Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a pretreatment precipitation device for treating high-concentration complex wastewater. Background Art

[0002] The background art of the pretreatment precipitation device for treating high-concentration complex wastewater mainly involves the fields of environmental engineering and water treatment, especially for the treatment of industrial wastewater containing heavy metals and organic pollutants. Since the composition of this kind of wastewater is complex and the pollutant concentration is high, direct discharge will cause serious pollution to the environment. Traditional physical, chemical or biological treatment methods often fail to achieve ideal treatment effects. Therefore, developing a new type of pretreatment precipitation device, through physical precipitation combined with chemical flocculation, aims to effectively remove suspended solids and complexes in the wastewater, reduce the pollutant concentration, and improve the efficiency of subsequent treatment processes, which is of great significance for protecting the environment and water resources.

[0003] After retrieval, the text of the patent number "CN212640004U" mentions that "the utility model discloses a high-concentration wastewater treatment device, which relates to the field of wastewater treatment devices. Aiming at the problems of low flow rate and insecurity caused by the use of open fire in the existing high-concentration organic wastewater incineration device, the following scheme is proposed. It includes a mixing bin, a first cavity is opened in the mixing bin, and a convex nozzle is opened on one side of the mixing bin. One end of the convex nozzle away from the mixing bin is hermetically connected to a water inlet pipe, and the water inlet pipe communicates with the first cavity. A nozzle is installed at the water outlet of the water inlet pipe located in the first cavity, and one end of the water inlet pipe away from the mixing bin is hermetically connected to the water outlet of a booster pump. The water inlet of the booster pump is hermetically connected to a water inlet heat exchange pipe, and one end of the water inlet heat exchange pipe away from the booster pump is hermetically connected to a sewage pipe". When in use, the structure of the utility model is novel, and the device has a simple structure, is convenient to use, is not affected by open fire, water mist and water vapor, is safer and more reliable, and effectively improves the operation efficiency. However, when treating high-concentration complex wastewater, due to the presence of a large number of complex chemical materials in the wastewater, and most of these materials are soluble in water. If the chemical materials in the wastewater are not specifically overflowed, it is easy to cause environmental damage, and it is also difficult to separate the filtered water after treating the chemical materials in the water.

[0004] Therefore, we provide a pretreatment precipitation device for treating high-concentration complex wastewater to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pretreatment precipitation device for treating high-concentration complex wastewater to solve the problems raised in the above background art.

[0006] To achieve the above object, the present utility model provides the following technical solution: A pretreatment precipitation device for treating high-concentration complex wastewater, comprising a wastewater treatment tank and a wastewater treatment mechanism, wherein the wastewater treatment mechanism is installed inside the wastewater treatment tank;

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. With the setting of the wastewater treatment mechanism, when in use, the wastewater is pumped into the oil pollution treatment chamber through the feeding pump. After the pressure relief by the water distribution plate, the wastewater passes through the oil film separation plate to separate the grease carried in the water, thus avoiding the accumulation of grease and increasing the difficulty of subsequent wastewater treatment. The water distribution plate can effectively reduce the direct impact force of the water flow, thereby extending the service life of the oil film separation plate. The water level sensor will detect the current wastewater volume in real time. When the wastewater is discharged, the water level sensor will control the feeding pump to add wastewater again to avoid idling operation after the wastewater treatment is completed.

[0016] 2. With the setting of the wastewater treatment mechanism, the water flow flushes onto the pressure relief plate and then passes through the multi-stage filter screens to block and separate the flocs coagulated by the flocculant in the wastewater. The smaller and granular impurities such as gravel in the flocculant will be sent into the storage filter chamber by the next-stage multi-stage filter screen. In this way, when in use, the impurities can be separated in a segmented manner, which not only avoids the accumulation of materials and makes it impossible to continue using, but also enables faster multi-angle treatment of wastewater. At the same time, the rotating motor drives the groove rotating shaft to rotate in the groove shaft chamber. Since the unloading rack is buckled with the groove rotating shaft, when the groove rotating shaft rotates, the flocculant particles in the unloading rack will fall into the groove rotating shaft and then fall into the wastewater treatment tank with the rotation. In this way, when adding the flocculant, the amount can be better controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figures 1-4 As shown, the utility model provides a technical solution: a pretreatment precipitation device for treating high-concentration complex wastewater, comprising a wastewater treatment box 1 and a wastewater treatment mechanism 2, wherein the wastewater treatment mechanism 2 is installed inside the wastewater treatment box 1;

[0025] The wastewater treatment mechanism 2 includes an oil-water treatment component 21, a flocculant feeding component 22, a water level sensor 23 and a sedimentation component 24. The oil-water treatment component 21 is provided on the upper side of the wastewater treatment tank 1, and the flocculant feeding component 22 is provided on the right side of the oil-water treatment component 21. The water level sensor 23 is provided on the inner side of the wastewater treatment tank 1, and the sedimentation component 24 is provided on the right side of the water level sensor 23.

