DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 As shown, the utility model provides the following technical solutions: a landfill leachate pretreatment device comprises: a filter box 1, a feed pipe 2 is connected to the top of the filter box 1, a first material guide pipe 3 is connected to the bottom end of the filter box 1, a filter screen pool 4 is arranged in the filter box 1, a sedimentation box 5 is installed at the discharge end of the first material guide pipe 3, a second material guide pipe 6 is connected to the liquid outlet end of the sedimentation box 5, a storage box 7 is arranged on one side of the sedimentation box 5, a cover body 8 is installed at the top end of the storage box 7, a first discharge pipe 9 is connected to the bottom end of the storage box 7, a feeding box 10 is installed at the discharge end of the first discharge pipe 9, a motor 11 is installed on the side wall of the feeding box 10, a rotating shaft 12 is connected to the output end of the motor 11, a rotating blade 13 is installed on the outer wall of the rotating shaft 12, a second discharge pipe 14 is connected to the discharge end of the feeding box 10, and the second discharge pipe 14 is communicated with the sedimentation box 5.

[0023] Through the above technical solution:

[0024] When in use, the landfill leachate is introduced into the filter box 1 through the feed pipe 2, and the filter pool 4 performs preliminary filtration on the leachate to separate the solid particles and large particles of pollutants in the leachate for subsequent treatment. Then the leachate enters the sedimentation box 5 through the first feed pipe 3 for sedimentation. The storage box 7 stores a reagent that promotes sedimentation. When it is necessary to add reagents to the sedimentation box 5, the valve on the first feed pipe 9 is opened, and the motor 11 is started. The motor 11 drives the rotating blades 13 to rotate through the rotating shaft 12. The rotating rotating blades 13 allow the reagents to enter the sedimentation box 5 through the second feed pipe 14. The feed speed can be regulated by controlling the rotation rate of the rotating shaft 12. By controlling the reagent replenishment rate, the dosage of the reagent can be adjusted according to actual needs to avoid waste caused by excessive use of the reagent, thereby saving costs and avoiding excessive addition. Excessive addition of reagents may cause unnecessary waste of reagents and may even have a negative impact on the treatment system, such as changes in sludge properties or adverse reactions. Controlling the replenishment rate can avoid this situation.

[0025] See also Figure 1 , Figure 3 and Figure 6 As shown, a storage groove 15 is opened at the lower part of the inner wall of the sedimentation box 5, and a pushing plate 17 is arranged in the storage groove 15. An electric telescopic rod 16 is installed on the side wall of the sedimentation box 5, and the output end of the electric telescopic rod 16 is connected to the pushing plate 17. A through groove 18 is opened on the side wall of the sedimentation box 5, and a protective door 19 is installed outside the through groove 18. A material receiving pool 20 is provided below the protective door 19.

[0026] Through the above technical solution:

[0027] When it is necessary to clean the sediment in the sedimentation box 5, start the electric telescopic rod 16, open the protective door 19, and the electric telescopic rod 16 drives the pushing plate 17 to push the sediment out of the through groove 18. The receiving pool 20 collects and processes the sediment. Cleaning the sediment in time can effectively avoid excessive accumulation of sludge, prevent sludge from deteriorating and generating odor, and reduce the difficulty of processing. Cleaning the sediment in time can effectively prevent blockage and damage of the equipment, extend the service life of the equipment, and reduce maintenance and repair costs.

[0028] For further information, see Figure 1 and Figure 4 As shown, a processing box 21 is installed at the liquid outlet end of the second material guiding pipe 6 , a third material guiding pipe 22 is connected to the bottom end of the processing box 21 , and a plurality of culture plates 23 are arranged in the processing box 21 .

[0029] Specifically, the liquid in the sedimentation tank 5 is introduced into the treatment tank 21 through the second material guide pipe 6, and the multiple culture plates 23 are respectively cultured: aerobic bacteria, which need oxygen for metabolic activities. They can usually oxidize organic matter into carbon dioxide and water and generate energy. In leachate treatment, aerobic bacteria can degrade organic waste into inorganic matter through biological oxidation-reduction; nitrifying bacteria, which can convert ammonia nitrogen into nitrate. Nitrifying bacteria play an important role in leachate treatment. They can convert ammonia nitrogen in ammonia-containing wastewater into relatively stable nitrate, reducing pollution to the environment; denitrifying bacteria, which can use nitrate and nitrite as electron acceptors for respiratory metabolism to produce nitrogen gas or nitrogen oxides. Denitrifying bacteria are active under anaerobic conditions. In leachate treatment, nitrate and nitrite can be reduced to nitrogen gas, thereby achieving nitrogen removal.

[0030] For further information, see Figure 1 and Figure 5 As shown, a liquid pump 24 is installed on the third material guide pipe 22, and the liquid outlet end of the liquid pump 24 is connected to the fourth material guide pipe 25, and a purification box 26 is installed at the liquid outlet end of the fourth material guide pipe 25, and a discharge pipe 27 is connected below the purification box 26. The purification board 28 is an activated carbon board, which has a large number of micropores and surface area, and can effectively absorb organic substances in the leachate, such as organic dissolved substances, dyes, grease, etc. These organic substances will be adsorbed and fixed on the surface of the activated carbon, thereby purifying the leachate.

[0031] Furthermore, a purification plate 28 is provided in the purification box 26 , and a snap-on assembly is provided between the purification plate 28 and the purification box 26 .

[0032] Furthermore, the card connection assembly includes a card slot 29 and a card block 30 . The card slot 29 is provided on the inner wall of the purification box 26 , and the card block 30 is installed on the outer wall of the purification plate 28 . The card slot 29 and the card block 30 are adapted to each other.

[0033] Specifically, the liquid pump 24 is started to deliver the liquid in the treatment box 21 to the purification box 26 through the third material guide pipe 22 and the fourth material guide pipe 25. The purification plate 28 adsorbs and purifies the liquid, and finally discharges it through the discharge pipe 27. When the purification plate 28 needs to be disassembled, the purification plate 28 is pulled, the block 30 leaves the slot 29, and then the purification plate 28 is removed for easy cleaning and replacement.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
