Example Embodiment

[0030] Embodiment: This embodiment provides a specific way of using the aforementioned treatment device to treat landfill leachate, including the following steps:

[0031] In the first step, use the first delivery pump 4 to transport the landfill leachate in the raw liquid pool 1 to the reaction pool 5, and then put the medicine in the medicine storage tank 8 into the reaction pool 5 through the feeding pump 9, and the medicine and landfill leachate A reaction occurs, causing the macromolecular particles and suspended solids in the landfill leachate to coagulate and precipitate to form sludge.

[0032] In the second step, the second delivery pump 6 is used to transport the landfill leachate and the generated sludge in the reaction tank 5 to the sedimentation tank 7, so that this kind of mixed solution forms stratification in the sedimentation tank 7 under the action of its own weight , the upper layer is the supernatant part, the lower layer is the sediment part, the supernata...

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a treatment equipment for treating leachate with steam. Background technique [0002] Landfill leachate is waste water produced during landfill or temporary stacking. Its water quality has the characteristics of high COD, high salinity, high ammonia nitrogen, and high heavy metals. It is a kind of high-concentration organic wastewater that is difficult to treat; at present, the existing technologies for the treatment of such landfill leachate include MVR mechanical vapor recompression, MBR+NF / RO, DTRO, etc. However, this kind of conventional treatment process usually has problems such as unsatisfactory treatment effect and easy to cause scaling, which needs to be improved. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a treatment device for treating leachate with steam. [0004] In order to solve the above-mentioned techn...
