With the rapid development of urbanization, garbage disposal has become an important issue of environmental protection, and garbage water treatment is a key link. In the process of garbage water treatment, the generation of foam is a common and thorny problem. It will increase the surface tension of water, hinder the dissolution of oxygen, affect the activity of aerobic microorganisms, and thus reduce the treatment efficiency. In order to solve the problem of bubbles, garbage water treatment defoamers came into being.
Garbage water treatment defoamers
Working principle of garbage water treatment defoamers
Garbage water treatment defoamers are a chemical additive specially used to control and eliminate foam. They are composed of a variety of active ingredients. Their main function is to quickly break the foam and inhibit its regeneration by reducing the gas-liquid surface tension and destroying the foam structure. In the process of garbage water treatment, the application of defoamers is of great significance.
Characteristics of garbage water treatment defoamers
Garbage water treatment defoamers have the following significant characteristics:
Rapid defoaming and long-lasting foam suppression: Defoamers can quickly eliminate foam in a short time and maintain a long-term foam suppression effect.
Strong chemical stability: Defoamers are chemically stable and not easy to react with other substances in wastewater.
Wide range of applications: Garbage water treatment defoamers are not only suitable for garbage leachate, but also can be used for wastewater treatment in papermaking, pharmaceuticals, printing and dyeing, chemicals and other industries.
Environmental protection and safety: It adopts an environmentally friendly formula, does not contain harmful substances, and will not cause secondary pollution to microorganisms or the environment.
The role of garbage water treatment defoamers
The role of garbage water treatment defoamers is mainly reflected in improving treatment efficiency, improving treatment water quality and reducing treatment costs. First, defoamers can reduce foam generation and make the treatment process smoother. Secondly, it can also increase the concentration of activated sludge, thereby improving water quality. In addition, the use of defoamers can also reduce energy consumption, reduce the use of agents, and further reduce treatment costs.
Selection and use of garbage water treatment defoamers
When selecting garbage water treatment defoamers, it is necessary to select the appropriate type of defoamer according to the specific process flow and water quality. For example: polyether defoamers are suitable for wastewater treatment in strong acid and alkali systems, while high carbon alcohol defoamers have poor flow properties at low temperatures and may need to be used under specific conditions.
The method of using the defoamer for garbage water treatment is very simple. Generally speaking, the amount of defoamer added is 0.1%~0.3%. The specific amount needs to be determined based on the test. When using, the defoamer can be directly added or sprayed into the medium to be treated, or it can be diluted in a certain proportion before use.
