During the production process of textile fabric factories, a large amount of sewage is generated. These sewage contains various organic and inorganic pollutants, among which color is a more prominent problem. The color of sewage not only affects the beauty of the environment, but may also cause harm to the ecosystem. Therefore, an effective sewage decolorizer is essential for textile fabric factories.
Sewage decolorizer is a chemical agent specially used to remove the color of sewage. It achieves the effect of decolorization and meets the discharge standards by chemically reacting with the pigment molecules in the sewage, decomposing or converting them into colorless substances.
When choosing a sewage decolorizer, the following factors need to be considered:
1. Decolorization effect: The main function of the decolorizer is to remove the color of sewage, so the decolorization effect is the primary factor of selection. It is necessary to select a decolorizer that can effectively remove the color of sewage to meet the discharge standards.
2. Scope of application: Different sewage decolorizers are suitable for different types of sewage, and it is necessary to select a suitable decolorizer according to the characteristics of the sewage in the textile fabric factory. For example, some decolorizers are suitable for treating sewage containing organic pigments, while others are suitable for treating sewage containing inorganic pigments.
3. Cost: The cost of sewage decolorizer is also an important factor in selection. It is necessary to choose a decolorizer with reasonable price and high cost performance to reduce the cost of sewage treatment.
4. Safety: Sewage decolorizer may cause certain harm to the environment and human body during use, so it is necessary to choose a decolorizer with high safety and environmental protection.
When using sewage decolorizer, you need to pay attention to the following points:
1. Correct use: When using sewage decolorizer, you need to use it correctly according to the instructions to avoid improper use resulting in poor decolorization effect or harm to the environment.
2. Reasonable dosage: The dosage of sewage decolorizer needs to be adjusted according to the specific situation of sewage. Too little dosage may lead to poor decolorization effect, and too much dosage may cause waste and pollution to the environment.
3. Reaction time: It takes a certain amount of time for sewage decolorizer to react chemically with pigment molecules in sewage, so it is necessary to control the reaction time to ensure the decolorization effect.
4. Subsequent treatment: Sewage treated with sewage decolorizer may also need subsequent treatment, such as sedimentation, filtration, etc., to ensure that it meets the discharge standards.
In short, sewage decolorizer is an effective way to solve the problem of sewage color in textile fabric factories. When selecting and using sewage decolorizers, it is necessary to comprehensively consider factors such as decolorization effect, scope of application, cost and safety to ensure sewage treatment effect and environmental safety.
