Problems solved by technology

[0002] A lot of industrial wastewater contains impurities such as surfactants. During the treatment process at the wastewater station, a lot of foam is generated. Bubbles, more and more foam will overflow the pond to pollute the land, or enter the municipal sewage pipe network with the drainage. During the process of flowing through the municipal pipe network, the foam may overflow the sewage well. At present, the defoaming method commonly used in sewage stations It is to add a defoamer, but the price of the defoamer is expensive, which greatly increases the cost of sewage treatment. Taking a sewage station that treats the wastewater produced by auto parts with a treatment capacity of 150,000 tons per year as an example, the use of the defoamer for one year The cost is about 200,000, and the cost of defoaming agent accounts for about half of the cost of all chemicals in the sewage station

Embodiment Construction

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, a kind of simple and easy physical defoaming method of the present invention, the waste water with foam that the waste water station treats up to standard is connected in the plastic barrel 3 through the liquid inlet pipe 1, and the liquid inlet pipe 1 is connected from the upper end side of the plastic barrel 3 Connected, the waste water mixture with foam is separated in the plastic bucket 3, the foam is at the upper end of the plastic bucket 3, the water is at the lower end of the plastic bucket 3, and the foam is discharged from the foam removal pipe 2 connected to the plastic bucket 3, and discharged to the regulating tank 3. The pool defoams naturally, and waste water without foam is removed from the dr...

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a simple physical defoaming method. The invention discloses a simple physical defoaming method, and the method comprises the following steps: introducing foamed wastewater which is treated in a wastewater station and reaches the standard into a plastic barrel through a liquid inlet pipe, and connecting the liquid inlet pipe from the side surface of the upper end of the plastic barrel, separating a foamed wastewater mixture in the plastic barrel, wherein foam lies at the upper end of the plastic barrel and water lies at the lower end of the plastic barrel; discharging foam from a foam discharging pipe connected to the upper end of the plastic barrel to an adjusting tank for natural defoaming, discharging waste water without foam from a liquid discharging pipe connected to the lower end of the plastic barrel, and guiding waste water discharged from the liquid discharging pipe to a drainage channel of a sewage station to be discharged. Defoaming can be realized without adding a defoaming agent, so that the defoaming cost is reduced, and the economic benefits of enterprises are improved. The defoaming structure is simple, easy to install, good in defoaming effect and suitable for popularization, and good economic benefits are generated.
