Ecological soil purifying bed with automatic domestic sewage reoxygenation function

Abstract

The invention discloses an ecological soil purifying bed with automatic domestic sewage reoxygenation function, which consists of a sewage lifting system, a sewage automatic reoxygenation device, a water distribution system, an ecological soil purifying system and a water outlet sterilizing system. When the ecological soil purifying bed with the automatic reoxygenation of the domestic sewage is used, the domestic sewage enters a water quantity adjustment pond after large-grain pollutants of the domestic sewage which comes from a septic tank are removed by grates in the sewage lifting system; then after being lifted by a sump pump, the domestic sewage with large-grain pollutants removed enters a water distribution pipe of the water distribution system through the automatic reoxygenation device; after being uniformly distributed, the domestic sewage enters a perforation water distribution pipe; and the domestic sewage which is uniformly drained from the perforation water distribution pipe is downward permeated in the soil purifying system. After being collected by a water collecting pipe at the bottom of the ecological soil purifying bed, the domestic sewage treated by the purifyingsystem is drained into a water outlet sterilizing pond, and after being sterilized, the domestic sewage is drained off, wherein the sterilizing pond is internally provided with a sterilizing medicament inputting device. The ecological soil purifying bed has the advantages of convenient management, stable treatment effect, low operation cost, high purifying effect, and the like.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an automatic reoxygenation domestic sewage ecological soil purification bed. Background technique [0002] my country's small and medium-sized towns are developing rapidly. At present, there are more than 20,000 small and medium-sized cities and towns in my country, but the domestic sewage treatment rate of small and medium-sized cities and towns is less than 1%. It is estimated that more than 80% of domestic sewage in my country will come from small and medium-sized cities and towns in the future. Therefore, the development of a small and medium-sized urban sewage process suitable for my country's national conditions has become an important research topic for Chinese scientists. [0003] At present, the vast majority of urban sewage plants in my country adopt the traditional secondary activated sludge treatment process. This process requires high investment, high energy consumption...
