Embodiment Construction

[0024] The technical solutions of the present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Such as Figure 1-2 As shown, the device for treating plant residues in constructed wetlands includes a desulfurization and cooling incinerator 31 and a smoke elimination filter 24 .

[0026] Wherein, the desulfurization and cooling incinerator 31 includes a furnace base 32 whose upper surface is flat with the ground 35, a horizontal straight quadrangular columnar furnace wall 1 fixed on the furnace base 32, and a cover covering the top of the furnace wall 1. board 33, the interior of the furnace wall 1 is divided by the incineration chamber wall 8 and the desulfurization chamber wall 6 to form an incineration chamber 10, a desulfurization chamber 7 and a cooling chamber 2 in sequence, and the incineration chamber 10 is set on one side of the furnace wall 1 There is a feed port 11, and the desulfurizat...

Abstract

The invention relates to the technical field of artificial wetland plant residue treatment, in particular to a method and a device for treating artificial wetland plant residues, which are technicallycharacterized by comprising the following steps: 1) incineration and collection: intensively incinerating the artificial wetland plant residues to release flue gas, and collecting biological black carbon generated after incineration; 2) flue gas desulfurization and cooling treatment: atomizing and spraying a sulfur removal agent on the flue gas to obtain desulfurized flue gas, and cooling the desulfurized flue gas to a normal temperature state; 3) flue gas filtration treatment: uniformly distributing the desulfurized flue gas and then carrying out filtration treatment to form filtered flue gas; and 4) liquefying and discharging of the flue gas: uniformly distributing the filtered flue gas in atomized clear water to form a small amount of oily wastewater, and discharging the oily wastewater, so that the problem that wetland plant residues cannot be reasonably treated is solved, the ecological balance of the constructed wetland is protected under the condition of not polluting the environment, and biomass beneficial to the environment can be generated for recycling.

Description

technical field [0001] The invention relates to the technical field of treatment of plant residues in constructed wetlands, in particular to a method and device for treating plant residues in constructed wetlands. Background technique [0002] In recent years, constructed wetlands, as an ecological engineering technology for sewage treatment developed on the basis of degrading sewage in natural wetlands, have developed rapidly in my country. The artificial wetland treatment system has the characteristics of large buffer capacity, good treatment effect, simple process, and low investment and operation costs. It is very suitable for sewage treatment in small and medium-sized towns, and can effectively improve the water environment quality of regions and river basins. Wetland plants are artificial wetlands. It not only has ecological aesthetic value, but also can directly absorb and enrich nutrients in water, so that the wetland ecosystem can operate stably. [0003] However, ...
