density of suspended matter is similar to that of water, and the settling performance of suspended matter is poor. [0003] The main working principle of conventional air flotation is to dissolve the air and water into the water to the greatest extent under certain pressure and conditions, and then release the pressure of the formed pressure dissolved air water through the dissolved air releaser arranged in the contact chamber. , rapidly producing a large number of microbubbles. These microbubbles fill the contact chamber to form "white water" similar ...
