Description
Technical Field
The invention belongs to the technical field of wastewater treatment, and particularly relates to a simple physical defoaming method.
Background
More industrial wastewater contains impurities such as surfactant and the like, more foam is generated in the treatment process of a wastewater station, for example, more foam is easily generated in the processes of stirring, pressurizing, pumping and falling impact of wastewater, if the foam is not timely removed, the accumulated foam overflows from a pool to pollute the land, or enters a municipal sewage pipe network along with the drainage, and the foam has the risk of overflowing a sewage well in the process of flowing through the municipal pipe network. How to reduce the cost and achieve the goal of defoaming is the subject of research, so a defoaming method needs to be designed to solve the current problems.
Disclosure of Invention
In view of the problems raised by the above background art, the present invention is directed to: aims to provide a simple physical defoaming method.
In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:
a simple physical defoaming method comprises the steps of connecting waste water with foam, which reaches the standard in waste water station treatment, into a plastic barrel through a liquid inlet pipe, connecting the liquid inlet pipe into the plastic barrel from the side surface of the upper end of the plastic barrel, separating waste water mixture with foam in the plastic barrel, connecting the foam at the upper end of the plastic barrel, connecting water at the lower end of the plastic barrel, discharging the foam from a foam discharge pipe connected to the upper end of the plastic barrel, discharging the foam to an adjusting tank for natural defoaming, discharging the waste water without foam from a liquid discharge pipe connected to the lower end of the plastic barrel, and connecting the waste water discharged from the liquid discharge pipe into a drainage channel of a sewage station for discharge.
In a preferred embodiment of the present invention, the drain pipe is directed upward at the outlet of the drainage channel of the sewage station without exposing the liquid surface.
In a preferred embodiment of the present invention, the drain pipe has a shape of a smooth right-angled elbow at a corner.
As a preferred scheme of the invention, the diameter of the foam discharging pipe is not less than 5cm, so that the foam is discharged in time.
As a preferable aspect of the present invention, the drain pipe is bent upward by a certain height; therefore, a certain liquid level can be ensured in the plastic barrel, and the foam is prevented from entering the liquid discharge pipe.
The invention has the beneficial effects that:
1. according to the invention, defoaming can be realized without adding a defoaming agent, so that the defoaming cost is reduced, and the economic benefit of an enterprise is improved;
2. the defoaming device has the advantages of simple structure, easy installation, good defoaming effect, suitability for popularization and better economic benefit.
Drawings
The invention is further illustrated by the non-limiting examples given in the accompanying drawings;
FIG. 1 is a schematic structural diagram of a simple physical defoaming method according to an embodiment of the present invention;
the main element symbols are as follows:
the device comprises a liquid inlet pipe 1, a foam discharging pipe 2, a plastic barrel 3, a liquid discharging pipe 4 and a drainage channel 5 of a sewage station.
Detailed Description
In order that those skilled in the art can better understand the present invention, the following technical solutions are further described with reference to the accompanying drawings and examples.
As shown in figure 1, the simple physical defoaming method comprises the steps of enabling waste water with foam, which reaches the standard in waste water station treatment, to be connected into a plastic barrel 3 through a liquid inlet pipe 1, enabling the liquid inlet pipe 1 to be connected into the plastic barrel 3 from the side surface of the upper end of the plastic barrel, enabling a waste water mixture with foam to be separated in the plastic barrel 3, enabling the foam to be arranged at the upper end of the plastic barrel 3, enabling water to be arranged at the lower end of the plastic barrel 3, enabling the foam to be discharged from a foam discharge pipe 2 connected to the upper end of the plastic barrel 3, discharging the foam to a regulating tank for natural defoaming, enabling waste water without foam to be discharged from a liquid discharge pipe 4 connected to the lower end of the plastic barrel 3, and enabling waste water discharged from the liquid discharge pipe 4 to be connected into a waste water station drainage channel 5 for discharging.
The invention carries out defoaming, can efficiently solve the problem of much foam in the sewage station with less investment, does not generate cost in the operation process, greatly reduces the medicament cost of the sewage station and saves the operation cost.
Wherein the drain pipe 4 is upward at the outlet of the drainage channel 5 of the sewage station and does not expose the liquid level. This prevents re-foaming at the outlet end.
Wherein, the liquid discharge pipe 4 is in the shape of a smooth right-angle elbow at the corner. Therefore, the impact of the process that the waste water flows through the sewage station drainage channel 5 from the plastic barrel 3 after the foam-water separation can be reduced, and the secondary foam generation is prevented.
The pipe diameter of the foam discharging pipe 2 is not less than 5cm, so that the foam can be discharged in time.
Wherein the drain pipe 4 is bent upwards at a certain height; this ensures that a certain level of liquid is maintained in the plastic tub 3, preventing foam from entering the drain pipe 4.
The foregoing embodiments are merely illustrative of the principles of the present invention and its efficacy, and are not to be construed as limiting the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
