Unpowered purification tank

Abstract

The invention relates to an unpowered purification tank which comprises a tank body, a flow inlet, a flow outlet, an inspection port and a cover overlaid on the inspection port, wherein the tank body is divided into a first anaerobic tank and a second anaerobic tank through a partition plate in the middle space of the tank body; the bottom of each anaerobic tank is provided with a grate shelf for carrying a filtering material; the flow inlet is positioned above the first anaerobic tank; the flow outlet is positioned above the second anaerobic tank; and the highest point of the flow outlet is below the horizontal line of the lowest point of the flow inlet. The invention has the following advantages: 1) domestic sewage discharged from toilets, kitchens, bathrooms, lavatories, washing machines and the like can be purified without power; 2) a filtering tank has an automatic cleaning function, and foreign bodies blocking the filtering material can be cleaned away without any power; 3) through the anaerobic tanks and the filtering tank, 50-80% of BOD (biochemical oxygen demand) and 50-80% of floating substances in the domestic sewage can be removed; and 4) through a sterilizing tank, coliform bacteria in the domestic sewage can be killed, thereby achieving up-to-standard discharge.

Description

Technical field: [0001] The invention relates to a kind of water, waste water and sewage treatment, more specifically to a kind of unpowered purification tank. The septic tank is used to purify the feces and urine discharged from the toilet, as well as the sewage discharged from the kitchen, bathroom, toilet, washing machine, etc., and does not need power, power supply, air supply and other devices. Background technique: [0002] In the past, excrement and urine discharged from toilets, as well as waste water discharged from kitchens, bathrooms, toilets, washing machines, etc., were directly discharged into septic tanks for storage without purification. Septic tanks only store these domestic sewage, and after a period of time, these unpurified domestic sewage are directly discharged into rivers, ponds, lakes, and oceans, which is the direct cause of environmental pollution. These domestic sewage contain a large number of harmful microorganisms such as pathogenic coliform ba...

AI Technical Summary

Problems solved by technology

These domestic sewage contain a large number of harmful microorganisms such as pathogenic coliform bacteria that endanger humans and the environment. If these harmful microorganisms cannot be eliminated in septic tanks, these harmful microorganisms will flow into rivers, ponds, lakes, and oceans, which will harm the environment and human beings. Second, these domestic sewage will cause partial or complete decay in the septic tank, resulting in a foul smell in the surrounding air

Another point to be pointed out is that most of these septic tanks are made of glass fiber reinforced plastic and cement, which require skilled personnel to manufacture and cannot be mass-produced

Even if it is manufactured by skilled technicians, it will encounter defects with some small holes or small cracks, which are the cause of water leakage in septic tanks.
