Description

Technical Field [0001] The present invention relates to a simultaneous treatment of floating sludge and settling sludge,

More particularly, the present invention relates to an apparatus for simultaneous treatment of floating sludge and sedimentation sludge, and more particularly, to an apparatus for collecting floating sludge and sedimentation sludge which are floated, The present invention relates to a simultaneous treatment apparatus for floating sludge and sedimentation sludge, which can efficiently treat floating sludge and settling sludge, thereby reducing maintenance cost and processing time.

Generally, in the water treatment process by the dissolved air floating (DAF) method, the flocculant is firstly flocculated in the water by using the flocculant, the floc is formed by flocculating suspended particles by the charge of the particles, A flotation tank for floating the flot to the upper surface by the air bubbles generated from the bubbler, a device for removing the flotage from the flotation tank, that is, .

In the floatation method (flotation method) in which the floating material in the water is flocculated, the small air bubbles are generated and injected into the solid mass formed in the shear flocculation reaction tank, that is, the flotation Is raised by light bubble buoyancy. The flotation method is classified into air flotation, dissolved air flotation (DAF), and vaccum flotation, among which the dissolved air flotation method is most widely used.

In the case of the air floating method, air is blown into the float tank to float solids, and it is hard to see a great effect except for the water in which the scum is well formed.

Dissolved air flotation is also a method of injecting air into a liquid at high pressure to dissolve more air and then exposing the solution to atmospheric pressure to take advantage of the synergistic effect of very small air bubbles.

The ginning process is a method of exposing a solution to a vacuum to cause the saturated air to clump with the particles and pop out with small air bubbles.

The structure of the flotation tank is generally circular and rectangular. Depending on the nature of the particles, the effect of the flotation method can be enhanced by adding coagulant or other coagulating agent.

In order to remove floating scum sludge by using various floating methods, a removing device which is rotated in the form of a flight chain is provided over the entire lengthwise direction of the float bath in the prior art, and a scum sludge It had a scraping shape.

However, in the conventional sludge removing apparatus, it is possible to remove the sludge that floats, and it is not possible to remove the settled sludge. Therefore, the sludge disposal apparatus for removing the settling sludge must be provided, There is a problem that it is cumbersome.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
