Problems solved by technology

However, this method is very energy-intensive. For example, heating must be heated to 730 or 800 degrees Celsius to effectively decompose. The heat energy consumed must be heated by gas or diesel to heat the air and wastewater from room temperature or normal temperature, which consumes a lot of fuel. cost

Embodiment Construction

[0026] Such as figure 1 The schematic diagram of the embodiment of the volatile organic wastewater concentration treatment system is shown. The volatile organic wastewater produced by the factory is introduced into a water inlet storage tank 10, which is used as a temporary storage container for the wastewater to enter, and then passed through a wastewater inlet pump 20. The wastewater From the water inlet storage tank, it is pressurized into an evaporator 30, and the evaporator 30 is equipped with a heater 31 to heat the waste water. The remaining high-boiling-point volatile organic substances are introduced into a concentrated waste liquid storage tank 40, and the concentrated waste liquid storage tank 40 is used to store the waste liquid with a higher boiling point than water in the evaporator 30. Controlled, and then transported to a professional waste liquid treatment plant in barrels or trucks. As far as the semiconductor industry is concerned, the concentration ratio o...

Abstract

The invention relates to a concentration treatment system for volatile organic wastewater, which comprises a water intake channel, a waste water inflow pump, an evaporator, a concentrated waste liquor storing tank, a condensing apparatus, a exhausted liquid storing tank, a pressure pump, a low boiling point volatile organics processing unit, wherein the evaporator heats and evaporates the lower boiling organic chemicals in the waste water, and collects the residual lower layer concentrated higher boiling organic compounds in the evaporator, the condensing apparatus condensates the evaporated low boiling point organic chemicals and water, the pressure pump conveyors them into low boiling point volatile organic processing unit, which decomposes the low boiling point organic compounds or separates with water, the treated water is discharged.

Description

technical field [0001] The invention is a waste water treatment system, specifically a volatile organic waste water concentration treatment system. Background technique [0002] Industrial wastewater containing volatile organic compounds is an environmental problem encountered by many advanced industries recently, such as the electronics industry, semiconductor industry, and liquid crystal display manufacturing industry. For example, the electronics industry is a key industry for Taiwan's economic development. Advanced electronics industries, such as the semiconductor industry, use ultraviolet light and deep ultraviolet light step exposure technology. As important steps in the manufacturing process, photoresist, development, etching, Chemical agents such as photoresist removal, and the main components of the accompanying industrial wastewater also contain such photoresist, photoresist agent, developer, etching chemicals and other components. Based on environmental protection...
