Rural domestic sewage treatment system based on small watershed form

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a rural domestic sewage treatment system based on a small watershed morphology, the rural domestic sewage treatment system comprises a temporary storage tank, a filter tank, a treatment tank, a movable residue filtering assembly and a pushing assembly, the temporary storage tank, the filter tank and the treatment tank are connected through a pipeline, and the movable residue filtering assembly is arranged in the filter tank and comprises a filtering assembly and a rotating assembly; the filtering assembly is used for filtering solid impurities in sewage, the filtering assembly comprises an inner filter part and an outer filter part, the filtering assembly composed of the inner filter part and the outer filter part can effectively collect the solid impurities in the sewage, and after the inner filter part is full of the solid impurities, the filtering assembly can be rotated by utilizing the rotating assembly consisting of a motor, a fixed block, a bearing and the like, so that the opening of the filtering assembly faces upwards, and then the fastening screw between the inner filter cone and the outer filter cone is dismounted, so that the inner filter cone can be lifted out for removing solid impurities, and filtered garbage is relatively convenient to remove.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a rural domestic sewage treatment system based on the form of a small watershed. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.) ), the organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens multiply with the organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. Among them, rural domestic sewage treatment is to remove and degrade harmful substances and environmental pollution components in...

Problems solved by technology

[0004] The purpose of the present invention is to provide a rural domestic sewage treatment system based on the form of a small watershed to solve the problem that no flexible water solid impurity collection structure is provided in the above-mentioned background technology, and it is inconvenient to collect and remove solid impurities. In addition, Traditional rural domestic sewage treatment is not convenient for quick cleaning of floating garbage in sewage, which may easily cause the problem of floating garbage
