A method and apparatus for cleaning a contaminated gas, the method comprising passing the contaminated gas through at least two cleaning stages of rubber material through which water flows, wherein the gas and the water pass cocurrently though the at least two stages of rubber material.

A system for capturing and monitoring atmospheric polluting agents (1). Includes a protection skeleton (100) that covers and protects the entire system; a power supply module (200), which has the purpose of providing electrical energy to the system; a bioremediation module (300) that captures and bioremediates the polluted gaseous streams that circulate inside it; a control and monitoring module (400), which census and modifies the operation parameters in real time. Finally, at least one particle capture unit (500) that gathers the particles that approach the system. This invention intends to boost the restoration of polluted gaseous streams with a certain concentration of some substance that could represent a risk for the health of the people, namely: CO, CO.sub.2, NOX, SOX, among others, so as the capture of particulate matter 10 (pm 10) and 2 (pm 2). This invention intends to avoid their spread, as well as the damage they cause to the health.

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.
