Problems solved by technology

However, this method consumes a lot of energy. For example, the heating must be heated to 730 or 800°C to effectively decompose. The heat energy consumed must be heated by gas or diesel, and the air and waste water will be heated from room temperature or normal temperature, which will cost a lot of fuel costs.

Embodiment Construction

[0026] see figure 1 , is a schematic diagram of an embodiment of a volatile organic wastewater concentration treatment system. The volatile organic waste water produced by the factory is introduced into an inlet water storage tank 10, which is used as a temporary storage container for the waste water, and then through a waste water inlet water pump 20, the waste water is pressurized from the water inlet storage tank into an evaporator 30, The evaporator 30 is equipped with a heater 31 to heat the waste water. The temperature is set at a slightly higher boiling point of water to evaporate the water and low-boiling substances in it. The remaining high-boiling volatile organic substances in the evaporator 30 are introduced into a concentrated waste The liquid storage tank 40, the concentrated waste liquid storage tank 40 and the waste liquid used to store the evaporator 30 with a higher boiling point than water, after the storage is full, it is controlled by the discharge valve 4...

Abstract

A concentrating system for treating the volatile organic sewage is composed of a raw sewage tank, a sewage pump, an evaporator, a concentrated sewage tank, a condenser, a sewage tank, a pressurizing pump, and a low-boiling-point volatile organic substance treater.

Description

technical field [0001] The invention relates to a waste water treatment system, in particular to 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, the semiconductor industry, and the 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 and deep ultraviolet 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 pr...
