Circulating water treatment is a very important environmental protection work, which aims to purify and improve water quality by removing various pollutants from water through a series of treatment processes. Activated carbon is a very important treatment material in the process of circulating water treatment, which has the characteristics of strong adsorption capacity, large surface area and good stability, and plays an important role in sewage treatment and water quality improvement.
First, let's take a look at the performance parameters of activated carbon. Its performance parameters include appearance, specific surface area, porosity, pH. , saturation adsorption, etc. In appearance, high-quality activated carbon particles should be black, uniform and smooth particles, without foreign matter mixing. Specific surface area is an important indicator of activated carbon. The adsorption capacity of activated carbon is usually evaluated in terms of specific surface area. The larger the specific surface area, the better the adsorption performance of activated carbon. Porosity refers to the ratio of micropores and mesopores inside activated carbon. The higher the porosity, the stronger the adsorption capacity of the activated carbon. The pH value can reflect the acidity and alkalinity of activated carbon. Generally speaking, activated carbon with a pH value between 6-8 is more suitable for recycled water treatment. Saturation adsorption capacity refers to the saturation adsorption capacity of activated carbon.
In practical application, it is very important to choose the appropriate activated carbon according to the specific situation of circulating water treatment and the types of pollutants that need to be treated. Generally speaking, for the removal of organic matter, we can choose hydrophobic activated carbon, and for the removal of inorganic matter, we need to choose hydrophilic activated carbon. In addition, in order to obtain the best treatment results, the particle size of the activated carbon and the choice of additives need to be considered.
The use and management of activated carbon is also important in addition to choosing the right activated carbon. When using activated carbon for circulating water treatment, saturated adsorbents need to be added first to ensure the adsorption capacity of activated carbon. At the same time, the performance parameters of activated carbon need to be tested and monitored regularly. Once the adsorption capacity is reduced or saturated, the activated carbon needs to be replaced or regenerated. In addition, in order to ensure the adsorption effect of activated carbon, it is also necessary to reasonably configure the feeding amount and feeding position of activated carbon.
To sum up, activated carbon plays a very important role in circulating water treatment. Choosing the right activated carbon, rational use and management of activated carbon can effectively improve the quality of circulating water and reduce water pollution. Therefore, in the process of circulating water treatment, it is necessary to pay attention to the performance parameters of activated carbon, choose the activated carbon that suits your needs, and regularly test and manage the adsorption performance of activated carbon to ensure the best treatment effect.
