Ecologically harmless treatment system of excrement and domestic sewage

Abstract

The invention discloses an ecologically harmless treatment system of excrement and domestic sewage. The treatment system mainly comprises a septic tank, wherein, the septic tank is connected with a silting acidification tank, an anaerobic fermentation tank and an ecological treatment tank in sequence through a connecting pipe of a box body; the septic tank, the silting acidification tank and the anaerobic fermentation tank are provided with respective upper covers; and an elastic filler is arranged in the anaerobic fermentation tank. Based on the design of the tanks, the tanks can effectively treat the excrement, and the discharged sewage after the treatment can meet the second-class standard of the state. The first two tanks of the treatment system perform the fermenting and sterilizing functions and the septic function; the last four tanks are the silting acidification tank, the anaerobic fermentation tank, a filtering wetland tank and a water outlet tank. The treatment system utilizes anaerobe to ferment and decompose organic matters, and promotes the decomposition of facultative microorganism through the filtration, root interception, sorption, absorption, and photosynthesis and oxygen transportation of plants, so as to efficiently purify the sewage.

Description

technical field [0001] The invention relates to a treatment system for feces and domestic sewage, in particular to a treatment system for ecologically harmless feces and domestic sewage. Background technique [0002] Existing rural feces treatment often uses the form of open-air huts. The feces are naturally reacted in the septic tank and then applied to farmland for fertilization. However, with the development of the countryside, most of the buildings are built and abandoned. The treatment of feces and sewage has brought difficulties, because the rural area occupies a vast area, and it is still impossible to form a comprehensive and effective feces and sewage treatment system. It is still necessary for each household to solve the problem of feces and sewage by itself. In most cases, the sewage will be directly discharged into the The surrounding small rivers directly affect the surrounding ecological environment. However, the cost of a system that can effectively treat fec...

[0002] Existing rural feces treatment often uses the form of open-air huts. The feces are naturally reacted in the septic tank and then applied to farmland for fertilization. However, with the development of the countryside, most of the buildings are built and abandoned. The treatment of feces and sewage has brought difficulties, because the rural area occupies a vast area, and it is still impossible to form a comprehensive and effective feces and sewage treatment system. It is still necessary for each household to solve the problem of feces and sewage by itself. In most cases, the sewage will be directly discharged into the The surrounding small rivers directly affect the surrounding ecological environment

However, the cost of the system that can effectively treat feces and domestic sewage is relatively high, and it cannot meet the needs of every household to use this system
