Efficient and stable domestic sewage ecological treatment device and operation method

Abstract

The invention relates to an efficient and stable domestic sewage ecological treatment device and an operation method and belongs to the field of sewage treatment of environmental engineering. The efficient and stable domestic sewage ecological treatment device comprises a soil layer, a water distribution layer, a magnetic layer, a gravel layer and a water collection layer from top to bottom and further comprises a water distribution and collection system; the water distribution and collection system comprises water inlet pipes and water collection pipes; the water inlet pipes include a water inlet main pipe and a plurality of water inlet branch pipes, the water inlet main pipe is connected with a water pipe entering the ecological treatment device, the multiple water inlet branch pipes areperpendicularly connected with the water inlet main pipe respectively and located at the water distribution layer, the water inlet branch pipes include the upper-layer water inlet branch pipes and the lower-layer water inlet branch pipes, and sewage enters the water inlet main pipe, the upper-layer water inlet branch pipes and the lower-layer water inlet branch pipes in sequence; the water collection pipes include a water collection main pipe and a plurality of water collection branch pipes, and the multiple water collection branch pipes are perpendicularly connected with the water collectionmain pipe and located in a bottom groove; and the lower-layer water inlet branch pipes and the lower-layer water collection branch pipes are provided with a plurality of air inlet pipes respectivelyfor being communicated with the outside atmosphere, and the treated sewage flows from the water collection branch pipes into the water collection main pipe and then is discharged. The sewage is distributed uniformly, and the treatment efficiency is high.

Description

technical field [0001] The invention belongs to the field of environmental engineering sewage treatment, and in particular relates to an efficient and stable domestic sewage ecological treatment device and an operation method. Background technique [0002] In the process of building a new socialist countryside, in order to further improve the rural living environment, rural dry toilets have been transformed, but the treatment and disposal of septic tank effluent after transformation has become a major problem. The low treatment capacity of domestic sewage in rural areas of our country has led to rural domestic sewage becoming one of the important sources of surface water environmental pollution. In the current rural areas, the pipe network coverage is low, the sewage treatment facilities are not perfect, and the centralized domestic sewage treatment method cannot be applied to the current situation in rural areas. The use of decentralized domestic sewage treatment technology...
