Description

Titanium photoreactor for wastewater treatment {PHOTO TITANIUM CATALYTIC REACTOR TREATMENT TANK}

The present invention is developed as a nationwide environmental movement due to the severe water pollution caused by various wastewaters, especially leachate, livestock waste, manure, and factory wastewater, which are seriously social problems, and the present inventor is devoted to research and development for many years. Developed a photoreactor using titanium photoreactor for wastewater treatment and developed a treatment device that can treat wastewater to high concentration wastewater with low cost and high efficiency to solve environmental problems and protect humankind from water pollution by conserving water quality Invented.

The present invention belongs to a wastewater treatment apparatus, which is a titanium photoreactor for wastewater treatment using a titanium photoreactor for wastewater treatment. The treatment period from inflow to discharge is about 15 days or when the treatment process using the reactor of the present invention is adopted, it can be completely processed within 1 hour and 30 minutes, and can handle 5,000 m³ per day in a tank. The present invention relates to a wastewater treatment apparatus in which the treated water quality is filtered very cleanly. Generally generated wastewater can be classified into domestic sewage, livestock wastewater, manure, industrial wastewater, and waste leachate.

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

Therefore, landfill leachate, industrial wastewater, as well as livestock wastewater are treated by using a filtration device, but effluents often fall below the standard value compared to investment costs. The treatment plant currently implemented in each treatment plant generally applies biological methods, chemical methods, and natural purification methods, but it is not enough to treat hardly decomposable materials, and the treatment efficiency is low in proportion to the high processing cost. Therefore, there is an urgent need for a water treatment method for treating hardly decomposable materials in a low operating cost and a small space. Therefore, in order to solve the problem of wastewater treatment using photocatalyst, technicians and scientists tried to approach the practical use, but it was insufficient in practical level, but I developed the titanium photoreactor by developing it and invented the photoreactor for wastewater treatment that uses it. Was done.

Therefore, the present invention uses titanium dioxide and ultraviolet rays, and relates to a photocatalyst, which is a reaction apparatus tank for photolyzing water and the like by applying the same. On the other hand, in the photolysis reaction, when titanium dioxide semiconductor and metal are used as electrodes, oxygen and hydrogen are generated when ultraviolet rays and light reach. At this time, even in some light, titanium dioxide does not change and serves as a photocatalyst.

In titanium dioxide (Tio2) photocatalytic reaction, the reaction takes place on the surface of the catalyst. Titanium dioxide photocatalyst has oxidation and reduction reactions on the surface of the photocatalyst, but the oxidation power is very strong and the oxidation power of chlorine or ozone used in water treatment is reduced. The light reaction occurs even when irradiated with ultraviolet light. It is used for water treatment, which contributes to the purification of water quality, and the method of detecting titanium dioxide powder when water treatment using photocatalyst has been one of the main points, and has become a technical problem in recovering the detected titanium dioxide. In order to solve this problem, TANK TYPE PHOTO REACTOR, in this case, has the maximum effect of light sleep, and it causes the light reaction to improve the transmittance of UV rays in the PIPE TYPE PHOTO REACTOR and activates the carbon. A device that detects titanium dioxide in an adsorbent such as silica gel and causes a catalytic reaction after fixation. In addition, a spiral type photoreactor (SPIRAL TYPE PHOTO REACTOR) has various types of reactors, but it is not practical for practical use. In many respects, such as reaction efficiency and running costs, they need to be large. In response, the company developed a titanium photoreactor for wastewater treatment capable of treating a large amount of high concentration suspended wastewater. A tank (tank) capable of photolyzing wastewater was needed, and the inventors invented a titanium photoreactor for wastewater treatment that separates and discharges wastewater and treats sewage separately.
