Embodiment Construction

[0015] The present invention will be described in further detail below by means of specific embodiments:

[0016] The reference signs in the drawings of the description include: medicine box 10, discharge port 101, driven wheel 21, discharge port 211, driving wheel 22, second connecting shaft 23, first connecting shaft 24, wind wheel 25, sewage pipe 30, air intake pipe 40, feed pipe 50.

[0017] Such as figure 1 As shown, a sewage treatment dosing device, from right to left is a sewage pipe 30, an air inlet pipe 40, a discharge assembly and a medicine box 10. The air intake pipe 40 is in the shape of 7, and the lower end of the air intake pipe 40 communicates with the sewage pipe 30, and the upper end extends to the outside to communicate with the outside world. The discharge assembly includes a wind wheel 25 , a first transmission shaft, a driving wheel 22 and a driven wheel 21 . A rotating bearing is installed in the intake pipe 40 , and the first transmission shaft is ro...

Abstract

The invention belongs to the field of sewage treatment, and particularly discloses a chemical adding device for sewage treatment. The chemical adding device comprises a chemical box, wherein the bottom of the medicine box is provided with a discharge hole. The chemical adding device also comprises a sewage pipe, an air inlet pipe and a discharging component, wherein one end of the air inlet pipe is communicated with the sewage pipe, and the other end of the air inlet pipe is communicated with outside; the discharging component comprises a wind wheel, a first transmission shaft, a driving wheel and a driven wheel meshed with the driving wheel; the wind wheel and the driving wheel are coaxially connected through the first transmission shaft; the wind wheel is rotatably arranged in the air inlet pipe; the driven wheel is rotatably arranged on the bottom of the medicine box; the driven wheel is provided with a blowdown hole, and the blowdown hole is periodically communicated with the discharge hole when the driven wheel rotates. Compared with the traditional chemical adding device, the scheme has the advantages of simple structure and low construction cost. Meanwhile, according to the scheme, flowing of sewage per se is utilized to generate negative pressure so as to realize the automatic chemical adding of the chemical adding device, other power mechanisms are not required, energy consumption is effectively reduced, and energy is saved.

Description

technical field [0001] The invention belongs to the field of sewage treatment. Background technique [0002] Sewage treatment is a variety of economical, reasonable, scientific and effective processes for urban domestic sewage and industrial wastewater. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. [0003] Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment according to the degree of treatment. Primary treatment mainly removes suspended solid pollutants in sewage, and most physical treatment methods can only meet the requirements of primary treatment. After primary treatment, BOD can generally be removed by about 30%, which does not meet the discharge standard. Primary treatment belongs to the pretreatment of secondary treatment. The secondary treatment mainly removes colloi...
