Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and in particular relates to integrated sewage treatment equipment. Background Art

[0002] Wastewater treatment: The process of purifying sewage to ensure that it meets the water quality requirements for discharge into a certain water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. The topic of water pollution is constantly being raised, especially the problem of groundwater pollution. With the awakening of people's environmental awareness, the concern for water pollution has reached an unprecedented level. According to the source of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage, and medical sewage, etc., while domestic sewage is sewage generated in daily life. It refers to a complex mixture of various forms of inorganic and organic matter. With the development of science and technology, the direct utilization of sewage has become possible. The sewage source heat pump system is used to utilize urban raw sewage. The so-called raw sewage is the untreated domestic and industrial wastewater directly discharged by the city. The current utilization method is to directly enter the sewage source heat pump system for heat exchange, which provides indoor cooling and heating for urban buildings while consuming a small amount of electricity. Wastewater reuse presents several technical challenges that must be overcome: clogging, corrosion, and heat exchange efficiency. A sewage-source heat pump system consists of two components: a sewage heat exchanger and a sewage-source heat pump. Urban sewage enters the sewage heat exchanger directly for heat exchange, and the heat is then transferred to the interior of the facility by the heat pump.

[0003] Village and town sewage primarily consists of domestic sewage and agricultural wastewater. Domestic sewage has a relatively fixed composition, primarily containing organic matter such as carbohydrates, proteins, amino acids, and fats, making it more suitable for bacterial growth and a breeding ground for bacteria and viruses. However, domestic sewage is generally non-toxic and has a certain fertilizer effect, allowing it to be used to irrigate farmland. Agricultural wastewater, on the other hand, has a diverse composition, requiring different treatment methods depending on the season, location, and development goals of villages and towns. To reduce wastewater discharge and its complexity, treatment should be combined with the nationally promoted biogas digester construction to separate toilet flushing water (black water) from other domestic water (grey water). Grey water is treated by a natural purification system, and black water and human and animal feces are treated in anaerobic digesters. This not only reduces the amount of sewage discharged, the complexity and treatment costs, but also has important significance for the development of clean and new energy in rural areas, the protection of the human living environment, and the promotion of sustainable development of the rural economy and society. The role of the sewage treatment station is to treat industrial and domestic sewage to meet the prescribed emission standards. It is an important facility for protecting the environment. Sewage treatment stations are already very common in industrially developed countries, while there are very few sewage treatment stations in villages and towns in my country, but they will gradually increase in the future. In order for these sewage treatment stations to truly play a role, they also need to rely on strict emission systems, organization and management systems to ensure it.

[0004] At present, in the process of sewage treatment, most of the time, integrated filtering equipment is used to filter and purify the sewage before discharging it. However, in actual use, the impurities in the sewage accumulate over a long period of time, which can easily cause blockage of the filter plates and grilles, and are inconvenient to clean. At the same time, the large amount of dirt accumulated in the sedimentation tank can easily cause blockage of the pipeline by direct discharge, resulting in high maintenance costs and affecting the normal ecological treatment of sewage. Therefore, it is necessary to study an integrated sewage treatment equipment to solve the above problems. Summary of the Invention

The motor 82 works to drive the driven gear 10 to rotate through the driving gear 81, and the driving gear 81 drives the hollow plate 13 to rotate forward through the gear ring 7, and the driven gear 10 drives the grinding rod 12 to rotate in the opposite direction, so that the grinding rod 12 and the hollow plate 13 rotate in opposite directions to achieve the grinding of impurities. When the impurities are ground to a certain size, they can pass through the hollow plate 13 into the box body 1.

After the liquid medicine is added through the liquid inlet pipe 17, the sewage is mixed.
