Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for co-producing carbon sources through hydrolysis and acidification of kitchen waste and denitrification of wastewater. Background Technology

[0002] Food waste, including food scraps and waste oil, is organic waste generated from daily life and catering services. Its characteristics and the limitations of traditional treatment methods are the primary reasons for the emergence of co-processing technologies. When treating food waste, a device is needed to hydrolyze and acidify food waste to produce a carbon source while simultaneously denitrifying wastewater. This technology controls anaerobic reaction conditions to convert large organic molecules in food waste into volatile fatty acids that are easily utilized by denitrifying bacteria. This not only solves the problems of reducing and recycling food waste but also provides a high-quality, low-cost carbon source for wastewater denitrification.

[0003] Current equipment for the co-production of carbon sources from the hydrolysis and acidification of kitchen waste and the denitrification of wastewater still has some problems, as follows: Before denitrification, the hydrolyzed and acidified kitchen waste needs to be filtered to reduce impurities in the wastewater. Utility Model Content

[0004] The purpose of this invention is to provide a device for the co-production of carbon source from the hydrolysis and acidification of kitchen waste and the denitrification of wastewater, in order to solve the defect of existing devices for the co-production of carbon source from the hydrolysis and acidification of kitchen waste and the denitrification of wastewater that are difficult to filter kitchen waste.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for co-producing carbon source through hydrolysis and acidification of kitchen waste and denitrification of wastewater, including a base;

[0006] A support leg is installed on one side of the top of the base, and a housing is installed on the top of the support leg. A water inlet is installed on the top of the housing, and an anaerobic pump is installed on the top of one side of the housing.

[0007] A connecting pipe is installed at the bottom end of one side of the housing, and a pump body is installed on the outside of the connecting pipe. A housing is installed on one side of the connecting pipe, and a water outlet is installed at the bottom end of one side of the housing.

[0008] A filter mechanism is installed at the top of the interior of the housing. The filter mechanism includes a hydraulic cylinder installed at the top of the housing, and a pressure plate is installed at the bottom of the hydraulic cylinder. A guide rail is installed inside the housing.

[0009] In use, kitchen waste is first loaded into the shell through the inlet. The heating wire keeps the temperature inside the shell at a suitable level. After the inlet is closed, additives are loaded into the shell through the outlet. After the reaction is complete, the pump works to draw the kitchen waste into the shell through the connecting pipe. After solid-liquid separation, the wastewater falls to the bottom of the shell. Then, by adding additives such as nitrates, the wastewater can react into nitrogen gas, completing the denitrification reaction.

[0010] Furthermore, an installation block is installed at the top of the guide rail, a filter screen is installed inside the installation block, a handle is installed on one side of the installation block, and a guide rod is installed at the top of the pressure plate. The installation block can slide into the housing, and the filter screen can filter kitchen waste.

[0011] Furthermore, a sliding groove is provided at the top of the guide rail, and a slider is provided at the bottom of the mounting block. The guide rail and the mounting block form a sliding structure, and the mounting block can slide along the guide rail.

[0012] Furthermore, a heating wire is embedded at one end inside the housing, and the heating wire is in the shape of an "S" to keep the inside of the housing warm.

[0013] Furthermore, a stirring structure is installed inside the shell. The stirring structure includes a stirring shaft installed inside the shell, stirring blades installed on the outside of the stirring shaft, and an impeller installed at the top of the stirring shaft. The stirring structure can stir the kitchen waste.

[0014] Furthermore, a connecting structure is installed at the top of one side of the housing, and the connecting structure includes an inlet installed at the top of one side of the housing, a flange installed on one side of the inlet, a cover installed on one side of the flange, a screw installed on one side of the flange, and a nut installed on the outside of the screw. The connecting structure can be connected to different pipes.

[0015] Furthermore, the outer side wall of the screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The screw and the nut are threadedly connected, and the screw and the nut can fix the cover.

[0016] The advantages of the device for co-producing carbon source and denitrifying wastewater through hydrolysis and acidification of kitchen waste provided by this utility model are as follows:

[0017] By installing a hydraulic cylinder at the top of the outer shell, after the food waste is hydrolyzed and acidified, it enters the inner shell through the connecting pipe. The food waste can then be filtered through a filter screen. During filtration, the hydraulic cylinder operates, causing the pressure plate at the bottom to rise and fall. After the pressure plate presses down on the food waste, the wastewater is squeezed out and falls into the bottom of the outer shell through the filter screen, achieving solid-liquid separation. When the pressure plate rises and falls, the guide rod can guide the rise and fall of the pressure plate to prevent the pressure plate from deviating. This achieves the goal of using food waste hydrolysis and acidification to produce carbon source and simultaneously denitrify wastewater, making the equipment easy to filter food waste.

[0018] By installing a water inlet at the top of the shell, when wastewater from kitchen waste is poured into the shell through the inlet, the impact force of the wastewater will strike the impeller, causing the impeller to rotate. The rotation of the impeller will drive the stirring shaft to rotate, which in turn will drive the stirring blades to rotate. The rotation of the stirring blades can stir the kitchen waste inside the shell, allowing the kitchen waste to mix and react quickly with the internal additives, resulting in a better reaction effect. This achieves the purpose of accelerating the reaction speed of the equipment that promotes the production of carbon sources through the hydrolysis and acidification of kitchen waste and the denitrification of wastewater.

The kitchen waste can be filtered through the filter screen 206. During filtration, the hydraulic cylinder 201 will drive the pressure plate 203 at the bottom to rise and fall. After the pressure plate 203 presses down on the kitchen waste, the sewage can be squeezed out. The sewage will fall into the bottom of the outer shell 1 through the filter screen 206, realizing solid-liquid separation.
