Domestic sewage purification treatment equipment with liquid suction function and use method

Abstract

The invention relates to the technical field of domestic sewage purification treatment, in particular to domestic sewage purification treatment equipment with a liquid suction function and a use method. A liquid suction assembly based on a piston is adopted so that the device can realize automatic liquid suction; a filter screen is used for filtering larger impurities in the sewage, the subsequentpurification burden is reduced, and the larger impurities are blocked on the left side of the filter screen and lifted into a slag receiving cavity so that the larger impurities are convenient to collect and are subsequently discharged from a slag discharge pipe; a conversion assembly is adopted so that a driving assembly enables a fourth rotating shaft to rotate forwards and backwards through the conversion assembly; in this way, a stirring assembly arranged at the bottom end of the fourth rotating shaft rotates along with the fourth rotating shaft, sewage and chemicals flowing into a preparation box are stirred and mixed through transverse stirring rods and vertical stirring rods, and purification treatment is conducted; the stirring rod periodically rotates forwards and backwards so that the turbulence intensity is effectively improved, and the medicament treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage purification treatment, in particular to a domestic sewage purification treatment equipment with a liquid absorption function and a use method. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. [0003] 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 infectious viruses, etc.). The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the...

Problems solved by technology

[0005] 1. Pathogen contamination;

[0006] 2. Aerobic organic pollution;

[0007] 3. Eutrophication pollution;

[0008] 4. Bad smell, manifested as: ① hindering normal respiratory function and reducing digestive function; mental irritability, reduced work efficiency, reduced judgment and memory; working and living in a foul smelling environment for a long time will cause olfactory disturbance and damage the central nervous system and brain The excitatory and regulating functions of the cortex; ② some aquatic products are contaminated with stench and cannot be eaten or sold; ③ foul-smelling water bodies cannot be used for swimming, fish farming and drinking, which destroys the use and value of water; ④ can also produce hydrogen sulfide and formaldehyde other toxic hazards

[0010] 6. Increased groundwater hardness;

[0011] 7. Toxic substance pollution

[0013] First of all, the existing devices either manually add liquid or use pumps to absorb liquid. The former is obviously cumbersome to operate, while the latter’s pump and subsequent stirring components adopt an independent design. The inventor has considered structural design so that The two are driven by a single motor to realize the method of liquid absorption and stirring, but later found that the subsequent addition of sewage will have a certain impact on the overall treatment effect, and special design and control of liquid absorption are still indispensable; secondly , there are many large particles of impurities in domestic sewage, which will affect the amount of chemical reagents and need to be treated; at the same time, there is room for improvement in the mixing effect of chemical reagents and sewage
