| titleOfInvention | Method of reforming and cleaning sludge |
| abstract | PURPOSE: To make bacterium phase conversion of sludge layers and to improve the DO value, pH value and ORP value thereof by injecting a photosynthesis bacterium suspension at 0.5-10l/m 3 to the sludge deposited in the bottom of rivers, lakes, ponds, etc. n CONSTITUTION: Plural photosynthesis bacterium injection points 3 are set to, for example, the sludge layers of a river 2 connected to a discharge path 1 and the photosynthesis bacterium suspension is injected thereto at a ratio of 0.5-10l/m 3 , more preferably 1-3l/m 3 of the volume of the sludge at one time of injection at 10-20 day intervals. The conversion of the bacterium phase in the sludge layers at the sample points 4 is observed as the temp. of the water rises in 2-2.5 months after the injection of the photosynthesis bacteria (in around March). The dissolved oxygen concn. DO begins to increase and the decrease of the pH value is suppressed; in addition, the oxidation reduction potential ORP increases and the sludge layers are gradually reformed. The oil components in the sludge are decomposed away and the tackiness of the sludge is lost; moreover, the thickness of the sludge layers is reduced and further, the generation of malodors is obviated. n COPYRIGHT: (C)1990,JPO&Japio |
