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.

Embodiment Construction
[0022] The specific implementation will be described in detail below in conjunction with the accompanying drawings:
[0023] Figure 1a ~ Figure 1bIt is a structural longitudinal section and a transverse section view of a purification tank according to an embodiment of the present invention. In the figure, a kind of unpowered purification tank includes: a tank body 1, an inflow port 18, an outflow port 19, an inspection port 11 and a cover covering the inspection port. The tank body 1 is divided into a bottom space, a middle space, and an upper space , the middle space divides the tank body 1 into the first anaerobic tank 21 and the second anaerobic tank 22 through the partition plate 12, and the bottoms of the first anaerobic tank and the second anaerobic tank are respectively provided with the first filter filter material 3a, the grid shelf 20 of the second filter material 3b, the described inflow port 18 of right angle is positioned at the top of the first anaerobic tank 2...

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...
