Nowadays, environmental pollution is quite serious, so in the process of treating sewage, attention should also be paid to each link. Nowadays, in the process of treating sewage, the selection of materials is always emphasized. Some people choose calcium hydroxide, while others use calcium oxide. So, which one should be chosen in the sewage treatment process?
Is calcium hydroxide or calcium oxide used for sewage treatment
In fact, there is no difference between the two. The main component of quicklime is calcium oxide, which is a white solid with fire-resistant effect. If limestone with a high content is burned directly to 900 degrees in a ventilated place, it can be obtained. Hydrated limestone is a product formed by adding quicklime to water. In the process of treating sewage, the two have the same composition, so the effect is the same.
What are the functions in the process of treating sewage
Why are these two materials used in the process of treating wastewater? The main reason is to effectively remove silver phosphate, which is a strong alkaline agent that can effectively neutralize acidic wastewater and heavy metal wastewater. By adjusting the pH value, the demulsification effect can be achieved, and harmful substances in the flue gas can be absorbed, so that the emission of flue gas can effectively meet environmental standards. Although the composition of these two materials is the same, there are some differences in their effects during use. They are both used to regulate wastewater, but there are some differences.
What are the differences when treating wastewater?
Calcium hydroxide is prone to generate a large amount of heat when treating wastewater. If temperature needs to be considered, it is recommended not to choose calcium hydroxide, but to choose calcium oxide directly. Lime is relatively convenient for storage and transportation. If you want to use the same quality for water treatment, it is recommended to choose calcium hydroxide directly. If we look at pH adjustment, calcium oxide is obviously more effective than calcium hydroxide. Looking at their appearance, there is no difference between the two. However, after quicklime becomes mature, the impurities it contains will also increase the content of sludge, which will affect the treatment effect of water pollution.
How to choose between the two should be based on the actual situation of the factory. It is best to mix the two together in order to bring better results and meet the needs of each link.
