Abstract
PURPOSE:To decompose silt, etc., deposited in the river, etc., at a high speed, to purify the water-area environment, and to prevent the secondary environmental pollution due to the silt by treating a sludge suspension contg. aerobes with photosynthetic bacteria. CONSTITUTION:The tilt 2 (sludge) is pumped up from the river 1, and passed through a screen 3 to remove solid matter such as waste cans and glass from the silt 2. The silt agglomerated by fat and oil is introduced into a homogenization tank 4, agitated, and homogenized to obtain a suspension. The suspension is supplied to an aerobic tank 5, converted into a suspension consisting essentially of aerobes, and regulated. The silt suspension is introduced into a photosynthetic bacteria treating tank 6, and aerated 21 therein in the presence of photosynthetic bacteria to decompose the oil and fat dissolved in the suspension at a high speed and to make the suspension harmless. The silt suspension treated with the photosynthetic bacteria is supplied to a separator 7, and separated into a supernatant liq. and the sludge soln. contg. concd. photosynthetic bacteria. The supernatant liq. is introduced into a dilution tank 10, diluted therein, and then discharged without causing secondary environmental pollution.