[0026] Furthermore, the oil-water treatment component 21 includes an oil treatment tank 211, a feed pump 212, a water separation plate 213 and an oil film separation plate 214. The oil treatment tank 211 is welded on the upper side of the wastewater treatment box 1, and the feed pump 212 is provided on the rear side of the oil treatment tank 211. The inner side of the oil treatment tank 211 is provided with a water separation plate 213, and the front side of the water separation plate 213 is provided with an oil film separation plate 214. When needed, the wastewater is poured into the oil treatment tank 211 through the feed pump 212. After the pressure is relieved by the water separation plate 213, the wastewater separates the oil and fat carried in the water through the oil film separation plate 214, thereby avoiding the accumulation of oil and fat, which makes subsequent wastewater treatment more difficult. The water separation plate 213 can effectively reduce the direct impact force of the water flow, thereby improving the service life of the oil film separation plate 214.

[0027] Further, the flocculant feeding component 22 includes a trough shaft bin 221, a grooved rotating shaft 222, a rotating motor 223, a discharging rack 224, and a storage bin 225. The trough shaft bin 221 is arranged on the right side of the oil-polluted water treatment bin 211. The grooved rotating shaft 222 is installed inside the trough shaft bin 221. The rotating motor 223 is installed on the front side of the grooved rotating shaft 222. The discharging rack 224 is installed on the upper side of the grooved rotating shaft 222. The storage bin 225 is welded to the upper side of the discharging rack 224. When in use, the rotating motor 223 drives the grooved rotating shaft 222 to rotate inside the trough shaft bin 221. At the same time, since the discharging rack 224 is buckled with the grooved rotating shaft 222, when the grooved rotating shaft 222 rotates, the flocculant particles in the discharging rack 224 will fall into the grooved rotating shaft 222 and then fall into the wastewater treatment tank 1 with the rotation. In this way, when adding the flocculant, the amount can be better controlled.

[0028] Further, the water level sensor 23 is welded to the wastewater treatment tank 1. The model of the water level sensor 23 is the DATA-51 series submersible water level sensor. When in use, the water level sensor 23 will detect the current wastewater volume in real time. When the wastewater is discharged, the water level sensor 23 will control the feeding pump 212 to add wastewater again to avoid idling operation after the wastewater treatment is completed.

[0029] Further, the precipitation component 24 includes a drain plate 241, a multi-stage filter screen 242, a filter storage bin 243, a water passing port 244, and an activated carbon filter 245. The drain plate 241 is arranged below the water level sensor 23. The multi-stage filter screens 242 are welded to the right side of the drain plate 241. The filter storage bin 243 is arranged below the drain plate 241. The water passing port 244 is arranged on the right side of the multi-stage filter screen 242. The activated carbon filter 245 is arranged below the water passing port 244. When in use, the water flow flushes onto the drain plate 241, and then the multi-stage filter screen 242 blocks and separates the flocs coagulated by the flocculant in the wastewater. The smaller and granular impurities such as gravel in the flocculant will be sent into the filter storage bin 243 by the next-stage multi-stage filter screen 242. In this way, when in use, the impurities can be separated in a segmented manner, which not only avoids material accumulation and makes it impossible to continue using, but also can perform multi-angle wastewater treatment faster.

[0030] Further, the activated carbon filter 245 is connected to the water passing port 244 by a card slot, and the activated carbon filter 245 is closely attached to the water passing port 244. After the wastewater treatment is completed, the activated carbon filter 245 can filter the impurities that have not been solidified by the flocculant in the water in the last step to improve the filtering intensity.

[0031] Embodiment 2

[0032] Please refer to Figure 1 and Figure 2As shown, as another embodiment of the present utility model in contrast to the first comparative example, a discharge assembly 3 is installed on the right side of the wastewater treatment tank 1. The discharge assembly 3 includes a water quality sensor 31 and a water pump 32. The water quality sensor 31 is welded to the right side of the wastewater treatment tank 1, and the water pump 32 is installed below the water quality sensor 31. When in use, the water quality sensor 31 senses the current water quality. When the water quality meets the standard, the water pump 32 pumps water to draw the qualified wastewater away.

[0033] Working principle: Move a pretreatment precipitation device for treating high-concentration complex wastewater to the working position. When in use, in the first step, first place the wastewater treatment tank 1 in the position where it is needed, then connect the wastewater discharge pipe to the feed pump 212, and then pump the wastewater into the oil pollution treatment chamber 211. The wastewater is separated from the oil in the wastewater by the oil film separation plate 214 through the blockage of the water distribution plate 213 and then falls into the wastewater treatment tank 1. In the second step, the water flow falls on the upper side of the pressure relief plate 241. Then, the groove rotating shaft 222 in the groove shaft chamber 221 rotates through the rotation of the rotating motor 223, and the flocculant particles in the storage bin 225 fall into the wastewater in the wastewater treatment tank 1 through the unloading rack 224. As the flocculation ends, the water quality sensor 31 senses the current water quality. After passing the standard, the flocculated impurities are filtered by the multi-stage filter screen 242, and the particulate impurities fall into the storage filter bin 243. At the same time, the water passing port 244 sucks the water, which passes through the activated carbon filter 245 and is discharged through the water pump 32. Finally, the water level sensor 23 senses that the current water level has dropped and controls the feed pump 212 to work again, thus completing the use process of a pretreatment precipitation device for treating high-concentration complex wastewater.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
