Example Embodiment

[0022] The invention provides an integrated domestic sewage treatment equipment suitable for rural sewage treatment. The main process adopts the ICEAS process. The equipment has simple process flow, low land occupation, low cost and operation management cost, flexible operation mode, and satisfactory effluent quality In 2005, Beijing Municipality promulgated the "Water Pollutant Discharge Standard" (DB11 / 307-2005) in the Class I and B standard.

[0023] The purpose of the present invention is achieved through the following technical solutions: the village domestic sewage is discharged into the sewage treatment station, first passes through the grille, intercepts and removes the larger-diameter suspended matter and floating matter in the sewage, and protects the lift pump and the aerator effect. The sewage treated by the grille flows into the sewage lifting well, which is not only used to install the sewage pump, but also has a certain function of adjusting the amount of sewage. Af...

Abstract

The invention relates to an integrated domestic sewage treatment device, which is suitable for integrated treatment of rural (villages and towns) domestic sewage far away from municipal drainage pipelines, and is characterized by comprising a biochemical reaction tank, wherein the biochemical reaction tank is divided into a main reaction zone and a pre-reaction zone by a division plate, the main reaction zone is communicated with the pre-reaction zone through a bottom connecting port of the division plate, the pre-reaction zone is communicated with a biological selection zone, the biological selection zone is connected with a winding shaft through a pipeline and a lifting pump, and a grizzly screen is arranged between the winding shaft and a domestic sewage inlet; a jet aeration machine, a sludge reflux pump and a decanter are arranged in the main reaction zone; and the decanter is connected with a water outlet pipe, and a sludge outlet of the sludge reflux pump is connected with a sludge tank, the biological selection zone and the pre-reaction zone respectively.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to integrated domestic sewage treatment equipment, which is suitable for the integrated treatment of rural (township) domestic sewage far away from municipal drainage pipes. Background technique [0002] With the increase of domestic sewage discharge in rural areas (towns and towns), the intensification of non-point source pollution, coupled with the lack of suitable treatment technologies and the lagging water treatment facilities, the difficulty of environmental pollution control in rural areas (towns and towns) is more prominent than that in cities, and it has become a new rural construction in my country. main obstacle. In order to make the majority of farmers step into a well-off society in an all-round way, the party and the state attach great importance to the environmental protection and construction of the new socialist countryside. There must be a reasonable treatment metho...
