Problems solved by technology

[0003] However, practice has proved that the existing brick or concrete septic tanks buried in the ground are easily corroded and peeled off by wet soil, water vapor, moisture immersion, acid, alkali and salt erosion, easy to infiltrate, poor durability, and the strength is reduced and easy to be damaged. ; not only affect the surrounding environment, but also not conducive to the protection of groundwater resources
[0004] And the extensive use of clay bricks causes a waste of clay resources, which does not comply with environmental protection policies
At the same time, the construction cost and construction period are also longer

Embodiment Construction

[0012] A preferred plastic septic tank, the septic tank is composed of the inner cavity of the housing 10 formed by connecting plastic plates 11, that is, the inner cavity of the housing 10 contains water and feces, and realizes anaerobic treatment of the feces. Housing 10 is provided with at least one opening for feeding and discharging. It is preferable to set the feeding port and the discharging port separately for ease of use. Larger manholes can also be provided to facilitate the cleaning of the septic tank inner cavity. The plastic plates 11 can be connected by a heat sealing process, or a flange-shaped connecting plate can be arranged on the edge of the plate body, and the plates can be screwed through the connecting plate. A sealing strip is arranged in the groove, and the sealing strip ensures that the inner cavity of the housing 10 after connection reaches the liquid-tight standard. Of course, a water-proof membrane may also be arranged in the inner cavity of the hous...

Abstract

The invention relates to a durable low-cost septic tank. The septic tank comprises a housing, the housing has a hollow inner cavity, the housing is provided with at least one opening communicated with the inner cavity, the housing is formed through the connection of a plurality of plastic plates, and surfaces of the plastic plates are uniformly provided with interlaced reinforcing ribs. The plastic housing of the invention substitutes bricks or concrete, a manner that the housing is formed through the connection of the plastic plates solves a problem that the injection molding processing of the whole housing is inconvenient, and the reinforcing ribs of the surfaces of the plastic plates solve a problem that the strength of the pure plastic material structure is low. So the plastic septic tank which has a firm structure is suitable for the industrial application, and the natural service life of the plastic septic tank which has good acid and alkali resistances is long after the plastic septic tank is buried underground. A container formed by the housing of the invention can be used as a water storage cellar and the like.

Description

technical field [0001] The invention relates to municipal engineering or sanitation facilities, in particular to a septic tank. Background technique [0002] Septic tank is a device for treating feces and filtering sediment. The principle is that the solidified matter decomposes at the bottom of the pool, and the hydrated objects on the upper layer enter the pipeline to flow away, preventing the pipeline from being blocked, and giving the solidified objects (feces and other garbage) enough time to hydrolyze. Existing septic tanks all are to be made of the pool body that forms by brickwork or concrete pouring and cover plate, and are buried in the ground. [0003] However, practice has proved that the existing brick or concrete septic tanks buried in the ground are easily corroded and peeled off by wet soil, water vapor, moisture immersion, acid, alkali and salt erosion, easy to infiltrate, poor durability, and the strength is reduced and easily damaged. ; Not only affect t...
