Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, and specifically relates to a novel desulfurized wastewater treatment device. Background Art

[0002] Wastewater treatment is to purify the wastewater generated in the processes such as production and life, so that it reaches a certain water quality standard, in order to reduce environmental pollution and realize the recycling or safe discharge of water resources. Some wastewater contains sulfur compounds. After being directly discharged without desulfurization treatment, it may be converted into harmful gases such as hydrogen sulfide and released into the atmosphere under certain conditions, causing air pollution. Hydrogen sulfide has a strong pungent smell, is harmful to human health, and may also cause dangerous situations such as poisoning at higher concentrations. Therefore, a desulfurized wastewater treatment device is needed to desulfurize the wastewater.

[0003] In the prior art, such as the "desulfurized wastewater treatment device" with the patent number CN215327399U, it includes a buffer tank, a modification tank, a sedimentation tank, a clarification tank and an outlet tank. An intermediate partition net is arranged in the buffer tank. An inlet pipe is arranged above the inner cavity on one side of the partition net. A water pump is arranged at the bottom of the inner cavity on the other side of the intermediate partition net. The bottom of the inner cavity of the modification tank is a semi-circular bottom. A stirring device is arranged in the modification tank. The stirring device includes a rotating shaft. One end of the rotating shaft is provided with impact rotating blades, and the other end is provided with stirring blades. An inlet pipe of the modification tank is arranged above the impact rotating blades. The inlet pipe is communicated with the water pump. The outlet of the inlet pipe is located above the impact rotating blades on one side of the rotating shaft. A feeding port is arranged above the modification tank. The modification tank has an outlet pipe, and the outlet pipe is located at the transition connection between the semi-circular bottom and the upper part of the modification tank, which can facilitate the cleaning of sediments while ensuring the water quality treatment effect without shutting down, and there is no desulfurized wastewater treatment device that improves the sewage treatment speed;

[0004] At present, desulfurized wastewater is generally treated by the "three-compartment box" process. The wastewater treatment system includes a wastewater buffer tank system, a clarification tank and an outlet buffer (clean water tank) box system, a sludge circulation system, a sludge pressure filtration system, an organic sulfur dosing system, a flocculant dosing system, a coagulant aid dosing system, a hydrochloric acid dosing system, a lime milk preparation system and a lime milk dosing system, etc. After dosing, precipitation occurs. There are many dosing systems. When each system discharges materials separately, it will cause the internal solution to surge and roll, reducing the sedimentation effect, and then affecting the desulfurized wastewater treatment efficiency. Moreover, the number of devices is large, which not only increases the equipment maintenance workload, but also has a high cost. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present utility model provides a new desulfurized wastewater treatment device. On the basis of the original desulfurized wastewater treatment system, relatively complex equipment and facilities are removed, and in the form of centralized layout, by integrating each equipment and system for wastewater disposal into a single integrated system, the number of equipment is reduced, and the purpose of wastewater disposal is achieved through fully automatic optimization control.

[0006] To achieve the above objectives, the present utility model is realized through the following technical solutions: A new desulfurized wastewater treatment device, including a clear water tank, in which the wastewater after concentration and clarification is filled. The water outlet end of the clear water tank is connected to an integrated treatment device through a conveying mechanism. A detachable top cover is installed at the top of the integrated treatment device. The top cover has a hollow structure inside, and an inlet and a drain outlet are opened at the bottom. A feed port for injecting a medicament that can prompt fine particles in the wastewater to quickly coagulate into larger flocs is opened at the upper end of the integrated treatment device.

[0007] The integrated treatment device includes four sedimentation chambers connected in series with each other and a sludge storage tank in an inverted conical shape. A sludge discharge port is provided at the bottom end of each sedimentation chamber. The four sludge discharge ports are all connected to the inlet of the sludge storage tank and are used to collect the sludge into the sludge storage tank. A sludge discharge port is provided at the bottom of the sludge storage tank. The bottom end of the sludge discharge port is connected to a sludge discharge pipe. An automatic sludge discharge valve is arranged on the outer surface of the sludge discharge pipe. The sludge discharge end of the sludge discharge pipe is connected to a sludge pool. A water outlet tank for collecting the water overflowing from the top cover is installed on one side of the sludge pool.

