Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an industrial wastewater discharge treatment device. Background Technology

[0002] Industrial wastewater typically contains various pollutants such as heavy metals, organic matter, and suspended solids. Wastewater must be pre-treated to meet discharge standards before it can be legally discharged into the municipal sewer network. Direct discharge without pre-treatment will cause serious damage to the environment.

[0003] Currently, in enterprise production, industrial wastewater, after meeting discharge water quality standards, enters the municipal pipeline network and flows into the wastewater treatment plant, which ultimately undertakes the function of centralized wastewater treatment. Whether the wastewater discharge meets the standards mainly depends on the enterprise's own real-time monitoring of the discharge outlet. However, there is a lack of necessary water quality monitoring and emergency treatment measures from the enterprise's discharge outlet to the municipal pipeline network. There is still a risk that some wastewater exceeding the standards will enter the municipal pipeline network, which may lead to corrosion and damage to municipal pipelines, and in severe cases, cause environmental pollution accidents. Utility Model Content

[0004] The technical problem this utility model aims to solve is that enterprises lack necessary water quality monitoring and emergency treatment measures from their discharge outlets to the municipal pipe network, which poses a risk that some substandard wastewater may enter the municipal pipe network, potentially causing corrosion and damage to municipal pipes, or even environmental pollution accidents.

[0005] To solve the above-mentioned technical problems, this utility model provides a technical solution for an industrial wastewater discharge treatment device:

[0006] The industrial wastewater discharge treatment device includes a main shell, an inlet pipe, an outlet pipe, a chemical storage tank, and a controller. The main shell is internally divided into an inlet chamber and an outlet chamber. The inlet pipe is located on one side of the main shell and connects to the inlet chamber, and the outlet pipe is located on the other side of the main shell and connects to the outlet chamber.

[0007] The main housing is provided with a first channel and a second channel, which are arranged in parallel and connect the water inlet chamber and the water outlet chamber; the first channel is provided with a first shut-off structure and the second channel is provided with a second shut-off structure.

[0008] The medicine storage tank is located outside the main shell and is connected to the second channel by a dosing pipe. The water inlet chamber is equipped with an inlet water quality detector. The controller is electrically connected to the inlet water quality detector, the first cut-off structure and the second cut-off structure respectively.

[0009] The controller is configured to: open the first cut-off structure and close the second cut-off structure when the influent water quality does not exceed the discharge standard value; and close the first cut-off structure and open the second cut-off structure when the influent water quality exceeds the discharge standard value.

[0010] Furthermore, the second channel is provided with at least two baffles, which are distributed at intervals along the length of the second channel, and adjacent baffles are alternately arranged on the two side walls of the second channel.

[0011] Furthermore, the first shut-off structure includes a first inlet gate and a first outlet gate, the first inlet gate being located on the side of the first channel near the inlet chamber, and the first outlet gate being located on the side of the first channel near the outlet chamber; the second shut-off structure includes a second inlet gate and a second outlet gate, the second inlet gate being located on the side of the second channel near the inlet chamber, and the second outlet gate being located on the side of the second channel near the outlet chamber.

[0012] Furthermore, a first partition is provided on the side of the water inlet chamber away from the water inlet pipe, and a second partition is provided on the side of the water outlet chamber away from the water outlet pipe. The main housing also includes a bottom wall, and the first partition and the second partition are respectively arranged vertically and vertically with respect to the bottom wall.

[0013] Furthermore, a third partition is provided between the first partition and the second partition, and the third partition is fixedly connected to the bottom wall. The first channel and the second channel are distributed on both sides of the third partition.

[0014] Furthermore, the first inlet gate is installed on the lower side of the first partition and corresponds to the first channel, and the second inlet gate is installed on the lower side of the first partition and corresponds to the second channel;

[0015] The second outlet gate is installed on the lower side of the second partition and corresponds to the first channel.

[0016] Furthermore, the outlet chamber is equipped with an outlet water quality detector, and the controller is electrically connected to the outlet water quality detector. The controller is also configured to receive the detection result of the outlet water quality detector and control the amount of medicine added from the storage tank to the second channel according to the outlet water quality.

[0017] Furthermore, the inlet pipe is equipped with an inlet electric valve, the outlet pipe is equipped with an outlet electric valve, and the controller is electrically connected to the inlet electric valve and the outlet electric valve respectively.

[0018] Furthermore, the influent water quality detector includes a pH sensor and a heavy metal sensor, and there are two storage tanks, one for storing acid-base adjustment solution and the other for storing heavy metal removal solution.

