Application of polyferric sulfate in industrial wastewater

When polyferric sulfate is used in the treatment of rare earth industrial wastewater: for example, the device keeps a certain distance between the surface of small solid particles and high concentration ion membrane of wastewater, greatly reduces harmful substances and membrane surface, and has the opportunity to avoid pollution on the membrane surface. polyferric sulfate improves the excessive circulation of water; This process not only separates and enriches ammonium chloride with high concentration in rare earth extraction process wastewater, recovers waste water after rare earth industry standards, and reduces the recovery of raw materials for rare earth industry production through electrolytic process and solar energy for a successful recovery of hydrochloric acid and ammonia reactor, polyferric sulfate, but also uses fuel cells to recover energy, added, The cost of treating a large amount of waste water is 40 yuan, 1600 tons / day, including 100g / L ammonium chloride. Through this process, the first generation of hydrochloric acid and ammonia water can achieve a profit of 110000 yuan, which is not only the goal of reduction, stability and harmlessness for the country's sewage treatment and disposal; Strictly control the content of heavy metals and toxic and polymeric ferric sulfate harmful substances in rare earth industrial wastewater; On the premise of safety, environmental protection and economic recovery, use the energy and resources of wastewater and polymeric ferric sulfate waste gas to achieve the purpose of wastewater and waste gas treatment and comprehensive utilization, energy conservation and emission reduction and the development of circular economy.

Applications of polymeric ferric sulfate include:

1. Printing and dyeing wastewater treatment can replace the traditional coagulant of low molecular iron salt and aluminum salt. Compared with the characteristics of large dosage of traditional coagulant, low coagulation efficiency and aluminum ion residue, it is easy to cause secondary pollution. The dosage of polymeric ferric sulfate is about 150ppm, the dosage is small, the removal rate of COD and chromaticity is high, and the optimal pH condition is 8.0. 

2. Electroplating wastewater treatment can be used as coagulant and complexing agent. The complex is mainly copper ammonia complex, which has stable properties and pH = 11. It is difficult to precipitate directly with alkali, polyaluminium and other coagulants. It can also be used as reclaimed water reuse.

3. For papermaking wastewater treatment, instead of polyaluminium chloride and aluminum sulfate, it can be used as coagulant and dewatering of papermaking sludge. In the white water recovery process of papermaking wastewater treatment, polymeric ferric sulfate (polymer containing strong cations) can not be used, but polyaluminium chloride can only be used.

Polyferric sulfate uses the combination of dielectric electrophoresis technology and osmotic membrane separation technology to reuse sewage, realize technological innovation and scientific and technological progress of wastewater treatment, give full play to the investment and operation efficiency of equipment, which is suitable for China's national conditions and conforms to the characteristics of new wastewater treatment technology, polyferric sulfate technology and equipment in Inner Mongolia Autonomous Region. If the new technology is widely used, it will improve the treatment and disposal level of industrial wastewater of mining enterprises in this area, further protect and improve the ecological environment, and promote the sustainable development of our economy, society and environment in this area.
