摘要： PROBLEM TO BE SOLVED: To miniaturize the device and to surely prevent the occurrence of reddish water by falling an iron component containing waste water to a water storage tank holding a bacteria holding means and provided with an iron oxidizing bacteria through a falling weir and storing the water in a prescribed amount. SOLUTION: The falling weir 13 having a prescribed height is formed at the top end of a flow passage of the iron component-containing waste water 11, and the water storage tank 14 is arranged at its downward side. The waste water 11 falling from the falling weir 13 is stored by a prescribed amount. A horizontal board 18 is fitted at the bottom part side of the water storage tank 14 and the bacteria holding means 19 on which the iron oxidizing bacteria is stuck is mounted thereon. A negative electrode 20 is arranged adjacently to this bacteria holding means 19. A positive electrode 21 is arranged at the upward side of the negative electrode 20 and at the underside of water surface. A spontaneous oxidation is accelerated by falling the waste water 11 from the falling weir 13, and the change of the iron from bivalent to tervalent is accelerated with the iron oxidizing bacteria, and the occurrence of the reddish water is prevented by this constitution.

摘要： PURPOSE:To surely effect dewatering of a large amount of soil having high water content efficiently at reduced treatment cost. CONSTITUTION:A large number of dewatering boards 2 wherein each of the boards comprises a hollow body attached on the front and rear surfaces of a frame filter plates 6, 7 respectively and an elastic packing 9 is attached to the periphery of one or both the surfaces of the hollow body are suspended parallelly and spaced closely from each other from a horizontally provided supporter rail 1 through rollers 4, and the packing 9 is placed between adjacent boards 2, 2 to form an airtight space 11 for loading of soil having high water content, and the boards 2 are connected in series to a telescopic mechanism which expands or contracts the interval therebetween in the direction of the row of the boards. And, a feed hole is provided for each of the boards 2 to force soil S having high water content into the space 11 and a water suction pipe 16 for evacuation by means of a vacuum pump and an air pipe 17 for admitting air are provided in the space of each of the boards 2.

摘要： PURPOSE:To dehydrate the whole of soil to be dehydrated efficiently and uniformly by a method wherein an airtight box body having strainer pipes mounted thereto so as to be turned downwardly is moved and positioned by a transport and press-in machine to be introduced in the soil with high water content of a dehydration tank under pressure and, after dehydration treatment is performed under vibration and vacuum suction, said box body is again positionally changed to repeat the same process. CONSTITUTION:In a dehydration apparatus equipped with a vibrator, an airtight box body 6 having strainer pipes provided thereto so as to protrude downwardly is moved and adjusted up and down or left and right by a transport and press-in machine 8 and allowed to fall at a predetermined position to be introduced in the soil with high water content thrown in a dehydration tank 4 from the upper opening part thereof under pressure. The dehydration tank 4 is vibrated before and after the airtight box body 6 and the strainer pipes are introduced under pressure and the moisture in the soil with high water content is exuded and released to be discharged to the outside by a vacuum pump 11. After this dehydration treatment, the airtight box body 6 and the strainer pipes are again pulled out by the transport and press-in machine 8 to be moved to a separate position to repeat the same dehydration process over the whole of the soil to be dehydrated.
