Combined septic tank

Abstract

The invention provides a combined septic tank. The septic tank is characterized by comprising a hollow cylinder connected by pieces with flange on the periphery, and end blocks which are provided with flange on the periphery and are connected on the end part of the hollow cylinder, wherein the pieces or / and the end blocks are provided with an inlet and an outlet. Series of the pieces and the corresponding end blocks with flange on the periphery in different arc lengths and different lengths can be produced according to requirement so as to conveniently assemble the cistern with required diameter and length according to requirement, thereby meeting the requirements of users on different products. The pieces and the end blocks can be piled, so the pieces and the end blocks occupy neither production space or storage space after production, nor transportation space to greatly reduce investment on workshops and warehouses and transportation cost; the sealability of the septic tank is effectively increased and the strength of the septic tank is enough, which can be made of corrosion-resistant waste plastics, saves resources, has low cost, and is worthy of popularization and application.

Description

technical field [0001] The invention relates to a septic tank, in particular to a combined septic tank, which belongs to the technical field of building supporting facilities. Background technique [0002] As one of the building supporting facilities, the septic tank is to use the principle of sedimentation and anaerobic fermentation to collect and treat the feces discharged from the sewer of the building. It decomposes the solid matter in the feces through anaerobic fermentation. And let it sink to the bottom, and then it can be removed regularly, and the settled clear water flows out from the upper outlet of the septic tank, and is used as green water to irrigate plants, which greatly reduces the pollution caused by feces to rivers, lakes and rivers. Therefore, septic tanks can be used not only in cities, but also in vast rural areas, which is conducive to protecting the environment. Most of the existing septic tanks are built with stones and bricks, which is not only tim...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a combined septic tank to fundamentally solve the problems caused by the existing integrated septic tank, such as production, storage and transportation, which occupy a large area, require large investment, high transportation cost, small transportation capacity and low volume. Single, unable to change the volume according to the requirements of the site, etc.
