Abstract

Abstract: In order to study rural domestic sewage treatment technology, a rapid infiltration and wetland integrated system was established in Xi'an Village, Lingtian Town, Lingchuan County, Guilin City, and the NH₃-N, TN, TP, and COD were monitored from April 2019 to April 2020. Pollution removal effect, the relationship of removal effect between temperature and season. The results showed that the system had obvious removal effects on NH₃-N, TN, TP and COD in rural domestic sewage, and the removal rates were 87.75%, 78.88%, 93.94% and 89.24%. The sewage discharge complies with the first level type A standards of GB 18918—2002. The removal rates of NH3-N, TN, TP and COD were significantly positively correlated with air temperature at the level of 0.01, and COD was greatly affected by air temperature. The removal effect of NH3-N, TN, TP and COD in flat water period was better than that in high water period and better than that in low water period.

Key words: rapid infiltration, biological wetland, rural domestic sewage treatment, correlation
