Photooxidation based organic waste gas treatment method

Abstract

The invention discloses a photooxidation based organic waste gas treatment method. The photooxidation based organic waste gas treatment method includes: step 1, using a concentration detection systemto detect the concentration data value of waste gas, and sending waste gas with a low concentration data value into a photooxidation device for treatment through an a valve channel by a control module; sending waste gas with a high concentration data value into a low-temperature thermal oxidation device for pretreatment through a b valve, and transferring the pretreated waste gas with a high concentration data value into photooxidation equipment; step 2, conducting cutting, chain scission, burning, and cracking of waste gas molecular chain on the waste gas through a nano-photocatalytic module,employing an ultraviolet mercury lamp for irradiation, and releasing a nano-catalyst for catalytic oxidation of the waste gas; step 3, sending the waste gas into an inert catalytic module, releasingan inert catalyst, and irradiating the waste gas with an ultraviolet mercury lamp to decompose the waste gas into a low molecular compound; and step 4, subjecting the low molecular compound to microbial degradation so as to obtain clean gas.

Description

technical field [0001] The invention relates to an organic waste gas treatment method based on photooxidation, in particular. Background technique [0002] During the production process of Chinese enterprises, workers operate in the workshop, which is in a semi-sealed state. Waste gas generated during the degradation of plant waste is collected by the air duct and then led to the roof for direct discharge. Volatile organic pollutants around the workshop and the outlet have caused environmental pollution. Serious pollution, so it is necessary to treat the organic waste gas before the workshop discharges. At present, there are mainly the following methods for the treatment of waste gas: [0003] 1. Thermal combustion method [0004] Organic waste gas and fuel gas are fully mixed at high temperature to achieve complete combustion. It is suitable for the treatment of combustible gases with high concentration and small gas volume. The purification efficiency is high, and the or...
