Provided are a system for monitoring a hydroxyl radical scavenging index in water using a real-time multi-fluorescence analyzer and a parallel factor analysis apparatus and a method therefor, wherein the system monitors the hydroxyl radical scavenging index in water using the real-time multi-fluorescence analyzer and the parallel factor analysis apparatus, whereby it is possible to monitor the characteristics of an organic material in target water through a continuous flow analysis method without using an existing indicator material, rhodamine B. In addition, in a water treatment system having an advanced oxidation process (AOP) applied thereto in which ozone, ultraviolet rays, hydrogen peroxide, and the like are combined, it is possible to simply calculate the hydroxyl radical scavenging index in the target water through an organic material characteristic index for each component obtained by classifying the characteristic structure of the organic material in water using real-time fluorescence analysis by means of a parallel factor (PARAFAC) model. Accordingly, the amount of chemical injection and the amount of ultraviolet irradiation, which are process control variables, can be controlled, and under given operating variable conditions, the removal rate of a target material in water is predicted, whereby the system can also be used as a diagnostic tool for process evaluation in the advanced oxidation process. Furthermore, the system can provide operational convenience that enables process control while reducing the amount of power consumed in the advanced oxidation process even though the type of target material and the water quality characteristics of raw water change.

The present disclosure provides a concrete structure strengthened using a grid reinforcement material and non-shrink grout and a method of strengthening the same in which, when strengthening a concrete structure such as a concrete slab or a concrete wall body that is damaged or deteriorated, a grid reinforcement material is mounted on one side of the concrete structure, a formwork is formed on an outer side of the grid reinforcement material to have a required gap, and then the gap is filled with non-shrink grout so that the non-shrink grout is cured therein to strengthen the old concrete structure, thereby being able to automatically fill and repair cracks formed in the concrete structure just by injecting the non-shrink grout without separately performing crack repair on the old concrete structure. Also, the grid reinforcement material may be easily fixed or mounted using a grid fixing device and may be easily applied to strengthening of a concrete structure having a curved surface as well as a concrete structure having a flat surface such as a concrete slab or a concrete wall body. In addition, reinforcing bars may be additionally arranged in a gap between a surface of the concrete structure and the grid reinforcement material so that the grid reinforcement material increases a cover thickness, and thus the concrete structure is remarkably strengthened.

Abstract

Provided are a system for monitoring a hydroxyl radical scavenging index in water by using a real-time multi-fluorescence spectroscopy device and a parallel factor analysis device and a method therefor, wherein the system monitors the hydroxyl radical scavenging index in water by using the real-time multi-fluorescence spectroscopy device and the parallel factor analysis device, whereby it is possible to monitor the properties of organic matter in target water through a continuous flow analysis method without using the existing indicator matter, rhodamine B. In addition, in a water treatment system having an advanced oxidation process (AOP) applied thereto in which ozone, ultraviolet rays, hydrogen peroxide, and the like are combined, it is possible to simply calculate the hydroxyl radical scavenging index in the target water through an organic matter characteristic index for each component obtained by classifying the characteristic structure of organic matter in water using real-time fluorescence spectroscopy by means of a parallel factor (PARAFAC) model. Accordingly, the amount of chemical injection and the amount of ultraviolet irradiation, which are process control variables, can be controlled, and under given operating variable conditions, the removal rate of target matter in water is predicted, whereby the system can also be used as a diagnostic tool for process evaluation in the advanced oxidation process. Furthermore, the system can provide operational convenience that enables process control while reducing the amount of power consumed in the advanced oxidation process even when the type of target matter and the water quality characteristics of raw water change.

Abstract

The present invention relates to a method of removing a high concentration of ammonia from reject water in a sewage treatment process by using methane- and methanol-dependent bacteria and biogas, and more specifically, to ammonia removal in a methane oxidation reactor comprising a methane- and methanol-dependent microbial consortium and biogas, for reducing a nitrogen concentration in reject water that is inevitably generated during the sewage treatment process. By using a synergistic action of the methane- and methanol-dependent microbial consortium and biogas generated in a sewage treatment plant, the present invention reduces nitrogen loads by directly treating a high concentration of ammonium without diluting the reject water from the sewage treatment process, and maintains a desirable water quality of effluents by increasing nitrification efficiency, and thus can improve the water quality of effluent-receiving streams.

A textile grid is precisely disposed at a predetermined position between a mold and a main reinforcing bar using a textile grid fixing device so as to be prevented from being moved by a pouring pressure when concrete is poured, and thus a textile-reinforced concrete structure can be precisely constructed. The textile grid fixing device is fixed to one side of the mold, and the textile-reinforced concrete structure is constructed using the textile grid fixing device such that fine cracks are suppressed from being generated on a surface of concrete. Further, a surface of a concrete structure is protected from an external environment when the textile-reinforced concrete structure is constructed so that a covering thickness of concrete can be reduced, and thus, the textile-reinforced concrete structure can be economically constructed.

Abstract

Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.
