Description

[0001] VOCs REMOVING SYSTEM [0002]

The present invention relates to wastewater treatment, and more particularly, to a treatment system for wastewater and gaseous matter capable of effectively removing vapor and liquid VOCs from wastewater generated in industrial facilities and the like.

As industry develops, population increases, and water pollution load increases, trace harmful substances such as volatile organic compounds (VOCs), which are difficult to solve by conventional water treatment methods, are flowing into the water.

According to the Enforcement Decree of Korea's Atmospheric Environment Conservation Act, VOCs are defined as petrochemical products, organic solvents, or other substances. The scope of the regulation is expanded to 10.3 ㎪ (or 1.5 psia) in the hydrocarbons whose rawe vapor pressure is 27.6 ㎪ or more have.

Representative materials of VOCs include benzene, toluene, propane, butane, and hexane. These VOCs are emitted by human activities, and the painting industry, which includes the use and manufacture of organic solvents, is the largest source of pollution.

VOCs can have a profound effect on long-term exposure to humans and can lead to acute, chronic intoxication, carcinogenesis, genetic mutations and malformations upon ingestion.

At present, waste water containing VOCs is generated in each industrial facility such as petrochemical complex, refinery oil, textile, paint and paper making facility, and dissolved VOCs in wastewater can be removed by treatment such as electrolysis, It is necessary to install a tower, a condensation facility, a separation facility, and a separate hydrotreating facility. In the case of VOCs discharged to an open side, it is impossible to treat the VOCs.

There is a possibility that the VOCs discharged to the open side are condensed in a device such as the closed primary flow control tank and reach the limit value, and the explosion may occur according to the environmental conditions. In fact, the recent explosion of VOCs occurred in H-chemical, which was confirmed by the explosion of VOCs enriched in the openings as described above.

The most common methods for treating degradation wastewater are biological treatment, chemical treatment (O ₃ or Cl ₂ ) or physical treatment (adsorption, filtration, etc.). However, these methods are disadvantageous in that a large amount of solid waste is generated, or a harmful oxidizing agent is used in itself or a lot of sites are required.

Recently, studies on advanced oxidation processes (AOPs) such as electrolysis, ozone oxidation, Fenton oxidation, E-beam and UV / TiO ₂ have been actively researched to solve the problems of existing processes It is progressing. In this high oxidation method, there is a tendency to increase the interest in electrochemical decomposition of organic pollutants in water because of easy automation, high treatment efficiency and excellent environmental suitability.

In this conventional technology, the effluent wastewater in the industrial complex has an advantage of reducing the inflow load of the bioreactor through the electrolysis process, but the above-mentioned risk of accumulation and explosion of VOCs remains.
