Description

Micro-polluting water purification equipment Technical Field

[0001] This utility model relates to the field of water treatment technology, and mainly to a device for purifying slightly polluted water. Background Technology

[0002] With industrial and urban development, people are discharging more and more pollutants into water bodies during production and daily life. Simultaneously, due to continuous improvements in analytical technology, the types of trace pollutants detectable in water bodies are also constantly increasing. These substances, despite their low concentrations, are persistent, bioaccumulative, and can accumulate through the food chain, reaching levels harmful to humans and other organisms, thus severely impacting the reproductive, nervous, and immune systems. Therefore, micropollutants in water bodies are increasingly attracting attention.

[0003] In existing technologies, the treatment of slightly polluted water requires multiple processes, which necessitates the use of various different equipment. This results in low space utilization and poor treatment efficiency, with a slow decomposition rate of pollutants and toxic substances in the slightly polluted water source, thus affecting the treatment efficiency to some extent.

One end of the main body 1 is equipped with an inlet pipe 2, and the other end is equipped with an outlet pipe 3. The main body 1 has three partitions 4 inside, which divide the main body 1 into four reaction tanks. From left to right, the reaction tanks include an interconnected first reaction tank 5, a second reaction tank 6, a third reaction tank 7, and a fourth reaction tank 8. The volume of the third reaction tank 7 is twice that of the first reaction tank 5, the second reaction tank 6, and the fourth reaction tank 8. The first reaction tank 5 is equipped with a vertical filter screen 9. The second reaction tank 6 is equipped with a vertical activated carbon plate 10. The lower part of the third reaction tank 7 is equipped with a horizontal aeration component. The fourth reaction tank 8 is equipped with a stirring component, and a dosing pipe 11 is located near the top of the fourth reaction tank 8. Among them, the filter screen plate 9 in the first reaction tank 5 and the activated carbon plate 10 in the second reaction tank 6 are pre-filters for adsorbing large and small particles; the aeration component in the third reaction tank 7 is connected to an external air pump to increase oxygen in the third reaction tank 7; the dosing pipe 11 in the fourth reaction tank 8 can add water purification agents, and under the action of the stirring component, the micro-sewage and water purification agents are fully stirred and mixed to disinfect the chemical substances in the micro-sewage.

[0030] Based on the above technical means: the micro-polluting water purification equipment adopts an integrated structure, dividing the inner cavity of the main body 1 to form different reaction tanks. Different reaction tanks have different water purification effects. The equipment has a small footprint, high space utilization, and good sewage treatment effect.

[0031] Specifically, the aeration assembly includes a pipe 12 arranged at the bottom of the third reaction tank 7 and multiple aeration heads 13 connected to the pipe 12. The aeration heads 13 are evenly arranged on the pipe 12. The pipe 12 is connected to an external air pump and supplies oxygen to the third reaction tank 7 through the pipe 12 and the aeration heads 13.

[0032] Specifically, the stirring assembly includes a motor 14, a connecting rod 15, and three stirring paddles 16 fixed to the top of the fourth reaction tank 8. The connecting rod 15 is connected to the output shaft of the motor 14, passes through the top of the fourth reaction tank 8, and extends into the interior of the fourth reaction tank 8. The stirring paddles 16 are fixed to the connecting rod 15.

[0033] Specifically, each of the partitions 4 between the first reaction tank 5 and the second reaction tank 6, the second reaction tank 6 and the third reaction tank 7, and the third reaction tank 7 and the fourth reaction tank 8 is provided with a connecting pipe 17; a detachable interceptor 18 is provided on the connecting pipe 17, which serves to intercept and prevent large particulate impurities from entering the next stage reaction tank from the previous stage reaction tank through the connecting pipe 17.

[0034] Specifically, the outer wall of the connecting pipe 17 is provided with an external thread 19, and the inner wall of the interceptor 18 is provided with an internal thread 20 that matches the external thread 19. That is, the interceptor 18 is detachably connected to the connecting pipe 17 by means of a threaded connection.

[0035] Specifically, the top of the first reaction pool 5, the second reaction pool 6 and the third reaction pool 7 are all equipped with manhole covers 21, through which personnel can observe the internal conditions of the first reaction pool 5, the second reaction pool 6 and the third reaction pool 7.

[0036] This utility model relates to a water purification device for slightly polluted water, and its working principle is explained in conjunction with the accompanying drawings:

[0037] The inlet pipe 2 and outlet pipe 3 are connected to the external pipe 12 respectively. The micro-sewage is transported from the inlet pipe 2 into the first reaction tank 5 of the main body 1 through the external pipe 12. After being filtered by the filter screen plate 9, it flows into the second reaction tank 6 through the connecting pipe 17. After being adsorbed by the activated carbon plate 10, it flows into the third reaction tank 7 through the connecting pipe 17. The external air pump works to supply nutrients and aerate the third reaction tank 7 through the pipe 12 and the aeration head 13. It then flows into the fourth reaction tank 8 through the connecting pipe 17. Water purification agent is added into the fourth reaction tank 8 through the dosing pipe 11. The motor 14 is started. The motor 14 drives the connecting rod 15 to rotate, which in turn drives the stirring paddle 16 to stir the micro-sewage in the fourth reaction tank 8, fully mixing and blending the micro-sewage and water purification agent. Finally, the purified micro-sewage flows out from the outlet pipe.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
