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 purifying system 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.

Technical field
The present invention relates to a kind of sewage disposal equipment, relate in particular to a kind of ecological soil purifying bed with automatic domestic sewage reoxygenation function.
Background technology
Development of Small Cities and Towns is rapid in China, and there are more than 20,000 of middle samll cities and towns in China at present, but the sanitary sewage disposal rate of middle samll cities and towns is less than 1%, estimates that the sanitary sewage of China more than 80% will be from medium and small cities and towns from now on.Therefore, the medium and small town sewage technology of developing a kind of suitable China's national situation becomes China scientific worker's a important subject.
At present, China's overwhelming majority municipal wastewater treatment plant all adopts traditional secondary activated sludge method processing technique.This technology investment height, energy consumption is big, and operational management requires also high.Because China's level of economic development is not high, energy shortage, many places especially small and medium-sized cities lack the personnel with certain operational administrative experience and state of the art with the rural area, township and village enterprises's fast development of China simultaneously, therefore the serious environmental pollution has been caused in the locality, developed energetically in China and have sewage disposal technology efficient, simple and easy, low consumption and have very big meaning
The soil treatment system of sewage safeguards that with its simple structure capital cost and running cost are cheap easily, and the characteristics such as the energy and resource of saving are subjected to broad development.
At present common sanitary sewage soil treatment technology and shortcoming thereof are as follows:
(1) sewage sand filtration treatment system.General employing back-up sand allows sewage discharge system through the sand body diafiltration as medium, reaches the purification purpose.Shortcoming mainly is that hydraulic load is lower, and processing power is little.
(2) septic tank+soil cut-off filter.Using in states such as America and Europes of this class reactor is more, and domestic application is less.But it exists floor space big too, shortcomings such as running maintenance difficulty.
(3) association type soil ecology treatment system.This class reactor combines the advantage of soil and biochemical treatment to a certain extent.But because the biochemical reaction overlong time, running cost is higher, and because equipment is more, complex management.
