Description

Technical Field

[0001] This invention relates to the field of environmental accident wastewater treatment technology, specifically to a mobile environmental accident wastewater collection device. Background Technology

[0002] Currently, buildings in industrial plants that store hazardous chemicals or fuels, such as chemical warehouses, hazardous waste warehouses, and fuel source plants, often involve toxic and harmful substances. Their production processes are highly hazardous, posing significant environmental risks. When abnormal operating conditions or accidents occur, they can easily lead to sudden water pollution incidents. Enterprise water environment risk prevention and control measures play a crucial role in emergency response. After a production accident occurs in a factory, a large amount of high-concentration organic wastewater or toxic and harmful wastewater will be discharged in a short period of time. If this wastewater is directly discharged into the sewage treatment system, it will place a high impact load on the operating biological treatment system, and the resulting impact will take a long time to recover, sometimes causing fatal damage. To avoid the impact of accidental wastewater on the sewage treatment system, it is necessary to install environmental accident wastewater collection devices to store accidental wastewater.

[0003] However, existing wastewater collection devices for environmental accidents have limited functions, only able to perform simple sedimentation treatment on the collected wastewater. The wastewater still contains a large number of pollutants after sedimentation, making it difficult to reuse. This not only wastes water resources but also increases the burden on production enterprises. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a mobile wastewater collection device for environmental accidents.

[0005] The technical solution of the present invention is as follows: a mobile environmental accident wastewater collection device, comprising a collection tank, a water collection trough installed below the ground level and connected to the collection tank via a collection pipe, and a purification component installed inside the collection tank; a maintenance manhole is provided at the top of the collection tank and a support saddle is provided at the bottom; a magnetic float level gauge is provided at the end of the collection tank away from the water collection trough.

[0006] The water collection tank is equipped with a linkage float level switch. One end of the collection pipe is inserted into the water collection tank, and the other end passes through the collection tank and extends into the bottom of the collection tank. A water pump is installed on the collection pipe, and a PLC controller electrically connected to the water pump is installed on the side wall of the collection tank.

[0007] The purification assembly includes a lifting motor mounted at the top of the collection tank, a mounting frame inside the collection tank and connected to the lifting motor, an oil removal cylinder movably mounted inside the mounting frame, and a suspended solids collection screen box located below the mounting frame. A lifting screw, threaded through the collection tank and connected to the mounting frame, is mounted on the output shaft of the lifting motor. Movable seats are slidably engaged on both sides of the mounting frame, and electric push rods connected to the movable seats are mounted on the side walls of the mounting frame. A liquid level sensor electrically connected to a PLC controller is mounted on the mounting frame. The two ends of the oil removal cylinder are rotatably engaged with the two movable seats via rotating shafts. Both rotating shafts pass through the corresponding movable seats and are equipped with pinions. An oil-absorbing felt is fitted over the oil removal cylinder. A rack meshing with the pinions is located inside the mounting frame. The suspended solids collection screen box is connected to the two movable seats, and inwardly opening movable doors are movably hinged to the two symmetrical side walls of the suspended solids collection screen box. A return torsion spring is installed at the connection between the movable doors and the suspended solids collection screen box.

[0008] Furthermore, it also includes an ultraviolet photocatalytic disinfection component installed inside the collection tank; the ultraviolet photocatalytic disinfection component includes a fixing sleeve fitted inside the collection tank, an ultraviolet lamp tube installed inside the fixing sleeve, and a mesh cylinder installed on the side of the fixing sleeve away from the inner wall of the collection tank; the mesh cylinder is coated with a nano titanium dioxide coating.

[0009] Instructions: When using this product, the nano-titanium dioxide coating on the mesh tube is irradiated by an ultraviolet lamp. Under the irradiation of ultraviolet light, the nano-titanium dioxide undergoes electron transition to form hydroxyl groups. These hydroxyl groups then capture hydrogen atoms from the cell wall, generating CO2 and H2O, which are used to oxidize and sterilize the wastewater.

[0010] Furthermore, a feeding pipe is installed at the lower part of the inside of the collection tank. The feeding pipe passes through the collection tank and a feeding pump is installed at the connection between the feeding pipe and the collection tank. A cyclone pipe is rotatably connected to the end of the feeding pipe.

[0011] Note: After the wastewater from the environmental accident is collected, external acid-base regulators, flocculants, and other treatment agents are introduced into the collection tank through the feed pipe using a feed pump. This helps to improve the purification effect of the wastewater. At the same time, the agents diffuse more evenly in the wastewater under the action of the cyclone tube.

[0012] Furthermore, a settling baffle is provided at the bottom of the collection tank via a limiting frame, and a sludge discharge pipe is provided on the side wall of the collection tank below the settling baffle;

[0013] Explanation: Sludge and other impurities in the wastewater settle to the bottom of the collection tank through the sedimentation baffle, preventing water flow from disturbing the sedimentation. The settled sludge is eventually discharged from the collection tank through the sludge discharge pipe.