[0008] Preferably, four brackets arranged in a circular pattern are installed between the integrated treatment device and the sludge pool.

[0009] Preferably, a sludge pumping pump is installed on one side of the sludge pool. The sludge pumping pump transports the sludge in the sludge pool to the desulfurized gypsum vacuum belt machine outside through a sludge pumping pipe.

[0010] Preferably, the drain end of the drain outlet is connected to a drain pipe. One end of the drain pipe is connected to a hose for draining water to the water outlet tank.

[0011] Preferably, a medicament tank filled with DBS is connected to the upper surface of the top cover and is injected into the four sedimentation chambers through the feed port.

[0012] Preferably, the conveying mechanism includes a water pump, a water pipe A and a water pipe B. One end of the water pipe A is connected to the clear water tank, and the other end is connected to the inlet end of the water pump. The inlet end of the water pipe B is connected to the outlet end of the water pump. The outlet end of the water pipe B is connected to the sedimentation chamber closest to it.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] The new desulfurized wastewater treatment device integrates various equipment and systems for wastewater treatment into a single integrated system by setting up an integrated treatment equipment, reducing the number of equipment. On the basis of the original desulfurized wastewater treatment system, relatively complex equipment and facilities are removed, and in the form of centralized layout, each subsystem is integrated into an integrated treatment system, including a series of sedimentation chambers. The mud discharge ports of each sedimentation chamber are connected to the inlets of the sludge storage tanks. The sludge hoppers enable the sludge in the four sedimentation chambers to settle quickly and directly enter the sludge storage tanks for further sedimentation separation. Moreover, there is no need to separately set automatic valves to control the discharge of each sedimentation chamber, and only an automatic sludge discharge valve needs to be set on the sludge discharge pipe. On the one hand, it prevents the solution in the sedimentation chamber from surging and tumbling when each sedimentation chamber discharges separately, improving the sedimentation effect. On the other hand, it reduces the number of multiple automatic sludge discharge valves, saving the cost of the entire device. Description of the Drawings

Detailed Embodiment

[0020] Such as Figures 1 - 4As shown in the figure, a new desulfurized wastewater treatment device includes a clear water tank 1. The clear water tank 1 is filled with wastewater after concentration and clarification. The water outlet end of the clear water tank 1 is connected to an integrated treatment device 2 through a conveying mechanism 20. The conveying mechanism 20 includes a water pump, a water pipe A and a water pipe B. One end of the water pipe A is connected to the clear water tank 1, and the other end is connected to the water inlet end of the water pump. The water inlet end of the water pipe B is connected to the water outlet end of the water pump, and the water outlet end of the water pipe B is connected to the sedimentation chamber 7 close to it. Through the water pump, the water pipe A and the water pipe B, the water in the clear water tank 1 is conveyed into the sedimentation chamber 7. The top of the integrated treatment device 2 is equipped with a detachable top cover 3. The interior of the top cover 3 is provided with a hollow structure, and an inlet 4 and a drain 5 are opened at the bottom. The inlet 4 is annular. The drainage end of the drain 5 is connected to a drain pipe 17. One end of the drain pipe 17 is connected to a hose 18 for draining water to the outlet water tank 14. An inlet 6 for injecting a chemical agent that can prompt fine particles in the wastewater to quickly agglomerate into larger flocs is opened at the upper end of the integrated treatment device 2. The upper surface of the top cover 3 is connected to a chemical agent tank 19 filled with DBS, and the chemical agent is injected into the four sedimentation chambers 7 through the inlet 6.

