Brief description of organic sulfur products
Organic sulfur is used for wastewater treatment in wet desulfurization of flue gas in power plants.
Metals are essential in many production processes, but their use generates wastewater containing heavy metals. Chemical precipitation is usually used, and chemical precipitants such as sodium hydroxide or calcium hydroxide are added during the neutralization process to precipitate heavy metal ions. However, when the wastewater contains a complexing agent, the complexing agent keeps the heavy metals in a dissolved state and cannot form hydroxide precipitation. The concentration of residual heavy metals is high and cannot meet environmental protection requirements.
Organic sulfur can react quickly with heavy metal ions in wastewater at room temperature to form water-insoluble salts. Add a small amount of flocculant to form a flocculent precipitation to remove heavy metals. It has been proven by use that the treatment method is simple and can meet environmental protection requirements after one treatment when multiple heavy metal ions coexist. It can also fully play its role in heavy metal complex salts in waste water, and has the characteristics of coarse flocculation, fast precipitation, and post-treatment It is easy, stable, non-toxic, and has no secondary pollution. It can be widely used in various wastewater treatment.
Product Features
Organic sulfur is highly safe. It is non-toxic, harmless to the environment, has no unpleasant odor, and does not produce toxic substances when precipitating metal, so it can be used with confidence.
Good organic sulfur removal effect. Organic sulfur is effective in a wide range of values and can be used to treat acidic and alkaline wastewater. It can achieve removal effects regardless of the concentration of heavy metal ions in the wastewater. When multiple metal ions coexist, they can also be removed at the same time. When heavy metal ions exist in the form of complex salts (tetraamine, etc.) and cannot be completely removed by hydroxide precipitation, organic sulfur can play a good removal role. Organic sulfur is not affected by the coexisting salts in the waste liquid when precipitating heavy metals.
The organic sulfur flocculation effect is good. The metal precipitate is a coarse floc, which settles quickly and is easy to separate solid and liquid.
Organic sulfur precipitates are stable. The metal precipitate is very stable and will not release heavy metals even at -℃ high temperatures. The precipitate will not leak out in dilute acid solution, causing no secondary pollution and is safe to dispose of.
The treatment method is simple and the sludge is easy to dewater.
Typical indicators
Appearance of organic sulfur: colorless or light yellow transparent liquid
Odor: slight
Value:
Specific gravity:
This is a typical property of organic sulfur , but should not be considered as a product supply indicator.
Application and Dosage
Before actual use of organic sulfur, a small-scale test of - can be done according to the following process.
When treating wastewater, adjust the value between - for the best effect.
Determine the amount of organic sulfur based on the content of heavy metal ions in the wastewater.
It can be added to the waste water continuously or in batches, and stir thoroughly for about 3 minutes.
Add an appropriate amount of organic flocculant, which can be non-ionic, strong cationic or strong anionic. Stir quickly and then slowly.
The metal-organic sulfur precipitates are separated by filtration, and the filtered water is qualified water.
Packaging and Storage
Organic sulfur is packed in plastic drums or barrels, or can be packaged according to customer requirements. The product shelf life is months.
Safety and Protection
Pay attention to labor protection when operating organic sulfur. Avoid contact with skin, eyes, etc., and rinse with plenty of water after contact.
