Ferrous iron is a commonly used flocculation treatment agent. It plays a flocculation treatment effect in sewage treatment. It can remove a large amount of suspended solids in sewage, remove part of it and decolorize it. Adding a certain amount of ferrous sulfide to water can adjust the value of alkaline water. The ferrous sulfide organically combines with suspended solids in the water and precipitates rapidly. Ferrous sulfide is mainly used in water purification and industrial wastewater treatment, and it also has a bactericidal effect. Ferrous sulfide anhydrate is a white powder, which turns blue-green when reacting with water. Zhengzhou Qiancheng Water Treatment Co., Ltd. is a professional manufacturer of water purification materials. Its main water purification flocculant products include ferrous sulfide, polyacrylamide, polyaluminum chloride, polyaluminum ferric chloride, polymerized ferric sulfide, etc.
Zhengzhou Qiancheng Water Treatment Company has an annual production and sales volume of 10,000 tons of ferrous sulfide, with guaranteed quality, varying contents and complete specifications.

Adding a certain amount of Qiancheng brand ferrous sulfide to the water can adjust the value of alkaline water. The ferrous sulfide organically combines with suspended solids in the water and precipitates rapidly. Main applications It is used for water purification and industrial wastewater treatment, and has a bactericidal effect. Qiancheng brand ferrous sulfide is a commonly used flocculation treatment agent, which has the effect of flocculation treatment. It can remove a large amount of suspended solids in sewage, remove part of it and decolorize it. Ferrous sulfide and ferrous sulfide heptahydrate are different crystals of ferrous sulfide. The water quality and source strength are different, the required treatment effects are different, and the dosage of chemicals is different. A small test should be done to find the best combination of dosage and treatment efficiency, which is the dosage of chemicals per ton of water. Adding ferrous sulfate to industrial wastewater that reacts with ferrous ions to form precipitates may not necessarily be suitable.

Ferrous iron
Basic properties
[Ferous sulfide] is an inorganic compound with the chemical formula of, also known as black vitriol and green vitriol. The appearance is water green Or blue-green crystal. It is a by-product produced during the production of a rare ferrous metal product through the sulfur process. Relative density melting point ℃. Odorless and astringent. It is easy to weather when exposed to the air, and the surface turns into a white powder. It is easy to oxidize in humid air and generates brown basic iron sulfide on the surface. It is soluble in water and glycerin and insoluble in alcohol. It has a reducing effect. It changes from heptahydrate to tetrahydrate at ℃. It turns into monohydrate at ℃. It loses six crystal waters at ℃. It loses all crystal water at ℃ and becomes anhydrous. Red It decomposes and releases when hot. Corrosive. Fluorescent in dry air. The anhydrous substance is white powder, which turns blue-green when reacting with water.

Main uses
Ferrous sulfide is mainly used as a flocculant, with good flocculation effect, good decolorization ability, and It has functions such as heavy metal ion removal, oil removal, phosphorus removal, and sterilization. It is especially effective in decolorizing and removing printing and dyeing wastewater and co-precipitating ferrite in electroplating wastewater. It is also cheap and is the first choice for wastewater treatment such as printing and dyeing and electroplating. product.
, Ferrous sulfide can also be used as food additives, pigments, raw materials for the electronic industry, hydrogen sulfide deodorizers, soil conditioners, industrial catalysts, etc.
, Ferrous sulfide is used as fertilizer, herbicide and pesticide in agriculture. It is mainly used to treat smut of wheat. Ferrous sulfide regulates soil pH and promotes the formation of chlorophyll (also known as iron fertilizer). It can prevent flowers and trees from iron deficiency. Caused by (yellow disease). It is an indispensable element for acid-loving flowers and trees.
Pharmaceutical application: It is used as a local astringent and blood tonic in medicine. The iron contained in it is the raw material for the synthesis of red blood cells in the body.

Notes
Since Qiancheng brand ferrous sulfide is easily soluble in water, it has certain hygroscopic properties. Stable, it is easily oxidized to brown-red iron sulfide by oxygen in the air, especially under high temperature and strong light conditions. Therefore, iron sulfide must be placed in a light-tight, airtight container and placed side by side. Storing ferrous sulfide in a cool place is an industrial by-product with wide sources and low price. It is a good source of iron in soilless cultivation. However, ferrous sulfide is easily oxidized in the nutrient solution and forms with other compounds (especially phosphates). Insoluble iron phosphate precipitates. Therefore, most of the current nutrient solution formulas do not directly use ferrous sulfide as the iron source. Instead, they use complexed iron or ferrous sulfide and a complexing agent (such as or etc.) before complexing. Only use it to ensure its effectiveness in the nutrient solution for a long time. At the same time, pay attention to the value of the nutrient solution not to be too high (.) and should be kept below. Otherwise, precipitation will occur due to the high value, causing The effectiveness of iron is reduced. If ferrous sulfate is found to be severely oxidized and its appearance changes to brownish-red, it should not be used.

Packaging, storage and transportation are lined with polyethylene plastic woven bags to prevent moisture and rain. It is strictly prohibited to store or mix with toxic and harmful substances. Ferrous sulfate is not, ferrous sulfide monohydrate is?, ferrous sulfide heptahydrate is?. Transportation precautions: The packaging should be complete and the loading should be secure at the time of shipment. During transportation, make sure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with oxidants, alkalis, food chemicals, etc.

Preservation method: Add iron and sulfur when preserving ferrous sulfide, because ferrous iron is easily oxidized by oxygen in the air. Adding some reduced iron can reduce the oxidized valence. Iron is reduced back again, and the purpose of sulfur is to provide hydrogen ions, that is, to provide an alkaline environment, which prevents the hydrolysis of ferrous sulfide from another aspect, because it is a strong acid and weak salt, which is easy to hydrolyze, while iron and sulfur The reaction is very slow ~ and even if it reacts, ferrous sulfide will be produced and no impurities will be produced.
