Problems solved by technology

In addition, under the condition of high pollutant load, the growth rate of biomass is too large in the biofilter, resulting in equipment blockage and increased system resistance loss, which greatly shortens the effective service life of the filter material. At the same time, when the pollution load Higher or fluctuating pollutant loads, the performance of the system is less stable

Embodiment Construction

[0029] In order to understand the technical contents of the present invention more clearly, it is further described as follows in conjunction with preferred embodiments of the present invention:

[0030] To purify a 7200m 3 The malodorous gas emitted during the sorting process of garbage with an air volume of / h is used as an example to specifically illustrate the process flow of an enhanced absorption combined gas biological purification method of the present invention.

[0031] Please refer to shown in Fig. 1, from the exhaust gas of the sorting process after the garbage fermentation, the process of using the enhanced absorption combined type gas biological purification method provided by the present invention to carry out the purification process is as follows:

[0032] (1) The exhaust gas first enters the atomization cooling pre-absorption section I: the atomization pre-absorption is realized through the atomization cooling of pipeline 1, the gas temperature is reduced fro...

Abstract

This invention provides a biological purification method of higher concentration of the mixed gas pollution, in particular organic gases and the stench of purification absorption composite type gas. The method first treat the gas used atomization cooling pre-absorption, and used Jet Bubbling washing to washing purify the soluble substances and gas pollution, finally treated the remained major non-water-soluble pollutants, and including a process to purify biological regeneration to purify the liquid absorbing medium of renewable Jet Bubbling washing process. The invention gas purification method is stable, efficient and low cost.

Description

technical field [0001] The invention relates to the field of gas purification technology, and more specifically, relates to an enhanced absorption combined gas biological purification method for purifying high-concentration mixed polluting gases (organic substances and malodorous gases). Background technique [0002] The rapid development of economy and industry in modern society produces a large amount of polluting gases, such as gases containing organic matter and various malodorous gases. These harmful gases are discharged into the environment and bring many adverse effects to the public. [0003] At present, more and more attention has been paid to the purification of such polluting gases. Domestic and foreign purification processes for gases containing organic matter and malodorous gases mainly include physical, chemical and biological processes. It is generally believed that physical and chemical processes have high energy consumption, high investment, and are prone t...
