Abstract

The invention provides a VOCs treatment process for cold regions. The VOCs treatment process comprises the following steps: biological treatment stage: introducing waste gas into a biological treatment unit, heating, washing, dissolving the washed waste gas into water, capturing and absorbing organic pollutants by virtue of microorganisms, and decomposing and converting the organic pollutants intoharmless compounds by virtue of the metabolism process of the microorganisms; deep treatment stage: sequentially carrying out deep treatments including adsorption filtration, desorption resolving andcooling processing on the waste gas in a deep treatment unit after the biological treatment stage so as to remove VOCs organic gas which cannot be removed in the biological treatment stage and has poor water solubility; and discharging stage: discharging standardized gas treated through the deep treatment unit by virtue of a discharging chimney. According to the VOCs treatment process provided bythe invention, the problem that VOCs in the cold regions cannot be effectively treated by virtue of an existing VOCs treatment process is effectively solved.

Description

technical field [0001] The invention relates to the technical field of waste gas, in particular to a VOCs treatment process in cold regions. Background technique [0002] In my country, VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 133.32Pa at normal temperature and a boiling point below 50-260°C at normal pressure, or any organic solid that can volatilize at normal temperature and pressure. or liquid. Its harm is that it can cause chronic poisoning, damage to the liver and nervous system and other chronic diseases. Research has found that VOCs will produce PM2. Small size, large area, strong activity, easy to attach toxic and harmful substances, can cause lung cancer and other related diseases. Ozone at low altitudes can cause respiratory inflammation, damage bronchi and other diseases. With the strengthening of people's awareness of the hazards of VOCs and the introduction of a series of environmental protection...
