A single-stage or multi-stage biological odor control treatment system for the removal of target vapor compounds from a contaminated air stream consisting of a first stage (onsite non-potable water treatment) where raw collection system non-potable water is extracted from the sewer collection system, screened and sprayed over a media bed where it is treated to secondary effluent water quality and is collected in a tank. The onsite non-potable water treatment system effluent is then pumped to the biological odor control system. This onsite non-potable water treatment system effluent is used for irrigating either a single media bed, or multiple media beds, which require continuous moisture and a source of nutrients. The microorganisms use the odorous compounds in the foul air stream as a food source. Treated air is then discharged to the atmosphere. The odor control treatment system drain water is then returned into the source containment collection point.

A system and method for processing industrial waste gas based on a combination of photoelectrocatalysis and a biotrickling filter, including an industrial waste gas simulation generator, a photoelectrocatalytic reactor and at least one biotrickling filter. The industrial waste gas simulation device transports the industrial waste gas to the photoelectrocatalytic reactor through the buffer tank and the mixing tank by a fan. Then the industrial waste gas is degraded under the synergistic catalysis of the substances with high catalytic activity generated by the plasma reactor and the photocatalyst activated by the ultraviolet lamp.

A washing treatment system includes an odor and flue gas washing tower, a biological deodorization filtering tower, a multifunctional biomass combustion boiler, a liquid fermentation reactor, a solid fermentation reactor, circulating pumps, an exhaust fan and an induced draft fan. An exhaust port is formed in a top end cover of the odor and flue gas washing tower. A liquid inlet, an air inlet and a liquid drainage port are formed in a side wall of a tank body. A hanging basket is placed in the tank body. Organic fillers and/or inorganic fillers are placed in the hanging basket. An inner cavity of the washing tower is divided into a liquid inlet shunting cavity, a filler layer, an air cavity and a liquid accumulation cavity from top to bottom. An upper supernatant in the liquid fermentation reactor is connected with the liquid inlet for washing.