[0021] The integrated treatment device 2 includes four sedimentation chambers 7 connected in series with each other and a sludge storage tank 8 in an inverted conical shape. A sludge discharge port 9 is provided at the bottom end of each sedimentation chamber 7. The four sludge discharge ports are all connected to the inlet of the sludge storage tank 8 and are used to collect sludge into the sludge storage tank 8. A sludge discharge port 10 is provided at the bottom of the sludge storage tank 8. The bottom end of the sludge discharge port 10 is connected to a sludge discharge pipe 11. An automatic sludge discharge valve 12 is arranged on the outer surface of the sludge discharge pipe 11. The sludge discharge end of the sludge discharge pipe 11 is connected to a sludge pool 13. Four brackets 15 arranged in a circular pattern are installed between the integrated treatment device 2 and the sludge pool 13 to improve the stability between the integrated treatment device 2 and the sludge pool 13. A sludge pump 16 is installed on one side of the sludge pool 13. The sludge pump 16 conveys the sludge in the sludge pool 13 to the external desulfurized gypsum vacuum belt filter through a sludge suction pipe. In the desulfurization system, the gypsum slurry contains a large amount of water. The vacuum belt filter forms a vacuum environment under the filter cloth and uses the pressure difference to prompt the water in the gypsum slurry to pass through the filter cloth and be pumped out, thereby realizing solid-liquid separation. An outlet water tank 14 for collecting the water overflowing from the top cover 3 is installed on one side of the sludge pool 13. By setting the sludge storage tank 8, the sludge in the four sedimentation chambers 7 can quickly settle and directly enter the sludge storage tank 8 for further sedimentation and separation. Moreover, the sedimentation chamber 7 does not need to be separately provided with an automatic valve to control the discharge. Only an automatic sludge discharge valve 12 needs to be set on the sludge discharge pipe 11. On the one hand, it prevents the solution in the sedimentation chamber 7 from surging and tumbling when the sedimentation chamber 7 discharges separately, improving the sedimentation effect. On the other hand, it reduces the number of multiple automatic sludge discharge valves 12, saving the cost of the entire device.

[0022] In use, first, the wastewater to be treated is processed through an external concentration clarification tank. The wastewater and foreign matters at the bottom are discharged into an underground tank and returned to the external filtrate water tank. The water overflowing from the concentration clarification tank enters the clean water tank 1 in this device. Then, the water in the clean water tank 1 is pumped through the water pipe A and sequentially enters one of the sedimentation chambers 7 in the integrated processing equipment. Since the four sedimentation chambers 7 are connected in series, the incoming water is diverted into the four sedimentation chambers 7. At this time, it is necessary to control the DBS material in the chemical agent tank 19 through an external automation system to be sequentially injected into the connection between the top cover 3 and the chemical agent tank 19, the feeding port 6, and then enter the four sedimentation chambers 7 respectively. The DBS material is used to prompt the fine particles in the wastewater to quickly aggregate into larger flocs. These larger flocs start to settle and are respectively collected from the four sludge discharge ports 9 into the inlet of the sludge storage tank 8 for further sedimentation separation. By opening the automatic sludge discharge valve 12 at the sludge discharge pipe 11, the sludge can be discharged into the sludge tank 13, thus realizing the rapid sedimentation of the sludge in the four sedimentation chambers 7 and directly entering the sludge storage tank 8 for further sedimentation separation. Moreover, there is no need to separately set an automatic valve to control the discharge of the sedimentation chamber 7. Only one automatic sludge discharge valve 12 needs to be set at the sludge discharge pipe 11. On the one hand, it prevents the solution in the sedimentation chamber 7 from surging and tumbling when each sedimentation chamber 7 discharges separately, improving the sedimentation effect. On the other hand, it reduces the number of multiple automatic sludge discharge valves 12, saving the cost of the entire device.

[0023] Immediately afterwards, the sludge in the sludge tank 13 is transported to an external desulfurized gypsum vacuum belt filter through the sludge pump 16 and the sludge discharge pipe. Then, the water overflowing from the four sedimentation chambers 7 enters the interior of the top cover 3 from the water inlet 4 of the top cover 3, and then is discharged into the outlet water tank 14 through the drain pipe 17 and the hose 18 from the drain outlet 5 of the top cover 3.
