VOCs waste gas green treatment process capable of reducing carbon emission

Abstract

The invention discloses a VOCs waste gas green treatment process capable of reducing carbon emission, which comprises the following steps: carrying out active dynamic membrane absorption treatment, circulating aqueous solution demolding treatment, biological carbon sequestration treatment, sludge treatment and the like on industrial VOCs waste gas to realize biological carbon sequestration in most of VOCs and reduce carbon dioxide emission, and has the advantages of low hazardous waste generation amount, high treatment efficiency, low energy consumption, environmental protection and the like. The hazardous waste treatment cost is low; the VOCs treatment system is low in energy consumption, low in operation cost, stable in operation effect and capable of stably achieving ultralow-concentration emission for a long time.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and in particular relates to a VOCs green treatment process for reducing carbon emission. Background technique [0002] Volatile organic compounds (referred to as VOCs) are various organic compounds with a boiling point of 50 to 260 °C under normal pressure. Therefore, VOCs contain a wide range of compounds, including alcohols, aldehydes, ketones, fatty acids, benzene and its derivatives, phenols and its derivatives, etc. In the development of petrochemical, pharmaceutical synthesis, plastic materials, building materials and other industries, social life has been greatly improved, and the economic level has been greatly improved. Therefore, the treatment of VOCs waste gas has become a hot issue concerned by researchers in scientific research institutes and enterprises. [0003] At present, the common methods for treating VOCs waste gas are catalytic combustion method, photocatalytic method, b...

AI Technical Summary

Problems solved by technology

The disadvantages are: the photocatalyst needs to be attached to the carrier and irradiated by ultraviolet light. In order to avoid insufficient light, the internal structure of the equipment and the placement of the carrier are strictly required; when the concentration of the organic component is low, the photocatalytic oxidation speed slows down, resulting in Harmful intermediate products, poisoning the catalyst, and causing secondary pollution

However, there is a common problem in the above-mentioned treatment methods, that is, the conversion of VOCs into carbon dioxide and water does not reduce carbon dioxide emissions.
