Description

Sequencing complexed ozone hydrogen peroxide and UV lights water treatment apparatus

The present invention relates to a continuous complex ozone water treatment device, and more specifically, to continuously treat wastewater that is not well treated with a conventional device using a minimum energy and a minimum amount of ozone, hydrogen peroxide, and uv irradiation lamps in a short time. A composite ozone water treatment apparatus.

In general, ozone water treatment is a technical field in which the strong oxidation power of ozone and the application method of hydrogen peroxide, uv, etc. are used in combination with ozone, and so on. In the field of water treatment using ozone gas, ozone contact, dissolution and reaction treatment The main method is the injector method, injector method, pressurized pump method, turbine mixer method, oil tube method, ozone gas injection method, etc. Etc.

In the double acid method, ozone gas is diffused into fine bubbles through a diffuser, and water treatment is performed by injecting deep diffuse depth and fine bubble generation by the diffuser. Due to the formation of disconnection and continuous ejection, the problem of line formation and injection energy is low, so that contact, dissolution and reaction are not good, and ozone dissolution efficiency is low due to deterioration of ozone dissolution rate due to prolonged contact time and expansion of self-decomposition. The treatment time is very long (10 to 90 minutes), the exhaust ozone concentration is high, and there are problems such as environmental pollution and practically failing practical use except water treatment.

Other methods, such as injectors, are used in a very limited small-scale field because they do not have a complex processing function that continuously dissolves and reacts rapidly in a single process method. The method of adding hydrogen peroxide first to ozone water treatment by direct indirect reaction without direct reaction of ozone has a problem of excessive consumption of ozone and low treatment efficiency.

The present invention has been made to solve the above-mentioned problems in the prior art, the water treatment to continuously process the process of water treatment by direct reaction of ozone, the injection of hydrogen peroxide, and also water treatment by uv light irradiation as needed. It is an object of the present invention to provide a water treatment apparatus that increases the ozone utilization rate, improves the completeness of the water treatment, and reduces the cost.

The raw water is supplied through the water pump 2 and the ozone generated by the ozone generator 20 is sucked into the treated water using the injector 4 to mix, contact, dissolve, and react.

When ozone is injected into the treated water, the ozone supply distribution controller 19 is used to supply ozone gas generated from a few generators to a plurality of ejectors. The amount of ozone suitable for each ejector is supplied to reduce the cost of ozone generation. In this case, if a reverse flow of the treated water occurs due to a mismatch of the water supply pressure, the ozone generator 20 and the ozone pipe 17 are damaged, so that the reverse flow is prevented by placing the backflow preventer 16.

And, through the ozone decomposer 15 to decompose the residual ozone gas again from the exhaust gas is separated from the water safely.

When the primary treatment is completed, the number of samples is collected through the residual concentration measuring sphere 21 to measure the treatment result of the primary charger.

According to the measurement result, the connection pipe 22 may be used to complete the water treatment only by the first treatment, and the discharge piping 32 may be connected to the mixing piping 26 if the second treatment is required.

In the mixed reactor 27, the treated water injected with hydrogen peroxide is mixed and homogenized to dissolve the residual ozone and promote the reaction to promote the generation of free radicals.

At this time, it is determined whether or not the uv light irradiation 28 according to the water quality of the treated water in the mixed reactor 27, the irradiation amount is determined by looking at the turbidity, color, suspended matter, etc. of the treated water, but the approximate range of use is 0.3 ˜2.0 ws / cm 2.

The treated water is sent to the secondary reactor 29 in which the orifice type reactor 30 is built in, and the secondary reaction is completed while maintaining the reaction pressure and time.

After the secondary treatment, the exhaust gas is safely discharged using the gas-liquid separator 13, the water separator 14, and the ozone decomposer 31 as described above.

As described above, it is possible to reduce ozone generation cost and residual ozone decomposition cost by increasing ozone contact, reaction, and dissolution rate, and by repeatedly reacting residual ozone concentration and ozone gas, reducing ozone usage by 60 ~ 80% than conventional water treatment equipment. In addition, by using hydrogen peroxide injection and uv light irradiation continuously, ozone refractory water quality can be treated without using activated carbon filter in a subsequent process. In addition, it is possible to minimize the size of the ozone water treatment facility and to freely treat the capacity from small to large. Therefore, this treatment device is expected to contribute greatly to the expansion of the ozone treatment application field due to its high economic efficiency, stability and utility, and its high competitiveness, wide application field, and simple treatment facility.
