Tank-type septic tank for rural sanitary toilet

Abstract

The invention discloses a tank type septic tank for a rural sanitary toilet. The septic tank comprises a horizontal cylindrical tank body, wherein two ends of the upper part of the tank body are provided with an excrement inlet and an outflow port respectively; the excrement inlet is vertically and upwardly formed along the radial direction of the tank body and connected with a toilet stool through an excrement inlet pipe; and the outflow port is horizontally formed along the axial direction of the tank body and used for allowing excrement to flow out or is connected with a next-stage septic tank through a communicating pipe. The excrement inlet is vertically and upwardly formed instead of laterally formed, so the problem of serious leakage at the joint of the tank body and a pipeline is avoided, and the vertical soil pressure borne by the pipeline is greatly eliminated; meanwhile, a lower bend can be prevented from being formed at the joint of pipelines, and therefore, the pipelines are prevented from being blocked by deposited excrement. Annular ribs are arranged on the tank body, so the pressure resistance and the ring stiffness of the septic tank are improved; the tank body ismanufactured by adopting a rotational molding integral forming process, is formed in a non-pressure manner, has good edge strength, high compressive strength, acid and alkali resistance and corrosionresistance, can be deeply buried, and is applicable to septic tanks for rural toilet improvement in northwest cold and dry regions with collapsible loess geology.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment and relates to a septic tank, in particular to a tank-type septic tank suitable for rural toilet reform plans. Background technique [0002] With the rapid growth of economic construction, the living conditions in rural areas are improving day by day. Most of the traditional rural toilets are open-air pit toilets, which are dirty, smelly, have many mosquitoes, and are easy to spread diseases; they cannot be washed, especially when it rains, they are easily covered by rainwater The groundwater is polluted by rushing into the ditch water pool, seriously affecting environmental sanitation, and there are great unsafe factors. According to statistics, 80% of infectious diseases in rural areas of my country are caused by toilet feces pollution and unsanitary drinking water, among which there are more than 30 infectious diseases related to feces. Extensive implementation of rural toile...
