Medical sewage pretreatment device

Technical Field

The utility model relates to a sewage treatment technical field especially relates to a medical sewage pretreatment device.

Background

Sewage treatment is a process of purifying sewage to meet the requirement of draining a certain water body or reusing the water body. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people. The sewage treatment is generally classified into production sewage treatment and domestic sewage treatment according to the classification of sewage sources. The production sewage comprises industrial sewage, agricultural sewage, medical sewage and the like, and the domestic sewage is sewage generated in daily life and refers to complex mixtures of various forms of inorganic matters and organic matters. The pollution property of medical sewage is similar to that of domestic sewage, the main pollutants are three types, the first type is suspended matter SS, the second type is organic pollutants CODcr and BOD5, the third type is inorganic nutrient salt N and P, if the medical sewage is not purified and directly discharged, the environment is greatly polluted, before the medical sewage is treated, sewage pretreatment is required, the sewage pretreatment is a pretreatment facility which is set according to the requirements of subsequent treatment processes on water quality before the sewage enters the traditional sedimentation, biological treatment and the like, and the throat of a sewage treatment plant is provided;

however, most of the existing medical sewage pretreatment devices perform mixed precipitation of sewage and medicaments through simple stirring blades, and under the rotation of the stirring blades, water flow is stressed to rotate, so that the sewage and the medicaments rotate together, and parts of the sewage and the medicaments are relatively static, so that the precipitation time is prolonged, the fusion efficiency is low, and the effect is poor.

The prior patent (publication number: CN 215946985U) discloses a medical sewage pretreatment device, which can be used for driving a stirring shaft to perform eccentric stirring along the front, back, left and right tracks through the gear in a way that two fixed blocks are symmetrically arranged on the upper side in a settling tank, two gears are symmetrically arranged on the upper side in the settling tank, and a plurality of stirring blades are arranged on the circumferential outer wall of the stirring shaft at equal intervals in an annular way and are tightly matched with each other between structures, so that the device drives the stirring shaft to perform eccentric stirring along the front, back and left tracks through the gear, and simultaneously drives the stirring shaft to rotate through the rotation of the gears, thereby driving the stirring blades to stir sewage, and further leading the stress direction of liquid to be pushed by a reaction force at any time, thereby improving the efficiency of fusing sewage and a medicament, ensuring the effect of sedimentation, and laying a foundation for further treatment in the later period; the upper end of the left side of the settling tank is provided with the liquid level sensor, and the liquid level sensor is designed, so that a worker can master the internal liquid level change at any time; the stirring leaf is fan-shaped structure setting, and a plurality of stirring leaves are different angle settings, make it can further improve the efficiency that the stirring fuses.

However, the above-designed medical sewage pretreatment device has some disadvantages in practical application: the medical sewage pretreatment device designed as above is completely unnecessary due to the fact that a special stirring structure is deliberately arranged, drugs assisting in precipitation of suspended matters in sewage are dissolved in sewage all the time, a common stirring structure can completely accelerate melting of liquid medicine, the medical sewage pretreatment device designed as above is not provided with a sundries intercepting structure, medical appliances such as gauze or cotton yarn can float on the surface of the medical sewage pretreatment device due to the fact that suspended silt and dust are contained in the sewage, and therefore if the medical appliances such as gauze or cotton yarn cannot be intercepted, the problem that the cotton yarn blocks a water outlet in the sewage discharging process is likely to happen.
