Title: Additive for cemental soil solidifier
Inventor: UCHIYAMA YASUHIRO
IPC: C04B11/00
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To obtain an additive which, even when added to a Cr<6+> -containing cemental solidifier reclaimed from industrial wastes, can prevent the solidifier from causing soil pollution by selecting an additive comprising a calcium sulfite powder having a specified solubility when measured by suspending a specified amount of it in a saturated aqueous calcium hydroxide solution and leaving the suspension in a quiescent state. SOLUTION: The calcium sulfite used as an additive for a cemental soil solidifier is a powder having a solubility of 5-100 mg/dm<3> when measured by suspending 0.1 wt.% the sulfite in a saturated aqueous calcium hydroxide solution and leaving the suspension in a quiescent state for 1 hr. The diameter of the powder is 10-40 μm. The calcium bisulfite having a solubility in the above range can supply sulfite ions sustainedly for a long term into soil and can therefore satisfactorily prevent Cr<6+> in the cement from causing soil pollution. The calcium sulfite is not limited on its method for preparation and may be, for example, a by-product from waste smoke desulfurization. It is desirable that this additive is used in an amount of about 50 to 150 times the total amount of Cr<6+> in the cement and soil.

Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To remove organic matter efficiently without raising a feed amount of oxygen by a method wherein a possessed percentage of a microbe stuck to a carrier to all microbes in a biological treatment tank is adjusted. SOLUTION: Water to be treated being raw water is supplied to a perishables treating tank diluting that by introducing treating water into a channel to be treated 1a through a water supply route 8, organic matter in the water to be treated is eliminated with a microbe stuck to a carrier and a floating microbe in the biological treatment tank 1, and the water to be treated containing the floating microbe flows out into a precipitation tank 6 to be separated into sludge and treating water. Such the dilution of the water to be treated adjusts hydrodynamical retention time in the perishables treating tank, and prevents increase of a local load applied in the biological/treatment tank 1.  By adjusting a percentage of the microbe stuck to the carrier in the biological treatment tank 1 by a means of adjusting the hydrodynamical retention time, an oxygen consumption amount is decreased, and even in the case of high load operation, organic matter can be efficiently removed.
