Description

Titanium Photoreactor for Wastewater Treatment {PHOTO TITANNIUM CATALYTIC REACTOR TREATMENT TANK}

The present invention belongs to the wastewater treatment apparatus, which is a titanium photoreactor for wastewater treatment using a titanium photoreactor for wastewater treatment, which is currently installed and operated nationwide, especially in the case of high concentration livestock wastewater, from the pretreatment process of various wastewater to below the full legal standard value. The treatment plant is about 15 days from the inflow to the discharge, but if the process using the reactor of the present invention (PROCESS) is adopted, it can be completely processed within 1 hour and 30 minutes, and can handle 5,000㎥ per day in one tank. The present invention relates to a wastewater treatment device in which the treated water is filtered in a very clean manner so that the throughput proceeds proportionally. have.

The wastewater generated as described above is very serious and is intended to be solved nationwide, but the pollution level reaches a very serious condition, and the severity reaches an extremely severe social problem. Particularly, the landfill leachate and industrial wastewater are very serious. to be.

Moreover, in view of the fact that extreme water pollution occurs due to various wastewaters, particularly leachate, livestock waste, manure, and factory wastewater, which are becoming serious social problems, landfill leachate, industrial wastewater, as well as industrial wastewater Although the back is processed by its own filtration device, effluents often fall below the standard value compared to the investment cost, so it is urgent to protect mankind from water pollution by solving environmental problems and preserving water quality. Currently, biological treatment, chemical purification, and natural purification methods are commonly applied to the treatment plant, but there is not enough to treat difficult decomposable materials, and the treatment efficiency is proportional to the high processing cost. In poor condition Therefore, there is an urgent need for a water treatment method for treating difficult degradable materials in a low operating cost and a small space.

Accordingly, the present inventors have devised a photoreactor using a titanium photoreactor for wastewater treatment by devoting to research and development for many years to solve this problem, and developed a titanium photoreactor that can be treated with low cost and high efficiency light effect from domestic wastewater to high concentration wastewater. The present invention has been made of a photoreaction tank for wastewater treatment. The object of the present invention is to use titanium dioxide and ultraviolet rays, and to provide a photocatalyst, and to provide a reaction apparatus tank for photodegrading contaminated water, water and the like by applying the same. In the photolysis reaction, oxygen and hydrogen are generated when ultraviolet rays and light come into contact with titanium dioxide semiconductor and metal as electrodes. At this time, titanium dioxide does not change even in some light and serves as a photocatalyst.

In the titanium dioxide photocatalytic reaction, the reaction takes place on the surface of the catalyst, and the titanium dioxide photocatalyst occurs in the photocatalytic oxidation and reduction reactions, but the photoreaction occurs even when the oxidation power is very strong. In the case of water treatment using a photocatalyst, a method of detecting titanium dioxide powder has been one of the main points, and it is a technical problem in recovering the detected titanium dioxide. (TANK TYPE PHOTO REACTOR) In this case, it has the maximum effect of light sleep, and it makes the photoreaction by making UV transmittance good in the PIPE TYPE PHOTO REACTOR and titanium dioxide in adsorbents such as activated carbon (AC) and silica gel. SPIRAL TYP In addition, various types of reactors have been devised, but they are far less practical and require large scale in terms of reaction efficiency and operating costs. Developed a titanium photoreactor for wastewater treatment. A tank (tank) capable of photolyzing the wastewater was needed to create a titanium photoreaction tank for wastewater treatment where the wastewater was discharged and discharged and the sludge was treated separately.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Installed in the center of the tank (Fig. 2) for storing wastewater in the wastewater treatment titanium photoreaction tank (Fig. 1) of the present invention and mounting a titanium photoreactor (②) for oxidizing various organic substances by generating a photoreaction Water level controller (⑦) to control the inflow of raw water to open and close the inlet (Fig. 6) to control the water level, and the combination of the discharge device (Fig. 7) to discharge the treated water. It is a titanium photoreactor for wastewater treatment that works by interlocking to obtain high quality treated water. The structure and operation of the titanium photoreactor (②) that plays a major role in the photoreaction process will be described. By applying titanium dioxide (Tio2) and irradiating ultraviolet rays inside the quartz tube, it is changed into hydroxyl radical (-OH Radical), which removes the characteristics of the hardly decomposable organic substance and removes the chromaticity. . At this time, the organic substances contacted are oxidized and decomposed into carbon dioxide gas and water.Titanium tube (Ti) is inserted into the bobbin tube in the inside of the titanium tube, and when the current flows through the canal wire, heat and light are generated from the canal wire. As heat and light are conducted to the external titanium tube, the titanium tube generates heat. At this time, when organic substances come into contact with the outside of the titanium tube, various organic substances are oxidized and decomposed into carbon dioxide and water. At this time, the heat generated from the titanium tube increases the water temperature of the waste water, thereby doubling the oxidation of various organic substances. The titanium dioxide is coated on the quartz tube and the ultraviolet rays are radiated from the quartz tube and the boring is performed in the titanium tube. Titanium photoreactor for wastewater treatment (②) consisting of a combination of pipe and canal wires (②) and photoreactor (②) with the same role as above are installed in the center of the tank and the inflow water is adjusted by setting the time to oxidize by the photoreaction. It is a wastewater treatment device that installs a water level controller (⑦) for the purpose and has a discharge port for discharging the treated water to obtain the treated water based on the desired discharged water. The treatment resulted in excellent efficiency and excellent effect under various conditions.

As described above, the photoreactor for wastewater treatment according to the present invention is a tank for photodegrading water to produce high quality treated water, and the size of the capacity is large and small according to the state and amount of wastewater to be treated. Automate to facilitate unattended operation. The advantage is that it can treat a large amount of wastewater in a short time on a small site, and it is possible to get high-quality treated water quickly at low operating costs such as sewage treatment plant, livestock wastewater treatment plant, waste leachate treatment plant, food and drinking water treatment, golf wastewater treatment and heavy water treatment. have.
