Description

Wastewater treatment system {sewage treatment system}

The present invention relates to a wastewater treatment system, and more particularly, to a wastewater treatment system that treats wastewater by classifying ozone treatment, waste ozonation treatment, sludge treatment, and multi-stage filtration treatment.

The amount of wastewater such as sewage and wastewater discharged due to rapid industrialization is rapidly increasing, and along with it, the shape of pollutants is very diverse, facilities for treating them are also sophisticated, and treatment costs are increasing.

In general, wastewater treatment methods are classified into physical purification methods, chemical purification methods, and biological purification methods. Among them, ozone oxidation treatment facility, which is one of the chemical purification methods, can achieve reduction of initial investment cost and operating cost.

Ozone has a strong oxidizing power next to fluorine in nature, so it is used for disinfection, sterilization, and removal of taste and odor at water purification plants, and is widely used for sterilization, disinfection, COD, BOD, and color removal at wastewater treatment plants.

There are two very important elements in the ozone treatment process, one of which is the ozone production technology that increases the concentration of the produced ozone gas, and the other is the ozone dissolution technology that dissolves and reacts the produced ozone gas into water with a high transmission rate.

In the case of the former, the ozone concentration of ozone generators currently used for industrial purposes has been developed and used up to about 12 wt%, so more technology has been developed than the ozone concentration of 2 to 3 wt% in the past.

For high ozone transmission rate, the technology was developed from ceramic diffuser diffusion method to pressurized injection method, and the ozone transmission efficiency was developed up to 95% or more.

However, the conventional pressurized injection dissolution apparatus has a great advantage of high ozone transfer efficiency, and at the same time has a great problem of corrosion of the dissolution apparatus due to the strong oxidizing power of ozone.
