Abstract:
The present invention relates to a composite microorganism reactor, wherein both dephosphorization and denitrification occur in one reactor, and an apparatus and a method for water treatment using the same. The composite microorganism reactor according to the present invention comprises: an inner space for accommodating sewage and waste; a partition wall placed in the inner space to divide the same into an anaerobic region for dephosphorization and an anoxic region for denitrification; a sewage and waste inlet portion placed at the upper portion of the anaerobic region; a sewage and waste outlet portion placed at the upper portion of the anoxic region to discharge sewage and waste outside; a sludge discharge hole placed at the lower portion of the inner space to discharge sludge precipitated in the sewage and waste flowing into the inner space; and a sewage and waste agitation device provided at the anaerobic region to agitate the sewage and waste of the anaerobic region, wherein the sewage and waste flowing into the anaerobic region through the sewage and waste inlet portion pass through the lower end of the partition wall to flow into the anoxic region, and then rise at the anoxic region to be discharged outside through the sewage and waste outlet portion.
Abstract:
The present invention relates to a continuous separation and discharge apparatus and method of solid catalysts and liquid products for Fischer-Tropsch synthesis reactions, and more particularly, to a continuous separation and discharge apparatus and method of solid catalysts and products for Fischer-Tropsch synthesis reactions involving the conversion of synthetic gas into synthetic oil, by which products of the Fischer-Tropsch synthesis including wax, as a long-chain hydrocarbon, can be stably obtained by continuously separating the products from a slurry comprising solid catalyst particles and the products using periodic pulses of a feeding gas and discharging the products through a lower portion of a reactor. Provided is a continuous separation and discharge apparatus of solid catalysts and products for Fischer-Tropsch synthesis reactions including: a level sensing device which is installed at an upper portion of a reactor and detects the slurry-level of reactants; a solid catalyst/product separation device and a discharge device which are installed at a lower portion of the reactor and separate and discharge liquid products from a mixed slurry in the reactor; and a control unit which receives a signal from the level sensing device to open and close the discharge device, wherein the separation device filters the solid catalysts, and the discharge device continuously discharges the products separated from the solid catalysts through the lower portion of the reactor by the amount of the synthesized products measured by a level sensing device.

Abstract:
The present invention relates to a floating filter module installed in a water treatment apparatus, such as in a public water treatment plant, a village water supply facility, a public sewage treatment plant, a wastewater treatment plant, or a village sewage treatment plant, in order to remove contamination particles. The floating filter module according to the present invention comprises: a hollow-type sintered filter having a plurality of fine pores which is arranged in wastewater within a water treatment tank in order to separate and filter the contamination particles from the wastewater introduced into the water treatment tank; a floating body connected to the sintered filter, and which floats to the surface of the wastewater within the water treatment tank so as to position the sintered filter at the upper portion of the wastewater in the water treatment tank; a main pipe communicating with an inner space of the sintered filter; a suction device coupled to the main pipe in order to provide a suction force to the sintered filter through the main pipe, thereby suctioning the wastewater in the water treatment tank through the plurality of fine pores and into the sintered filter; and a compressed-air supply apparatus having a compressed-air supply tube communicating with the inner space of the sintered filter through the main tube and an air compressor coupled to the compressed-air supply tube in order to supply compressed air into the inner space of the sintered filter, thereby releasing from the sintered filter the contamination particles that clog the fine pores of the sintered filter.
