Exhaust gas treating device

A waste gas treatment system having a burner part and a combustion chamber provided at a downstream side of the burner part. Combustion flames are formed from the burner part toward the combustion chamber, and a waste gas is introduced into the combustion flames, thereby oxidatively decomposing the waste gas. The combustion chamber is formed from an inner wall made of a fiber-reinforced ceramic material. Therefore, the wear of the inner wall due to heat and corrosion is minimized, and thermal stress cracking is also reduced. Consequently, the lifetime of the system increases, and the cost of equipment and the availability factor can be improved. In addition, because the inner wall exhibits no catalytic effect, the formation of thermal NOx is suppressed, and it is possible to achieve environmental preservation and to simplify the treatment equipment.

Method and system for controlling ecological sensitive area blue algae bloom of eutrophic large-size lakes and reservoirs

The invention belongs to the technical field of environmental protection, and particularly relates to a method for controlling ecological sensitive area blue algae bloom of eutrophic large-size lakes and reservoirs. According to the invention, under the action of natural wind power and wind direction, blue algae in a large water area are diverted and converged into an artificially arranged small-range separation area to prevent further escape thereof; then, the blue algae are eaten by algae-eating animals bred at high density in a centralized manner; and when the density of the blue algae is too high, additional manual fishing removal is performed. Effective wave breaking measures are taken to reduce wind waves inside and outside the separation area, thus creating conditions for floating convergence of blue algae. The perennial control on population sources inside and outside an ecological sensitive area reduces the occurrence of blue algae bloom and creates conditions for recovery of other aquatic animals and plants, thus finally forming a benign development situation in which blue algae are less and less and other beneficial organisms are more and more.
