Description

Technical Field

[0001] This utility model belongs to the field of livestock farm manure treatment technology, and particularly relates to pig manure composting equipment. Background Technology

[0002] In modern animal husbandry, large-scale pig farms, as important production units, generate large amounts of wastewater daily. The discharge of this wastewater is strictly prohibited, as it not only emits foul odors and impacts the surrounding environment, but also poses significant environmental and legal risks due to illegal discharge. Therefore, wastewater management has become a pressing issue. Many farms, due to inadequate environmental protection facilities, primarily rely on oxidation ponds (storage tanks) to store and treat wastewater. However, the main problem with existing oxidation ponds is the high ammonia nitrogen content, which necessitates dilution before returning the wastewater to the fields, resulting in reduced wastewater volume per acre and high treatment costs.

[0019] like Figure 1-6 As shown, the pig manure composting equipment includes a reactor 1, with an inlet pipe 12 and an outlet pipe 11 connected to the reactor 1. Both the inlet pipe 12 and the outlet pipe 11 are equipped with flow controllers 13 to control the amount of wastewater entering and leaving the reactor 1, achieving an inflow-outflow balance. The equipment also includes an aeration assembly, a stirring assembly, a waste gas treatment assembly, a microbial agent filling assembly, and a sampling assembly. The aeration assembly is used to aerate the reactor 1 by introducing external air into the reactor 1, ensuring sufficient oxygen levels within the reactor 1, suitable for aerobic decomposition by the compound microorganisms, converting ammonia nitrogen gas into nitrate nitrogen, which is beneficial for agricultural use. The reactor is used for crop nutrient absorption; the stirring component is used to mix the wastewater in reactor 1. Each time new wastewater is introduced or microbial agents are added, it needs to be stirred evenly to ensure better fermentation; the exhaust gas treatment component is used to treat the exhaust gas discharged from reactor 1 to avoid excessive pressure in reactor 1 after each aeration, and to remove odors to prevent air pollution; the microbial agent filling component is used to replenish the compound microbial bacteria in reactor 1; the sampling component is used to periodically sample the wastewater in reactor 1 to test the seed germination rate, ensuring that the ammonia nitrogen conversion rate in the fermented wastewater meets the standard and is suitable for seed growth.

[0020] Furthermore, the aeration assembly includes an aeration pipe 2, which is located on the inner wall of the reactor 1. The aeration pipe 2 is arranged in a closed loop along the four walls of the reactor 1 in the circumferential direction, and multiple sets of aeration pipe 2 are arranged in the longitudinal direction. The aeration pipe 2 is provided with aeration holes. The aeration pipe 2 extends out of the reactor 1 and is connected to a valve 7. Multiple sets of valves 7 are connected through a first pipe 22. The other end of the first pipe 22 is connected to a blower 23. The blower 23 is located at the top of the reactor 1 and introduces air into the waste liquid in the reactor 1 through airflow. The appropriate valve 7 is selected to open for aeration according to the liquid level of the waste liquid in the reactor 1 to avoid ineffective aeration.

[0021] Furthermore, the stirring assembly includes a rotating shaft 3, which is rotatably disposed inside the reactor 1 and rotatably connected to the left and right side walls of the reactor 1. The side of the rotating shaft 3 is provided with stirring rods 31 and stirring plates 32, which are arranged crosswise in the circumferential direction. Multiple stirring rods 31 are provided along the axial direction of the rotating shaft 3 and are evenly arranged in a linear array. One end of the rotating shaft 3 extends out of the reactor 1 and is connected to a drive motor 33, which is disposed on the side wall of the reactor 1. Multiple drainage holes 34 are provided through the stirring plates 32 along the axial direction of the rotating shaft 3. Multiple sets of stirring assemblies can be provided and evenly arranged in the longitudinal direction. The stirring rods 31 stir the waste liquid, and the stirring plates 32 have a larger area, which can more fully stir the waste liquid, thereby making the waste liquid at the top and the waste liquid at the bottom better mixed.

[0022] Furthermore, the microbial agent filling component includes an insulated tank 5, which contains a microbial culture solution containing the required compound microbial strains. The compound microbial strains are a facultative anaerobic compound microbial agent, and the main raw materials include Bacillus, lactic acid bacteria, yeast, nitrifying bacteria, photosynthetic bacteria, Bacillus thuringiensis, flocculants, and cyanobacteria-inhibiting bacteria, etc., which are used to convert ammonia nitrogen in the waste liquid into nitrate nitrogen. The tank is connected to a water pump 51, and the water pump 51 is connected to a nozzle 52 through a hose 53. The nozzle 52 extends into the reactor 1 and is located at the top of the reactor 1. The activated compound microbial strains can be delivered into the reactor 1 by the water pump 51 and sprayed onto the waste liquid. The waste gas treatment component includes a treatment box 4, which is located on top of the reactor 1. A vent pipe 41 is provided between the treatment box 4 and the reactor 1, and a pressure valve 42 is provided on the vent pipe 41. Activated carbon is provided inside the treatment box 4. An exhaust port is provided on the treatment box 4. The composite microorganisms can effectively convert the ammonia nitrogen generated by the waste liquid. The content of harmful gases in the waste gas is low and meets the emission standards. Deodorization can be achieved through activated carbon.

[0023] Furthermore, the sampling component includes a constant temperature petri dish 6, which is connected to the reactor 1 via a sampling tube 61. The sampling tube 61 is equipped with a valve 7 and is located at the bottom of the reactor 1. A placement plate 62 is pulled out from the bottom of the constant temperature petri dish 6. One side of the constant temperature petri dish 6 has a transparent observation window. The placement plate 62 holds treated seeds for testing. Waste liquid is collected periodically, such as once a week or once every two weeks, for seed cultivation and germination rate testing, thereby ensuring that the nitrate nitrogen in the treated waste liquid meets the standard and has a good promoting effect on crops.

[0024] The working principle of this invention is as follows: Before commissioning, wastewater of 1 / 5 of the reactor's volume is added to the reactor 1 through the feed pipe 12. Then, 1 / 30 of the volume of the activated compound microbial agent in the insulated tank 5 is added to the reactor 1 through the water pump 51. The bottom stirring component is started to mix thoroughly, then stirring is stopped, and valve 7 of the bottom aeration pipe 2 is opened for aeration. After that, 1 / 5 of the solvent wastewater is added every 48 hours. After adding, the corresponding stirring component is started to stir, and then the reactor is left to stand and aerated. After ten days, the reactor 1 is full. After two days of static aeration, wheat or corn seeds are placed on the placement plate 62 through the sampling component. The treated wastewater in the reactor 1 is introduced through the sampling tube 61 to measure the seed germination rate. If the germination rate reaches 70% or higher, it is considered qualified and can be put into use. At this time, 1 / 10 of the wastewater is discharged and 1 / 10 of the wastewater is fed in, alternating in a cycle to achieve stable operation of reactor 1. The seed germination rate is tested periodically. If it is unqualified, bacterial agent is added. During this process, if the pressure difference between the gas pressure inside reactor 1 and the external gas pressure reaches a certain value, the pressure valve 42 is activated to discharge the waste gas inside reactor 1 after purification through treatment box 4. Compared with the traditional fermentation which takes 15-20 days, this equipment can treat wastewater and put it into use for crops in only 12 days, without the need for further dilution. It effectively solves the problem of high ammonia nitrogen content in waste gas, has a short fermentation time, and can periodically monitor the use of waste liquid, which better ensures that the treated waste liquid is easy for crops to absorb.

[0025] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
