Air float basic introduction

Summary of information:

An air float is a device that uses tiny bubbles to surface impurities (SS) in the medium。For the sewage containing some fine particles whose specific gravity is close to that of water and their own weight is difficult to sink or float, it can be treated with an air flotation device。Pre-treated sewage, except for some raw water bodies containing more sand and sewage containing heavy mechanical impurities, most of them are light suspended particles。For example, algae in rivers and lakes, reservoirs and some rivers;Plant residues and fine colloidal impurities;Printing and dyeing industry...

An air float is a device that uses tiny bubbles to surface impurities (SS) in the medium。It can be used for sewage containing some fine particles whose specific gravity is close to that of water and whose own weight is difficult to sink or rise气浮Device handling。
Pre-treated sewage, except for some raw water bodies containing more sand and sewage containing heavy mechanical impurities, most of them are light suspended particles。For example, algae in rivers and lakes, reservoirs and some rivers;Plant residues and fine colloidal impurities;Dye particles in printing and dyeing industry;Short fiber in papermaking and chemical fiber industry;Oil refining,Chemical industryDroplets of petroleum and organic solvents;electrosumPickling wastewater中的Heavy metal离子;Electrophoretic paintWaste water, etc.;Light particles with a specific gravity very close to that of water。For these raw water, if the traditional precipitation method is used, the effect is bound to be poor, especially in the low temperature conditions in winter, due to the deterioration of coagulation and hydraulic conditions, the treatment effect is more difficult to ensure。It can be imagined that it is difficult to precipitate the floc, forcing it to sink is bound to get half the result with twice the effort, so it is better to take advantage of the situation and artificially introduce bubbles into the water body to make it粘附On the floc, the overall density of the floc is greatly reduced, and by the rising speed of the bubble, it is forced to float, so as to achieve rapid solid-liquid separation。In that sense,气浮The advent of technology, yesGravitational settlementIt has opened up a new field of solid and liquid separation technology。
