Description

  The present invention is a polluted water purifier that adsorbs and decomposes pollutants in polluted water by suspending a condensation catalyst purifier and oxygen catalyst purifier to separate and decompose pollutants and water.

The conventional polluted water purification structure has mainly been used to remove sludge from the bottom using a dredger to purify rivers, lakes and ponds. Sedimentation at the bottom of the water alone does not lead to an improvement in water quality. Drilling deep into the bottom of the water will also destroy the ecosystem at the bottom of the water and will not improve the water quality. In recent years, with the development of the economy, there are many types of impurities in wastewater due to urbanization and industrial development. In addition, the conventional purification system has many natural purification systems based on the propagation and filtration of microorganisms, and it is difficult for the natural purification system to cope with the current deterioration of water quality. The conventional purification system by propagation of microorganisms and purification by microorganisms and filtration are disclosed in the following published patent information.

  There are also water purification methods by installing large-scale water purification machines, but these purification methods are enormously expensive and have not been successful in the proportion of investment.

  There is also a water quality purification method that allows natural bacteria to be cultivated and propagated, but the culture and propagation due to the regional characteristics and temperature differences of the bacteria is not uniform, and the purification effect differs depending on the regional differences and temperature differences. In winter and at low temperatures, there is a drawback that culture breeding stagnates and the activity stops, and water quality purification cannot be expected because it does not produce results. There is also an underwater purification method that uses both natural bacteria and a filter. However, as mentioned above, it is difficult to expect water purification in a large amount of water by cultivating and breeding bacteria due to differences in local characteristics and temperature. This is the current situation.

Invention disclosure

Problems to be solved by the invention

  As for the water purification equipment other than the conventional final treatment plants described above, large dredging works cost a lot of money, and it is not easy to move due to the introduction of large machinery, and there is a tendency to immovably install it. It is difficult to carry out simple movement activities. Also, in order to increase the purification facilities, investment funds become enormous and purification activities in a wide area are limited.

  The filtration method using large-scale pump circulation is suitable for the instantaneous purification method, but the increase in equipment costs a huge amount of equipment, and there is a limit to the treatment efficiency under the current situation where a large amount of water purification is required. No results can be expected for the investment.

  In addition, there are uncertain expectations regarding the improvement of water quality by cultivating and propagating natural bacteria and the use of filter media due to the uncertain activity due to differences in local characteristics and temperature of natural bacteria.

  The present invention is intended to solve the problem that water purification is delayed and the water quality is worsening due to the conventional configuration as described above, and improves the water quality of polluted water in rivers, lakes, ponds, and regenerates nature. The purpose is to become a foothold for the realization of environmental protection.

Means to solve the problem

  In order to achieve the above-mentioned object, the present invention reviews existing water purification methods, and provides water purification by the action of hydroxyl radicals by installing a condensation purification agent and an oxygen catalyst purification agent in water that can reliably perform water purification. It is a device that can.

  The operation of the first problem solving means is as follows. The water quality can be reliably purified without the need for huge funds. And, considering the result of water purification as the first, rapid water purification is necessary, but it is possible to measure water quality continuously.

  In addition, the action of the second problem solving means is that the agglomerated catalyst purification agent that does not affect the aquatic ecosystem with natural resources and does not affect the aquatic ecosystem comes into contact with polluted water in the water. Purify. The characteristics of the condensation catalyst agent include a hydration reaction and a pozzolanic reaction. The hydration reaction has a physical water absorption action, and its fibrous porous hydrophilic group absorbs and absorbs pollutants, malodorous substances, heavy metals and the like in sludge turbid water.

  As described above, the condensed catalyst purifier installed in water slowly adsorbs the impurities in water. If water purification is expected rapidly, the water quality is rapidly purified by directly dispersing the condensed catalyst in powder form in the polluted water. In that case, a temporary and wide-range water purification is uneconomical because a large amount of condensing purification agent is required. An object of the present invention is to perform continuous water purification with a small investment of funds by retaining the condensed catalyst purifier in water.

  Moreover, the oxygen catalyst installed in the polluted water is a purification device that also uses a catalytic action. Hydroxyl radicals efficiently decompose and absorb impurities in polluted water to purify polluted water.

The invention's effect

  As described above, the polluted water purification apparatus of the present invention can purify polluted water of river, lake water, and pond water quality. Rivers in large urban areas are being improved in water quality due to the spread of upstream sewers, but water quality deterioration is progressing. By utilizing the present invention, purification of water quality can be expected in a wide range.

