[0002] Traditional sewage treatment methods include soil filter method and biological filter method.

[0003] The soil filter method is a process that utilizes microorganisms in the soil to convert malodorous substances into harmless or low-toxicity substances. This method typically involves passing malodorous gases into a soil layer containing abundant microorganisms that can degrade malodorous substances such as hydrogen sulfide, ammonia, etc. Generally, it is composed of an impermeable layer, a gravel cushion layer, a pipeline arrangement layer, a large cobblestone layer, a small cobblestone layer, a coarse sand layer, and an active soil layer from bottom to top. During use, a large amount of water needs to be sprayed. The advantages of the soil filter method are: simple operation, low cost, and the ability to remove multiple malodorous substances. However, its disadvantages are also quite obvious, including low processing efficiency, significant influence from weather conditions, risk of soil pollution, and wide land occupation. Due to the large number of underground pipeline networks in sewage plants, underground pipeline laying is difficult or even ineffective.

[0004] The biological filter method is a method that utilizes aerobic microorganisms to biologically oxidize and treat sewage or organic wastewater. Its advantages are good treatment effect, stable operation, and high automation level. However, it has disadvantages such as large land occupation and the need for the discharge outlet or discharge cylinder to protrude upwards, which not only affects the overall environmental layout but also is not aesthetically pleasing.