[0019] Compared with existing technologies, the industrial wastewater discharge treatment device of this utility model has the following advantages: The device adopts a design consisting of a main shell, an inlet pipe, an outlet pipe, a chemical storage tank, and a controller. The main shell is internally divided into an inlet chamber and an outlet chamber. The inlet pipe is located on one side of the main shell and connects to the inlet chamber, while the outlet pipe is located on the other side and connects to the outlet chamber. The inlet pipe is connected to the wastewater discharge outlet, and the outlet pipe is connected to the municipal pipeline. This device constitutes the final monitoring and treatment process for industrial wastewater before it enters the municipal pipe network. A first channel and a second channel are connected in parallel between the inlet and outlet chambers. The first channel has a first shut-off structure, and the second channel has a second shut-off structure. The inlet chamber is equipped with an inlet water quality detector, which monitors the inlet water quality in real time. The controller automatically adjusts the wastewater flow direction and treatment method based on whether the detection results exceed the discharge standards.

[0020] When the water quality meets the standards, the controller opens the first shut-off structure and closes the second shut-off structure. Wastewater flows directly from the inlet chamber to the outlet chamber through the first channel, eliminating the need for chemical treatment and reducing chemical costs. When the water quality exceeds the standards, the controller closes the first shut-off structure and opens the second shut-off structure. Wastewater is switched to the second channel, and chemicals are simultaneously added from the storage tank and dosing pipe to the second channel to ensure the effluent meets the discharge standards before being discharged through the outlet chamber.

[0021] Furthermore, this industrial wastewater treatment device integrates detection, diversion, dosing, and control functions into a single unit, reducing equipment footprint and piping complexity. Water quality detection and channel switching are automatically completed by the controller, enabling timely switching of wastewater exceeding standards to the second channel for dosing treatment. The first and second channels are connected in parallel and isolated by a shut-off structure. When wastewater undergoes dosing treatment in the second channel, the first channel is closed to prevent untreated wastewater exceeding standards from mixing with wastewater undergoing dosing treatment, ensuring stable and reliable effluent quality. This effectively avoids the risk of some wastewater exceeding standards entering the municipal pipe network, preventing potential corrosion and damage to municipal pipelines and environmental pollution.

[0030] like Figures 1 to 3 As shown, an industrial wastewater discharge treatment device according to an embodiment of the present invention includes a main shell 1, an inlet pipe 2, an outlet pipe 3, a chemical storage tank 4, and a controller 5. The main shell 1 is internally provided with an inlet chamber 11 and an outlet chamber 12. The inlet pipe 2 is located on one side of the main shell 1 and connects to the inlet chamber 11, and the outlet pipe 3 is located on the other side of the main shell 1 and connects to the outlet chamber 12. The main shell 1 is provided with a first channel 13 and a second channel 14, which are arranged in parallel and connect the inlet chamber 11 and the outlet chamber 12. The first channel 13 is provided with a first shut-off structure 15, and the second channel 14 is provided with a second shut-off structure 16.

[0031] The medicine storage tank 4 is located outside the main shell 1 and is connected to the second channel 14 by a dosing pipe 40. The water inlet chamber 11 is equipped with an inlet water quality detector 6. The controller 5 is electrically connected to the inlet water quality detector 6, the first cut-off structure 15, and the second cut-off structure 16. The controller 5 is configured to: control the first cut-off structure 15 to open and the second cut-off structure 16 to close when the inlet water quality does not exceed the discharge standard value; and control the first cut-off structure 15 to close and the second cut-off structure 16 to open when the inlet water quality exceeds the discharge standard value.

[0032] This industrial wastewater treatment device adopts a design consisting of a main shell 1, an inlet pipe 2, an outlet pipe 3, a chemical storage tank 4, and a controller 5. The main shell 1 is internally divided into an inlet chamber 11 and an outlet chamber 12. The inlet pipe 2 is located on one side of the main shell 1 and connects to the inlet chamber 11, while the outlet pipe 3 is located on the other side of the main shell 1 and connects to the outlet chamber 12. The inlet pipe 2 is connected to the wastewater discharge outlet, and the outlet pipe 3 is connected to the municipal pipeline. This device constitutes the final monitoring and treatment process for industrial wastewater before it enters the municipal pipe network. A first channel 13 and a second channel 14 are connected in parallel between the inlet chamber 11 and the outlet chamber 12. The first channel 13 has a first shut-off structure 15, and the second channel 14 has a second shut-off structure 16. The inlet chamber 11 is equipped with an inlet water quality detector 6, which monitors the inlet water quality in real time. The controller 5 automatically adjusts the wastewater flow direction and treatment method based on whether the detection results exceed the discharge standard values.

[0033] When the water quality meets the standards, controller 5 opens the first shut-off structure 15 and closes the second shut-off structure 16. The wastewater flows directly from the inlet chamber 11 to the outlet chamber 12 through the first channel 13, eliminating the need for chemical treatment and reducing the cost of chemical agents. When the water quality exceeds the standards, controller 5 closes the first shut-off structure 15 and opens the second shut-off structure 16. The wastewater switches to the second channel 14, and simultaneously, chemicals are added to the second channel 14 from the storage tank 4 and the dosing pipe 40 to ensure that the effluent meets the discharge standards before being discharged through the outlet chamber 12.

