Embodiment 1

[0054] Such as Figure 1~2 The shown kitchen waste leachate treatment device includes a body 1, a solar collector 2 arranged on the top of the body 1, a material inlet 3 and a solar panel 24; the material inlet 3 is arranged at one end of the top of the body 1 , and the other end is respectively provided with adjacent solar collectors 2 and solar panels 24; the inside of the body 1 is respectively a waste liquid tank 4, a biological treatment layer 5, a biochemical purification layer 6 and a purification liquid storage tank from top to bottom. Slot 9, as in figure 2 shown.

[0055] The waste liquid tank 4 communicates with the lower channel of the material inlet 3 through the filter screen 28; the bottom of the waste liquid tank 4 is provided with a water filter pipe 15 and a heat pipe 16, and the water filter pipe 15 is connected to the water inlet of the evaporator 14 and the cleaning pipe 20 respectively. First branch pipe 21; heat pipe 16 is connected with solar heat co...

Embodiment 2

[0068] Compared with Example 1, the difference of the kitchen waste leachate treatment device of this example is:

[0069] Described cultivation dish 17 is as Figure 5-7 As shown, the air intake groove 1701 is provided with an air inlet 1702 through the plate body, a layer of grid 1705 is provided in the culture plate 17, and a removable inserting plate 1707 is provided at the bottom.

[0070] The grid 1705 can make the worm sand in the breeding tray 17 fluffy, so that the air can enter the worm sand inside through the air inlet 1702, and improve the breeding efficiency of the black soldier fly; Drops in sand filling sieve 1706.

[0071] In the method of using the device in this embodiment, the method for separating insect sand and black soldier flies in step S4 is: after pulling out the insertion plate 1707 at the bottom of the culture tray 17, shake the culture tray 17 so that the insect sand in the tray passes through the sieve holes 1706 to drop Fall into the biochemica...

Embodiment 3

[0073] Compared with Embodiment 2, the difference of the kitchen waste leachate treatment device of this embodiment is:

[0074] The biological treatment layer 5 is as Figure 8 As shown, the left and right are divided into a breeding area and a separation area, which are separated by a partition plate 34 in the middle, and the separation area is provided with a separation drum 31; The end is arranged on the lower part of the inclined plane of the storage bin 12, the discharge end is arranged on the lower part of the partition plate 34 and is located on the upper part of the culture plate 17; the wall of the separation drum 8 is evenly distributed with through holes 33, and the rotating shaft is provided with helical blades along its axial direction. 32 ; the motor 30 is arranged in the upper part of the storage bin 12 .

[0075] The bottom of the separation roller 31 is also provided with a second evaporator 36, which is arranged on the lower part of the culture tray 17 near...

Abstract

The invention provides a kitchen waste percolate treatment device and a using method thereof. The kitchen waste percolate treatment device is internally provided with a waste liquid tank, a biologicaltreatment layer, a biochemical purification layer and a purified liquid storage tank from top to bottom. According to the invention, kitchen waste is subjected to solid-liquid separation, separated percolate enters the waste liquid tank, and separated materials enter the biological treatment layer for mixing with semi-mature fertilizer to culture hermetia illucens; the percolate in the waste liquid tank is heated by an evaporator and is used for humidifying and heating materials in the biological treatment layer; and cultured insect sand is treated again by mature fertilizer and activated carbon to obtain purified water, and the purified water can be used for cleaning the device. According to the kitchen waste percolate treatment device, the kitchen waste percolate and residues can be effectively separated, the separated residues are used for culturing hermetia illucens, the percolate is recycled for fumigation sterilization, increasing a hermetia illucens culture temperature and increasing the nutrient content of compost, and the utilization rate of kitchen waste is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a kitchen garbage leachate treatment device and a use method thereof. Background technique [0002] Kitchen waste (commonly known as swill, swill) is a general term for food waste and kitchen waste. Kitchen waste refers to the leftovers and leftovers discarded in the daily cooking of residents. Among them, food waste comes from restaurants, canteens and other commercial and The leftovers produced by public institutions are generally not suitable for direct composting and returning to the field due to their high salt and oil content. The mixed food waste is generally not suitable for direct composting treatment. The existing treatment methods are direct landfill or incineration, which leads to poor utilization of nutrients and waste. Food waste is rich in nutrients. A new treatment method is to use black soldier flies to process food waste to obtain black so...
