Description

Air-float purifying equipment
Technical Field
The utility model belongs to the technical field of industrial sewage treatment technique and specifically relates to an air supporting clarification plant is related to.
Background
The air-float purifying equipment is a water treatment equipment which can make air pass through or produce lots of fine bubbles in water to make air be attached to suspended particles in the form of high-dispersion fine bubbles to make the density be less than that of water, and utilize buoyancy principle to make it float on the water surface, and the suspended particles are accumulated to form lots of floating slags to float on the water surface, then the floating slags are removed by foam-scraping machine so as to implement solid-liquid separation. The air-flotation purification device is particularly suitable for the separation of very fine particles with a particle density close to or less than 1. The scum of the air floatation purifying equipment can not be scraped completely by the scum scraping machine, the scum remaining on the water surface sinks to the bottom of the scum separation area along with the breaking of bubbles, and the sunk scum is sucked by the water collecting pipe at the bottom of the scum separation area along with the fluctuation of water flow and is discharged into the clear water area, so that the water is discharged with the sludge. The phenomenon is particularly remarkable on small-water-volume air-floating purification equipment, and directly influences the quality of effluent and the standard discharge effect.
In view of the above-mentioned phenomena, it is a common practice to arrange a conical hopper at the bottom of the scum separation area and periodically discharge the residual sludge; secondly, the container pump and the slag scraping device are closed in a delayed mode after the sewage inlet pipe is closed, and scum on the surface is scraped to the maximum extent; thirdly, when the mud is discharged, the machine is stopped to empty the separation area and the clean water area, and clean tap water is refilled. The first method works well, but increases the complexity and cost of the equipment; the second method only relatively prolongs the effective running time and does not thoroughly solve the problem; the third method, though thorough, is not controllable and wastes water resources, increasing operating costs.
