Problems solved by technology

Due to factors such as insufficient urban pipe network construction, some domestic sewage is discharged into rivers and other places after simple treatment in septic tanks, carrying a large number of germs and nutrients such as nitrogen and phosphorus, and seriously polluting surface water
At present, urban sewage treatment plants are relatively complete, but there are also unfavorable factors such as high infrastructure costs, large floor area, and long treatment process.
Lack of a set of simple and miniaturized sewage treatment methods suitable for city squares, stations, tourist attractions, etc.

Embodiment Construction

[0010] like figure 1 and figure 2 As shown, using this sewage treatment method, the process flow of the treatment device is that the sewage first enters the anaerobic pool (7) for decomposition, then enters the aerobic pool (8) to continue to decompose organic matter, and the air pump (13) continuously flows into the aerobic pool (8) Fresh air is blown in, and the sewage enters the sedimentation tank (9) for sedimentation, filtration and separation. The supernatant liquid enters the water storage tank (11), and the water in the tank is sterilized by an ultraviolet sterilizer (10) to kill bacteria. The treated water can be discharged by the pressure-stabilized flushing pump (12) for circulating toilet flushing. After a period of use, turn on the sewage pump (15) to discharge part of the sludge at the bottom of the cabinet to improve the treatment efficiency. The control of the equipment is all concentrated on the electric control box (14), which can realize automatic control...

Abstract

The invention relates to a novel domestic sewage treatment method. The treatment method mainly aims at excrement sewage of a toilet. The mode combining activated sludge biodegradation, inclined tube sedimentation and physical disinfection and sterilization is used. The method mainly comprises the four steps of anaerobic treatment, aerobic treatment, sedimentation treatment and disinfection treatment in sequence. The method can effectively remove nutrient substances such as nitrogen and phosphorus in domestic sewage and remove bacterial viruses such as escherichia coli, and is clean, sanitary,free of peculiar smell and capable of efficiently treating sewage. The quality of the treated water can reach the secondary emission standard of municipal sewage treatment plant pollutant emission standards. The treated water can be used for toilet flushing; in addition, reclaimed water can be recycled, circulating water flushing can be achieved, and water resources are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment. Background technique [0002] In the 21st century, the rapid development of the human economy has also caused serious damage and pollution to the environment, which has seriously threatened people's health. Among them, the degree of water pollution has caused a serious imbalance, and nature has lost its original self-purification cycle ability due to excessive pollution. Water is closely related to people's life. During the metabolism process of the human body, along with drinking water and food, various elements in the water enter the various parts of the human body through the digestive tract. When the water contains bacteria, viruses, heavy metals and other harmful substances, the harm to the human body is very serious. It is imminent to restore the ecological balance of nature through sewage treatment projects. At present, urban sewage mainly includes domestic sewage and ...
