[0002] Water resources in arid mountainous areas are very scarce. There are a large number of farmlands that can absorb the treated sewage. The landforms are mostly mountainous, and flat land resources are limited. Villages tend to be located in relatively flat areas, so the residents of the villages live relatively concentratedly, and the construction land resources that can be used for sewage treatment in the village are limited. At the same time, the scattered distribution of villages and the weak local financial investment capacity have led to the inability of arid mountainous areas to adopt a centralized treatment model to treat domestic sewage like cities.

[0003] When the existing sewage treatment equipment is in use, the methane and other gases generated inside it are usually discharged through the holes on its surface or installed with an exhaust pipe. The discharge speed is slow, and it is easy to explode when it is not discharged in time and comes into contact with open flames. In addition, the existing parallel devices occupy a large surface area, the brick-stacked devices have poor stability and are easy to break and leak, the surface has poor pressure resistance, and it is inconvenient to move. The people in the arid mountainous areas do not accept it very much. Therefore, there is an urgent need for a domestic sewage treatment device that occupies a small surface area, discharges methane and other gases in time, is economical and affordable, is pressure-resistant and durable, and the treated sewage can be used for farmland irrigation to mobilize the enthusiasm of the people in the arid mountainous areas to treat domestic sewage.
