[0002] Domestic sewage mainly includes toilet flushing sewage and wastewater from laundry, rice washing, vegetable washing and bathing, and has a low pollution level. If it is treated centrally, the cost will be high. However, the decentralized sewage treatment system has the characteristics of low investment, simplicity, stability and convenient maintenance and management. It is convenient for treating household sewage discharge and is the preferred model for rural domestic sewage treatment.

[0003] After searching, Chinese patent CN106927575B discloses an artificial wetland sewage treatment device.

Its overall structure is simple and compact, which can be suitable for installation in a single household in rural areas. It has low cost. The sewage buffer tank can make domestic sewage be cached and retained in the sewage buffer tank for a period of time, and then a water distribution system with adjustable water inlet is formed through the lifting grille plate. On the one hand, the grille water inlet hole is The setting can achieve uniform distribution of domestic sewage in the matrix layer of the sewage treatment pool, thereby improving the utilization efficiency of the sewage treatment pool. On the other hand, the grille plate and the grille water inlet hole can more conveniently intercept domestic garbage. Users only need to simply clean the sewage buffer pool, which will not affect the subsequent sewage treatment pool, greatly improving the service life of the device; and according to the daily drainage volume of the household, the water inlet height of the grille plate is adjusted, that is, the water inlet height of the grille water inlet hole is changed, and the water inlet volume is adjusted, so that domestic sewage can fully react in the sewage treatment pool without flowing quickly, thereby improving the sewage treatment effect.