  The dissemination rate of sewage in local cities is not perfect. Domestic wastewater, untreated factory wastewater, and agricultural wastewater including chemical fertilizers are directly discharged into rivers, lakes and ponds. It causes water quality deterioration and results in progress in the direction of water quality deterioration. It is considered that such contaminated polluted water can be solved by utilizing the polluted water purification apparatus of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1, water is added to a powdery condensation catalyst agent and kneaded to form a mortar. Apply the mortar-shaped condensed catalyst purifier to a square plastic plate. The usage amount of the condensed catalyst purifier is calculated based on the turbidity of the polluted water and the amount of water. About 0.1% of the amount of the condensed catalyst purifier used is about 0.1% of the amount of polluted water. In order to purify large-scale polluted water, the number of mesh plates coated with a condensing catalyst agent can be increased and the apparatus can be used to purify polluted water.

  In FIG. 2, a liquid oxygen catalyst purifier is swallowed into a foamed urethane foam and removed. After drying, this operation is repeated again and inserted into the net after complete drying. The oxygen catalyst purifier inserted in the net is suspended in a polluted water.

  In Fig. 3, the purification device is installed in the polluted water. Condensed catalyst purifiers sink due to the weight of the material itself, but conversely, oxygen catalyst agents are buoyant and lift up, requiring heavy stones for suspension. And it can be suspended in the polluted water and connected to the rope continuously like a long line regardless of whether it is a condensing catalyst purification or oxygen catalyst purification device. If there is water depth, connect several lines vertically. In the case of extensive purification of polluted water, the purpose of purification can be achieved by increasing the number of connecting ropes that suspend the catalyst purification agent.

  The apparatus of the present invention is intended to purify polluted water, but it is conceivable that the purifying effect is delayed in rivers with a rapid flow rate. Equipped with obstructive or warm current lakes, ponds, and rivers, the purification of polluted water can be confirmed in about one month. This purification apparatus is a polluted water purification apparatus that can achieve continuous water purification.

  FIG. 3 is a cross-sectional view of an embodiment of pond purification using an apparatus using a condensation catalyst in the apparatus of the present invention. The amount of water was about 2000 tons, and the purification catalyst agent was connected in three vertical columns, and 50 sets were installed. After suspending the device in the polluted water, about one week has passed, the polluted water and the purification catalyst have merged, and the water in the pond has turned light milky white. The light milky white color disappeared, and the water in the pond gradually began to be purified. After a month, the transparency increased. Further water quality purification can be achieved by continuously suspending the condensed catalyst purification agent.

  The suspended water is continuously purified by suspending the condensation catalyst purification device and the oxygen catalyst purification device of the present invention in a polluted river, lake, or pond.

Claims (2)

  This condensing catalyst made from natural substances that are neutral and neutral has been used mainly for sludge treatment and improvement of highly hydrous soil. The conventional method of construction has been to condense and purify the sludge substance by instantly condensing the sludge substance by spraying the powdered condensing catalyst agent directly on the sludge substance, and condensing and purifying water and impurities. The present invention has been found not to purify the polluted water as a powdered dispersion of the condensing catalyst agent, but to improve and purify the polluted water by suspending and immersing the condensing agent in the polluted water. It is a charge of. What is different from the conventional purification method is that it is not sprayed in the form of powder, but the condensing agent is kneaded with water to a certain hardness, the condensing agent is kneaded into a hard polyethylene grid, and the grid is directly applied to the contaminated water. It is a method of hanging and purifying. In this method, although the above-mentioned powder-like spraying instantly separates and purifies the pollutant, the device in this claim is not instantaneous, but it is gradually suspended by suspending it in the polluted water for a certain period of time. Will be purified. The condensed catalyst agent device is suspended in sludge water, and the polluted water is purified within about one to two months from the start of soaking. However, although the result of water purification may vary depending on the amount of water and the degree of contamination of contaminated water, it is an invention device that can reliably and reliably purify water.   As a conventional utilization method of the oxygen catalyst agent, it has been used as an environmental purification agent in indoor ground space. Even in the indoor space, oxygen exists in the water. It is a device that purifies polluted water using the oxygen catalyst purifier. Oxygen in the contaminated water and the oxygen catalyst purifier come into contact with each other to decompose and remove impurities. As a result of the experiment again, the average value after the oxygen catalyst agent was inserted into the polluted water increased the transparency in about one month, and was able to be purified. The purifying apparatus claimed is a claim for an apparatus for improving and purifying polluted water by suspending and immersing the oxygen catalyst purifier in the polluted water. This device allows oxygen catalyst purifier solution to penetrate into a small cut soft urethane foam, and after drying, repeats the purifier again and repeats the drying so that the catalyst agent can adhere stably to the urethane foam and elute into water. It is a device that can decompose and purify polluted water in a stable state without causing continuous water purification. For installation in polluted water, place the urethane foam with the catalyst agent stably adhered into a nylon net bag in a completely dry state and suspend it in the polluted water. The suspension method for polluted water is to tie a rope for hanging in a longline and individually tie net bags containing urethane foam infiltrated with an oxygen catalyst purifier. This is a pollution purification device in which the polluted water is gradually purified after suspension for about one month and is continuously purified.
