Polyferric sulfate plays an important role in urban sewage treatment, mainly manifested in the following aspects:
Firstly, polymeric iron sulfate can effectively remove suspended and precipitated substances in wastewater, reduce the concentration of suspended substances, and improve water quality. These suspended solids and sediments may include harmful substances such as sediment, organic matter, heavy metal ions, etc. By using polymeric iron sulfate, the appearance and odor of urban sewage can be significantly improved, and its transparency and biodegradability can be enhanced.
Secondly, polymeric iron sulfate has a good denitrification and phosphorus removal effect. In the process of wastewater treatment, polymeric iron sulfate can remove nutrients such as nitrogen and phosphorus from wastewater, thereby reducing the risk of eutrophication in water bodies. This is of great significance for controlling the growth of algae in water bodies and maintaining water quality health.
In addition, polymeric iron sulfate also has functions such as fluorine removal, oil removal, and decolorization. It can remove fluoride ions, oil substances, and colored substances from wastewater, further improving water quality.
Polyferric sulfate has also been widely used in the primary and secondary treatment of urban sewage treatment plants. In primary treatment, it can remove large suspended particles in wastewater, reducing the burden on subsequent treatment facilities. In secondary treatment, polymeric iron sulfate can further remove organic matter and phosphates from wastewater, improving water quality.
In summary, polymeric iron sulfate has played an important role in urban sewage treatment and has made positive contributions to improving the urban water environment. By using polymeric iron sulfate, the treatment efficiency of urban sewage can be effectively improved, ensuring people's health and quality of life, while also making important contributions to environmental protection.
