Problems solved by technology

The above technologies can achieve good treatment effects in the treatment of rural domestic sewage; however, they often have the disadvantages of large footprint and low treatment efficiency, and the treated effluent cannot meet the reuse standard
However, when the traditional activated sludge method and biofilm method are used to treat rural domestic sewage, the infrastructure and operating costs are higher than those of artificial wetlands, stabilization ponds, land infiltration, etc., and the effluent after treatment cannot meet the reuse standards.

Abstract

The invention provides a rural domestic sewage treatment system. The rural domestic sewage treatment system comprises a reaction tank, a water-feeding driving type biological rotating disc, an absorbing and filtering device and an ultraviolet sterilization device, wherein the water-feeding driving type biological rotating disc comprises a plurality of disc pieces; each disc piece comprises a framework and a biological film carrier covering on the framework; a plurality of water feeding grooves are formed in the periphery of the disc piece and are containers with opened top surfaces; the water-feeding driving type biological rotating disc is erected above the reaction tank by a rotary shaft, and the lower part of the disc piece is positioned in the reaction tank all the time; a water feeding pipeline connected with a sewage source is provided with a plurality of water feeding pipes; pipe openings of the plurality of water feeding pipes are respectively formed in the positions in the water feeding grooves through which water can be injected into one disc piece; a water outlet of the reaction tank is connected with a water discharging pipe by an absorbing and filtering device; the ultraviolet sterilization device is arranged on the water discharging pipe. The rural domestic sewage treatment system provided by the invention has the advantages that the water-feeding driving type biological rotating disc realizes rotation by means of water feeding, so that the use of local materials is achieved and the cost is low; the effect of treating the rural domestic sewage is good and the quality of the discharged water can meet the recycling standard completely.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a rural domestic sewage treatment system. Background technique [0002] With the continuous improvement of farmers' living standards, the domestic water consumption of residents in rural areas is increasing day by day, and the amount of sewage discharge is also increasing. If it is not effectively treated, it will seriously deteriorate the rural water environment and affect the quality of life of rural residents. At present, the commonly used rural domestic sewage treatment technologies mainly include: anaerobic digesters, constructed wetlands, stabilization ponds and land infiltration systems. Among them, the anaerobic biogas digester treats rural domestic sewage, and the effluent water quality can meet the discharge standard, and can produce fertilizer suitable for agricultural production. The stabilization pond is to make the sewage slowly flow and store in the natur...
