Embodiment
[0034] See figure 1 , The landfill leachate and waste incineration flue gas combined treatment system shown in the figure is a specific embodiment of the present invention, which specifically includes photobioreactor 101-104, sewage collection tank 200, air pump 30, and pressure regulator 31- 32. Valves 401-421, rotameter 501-510, liquid flow controller 511-512, fluid oscillator 61-64 and ceramic diffuser 71-75. The photobioreactor and the sewage collection tank 200 are the two generation containers for the treatment process. The internal output of the photobioreactor is connected to the inside of the sewage collection tank 200, that is, the fluid inside the photobioreactor flows to the sewage collection tank 200 in one direction. Inside, the inside of the photobioreactor is connected with the percolate mixing and feeding module, and the percolate mixture is input into the photobioreactor through the percolate mixing and feeding module as a culture medium, and microalgae organis...

The invention discloses a landfill leachate and waste incineration flue gas combined treatment method and system. The landfill leachate and municipal sewage are mixed to serve as a culture medium of microalgae organisms, meanwhile, waste incineration flue gas is introduced into the culture medium for aeration stirring of the culture medium, and ammonia nitrogen in the culture medium is consumed and carbon dioxide in the waste incineration flue gas is captured in the microalgae organism cultivation and propagation process; after the microalgae are bred, part of the culture medium containing themicroalgae is output to a sewage collection tank, meanwhile, the waste incineration flue gas is introduced into the sewage collection tank to flocculate and collect the microalgae, and a treated mixed solution is discharged after collection is completed. According to the method, CO2 in the waste incineration flue gas is fixed through photosynthesis of microalgae organisms, chemical substances inthe leachate are utilized and assimilated to achieve the leachate purification effect, and the method has the advantages of being low in investment cost and capable of achieving continuous operation.
Description
Technical field [0001] The invention relates to a combined treatment method and system for garbage leachate and garbage incineration flue gas. Background technique [0002] Garbage incineration / power generation is currently the main technical means for processing domestic garbage, which can process a large amount of garbage in a short period of time and has low processing costs. Waste incineration mainly produces two kinds of pollutants: landfill leachate and waste incineration flue gas. Before the incineration of garbage, a large amount of garbage collection has led to a steady stream of landfill leachate. Landfill leachate is a highly polluted wastewater composed of fatty acids, humic acid and oxalic acid and other toxic organic compounds. High concentrations of BOD, COD (5000–20000mg / L), ammonia nitrogen (3000–5000mg / L NH4+-N or NH3-N), toxic heavy metals and soluble inorganic nutrients. If the landfill leachate is not treated properly, it will cause damage to the ecological ...
