Water purification system applied to rural sewage treatment

Abstract

The invention belongs to the technical field of sewage treatment. The invention relates to a water purification system applied to rural sewage treatment. The sewage treatment equipment comprises a sewage treatment equipment body, wherein a water inlet pipe is fixedly mounted on one side of the sewage treatment equipment body; a water outlet pipe is fixedly installed on the side, away from the water inlet pipe, of the sewage treatment equipment body, a sewage tank is arranged on one side of the sewage treatment equipment body, a fixing cavity with an opening in one side is formed in the sewagetank, a filter cartridge is arranged in the fixing cavity, a fixing groove is formed in the inner wall of the top of the fixing cavity, and a first threaded hole is formed in the inner wall of the topof the fixing groove. The water purification system is simple in structure and is economical and practical, wherein large-particle impurities and solid garbage in sewage can be filtered, so that thesituation that the large-particle impurities and the solid garbage enter the sewage treatment equipment body, and consequently normal use and work of the sewage treatment equipment body are affected is avoided; in addition, the filter cartridge can be cleaned, disassembled and assembled conveniently, operation is convenient, and the sewage purification quality and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water body purification system applied to rural sewage treatment. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as Parasite eggs and intestinal infection virus, etc.), the organic matter in domestic sewage is extremely unstable, easy to rot and produce stench, bacteria and pathogens multiply by using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases, however , my country produces a lot of domestic sewage every year, and most villages do not have drainage channels and sewage treatment systems, resulting in the random discha...

[0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as Parasite eggs and intestinal infection virus, etc.), the organic matter in domestic sewage is extremely unstable, easy to rot and produce stench, bacteria and pathogens multiply by using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases, however , my country produces a lot of domestic sewage every year, and most villages do not have drainage channels and sewage treatment systems, resulting in the random discharge of domestic sewage, seriously polluting the ecological environment in rural areas, and directly threatening the health of farmers and the economic development of rural areas

[0003] After retrieval, the authorized public number is CN205974174U, which discloses a modular four-pool purification system for rural domestic sewage treatment, including successively connected settling tanks, anaerobic tanks, intermediate pools, and humic filler wetland units. The unit includes crushed stone layer, humus filler filter material layer, and quartz sand layer from bottom to top. There is a wetland plant layer on the quartz sand layer. Combining the two technologies of fermentation and humic filler wetland, the layout is more reasonable, and it realizes non-powered operation, which improves the self-purification ability of the water body and improves the reuse of water resources. However, the water inlet pipe end of the sewage treatment equipment is not installed. There is a filter device, because there are many large particles of impurities and solid waste in domestic sewage, these large particles of impurities and solid waste directly enter the sewage treatment equipment, which will easily lead to blockage of its internal pipelines, etc., affecting the normal use and work of the equipment, thus Affect the quality and efficiency of sewage purification. Therefore, we propose a water purification system applied to rural sewage treatment to solve the above problems
