Problems solved by technology

However, for substances with low solubility in water or hydrophobic substances, the water layer on the surface of the bacteria will hinder their mass transfer rate, resulting in reduced treatment efficiency
In addition, the acidification and drying of the filter bed often deteriorate the treatment effect of the bacteria-based biofilter

Embodiment 1

[0046] The integrated fungal deodorization reactor is a cylindrical container, which is divided into a humidification zone 1, a biochemical reaction zone 2, a humidification solution storage zone 12 and a nutrient solution storage zone 13 by partitions.

[0047] The exhaust gas containing ethanethiol enters the upper part of the humidification liquid storage area 12 through the air compressor, and enters the humidification area 1 through the entrance 5 of the humidification area. The humidifying liquid in the humidifying liquid storage area 12 enters the humidifying area 1 through the humidifying liquid delivery pump 6 . The ascending waste gas is mixed with the descending humidifying liquid, and the humidity of the waste gas is adjusted. The humidity-adjusted waste gas enters the biochemical reaction zone 2 directly from the upper outlet of the humidification zone 1 . In the biochemical reaction zone 2, through cultivation, fungi such as Penicillium permanensis, Paecilomyces...

Abstract

The present invention relates to equipment for treating foul gas via biotechnological process, and is especially one kind of integral fungus deodorizing reactor and its operation method. The integral fungus deodorizing reactor consists of four parts, humidifying area, biochemical reaction area, humidifying liquid storing area and nutritive liquid storing area. The biochemical reaction area is provided with stuffing for fungus microbe to adsorb and grow. In the reactor, foul gas is passed through a central pipe as the humidifying area to be humidified and then made to enter biochemical reaction area directly. The reactor provides fungi and bacteria of different types with habitat for stable growth, and this raises the deodorzing effect effectively. The present invention may be used in treating foul gas from sewage treatment and solid water treatment as well as other type of foul gas.

Description

technical field [0001] The invention belongs to the field of equipment for treating malodorous gas by utilizing biological technology, and in particular relates to an integrated fungal deodorization reactor and an operation method thereof. Background technique [0002] In order to prevent and avoid the impact of the odor of sewage treatment plants on the lives of surrounding residents, some developed countries have successively formulated some specific regulations. For example, Germany stipulates that no living measures shall be built within 300m outside the boundaries of urban sewage plants. If this requirement cannot be met, sewage treatment Necessary measures must be taken in the factory to prevent the spread of odor. my country has built nearly 400 urban sewage treatment plants, most of which are in large and medium-sized cities, and some of them are difficult to avoid residential areas or villages, so their odor problems should also be solved. There are two main types ...
