Odorous and odorous exhaust gas

Biological filtration towerIt refers to organic matter carriers used for treating or degrading pollutants such as odors, volatile compounds that are easily biodegradable, and compounds that do not produce acidic by-products. Such as soil, peat, compost, sawdust, shrubs, etc.Biological filtration towerIt has the advantages of few equipment, simple operation, no need for additional nutrients, low investment and operating costs, and high removal efficiency, and is widely used in agricultural production, such as oxidizing methane to carbon dioxide.Biological filtration towerThe main disadvantages of the reactor are: large reactor volume, lack of circulating water phase, difficult control of reactor operating conditions, long-term operation of the packing will be decomposed and compacted, resulting in increased pressure drop inside the reactor and affecting mass transfer efficiency; In the process of handling sulfur-containing and chlorine containing odorous gases, the fillers may also acidify and need to be replaced regularly.

BedBiological filtration towerBiological filtration can be carried out in enclosed units. The pool water is pumped into a filter chamber equipped with specially designed silica sand, which moves in a vortex in a constantly moving suspension. Bacteria growing on the surface of these particles can remove biological substances from the water, and then, like ozone and protein separation equipment, the treated water returns to the pond under gravity.

Biological filtration towerAlso known as submerged biological filtration system, its main function is to separate ammonia nitrogen and nitrite in water. After a certain period of use, it can form an effective biological chain, which is a very important equipment for aquaculture.

The process of purifying fluids through special devices involves various filtration methods and uses a wide range of materials, including solid-liquid, solid gas, large particles, and small particles. Filtering is the operation of separating solids and other substances from liquids (or gases) by allowing the liquid (or gas) in a suspension (or gas containing solid particles that generate heat) to pass through a medium under the action of driving force or other external forces. Solid particles and other substances are intercepted by the filtering medium.
