Polymerized Ferrous Sulfate Solution 38%

Polyferric sulfate is an inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and is easily soluble in water. A 10% (mass) aqueous solution is a reddish-brown transparent solution and is hygroscopic. Polyferric sulfate is widely used in the purification treatment of drinking water, industrial water, various industrial wastewaters, urban sewage, sludge dehydration, etc.

A. Polyferric sulfate in rare earth industrial wastewater treatment: For example, the device keeps the tiny solid particles of the wastewater and the high-concentration ion membrane surface at a certain distance, greatly reducing harmful substances and giving the membrane surface a chance to avoid contamination on the membrane surface. Polymeric ferric sulfate improves water circulation; this process not only separates high-concentration wastewater from the rare earth extraction process with enriched ammonium chloride, recovers wastewater after the rare earth industry standard, but also produces hydrochloric acid and ammonia through an electrolysis process and solar energy The recovery of reactors, the recycling of raw materials for polyferric sulfate production in the rare earth industry, and the energy recovery through the use of fuel cells also add that the cost of processing a large amount of waste water is 40 yuan, which is 1,600 tons/day, including 100g/L Calculating ammonium chloride, through this process, the generation of hydrochloric acid and ammonia water can achieve a profit of 110,000 yuan, which not only achieves the goal of reduction, stability and harmlessness of the country's sewage treatment and disposal; it also strictly controls the rare earth industrial wastewater The content of heavy metals and toxic, polymerized ferric sulfate harmful substances; on the premise of safety, environmental protection and economic recovery, use the energy and resources of wastewater and polymerized ferric sulfate waste gas to achieve wastewater and waste gas treatment and comprehensive utilization, energy conservation and emission reduction, and realize recycling the purpose of economic development.
Polyferric sulfate uses a method that combines dielectric electrophoresis technology and permeable membrane separation technology to recycle sewage, achieve technological innovation and technological progress in wastewater treatment, and give full play to the investment and operating efficiency of equipment. It is suitable for China's national conditions and in line with the characteristics of the Inner Mongolia Autonomous Region. New technologies for wastewater treatment, new technologies for polyferric sulfate and new equipment. If the new technology is widely used, it will improve the treatment and disposal level of industrial wastewater from mining companies in the region. Polyferric sulfate will further protect and improve the ecological environment and promote the sustainable development of our economy, society and environment in the region.
B. Industrial wastewater treatment
1. Printing and dyeing wastewater treatment, replacing traditional low-molecular iron salts and aluminum salts as coagulants. Compared with traditional coagulants, they use large amounts, have low coagulation efficiency, and have aluminum ions and other residues that can easily cause secondary pollution. Polymeric ferric sulfate has the characteristics of The dosage is about 150ppm, which is a small amount and has a high removal rate of COD and chroma. The optimal ph value condition is: 8.0.
2. For electroplating wastewater treatment, it can be used as coagulant and complexing agent. The complex is mainly a copper-ammonium complex, which is stable in nature and has a pH of 11. It is difficult to directly react with coagulants such as alkali and polyaluminum to precipitate. It can also be used for reclaimed water reuse.
3. Papermaking wastewater treatment, replacing polyaluminium chloride, aluminum sulfate, etc., as coagulant, and can also be used for papermaking sludge dehydration. Polyferric sulfate (containing strong cations) cannot be used in the white water recovery process of papermaking wastewater treatment. polymer), only polyaluminum chloride can be used.
