Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. However, the scope of the present invention is not limited thereto.
[0015] The septic tank 1 is a three-format septic tank separated by a dividing plate 8. The sewage from the previous grid is introduced into the rear grid by the diversion pipe 9, and there is a cover plate on the top of the pool.
[0016] The aerobic reactor 2 is filled with soft biological fillers. The aerobic microorganisms in the aerobic reactor 2 are composed of bacteria gelatinous bacteria and filamentous bacteria. Part of the aerobic microorganisms grows in suspension, and the other part adheres to the surface of the soft biological fillers; The anaerobic reactor 3 is equipped with a porous suspension ball biological filler. The anaerobic microorganisms in the anaerobic reactor 3 are mainly composed of acid-producing bacteria and methanogens. Part of the anaerobic microorganism...

Abstract
The invention discloses an automatic oxygen-increasing processing method for living sewage of rural areas. The method comprises a septic tank (1), an aerobic reactor (2), an anaerobic reactor (3) and an artificial wetland (4) connected in series. The method increases the dissolved oxygen content in the aerobic reactor and the artificial wetland by an automatic oxygen-increasing mechanism comprising a special pipe (5), a hollow throat (6) and an air duct (7) under the situation of not consuming any power, and improves the removing efficiency of the aerobic reactor to contaminations, the denitriding efficiency of the artificial wetland and the capacity of removing other contaminations. The method can effectively solve the problem of random discharge of living sewage in the countryside, improve the ecological environment of the countryside, improve the living condition of the people in the countryside, guarantee the environmental health of the countryside, and promote the construction process of a new socialist countryside.
Description
1. Technical field [0001] The invention relates to a sewage treatment method, in particular to an automatic aeration treatment method for domestic sewage in rural market towns. 2. Background technology [0002] The rural areas of our country produce more than 8 billion tons of domestic sewage every year, and 96% of the villages have no drainage channels and sewage treatment systems, and domestic sewage is discharged at will. Domestic sewage in rural areas of our country has the following characteristics: wide and scattered; many sources; fast growth; low treatment rate. The indiscriminate discharge of domestic sewage in rural areas seriously pollutes the rural ecological environment and directly threatens the health of rural residents and the development of rural economy. Therefore, it is very important to control domestic sewage in rural market towns and improve the rural ecological environment. In 2006, the Central Committee of the Communist Party of China issued the "Se...
