On the basis of the above structure, when the device in this embodiment is applied, the leachate generated in the domestic waste is firstly discharged into the leachate pool 50, the leachate in the tank 10 can flow into the tank 10 through the water inlet pipe 20 by communicating the leachate pool 50 with one end of the water inlet pipe 20 and then communicating the other end of the water inlet pipe 20 with the tank 10, and because the water outlet pipe 30 is further arranged on the tank 10, one end of the water outlet pipe 30 is communicated with the tank 10, the leachate can enter the deacidification tank 60 through the water outlet pipe 30 after entering the tank 10 for deacidification treatment and then be discharged for other purposes, and further, because the tank 10 is also connected with the driving pump, the leachate in the tank 10 can flow in the tank 10 and the deacidification tank 60 circularly after the driving pump is started, so that the leachate can be recycled.

Specifically, when the leachate is treated, a biological method, a physical and chemical method and a membrane treatment method are often adopted to enable the leachate to reach the national emission standard, and then the leachate is discharged into the ground, so that the treatment efficiency of the traditional method is low, the effluent cannot reach the standard, and the input cost is high.

Therefore, in the application of the device for recycling leachate and pickling water in this embodiment, the leachate pond 50 for treating garbage is communicated with the water inlet pipe 20 on the box body 10, so that the leachate can be discharged into the box body 10 through the water inlet pipe 20, and since the water outlet pipe 30 is further arranged on the box body 10 and is communicated with the deacidification tank 60, the leachate in the box body 10 can be led out to the deacidification tank 60 through the water outlet pipe 30 for deacidification and recycling, so that the leachate is not required to be discharged into the ground through biochemical treatment, the environment is protected, and a certain input cost is saved.

Further, after the percolate after filtration and precipitation enters the deacidification tank 60, plankton (activated sludge) in the liquid can be fixed through the filler in the deacidification tank 60, so that the problems of expansion and loss of the activated sludge are avoided.

Preferably, when the device in this embodiment is applied to a household garbage incineration treatment apparatus, the garbage leachate discharged from the household garbage may be precipitated by the water tank in this embodiment, then discharged to the deacidification tank 60 for secondary purification, and then sprayed back to the incinerator, or the purified water is directly pumped by the driving pump to clean the incinerator, the spray tower, etc. or cool the apparatus, which may be applied to other environmental protection fields.

It should be noted that the water tank in this embodiment may be made of stainless steel or concrete, and the driving pump may be an existing water pump.

Further, a partition plate 13 is provided inside the tank 10, the tank 10 is partitioned into a first tank 11 and a second tank 12 by the partition plate 13, and the water inlet pipe 20 is communicated with the first tank 11 so that the percolate is introduced into the first tank 11 through the water inlet pipe 20.

Specifically, since the partition 13 is disposed inside the tank 10, the tank 10 is divided into the first tank 11 and the second tank 12 by the partition 13, and the water inlet pipe 20 is communicated with the first tank 11, so that the percolate can be led into the first tank 11 to be precipitated through the water inlet pipe 20.

It should be noted that, the water inlet pipe 20 may be made of a conventional stainless steel pipe or other corrosion-resistant materials, and the water inlet pipe 20 may be connected to the first tank 11 by welding.

Further, a through hole 131 is provided in the top of the partition 13, and when the percolate overflows from the first tank 11, the percolate is introduced into the second tank 12 through the through hole 131.

Specifically, since the percolate precipitates after entering the first tank 11, the water phase at the top of the percolate in the first tank 11 is relatively clean, and at this time, when the percolate overflows the first tank 11 due to the first precipitation of the first tank 11 by providing the through hole 131 at the top of the partition 13, the relatively clean percolate at the top of the first tank 11 can be led out into the second tank 12 through the through hole 131 at the top.
