<p>PURPOSE:To treat the dirty water containing no solid matter without power expense, by shaking the surface of water sending the air in atmospheric exposure vessel neighboring separator and providing with the sieve supported on floating element floating on the surface of water from the exposure vessel to the upper opening part of the separator slanting downward. CONSTITUTION:Solid-liquid separator 2 is provided neighboring the atmospheric exposure vessel 1 and the surface of water is shaked always by sending in the air by the gas dispersion tube, rotating disk etc. The comb teeth-shaped sieve 3 is equipped from the vessel 1 to the upper opening part of the separator 2 slanting downward. The upper end part of the sieve 3 is rotatively supported by the rotative supporting lever 31 and the lower end part of the sieve 3 is supported by the floating element 32 floating in the vessel 1 and then, the sieve 3 is shaked up and down corresponding to the shaking of the water surface. Only dirty water flowed from introducing tube opened on the upper end part of the sieve 3, is entered in the vessel 2 flowing over the sieve 3 and remaining the solid matter on the sieve and then, exposure treatment is carried out effectively.</p> |
