Using coagulant polyferric sulfate on steel wastewater treatment effect? Using coagulant polyferric sulfate on steel wastewater treatment effect? The origins of steel waste water are mainly the waste water produced in its production technology, the waste water discharged from the steel making process and the cooling waste water after the steel products, as well as the gas waste water in the steel refining process. This is a lot of pollutants and suspended solids. Due to different refining methods of steel, the nature of the wastewater is also different, generally containing acid wastewater, alkali-containing wastewater, oil-containing wastewater (a lot of waste oil cooling products), the pollutants are generally rich in a lot of heavy metal ions and suspended solids The general hardness of steel wastewater is high, high color. Iron and steel gas wastewater suspended solids content can reach 1000 ~ 3000mg / L, its treatment methods are generally coagulation and sedimentation method so that the pollutants and suspended solids removed. The coagulation deposition process is the best choice of pharmaceutical polymerization of ferric sulfate + lime flocculation deposition method for processing. Lime can neutralize acid wastewater and can perform secondary coagulation and sedimentation on the suspended wastewater of the wastewater after being treated with the polymerized ferric sulfate. Polymeric ferric sulfate treatment Establish a sound and reasonable water-saving engineering system and statistical indicator system: steel enterprises should set up special management departments of water resources, establish the work objective is to control water and improve water use efficiency, the specific measures and methods . Polymeric ferric sulfate treatment managers first grasp the current water (metering timely, accurate, stable, the process and water consumption, but also the most important issue, the key to the polymerization of ferric sulfate treatment enterprises, and so on), and then Considered the company to further water conservation, direction and goals, there are measures. Enterprise water management advanced, water budget, not counting. Steel enterprises to build the statistical indicators of the system, polymerization of ferric sulfate treatment to promote the development of water-saving work. The general classification of water for iron and steel enterprises: cooling water, process water, polyferric sulfate treatment water, water boilers and other water should include comprehensive indicators: polyferric sulfate treatment from the water production value of 10,000 yuan, tons of water, the total water consumption per ton of steel , The unit of domestic water consumption, reuse of water. The water use index should include: the total production of water, repeated water, total water intake, indirect cooling water, polymeric ferric sulfate treatment of water, cooling water and water directly filled, the process and its water, water consumption And water boiler life as well as other water consumption, water consumption. Reuse indicators include: indirect cooling water recycling rate and the process of water reuse, boiler water reuse, steam condensate treatment.
