A deodorization treatment apparatus according to an embodiment of the invention includes a deodorant tank housing microorganism-retaining carriers, supplied with odorous gas, and discharging an exhaust gas in which an odor has been removed by the microorganisms, a water sprinkler device, a water tank, a water sprinkler pipe, an exhaust pipe, a first blower, an aeration device, and a control device controlling at least one of blowing amount of the first blower, watering amount or watering frequency of the water sprinkler device, amount of air bubbles generated in liquid of the aeration device, water supply to the water tank, drainage from the water tank, or temperature of the deodorant tank according to measurement results.

Managed ecosystems, methods for producing managed ecosystems and methods for using managed ecosystems for sequestering carbon dioxide are described herein. Produced water is obtained and purified to sustain a managed ecosystem with saline-tolerant vegetation. The managed ecosystem biologically sequesters carbon dioxide by photosynthetically absorbing carbon dioxide from the atmosphere and by decomposition into a layer of sediment on the ecosystem floor.

The invention discloses a preparation method and application of in-situ high-efficiency degradation carbon based material of VOCs in landfill based on waste regeneration, which comprises the following steps: air drying the agricultural and forestry wastes to a moisture content of 0.001 wt %˜20 wt %, and the agricultural and forestry wastes mainly include: straw, wheat straw, leaves, branches, weeds, crushing them to a particle size of 0-50 mm with a grinder, and then using urea or amide as modifier The nitrogen enriched biochar was prepared by mixing the crushed agricultural and forestry wastes with a mass ratio of 1:50-1:10; the nitrogen enriched biochar was prepared by retorting the nitrogen doped agricultural and forestry wastes at 300-600° C. for 20-60 min, and then cooling them rapidly; the nitrogen enriched biochar was mixed with the sewage sludge with a moisture content of 90-98 wt. % with a weight ratio of 20:1-10:1 to get the nitrogen enriched microorganism The degradation efficiency of TVOCs in landfill is 96.74%˜99.70%.

A radial flow processing device includes a body with an inner chamber, a pair of inner and outer concentric tubes extending into the body, and a processing disk containing a central opening through which the inner tube extends, the disk being connected with the inner tube. The body has a top wall, a bottom wall, and at least one side wall which define the inner chamber. The bottom wall, top wall, or both, contain at least one opening through which at least one tube extends. A diameter of the inner tube is less than a diameter of the outer tube such that there is a space between both tubes, and a diameter of the disk is less than a width of the body.

A system for removing undesirable compounds from contaminated air includes a biofilter having an alkaline material introduction system and a fuzzy-logic based controller. A contaminant, such as hydrogen sulfide, is removed from contaminated air by passing the contaminated air through the biofilter.
