Abstract
Description
Technical Field
[0001] This utility model relates to the field of deodorization devices, and more particularly to a deodorization device containing multi-stage biological deodorization. Background Technology
[0002] Biological deodorization equipment utilizes the biochemical action of microorganisms to decompose pollutants and transform them into harmless or less harmful substances. Microorganisms and bacteria use odor components as a substrate for their growth and reproduction, and through different transformation pathways, they oxidize and decompose large molecular or structurally complex malodorous pollutants into simple inorganic substances such as water and carbon dioxide through dissimilatory processes.
[0003] Currently available biological deodorization devices are usually quite complex in structure. During the pre-washing spraying process, pollutants in the gas dissolve in water and become molecules and ions in the liquid phase. The device requires an external water source, which cannot effectively save water resources. This greatly increases the production, manufacturing, and application costs of biological deodorization devices. Furthermore, the biological treatment layer is located in the device structure and is not easy to disassemble, making it impossible to replace the biological treatment layer in a timely manner and reducing the deodorization efficiency of the device.

[0032] Reference Figure 1-5This utility model provides an embodiment of a deodorization device with multi-stage biological deodorization, comprising a housing 1. The device is characterized by: an air inlet pipe 2 fixedly connected to the right end of the housing 1; an air collection tank 3 fixedly connected to one end of the outer side of the air inlet pipe 2; a water tank 4 disposed on one side of the front end of the housing 1; a water pump pipe 6 fixedly connected to the left end of the water tank 4; a pre-wash water pipe 5 fixedly connected to the top of the water tank 4; a plurality of biological pre-wash spray nozzles 7 fixedly connected to the bottom end of the pre-wash water pipe 5; a circulating water pump 8 disposed on one side of the rear end of the housing 1; an outlet pipe 9 fixedly connected to the top of the circulating water pump 8; the bottom end of the outlet pipe 9 penetrating the inner wall of the top of the housing 1 and fixedly connected to a connecting pipe 11; and a plurality of biological treatment spray nozzles 12 fixedly connected to the bottom end of the connecting pipe 11. A suction pipe 13 is fixedly connected to one end of the circulating water pump 8, and a partition 14 is fixedly connected to one end of the inner side of the housing 1. Odors enter the biological pre-washing stage from the gas collection tank 3 through the air inlet pipe 2. Water is provided through the water tank 4, and water enters from the pre-wash water pipe 5. During the pre-washing spraying process, pollutants in the gas dissolve in water and become molecules and ions in the liquid phase, thereby changing the odor from the gas phase to the liquid phase. The circulating water pump 8 absorbs the liquid phase and releases it from the biological treatment spray head 12. After purification by the biological treatment layer, harmful substances are absorbed, and the liquid phase becomes ordinary water that enters the water collection tank 10. The purified water is absorbed by the water tank 4, completing one water cycle, thus achieving the purpose of saving resources and reducing operating costs.
[0033] Several slide rails 15 are fixedly connected to one end of the inner side of the tank 1 and one end of the outer side of the partition 14. An activated carbon layer 16 is slidably connected to one end of each slide rail 15, a primary biological treatment layer 17 is slidably connected to one end of each slide rail 15, and a secondary biological treatment layer 18 is slidably connected to one end of each slide rail 15. The primary and secondary biological treatment layers 17 and 18 are filled with materials such as crushed stone, coke, slag, or artificial filter media, and are fully supplied with oxygen and nutrients. Wastewater is then sprayed onto these layers in a drip-like manner. At this time, a gel-like biofilm will form on the surface of the filter media. When the wastewater seeps down along the biofilm, soluble... Colloidal and suspended substances are adsorbed onto the biofilm and oxidized and decomposed by microorganisms. Pull plates 19 are fixedly connected to the front ends of the activated carbon layer 16, the primary biological treatment layer 17, and the secondary biological treatment layer 18, which allows for timely installation and removal of the activated carbon layer 16 and the biological treatment layer, and facilitates observation of microbial activity. Filter holes 21 are provided in the activated carbon layer 16, the primary biological treatment layer 17, and the secondary biological treatment layer 18. An air outlet pipe 20 is fixedly connected to the top left side of the box body 1. An exhaust fan is installed inside the air outlet pipe 20. A water pump is installed inside the water tank 4. A water collection tank 10 is installed inside the box body 1.
[0034] Working principle: Water is supplied through water tank 4 and enters through pre-wash water pipe 5. During the pre-wash spraying process, pollutants in the gas dissolve in the water and become molecules and ions in the liquid phase, thus changing the odor from the gas phase to the liquid phase. The liquid phase is absorbed by the circulating water pump 8 and released from the biological treatment nozzle. The wastewater is purified through activated carbon layer 16, primary biological treatment layer 17 and secondary biological treatment layer 18. When the sewage seeps down along the biofilm, soluble, colloidal and suspended substances in the sewage are adsorbed on the biofilm and oxidized and decomposed by microorganisms. After purification by the biological treatment layer, harmful substances are absorbed, and the liquid phase becomes ordinary water that enters the collection tank 10. The purified water is absorbed by water tank 4, completing one water cycle, saving water resources and reducing operating costs.
