The present invention provides a system for microalgae carbon fixation regulated based on natural environmental changes, which includes the following units: a microalgae cultivation unit; a light condensing unit configured to receive sunlight and increase light power density, the light condensing unit including one or more angle-adjustable light-condensing reflective panels; a light splitting unit configured to receive and split light transmitted from the light condensing unit, the light splitting unit including one or more angle-adjustable light splitting panels, the light splitting panel being capable of transmitting light within a spectral band in which microalgae has highest photosynthetic efficiency to thus allow the light to irradiate the microalgae cultivation unit, while being capable of reflecting light within other spectral bands; and a thermosiphon temperature control unit configured to control a temperature of the microalgae cultivation unit by controlling an opening degree of an air regulating valve above the microalgae cultivation unit.

A method for carbon capture and storage includes growing in water a biomass of photosynthetic microorganisms that capture carbon from a carbon source for growth; removing a portion of the biomass; and storing the removed biomass portion in an underground formation for carbon sequestration.

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 system for removing undesirable compounds from contaminated air includes a biofilter having sintered glass media. Hydrogen sulfide is removed from contaminated air by passing the contaminated air through the biofilter.

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) that includes a protection skeleton (100) that covers and protects the entire system; a power supply module (200) for 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 and at least one particle capture unit (500) that gathers the particles that approach the system. The system boosts the restoration of polluted gaseous streams with a certain concentration of some substance that could represent a risk for the health of the people.

The present invention discloses a strain of Lysinibacillus fusiformis with methylamine degradability and the application thereof. This strain, named Lysinibacillus fusiformis GDUTAN2, was deposited on May 24, 2017 in the China Center for Type Culture Collection in Wuhan University, Wuhan City, Hubei Province with a deposit number of CCTCC NO. M 2017284. This Lysinibacillus fusiformis GDUTAN2 was Grain-positive and rod-shaped, and the colony appeared to be round, white and transparent, having a diameter of 1-2 mm. The Lysinibacillus fusiformis GDUTAN2 of the present invention can be applied to environmental restoration, degrading methylamine in the environment at a high degradation efficiency. When it degraded methylamine for 96 h at a substrate concentration of 130 mg/L, the degradation efficiency could reach 32.8%.
