Abstract

The invention provides a rural domestic sewage self-driven landscape ecological treatment method and system. The system comprises an automatic control system, a sewage detection device, and a dosing device; the automatic control system is electrically connected with a solar power supply device; the sewage detection device is electrically connected with the automatic control system; the sewage treatment device comprises a water collecting tank, a Biochemical adjusting tank, an A / O biochemical tank, a same-position nitrification denitrification filter bed, a discharge tank and a variable-frequency controller; the automatic control system is electrically connected with the automatic control system; the frequency conversion controller is electrically connected with the automatic control system; and the dosing device is electrically connected with the automatic control system. According to the method and the system, the residence time of rural domestic sewage in the biochemical treatment process is greatly shortened, the problem that rural domestic sewage is difficult to treat is solved, the effluent quality is stable and up to the standard, the later maintenance application cost is low, the occupied area is small, the operation efficiency is improved, and the cost is reduced; meanwhile, landscape plants are loaded on the filter bed, nutrient substances in the sewage can be absorbed, the landscape plants are capable of being matched with a rural environment landscape, and the landscape plants are free of foul smell and can meet the construction requirements of the rural environment.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a treatment method and system for self-driven landscape ecologicalization of rural domestic sewage. Background technique [0002] So far, the data show that there are 200 million rural households in my country, nearly 800 million people. Since it began to appear in the 1980s, the plight of rural water pollution has lasted for many years and has become more and more serious. Rural sewage mainly has the following characteristics: ① Relatively scattered and small water volume. Generally, rural households live in a scattered manner, and the number of single households is relatively small. The amount of domestic sewage produced is also small, and the concentration of pollutants in domestic sewage is also low. ② Large coefficient of variation. The life patterns of the villagers are relatively consistent. The discharge of sewage in the morning, noon, and evening is ...
