Domestic sewage treatment equipment with biological fluidized bed and biological aerated filter

Abstract

The invention provides domestic sewage treatment equipment with a biological fluidized bed and a biological aerated filter. The domestic sewage treatment equipment comprises a biological fluid bed contact oxidation area, a hydrolytic acidification area, a central flow guide type settling area, a biological fluid bed aeration filter area, a sand filter area, a clear water area and an equipment room which are arranged in sequence. Water flows through the hydrolytic acidification area, the central flow guide type settling area, the biological flow bed aeration filtering area, the sand filter area and the clear water area from the biological flow bed contact oxidation area and then is discharged; the hydrolytic acidification area is communicated with the outer side space of the central flow guide type settling area; and the equipment room is located at the tail of the whole sewage treatment equipment. According to the domestic sewage treatment equipment with the biological fluidized bed and the biological aerated filter, the domestic sewage treatment equipment is divided into the single functional areas, and when the domestic sewage treatment equipment is used, the single functional areas are combined together, so that the domestic sewage treatment equipment is convenient to transport and mount, and meanwhile, the infrastructure land occupation of infrastructure is reduced; and the occupied area is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to domestic sewage treatment equipment for a biological fluidized bed aerated biological filter. Background technique [0002] In view of the scattered living in rural areas, although there is centralized renovation, the cost of the pipe network is high, and the laying of the pipe network depends on the actual situation, and it cannot reach 100% full coverage; at present, the rural sewage treatment part is built with septic tanks ), but it is only treated by septic tanks (sewage tanks), and the quality of the effluent water cannot meet the discharge standards. [0003] The existing sewage treatment facilities occupy a large area, are not easy to install and maintain, have high energy consumption, and are poor in economy, so they cannot be applied to low-cost life in rural areas. Therefore, there is an urgent need to develop an economical rural domestic sewage treatment equ...
