Explain how three different types of polyaluminum chloride how to use reasonable to explain how three different types of polyaluminum chloride how to make rational use of the current domestic market polyaluminum chloride is divided into three kinds, the first is the industrial wastewater Aluminum chloride for treatment; polyaluminum chloride for sewage treatment, and the other is potable water polyaluminum chloride; the third is white polyaluminum chloride, and the other is food grade white polyaluminum chloride Several different quality of aluminum chloride to meet the different needs of different users, today's filter water purification mainly about PAC can be applied to those industrial wastewater treatment. In many sewage polluting aluminum chloride is a very wide range of applications, is currently the mainstream of water treatment agents, with the rapid development of industry, the rapid increase in the type and quantity of waste water, water pollution is also increasingly widespread and serious In many of the sewage without effective treatment will threaten human health and safety. According to the general situation of domestic industrial wastewater can be divided into three types: The first is classified according to the products and processing targets of industrial enterprises, such as metallurgical wastewater, papermaking wastewater, coking coal gas wastewater, metal pickling wastewater, chemical fertilizer wastewater, textile printing and dyeing Wastewater, dye wastewater, tannery wastewater, pesticide wastewater, power plant wastewater. The second is based on the main components of the pollutants contained in the wastewater classification, such as acid wastewater, alkaline wastewater, cyanide-containing wastewater, chromium-containing wastewater, cadmium-containing wastewater, mercury-containing wastewater, phenol wastewater, aldehyde wastewater, , Sulfur-containing wastewater, organic phosphorus-containing wastewater and radioactive waste water. The third is based on the chemical properties of the major pollutants contained in industrial wastewater, inorganic pollutants, mainly inorganic wastewater, organic pollutants, including organic wastewater. For example, electroplating wastewater and mineral processing wastewater, is inorganic wastewater; food or oil processing wastewater, is organic wastewater. The first and third taxonomy does not cover the major components of the contaminants contained in the wastewater nor does it indicate the hazardous nature of the wastewater. The first classification, clearly pointed out that the composition of the main pollutants in the wastewater, can indicate the harmfulness of the wastewater. Wastewater treatment can be divided into three levels (again no longer specifically) Polyaluminium chloride in industrial wastewater treatment belongs to three levels, mainly refractory organic matter, phosphorus, nitrogen and other nutrients further processing, play a mixed The role of coagulation sediment, that is, the impurities in the sewage through the PAC to make it into a large floc, and then settling down. In water treatment is an indispensable step. Our task is to make three levels of PAC used, how to play its role more efficiently, there are many types of sewage, sewage treatment to each of the same kind of polyaluminum chloride treatment is effective Impossible, we must do a small test based on the actual situation.