[0014] Furthermore, guide plates are inclinedly installed on the side walls of the collection cage and at positions corresponding to the two movable doors, and a collection net bag is movably attached to the bottom of the collection cage;

[0015] Note: By setting up the flow guide plate, the collection efficiency of the collection cage for suspended solids in wastewater can be improved; by setting up the collection net bag, it is easy to transfer suspended pollutants and ensure the long-term stable operation of the device.

[0016] Furthermore, water inlet platforms are installed at the connection points of the collection pipe, feeding pipe, and sludge discharge pipe with the collection tank;

[0017] Note: By setting up a water inlet platform, leakage of the collection tank is avoided by placing the pipeline on the arc surface of the collection tank.

[0018] Furthermore, two water pumps are installed on the collection pipe via branch pipes, and a circulation pipe and an output pipe are installed on the branch pipes. A first solenoid valve, a second solenoid valve, and a third solenoid valve are respectively installed on the collection pipe, the circulation pipe, and the output pipe.

[0019] Explanation: By setting up two water pumps, when the liquid level inside the collection tank reaches the middle level, the device automatically starts one water pump, and when it reaches the high level, both water pumps automatically start. When the liquid level drops to the low point, the water pumps are shut off, realizing the automatic operation of the equipment. By setting up circulation pipes and output pipes, closing the first solenoid valve, and opening the second and third solenoid valves, the water pumps discharge the sewage inside the collection tank through the output pipe, realizing the automatic input and output of environmental accident wastewater inside the collection tank.

[0020] Furthermore, the collection tank is made of fiberglass, and a protective layer is sprayed on the outer wall of the collection tank;

[0021] Note: The collection tanks made of fiberglass have excellent corrosion resistance. Furthermore, a protective coating is applied to the outer wall of the tank, further enhancing its aging resistance and UV resistance, extending its service life and reducing the company's cost.

[0022] Furthermore, a reflective sleeve is provided on the side of the fixing sleeve near the inner wall of the collection tank;

[0023] Note: By setting up a reflective sleeve, it is beneficial to improve the utilization efficiency of ultraviolet light by the nano-titanium dioxide coating and improve the ultraviolet disinfection efficiency of wastewater.

[0024] Furthermore, it also includes a dual power supply module that is electrically connected to each electrical device;

[0025] Note: Setting up a dual power supply module helps improve the operational reliability of the device.

[0026] The method of using this invention includes the following steps:

[0027] S1. Collect surface runoff wastewater from environmental accidents using a collection tank, and then use a water pump to inject the wastewater into the collection tank through a collection pipe. A linkage float level switch monitors the liquid level inside the collection tank. When the liquid level inside the collection tank reaches the middle level, a PLC controller starts one water pump. When the liquid level reaches the high level, the PLC controller starts two water pumps simultaneously. When the liquid level drops to the low point, the water pumps are shut off.

[0028] S2. After the wastewater from the environmental accident enters the collection tank, the oil removal cylinder and the suspended solids collection screen are moved horizontally inside the collection tank by an electric push rod. The suspended solids collection screen collects suspended pollutants in the wastewater. During the horizontal movement of the suspended solids collection screen, the lifting motor is started by the PLC controller. The lifting motor drives the lifting screw to rotate, thereby causing the mounting frame to move up and down along the lifting screw. The liquid level sensor senses the liquid level inside the collection tank and makes the oil removal cylinder finally located at the upper end of the liquid surface. The electric push rod pushes the moving seat to move on the mounting frame. At this time, the oil removal cylinder moves with the moving seat and rotates under the meshing action of the pinion and rack. The oil-absorbing felt absorbs the oil in the wastewater.

[0029] S4. Using ultraviolet lamps to irradiate the nano-titanium dioxide coating on the mesh cylinder, the nano-titanium dioxide undergoes electron transition to form hydroxyl groups under ultraviolet light. The hydroxyl groups capture hydrogen atoms from the cell wall to generate CO2 and H2O, which are then used to oxidize and sterilize the accident wastewater.

[0030] S5. Use a magnetic level gauge to observe the liquid level inside the collection tank. When the liquid level in the collection tank rises to the set value, close the first solenoid valve and open the second and third solenoid valves at the same time. Control the water pump to start through the PLC controller and use the water pump to discharge the sewage inside the collection tank through the output pipe. When the liquid level in the collection tank drops to the set value, control the water pump to stop through the PLC controller.

[0031] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0032] First, the present invention has a reasonable structural design. It uses a water collection tank to collect wastewater from environmental accidents and inputs the wastewater into the collection tank, thus avoiding pollution of the environment by the wastewater from environmental accidents. At the same time, it uses purification components and ultraviolet photocatalytic disinfection components to carry out deep purification treatment of wastewater from environmental accidents, which is conducive to improving the secondary utilization efficiency of wastewater from environmental accidents and protecting water resources.

[0033] Secondly, this invention, by setting a connecting rod float level switch inside the water collection tank and a magnetic float level gauge at the end of the collection tank, controls the number of working water pumps and the input and output status of the collection tank according to the changes in the liquid level inside the water collection tank and the collection tank, has a very high degree of automation and operational stability.

[0034] Third, the dual power supply module of the present invention ensures the reliable operation of each electrical device, thereby ensuring the continuous and efficient operation of the device and improving the response speed of the device in the event of an environmental accident.
