Embodiment 1
[0029] Embodiment 1: a kind of landfill leachate processing method is characterized in that, comprises the following steps:
[0030] The first step: open the water inlet valve 2, the landfill leachate flows through the adsorption column 1 filled with natural zeolite and boron mud filler, and enters the sequencing batch reactor 11 equipped with a mechanical stirring device 12, and the water inlet flow rate is controlled to 4.8L / min, the delayed water intake time is 0.5h;
[0031] Step 2: After the water inlet is completed, close the water inlet valve 2 of the adsorption column, turn on the air compressor 7, and carry out blast aeration to the landfill leachate in the reactor, the aeration rate is 2.3L / min, and the aeration time is 2.5 hours;
[0032] The third step: turn off the air compressor 7, turn on the mechanical stirring device 12, and perform anoxic stirring on the landfill leachate in the reactor, the stirring rate is 30r / min, and the stirring time is controlled at 1...
Embodiment 2
[0040] Embodiment 2: a kind of landfill leachate processing method adopts the sequence batch reactor 12 that stirring motor 3 and propeller 4 are housed, it is characterized in that, comprises the following steps:
[0041] The first step: open the water inlet valve 2, the landfill leachate flows through the adsorption column 1 filled with boron mud, and enters the sequencing batch reactor 11 equipped with a mechanical stirring device 12, the water inlet flow rate is controlled at 3.4L / min, and the time delay Water intake time is 1.0h;
[0042] Step 2: After the water inlet is completed, close the water inlet valve 2 of the adsorption column, turn on the air compressor 7, and carry out blast aeration to the landfill leachate in the reactor, the aeration rate is 2.4L / min, and the aeration time is 2.0h;
[0043] The third step: turn off the air compressor 7, turn on the mechanical stirring device 12, and perform anoxic stirring on the landfill leachate in the reactor, the stirri...
