Large three-lattice integrated geographical septic tank

Abstract

The invention discloses a large three-lattice integrated geographical septic tank and a making method thereof. The large three-lattice integrated geographical septic tank comprises a tank body, a feces inlet pipe, a feces outlet pipe and a check hole, wherein the tank body comprises an upper half tank body and a lower half tank body which are abutted together, and a sealing rubber mat is arranged at a combined part of the upper half tank body and the lower half tank body; the tank body is internally provided with a two-lattice support shaped like a Chinese character 'Jing' and a partition plate, wherein the support shaped like the Chinese character 'Jing' and the partition plate are used for sequentially dividing the inside of the tank body into three cabins which are respectively a first-stage anaerobic chamber, a second-stage anaerobic chamber and a clarifying chamber; the bottom of the first-stage anaerobic chamber is communicated with the bottom of the second-stage anaerobic chamber; the partition plate is provided with holes which are vertically staggered. The large three-lattice integrated geographical septic tank can be used for remarkably improving the compressive strength and has the characteristics of acid and alkaline resistance, corrosion resistance, long service life, no gaps, good integrality, no leakage, no pollution to underground water, no environment pollution, benefit for ecological environment and the like. By using the large three-lattice integrated geographical septic tank, the processes for treating sludge, digestion gas and wastewater at the water outlet end of the septic tank can be separated, so that the interference of an air floating phenomenon to wastewater treatment is avoided.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and relates to a septic tank, in particular to a large three-grid buried integral septic tank. Background technique [0002] The application of traditional septic tanks has a history of more than 100 years. It was originally used as a feces interception facility to avoid pipeline blockage. It plays an active role in intercepting and settling large particles in sewage, preventing pipeline blockage, and protecting the environment. . The technical principle is the contact mode of sewage and sludge. The deposited sludge is digested and degraded to produce digested gas such as methane, carbon dioxide, and hydrogen sulfide. Due to the flotation of digested gas, the sludge is disturbed, and the disturbing effect of digested gas on sludge can be Let the sludge and biological flora mix more fully, which is helpful for digestion and degradation. However, the sludge at the bottom rises with the d...

AI Technical Summary

Problems solved by technology

Because traditional septic tanks are built with masonry, cement and mortar, they have their own defects. According to incomplete statistics, more than 95% of sewage treatment tanks (septic tanks) begin to leak after 1-2 years of use. , seriously pollute the groundwater source; some septic tanks are easy to cause different degrees of inclination of the building due to the subsidence of the foundation

Traditional septic tanks have low technical content, poor corrosion function, simple manufacturing process, easy leakage, easy blockage, easy to freeze, and short cleaning cycle, which brings inconvenience to daily life and cannot meet the requirements of environmental protection and construction.