[0034] Furthermore, this industrial wastewater treatment device integrates detection, diversion, dosing, and control functions into a single unit, reducing equipment footprint and piping complexity. Water quality detection and channel switching are automatically completed by controller 5, enabling timely switching of wastewater exceeding standards to the second channel 14 for dosing treatment. The first channel 13 and the second channel 14 are connected in parallel and isolated by a shut-off structure. When wastewater undergoes dosing treatment in the second channel 14, the first channel 13 is closed to prevent untreated wastewater exceeding standards from mixing with wastewater undergoing dosing treatment, ensuring stable and reliable effluent quality. This effectively avoids the risk of some wastewater exceeding standards entering the municipal pipe network, preventing potential corrosion and damage to municipal pipelines and environmental pollution.

[0035] In this embodiment, at least two baffles 131 are provided in the second channel 14. The at least two baffles 131 are distributed at intervals along the length of the second channel 14, and adjacent baffles 131 are alternately arranged on the two side walls of the second channel 14. The at least two baffles 131 form a tortuous water flow path in the second channel 14, which prolongs the flow time of the sewage exceeding the standard in the second channel 14, thereby ensuring the mixing and reaction effect of the sewage exceeding the standard and the reagent.

[0036] As a further preferred embodiment, the first shut-off structure 15 includes a first inlet gate 151 and a first outlet gate 152. The first inlet gate 151 is located on the side of the first channel 13 near the inlet chamber 11, and the first outlet gate 152 is located on the side of the first channel 13 near the outlet chamber 12. The second shut-off structure 16 includes a second inlet gate 161 and a second outlet gate 162. The second inlet gate 161 is located on the side of the second channel 14 near the inlet chamber 11, and the second outlet gate 162 is located on the side of the second channel 14 near the outlet chamber 12. The inlet and outlet gates have simple structures, facilitating timely control of the opening or closing of the first channel 13 and the second channel 14.

[0037] A first partition 17 is provided on the side of the water inlet chamber 11 away from the water inlet pipe 2, and a second partition 18 is provided on the side of the water outlet chamber 12 away from the water outlet pipe 3. The main shell 1 also includes a bottom wall, with the first partition 17 and the second partition 18 arranged vertically and vertically on the bottom wall, respectively. Furthermore, a third partition 19 is provided between the first partition 17 and the second partition 18, and the third partition 19 is fixedly connected to the bottom wall. A first channel 13 and a second channel 14 are distributed on both sides of the third partition 19. By utilizing the first partition 17, the second partition 18, and the third partition 19, two chambers and two channels are formed inside the main shell 1, resulting in a simpler and more compact structural design.

[0038] Specifically, the first inlet gate 151 is installed on the lower side of the first partition 17 and corresponds to the first channel 13; the second inlet gate 161 is installed on the lower side of the first partition 17 and corresponds to the second channel 14; the second outlet gate 162 is installed on the lower side of the second partition 18 and corresponds to the first channel 13; the second outlet gate 162 is installed on the lower side of the second partition 18 and corresponds to the second channel 14.

[0039] Furthermore, the effluent chamber 12 is equipped with an effluent water quality detector 7, and the controller 5 is electrically connected to the effluent water quality detector 7. The controller 5 is also configured to receive the detection results from the effluent water quality detector 7 and control the dosage of chemicals from the storage tank 4 to the second channel 14 according to the effluent water quality. Specifically, the dosing pipe 40 is equipped with a flow valve 41, and the controller 5 is also electrically connected to the flow valve 41. If the detected effluent water quality still exceeds the discharge standard value, the controller 5 controls the flow valve 41 to increase the corresponding amount of chemical added; conversely, the controller 5 controls the flow valve 41 to decrease the corresponding amount of chemical added, thereby ensuring that the discharge meets the standards through secondary water quality detection.

[0040] In addition, an inlet electric valve 21 is installed on the inlet pipe 2, and an outlet electric valve 31 is installed on the outlet pipe 3. The controller 5 is electrically connected to the inlet electric valve 21 and the outlet electric valve 31, respectively. Furthermore, the inlet water quality detector 6 includes a pH sensor 61 and a heavy metal sensor 62. Two storage tanks 4 are provided: one for storing acid-base adjustment solution and the other for storing heavy metal removal solution. When the pH sensor 61 detects that the pH value of the inlet water exceeds the standard, it controls one storage tank 4 to add acid-base adjustment solution to the second channel 14 to balance the pH value of the inlet water. Correspondingly, when the heavy metal sensor 62 detects that the pH value of the wastewater exceeds the standard, it controls the other storage tank 4 to add heavy metal removal solution to the second channel 14 to reduce the concentration of heavy metal ions in the wastewater to meet the discharge standard value.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
