Description

TECHNICAL FIELD

[0002] Although the composting technology, which is one of the common disposal methods for household garbage, can avoid the generation of leachate, it is limited by the fact that the household garbage cannot be effectively sorted. Household garbage incineration for power generation can effectively dispose of household garbage and utilize the heat energy generated by incineration. However, like the sanitary landfill disposal method, the household garbage incineration for power generation also faces the problem of leachate treatment. Garbage leachate has been recognized as high-risk and high-pollution wastewater, and has great harmfulness to groundwater and surface water. How to reasonably treat it has become a difficulty and hotspot in the current environmental field research.

[0003] At present, leachate is generated during the incineration of household garbage. Since the household garbage incineration plant is a centralized incineration plant, some household garbage cannot be fully incinerated, so some un-fully-incinerated garbage is mixed in the leachate. Therefore, when the leachate biological reaction sewage treatment equipment is used to treat the leachate, some un-fully-incinerated garbage will float, which will easily block the filter screen in the pretreatment space of the leachate biological reaction sewage treatment equipment, thus reducing the filtering efficiency of the filter screen and affecting the working efficiency of the leachate biological reaction sewage treatment equipment.

[0035] The working principle and use process of the present application: before use, the workers first install the whole device at the designated position of the household garbage incineration plant, then connect the control valve drain pipe 26 with the drain pipe through the water pipe, at the same time, connect the control valve exhaust pipe 1 with the gas input port of the household garbage incinerator through the gas pipe, then insert the leachate discharge pipe of the household garbage incinerator into the first feeding groove 3, then the workers electrically connect the intelligent controller 5 with the external power supply, and complete the parameter setting work of the intelligent controller 5.

[0036] When in use, the workers pour the pretreated alkaline substance from the first feeding groove 3 into the pretreatment space, pour the deep treatment medicine from the second feeding groove 4 into the deep treatment space, after the leachate enters the pretreatment space, the alkaline substance in the pretreatment space will adjust the pH value of the leachate and complete the preliminary precipitation work, and in the pretreatment process, the workers operate the intelligent controller 5, so that the intelligent controller 5 controls the first servo motor 2, the second servo motor 12 and the four annular contact switches 33 to work.

[0037] When the first servo motor 2 works, it drives the second through-hole square column 35 to rotate, and when the second through-hole square column 35 rotates, it drives the first through-hole square column 11 and the L-shaped connecting lug 10 to rotate, and when the L-shaped connecting lug 10 rotates, it drives the two first through-hole square columns 11, the fishing assembly, the two first T-shaped round rods 15, and the two T-shaped sleeve columns 28 to move, so that the two T-shaped sleeve columns 28 reciprocate on the outer wall of the two second round rods 34, and in the process of moving, the extension and contraction of the spring 9 drive the second T-shaped round rod 29 to slide up and down in the second through-hole square column 35, thereby driving the L-shaped connecting lug 10 to move up and down, and when the L-shaped connecting lug 10 moves up and down, it drives the two first through-hole square columns 11 and the fishing assembly to move up and down, so that the two first through-hole square columns 11 slide up and down on the outer wall of the two first T-shaped round rods 15, thereby enabling the fishing assembly to perform reciprocating rectangular motion, facilitating the fishing assembly to fish for floating and incompletely combusted garbage;

[0038] In addition, in the process of moving, when the two ring-shaped contact switches 33 on the front side contact the two fixed square columns 8 on the front side, the intelligent controller 5 controls the first servo motor 2 to rotate forward, and when the first servo motor 2 rotates forward, it drives the first bevel gear 36 to rotate forward, and since the first bevel gear 36 is engaged with the second bevel gear 37, the first bevel gear 36 drives the second bevel gear 37 to rotate in reverse, thereby driving the first round rod 32 to rotate in reverse, so that the J-shaped filter screen 14 rotates upward by 30°, facilitating the J-shaped filter screen 14 to fish for floating and incompletely combusted garbage on the front side, and when the two ring-shaped contact switches 33 on the rear side contact the two fixed square columns 8 on the rear side, the intelligent controller 5 controls the first servo motor 2 to rotate in reverse, so that the J-shaped filter screen 14 rotates downward by 30° and returns to the initial position, thereby facilitating the J-shaped filter screen 14 to fish for floating and incompletely combusted garbage and facilitating the J-shaped filter screen 14 to deliver the fished floating and incompletely combusted garbage to the inside of the collection box 27 for storage;

[0039] When the pretreated liquid passes through the separation filter screen 16, the separation filter screen 16 performs filtering work, and after the filtering is completed, the liquid enters the inside of the deep treatment space, at which time the deep treatment medicine fully reacts with the filtered liquid, and in the process of full reaction, the macromolecular organic substances existing in the liquid are adsorbed or decomposed, thereby achieving a large degree of degradation of COD or hydrolytic acidification into small-molecule organic substances that are easy to degrade, and producing biogas, and at this time, the biogas is delivered to the inside of the household garbage incinerator through the control valve exhaust pipe 1 to assist combustion;

[0040] After the reaction work and the secondary precipitation are fully completed, the staff operates the intelligent controller 5, and the intelligent controller 5 controls the water pump 22 to work. At this time, the reaction liquid in the deep treatment space is sucked into the precipitation space through the water suction pipe 20, the protection water inlet column 18 and the protection water outlet column 23, and the three times of precipitation work are completed in the precipitation space. In the process of precipitation, the upper liquid is relatively clean water. When the relatively clean water in the upper layer flows over the activated carbon filter plate 25, the activated carbon filter plate 25 adsorbs and filters the small substances in the liquid, so that clear and clean water is obtained. The clear and clean water flows into the clean water storage space for storage. Then, the clear and clean water is discharged through the control valve drain pipe 26 and the drain pipe.

[0041] After the biological reaction of the leachate is completed, the staff can take out the collection box 27 containing the garbage from the square slot 71. Finally, the staff can transport the collection box 27 containing the garbage to the household garbage incinerator, and pour the garbage in the collection box 27 into the household garbage incinerator again for incineration.

[0042] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
