Explore the world of biological processes for treating VOCs and odors. Learn how microorganisms attached to carrier media break down pollutants into harmless substances, and discover the benefits of biofiltration, biowashing, and biotrickling filtration.

Efficient Treatment of VOCs and Odors: An Overview of Biological Processes

The treatment of volatile organic compounds (VOCs) and odors involves harnessing the power of microorganisms attached to carrier media.

What is biological deodorization equipment？
Biological deodorization equipment uses biological fillers as carriers to enable microorganisms to form biofilms on the surface of biological fillers in a suitable environment. Microorganisms in biofilms use inorganic and organic substances in waste gas as carbon sources and energy sources, and maintain odor by degrading odorous substances. It is an environmental protection equipment that decomposes odorous substances into odor

Source of acid-base waste gas

In some processes that use nitric acid or mixed acid containing nitric acid, such as aluminum pickling, copper pickling, stainless steel pickling, single crystal silicon and polysilicon pickling, diamond pickling, etc., or where nitrates are decomposed, there are often a large number of NOx waste gas (yellow smoke) is discharged. Due to the violent reaction, the instantaneous concentration of NOx is very high.

Acid-base waste gas is

As a commonly used industrial waste gas treatment equipment, the wet scrubber has the advantages of high removal rate and wide application range.

In industrial production, various types of waste gas will be produced, and corrosive waste gas also accounts for a large proportion, and these waste gases need to be purified before they can be discharged. There are many purification treatment equipment, among which the wet scrubber is the more commonly used waste gas treatment equipment.

A wet scrubber is a mechanical system that removes contaminants from a gas stream by contacting it with a scrubbing liquid, most commonly water. Wet scrubbers are often the only air pollution control devices that can remove both particulates and gases/vapors. They are very efficient at capturing the smallest dust particles and can trap them in droplets, eliminating over 99% of airborne p

It is proposed to build a sludge thermal drying plant in the reserved land for a power plant in Chongqing. The project construction is divided into three phases. The scale of the first phase is 600 t/d (moisture content 80%). Considering the fluctuation range of sludge moisture content (75%-82%), the maximum solid flux of treatment is 150 t DS/d.

The composition of waste gas in drug research and development laboratories is relatively complex, mainly including inorganic acid-base waste gas and organic waste gas. Therefore, the waste gas treatment of drug research and development laboratories is divided into inorganic waste gas treatment and organic waste gas treatment. The inorganic waste gas treatment method adopts the spraying acid-base neutralization method. However, because the organic waste gas in the drug research and development

Nowadays, as environmental protection requirements are getting higher and higher, for many industrial enterprises, industrial sludge cannot be discarded and disposed of at will. How to properly dispose of the pollution of industrial sludge has become the premise for the long-term sustainable development of industrial enterprises. The industrial sludge dryer is the core equipment for processing and disposing of high-humidity and high-viscosity industrial sludge. The emergence of this equipment
