Description

Wastewater treatment system {A sewage and waster water treatment system}

The present invention relates to a wastewater treatment system, in particular, the treated water collected in the storage tank flows into the separator through a filtering tank and a neutralizer input tank to treat particles larger than water, and then the treated water which relaxes impurities in the aging tank is treated with a reaction tank. Purified effluent with self-cleaning ability to separate contaminants during the passage of pressurized flotation and stabilization tanks, and then through filtration and sterilization tanks, through ceramic filter tanks and ozone mixing tanks, ceramic filter tanks and ozone mixing tanks The present invention relates to a wastewater treatment system that allows for discharge.

In modern times, a lot of wastes including various wastes are emitted from homes, factories, and farms. Therefore, water with self-cleaning ability to be purified on its own is severely polluted and cannot be directly used for drinking water. It is a well known fact that it acts as a factor that breaks a lot.

And once polluted water is used a lot of methods and apparatus for the purification to clean, and now, the research for more efficient purification is steadily carried out.

Looking at some of the known methods of purification, the biological method using activated sludge or microorganisms, the chemical method using chemical reactions, and the physical method using electrons or ultrasonic waves are partially used or researched.

However, according to the conventional method of purifying wastewater, not only stable and complete purification is performed, but also high operating costs required for purification, and thus the purification efficiency cannot be increased.

In other words, the conventional biological method using activated sludge or microorganisms is used in many countries internationally to decompose contaminants by microorganisms, but since this is limited in the digestion of microorganisms, it is treated in a state containing high concentrations of waste. In case of waste water having insufficient alkali or acidity, pretreatment is required, and construction cost is high because the installation area must be large as well as being affected by the environment such as time and temperature.

In addition, the chemical treatment method has the advantage of fast reaction speed and simple process, while even if it is difficult to decompose organic matters by biological treatment, the installation and maintenance costs are too expensive to treat wastewater by itself. B was used only as a post-treatment.

In addition, the physical method using electrons or ultrasonic waves is applied to the process of decomposing hardly decomposable substances such as benzene compounds and halogen compounds that are difficult to process by biological methods or chemical methods, but they are not widely used because their effects are insignificant compared to the huge facility and maintenance costs. There was a disadvantage.
