Problems solved by technology
Its shortcoming is that it is sensitive to the raw water quality of leachate, and the water yield is easily affected by factors such as SS (suspended solids), electrical conductivity, and temperature; in the two-stage reverse osmosis treatment process, the lack of pre-treatment in the first stage may easily lead to reverse osmosis Membrane clogging, high frequency of replacement, increased treatment costs; low water yield (55%-70% under normal conditions), difficult refilling, increased operating costs

Embodiment 1
[0036] see Figure 1-Figure 5 , in an embodiment of the present invention, a novel mobile leachate treatment method comprises the following steps:
[0037] Step 1: Pump the leachate sewage from the domestic waste landfill into the mobile primary blow-off tank, and the free nitrogen compounds in the leachate can be removed to a certain extent through the aeration and blow-off effect of the primary blow-off tank , and can achieve the effect of balancing water quality;
[0038] Step 2: Put the wastewater passing through the mobile primary stripping tank into the mobile coagulation and sedimentation tank equipment, and remove suspended solids and other pollutants in the wastewater through the dual effects of adding flocculation agents and natural sedimentation;
[0039] Step 3: The wastewater passing through the mobile coagulation and sedimentation tank equipment can be pumped into the horizontal forced circulation evaporation concentration device or the first-level DTRO membrane...

The invention discloses a novel mobile leachate treatment method and equipment, domestic garbage landfill leachate sewage is pumped into a mobile primary air stripping tank, and free nitrogen compounds in the leachate can be removed to a certain extent through the aeration air stripping effect of the primary air stripping tank, and the effect of balancing water quality can be achieved; 2, the wastewater passing through the movable primary air stripping pool enters movable coagulative precipitation pool equipment, pollutants such as suspended solids in the waste water are removed through the dual effects of flocculation agent adding and natural sedimentation, only a very small amount of live steam is needed, the enterprise operation cost is greatly reduced, and environmental pollution is reduced; and the primary DTRO membrane concentrated liquid can be continuously treated, so that the amount of the membrane concentrated liquid is greatly reduced and the recharge amount of the refuse landfill is reduced.
Description
technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a novel mobile leachate treatment method and equipment. Background technique [0002] The general method of leachate treatment in domestic waste landfill: biological treatment + membrane treatment process, the leachate flows into the medium temperature anaerobic pool through the regulating pool, and enters the MBR reactor in the anoxic section after being degraded by macromolecular organic pollutants (MBR and It is called Membrane Bio-Reactor (Membrane Bio-Reactor), which is a new type of water treatment technology combined with membrane separation unit and biological treatment unit), which is mixed with backflow water and enters the MBR in the aerobic section for aeration to remove the leachate TN (the total amount of inorganic and organic nitrogen in various forms in water, including inorganic nitrogen such as NO3-, NO2- and NH4+ and organic nitrogen ...
