This product can be added directly, or the dissolved tank is added first, the concentration is 10 to 20%, stirred, and the pump is added to the reaction tank. This product has a wide range of pH, which is more effective under acidic conditions, which is about 100 ~ 1000ppm (ie 0.1 ~ 1 kg / ton wastewater), which is different depending on the amount of phosphate in wastewater. The specific amount is generally determined by experiments

Features of polyferric sulfate: Polyferric sulfate is divided into solid and liquid, the liquid is a reddish-brown viscous liquid; the solid is a red or light yellow granular substance that is easily soluble in water. Its main feature is that a large number of polynuclear complexes such as [Fe4(H2O)6], [Fe2(H2O)6], [Fe(OH)2] are produced after the hydrolysis of polymerized ferric sulfate. It can make the colloidal particles in the water agglomerate together. At the same time, a series of physical and chemical changes occurred, which made them have strong electrical neutralization ability, thereby reducing the potential of the micelles, breaking the stability of the micelles, and promoting the rapid aggregation and precipitation of the micelles; Due to the low alkalinity degree of polyferric sulfate (10%-13%), compared with polyaluminum chloride, polyaluminum has greater cohesion; the resulting flocs are larger and settle faster. In addition, the relative density is small, and the application effect is better in air flotation; the pH value is suitable for light (4-11), except for Mn, it has a good removal effect on other heavy metals; SS, COD, BOD, chromaticity and odor, etc. have good removal effect; with a certain amount of coagulant polyacrylamide precipitation effect is better; has demulsification function, so it has a certain effect on the removal of emulsified oil; simple to manufacture, low price of raw materials, easy to obtain, Corrosiveness is small; the dosage of chemicals is small, and the amount of sludge generated is smaller than that of other chemicals.
A certain amount of raw water is taken to add an appropriate amount of this product (such as 500 ppm) to adjust the pH of the wastewater to 7 to 8, and a small amount of polyacrylamide PAM flocculation precipitate is added, and the supernatant is filtered to determine the content of phosphorus. (To handle heavy metals, use the supernatant to carry out the secondary processing.)
1. The treatment of printing and dyeing wastewater can replace the traditional coagulants of low molecular weight iron salts and aluminum salts. Compared with the traditional coagulants, the amount of coagulants is large, the coagulation efficiency is low, and the residues such as aluminum ions are easy to cause secondary pollution. The dosage is about 150ppm, the dosage is small, the removal rate of COD and chroma is high, and the optimal pH value condition is: 8.0.
2. Electroplating sewage treatment, can be used as coagulant and breaker. The complex is mainly copper-ammonia complex, which is stable in nature, pH=11, and is difficult to directly precipitate with alkali, polyaluminum and other coagulants. It can also be used for reuse of reclaimed water.
3. Papermaking wastewater treatment, instead of polyaluminum chloride, aluminum sulfate, etc., can be used as a coagulant, and can also be used for papermaking sludge dewatering. polymer), only polyaluminum chloride can be used.
Flocculation technology is widely used in the treatment of oily wastewater due to its strong adaptability, the ability to remove emulsified oil and dissolved oil, and some complex macromolecular organic compounds that are difficult to biochemically degrade. Commonly used flocculants are mainly inorganic flocculants, organic flocculants and composite flocculants.
Among the inorganic macromolecule flocculants, polyaluminum chloride, polyferric sulfate and other lower molecular weight inorganic flocculants have good treatment effect, low price, low dosage, high efficiency and are widely used.
