[0002] Highway construction spans a wide area and has a wide impact range. It inevitably crosses large lakes, water source protection areas and other surface water bodies with important functional levels. Road and bridge runoff contains a variety of pollutants. During daily traffic operations, particulate matter and heavy metals such as lead, zinc, and cadmium in vehicle exhaust and leaked oil substances such as motor oil and gasoline will settle on the road surface. When it rains, these pollutants will be washed into the surrounding water bodies with the runoff. In addition, heavy metal pollution caused by road and bridge runoff will have a negative impact on the survival and reproduction of aquatic organisms and may change the structure and function of aquatic ecosystems.

[0003] In addition, solid waste such as garbage, dust and debris from road wear will also enter the water body with runoff, increasing the turbidity of the water and affecting the appearance and self-purification ability of the water.

[0040] The treatment device is used for collecting initial rainwater and waste liquid from leakage of hazardous chemicals, and includes a collection box 100, an emergency room 110 independently arranged in the collection box 100, a sedimentation chamber 120, an equipment room 130, a water distribution tank 200 arranged on the top of the equipment room 130, and a flocculation chamber 140 separated from the sedimentation chamber 120. A through groove is opened between the sedimentation chamber 120 and the top partition of the flocculation chamber 140 for overflowing the upper water of the flocculation chamber 140 into the sedimentation chamber 120 for sedimentation treatment.

[0041] Among them, the emergency room 110 is adapted to be equipped with a pollution pool 111 for temporarily collecting waste liquid leaked from hazardous chemicals. When it is full, the management personnel will pump out and empty it, so that as little waste liquid as possible flows into the drainage pipe; the sedimentation chamber 120 is adapted to be equipped with a sedimentation tank 121 for collecting initial rainwater. At the initial stage of rain, general impurities on the road surface and bridge deck will be drained to the sedimentation tank 121 for sedimentation treatment. Even if the sedimentation tank 121 is full, this equipment will no longer collect rainwater. At this time, the rainwater is clear and free of impurities, and can flow into the drainage pipe.

[0042] Among them, a clean water tank 122 is arranged at the top of the equipment room 130 and on one side of the water distribution tank 200, which is used to transfer the clean water in the sedimentation tank 121; a drain pipe 124 is arranged at the bottom wall of the equipment room 130 for quickly draining the rainwater inside the sedimentation tank 121, so that the sedimentation tank 121 can free up space for collecting polluted rainwater; a water collecting trough 126 is set between the top of the sedimentation chamber 120 to drain the upper clean water of the sedimentation tank 121 into the clean water tank 122, and a through hole is opened at one end of the water collecting trough 126 and the top side wall of the clean water tank 122, which is used to overflow the upper water of the sedimentation tank 121 into the clean water tank 122.

[0044] Furthermore, the bottom of the water distribution tank 200 is connected to a pollution pool water inlet pipe 112 extending to the pollution pool 111, and a liquid outlet is provided on the top surface of the collection box 100 and located above the pollution pool 111, and the leaked waste liquid of hazardous chemicals in the pollution pool 111 is sucked out through the liquid outlet by a water pump.

[0045] Furthermore, a water outlet pipe 1221 is connected to the bottom of the clean water tank 122, and the top of the water outlet pipe 1221 extends close to the top port of the clean water tank 122, so that when the clean water tank 122 is almost full, the water overflows and is automatically discharged through the water outlet pipe 1221; the emptying pipe 124 and the water outlet pipe 1221 are both concentratedly penetrated from one side of the equipment room 130 so as to be concentratedly connected to the ground drainage pipe; one side of the bottom of the water outlet pipe 1221 is connected to a drain pipe 1222 for draining the bottom water of the sedimentation tank 121. When the sedimentation tank 121 has been precipitated for a period of time, the water inside it is actively controlled to be discharged through the drain pipe 1222 to ensure that there is space in the sedimentation tank 121 for further collection.

[0046] Specifically, a water distribution tank drain pipe 210 and an overflow pipe 220 are connected to the bottom of the water distribution tank 200, and the top of the overflow pipe 220 is close to the top port of the water distribution tank 200, so that when the water distribution tank 200 is almost full, the overflow can be automatically discharged through the overflow pipe 220; the volume of the water distribution tank 200 is sufficient to accommodate 25 minutes of rainfall in previous years. Even if the rainfall exceeds the maximum processing capacity of the water distribution tank 200, the initial rainwater with impurities or waste liquid from leakage of hazardous chemicals has been collected; thereby, the initial rainwater is effectively intercepted and treated, reducing the pollution load of the ground drainage system, and helping to promote green transportation and sustainable development.

[0047] Furthermore, solenoid valves are installed on the water distribution tank drain pipe 210 and the overflow pipe 220, the top side wall of the clean water tank 122 is plugged with a water collecting pipe 125, and the bottom end of the water collecting pipe 125 passes through the bottom side wall of the sedimentation tank 121, and a water replenishment pump is installed at the bottom of the water collecting pipe 125 for actively collecting water in the sedimentation tank 121; the water distribution tank drain pipe 210 and the overflow pipe 220 are both concentrated from one side of the equipment room 130 so as to be concentrated into the ground drainage pipe.

In the flocculation stage, PAC and PAM flocculants are added through the dosing system, and the suspended matter and colloidal particles in the sewage are condensed into larger flocs, which sink to the bottom of the pool due to gravity, and the mud discharge plates 141 collect the sludge; a nozzle is installed at the port of the flushing pipe 143 for flushing the mud discharge plates 141 for cleaning.

[0050] Specifically, a medicine storage barrel 300 and a feeder 310 for supplying medicine to the flocculation chamber 140 are installed inside the equipment room 130. A pipe connected to the top of the medicine storage barrel 300 is provided at the bottom of the feeder 310, and a spiral rod is installed in the pipe, and a motor is coaxially connected to the outer end of the spiral rod. The motor is started to control the spiral rod to transport medicine into the medicine storage barrel 300.

[0051] Furthermore, the bottom of the clean water tank 122 is connected to a medicine barrel water inlet pipe 123, through which clean water mixed with medicine is added to the medicine barrel 300 to form a medicine solution; a metering water pump is installed on the top of the medicine barrel 300, and a dosing pipe 1231 is connected to the water outlet end of the metering water pump, and the outer end of the dosing pipe 1231 is connected to the middle side wall of the flocculation chamber water inlet pipe 142, and a solenoid valve is installed on the upper middle part of the flocculation chamber water inlet pipe 142, a solenoid valve is installed on the flushing pipe 143, and a solenoid valve is installed on the medicine barrel water inlet pipe 123.

[0052] It is worth noting that the solenoid valves, motors and water pumps used above are all arranged within the equipment room 130 for unified control and management.

[0053] In addition, the intelligent control system is used to monitor the liquid level, water quality, and solenoid valve status in real time, and remotely control the operation of the valve medicine storage barrel 300 and the feeder 310, including a remote operation module, a data transmission module, and an early warning device; its working process covers functions such as data collection, analysis and decision-making, automatic control, early warning, and remote operation. The specific process is as follows:

[0054] ① Data collection and transmission, liquid level monitoring: float level gauges or ultrasonic level gauges are installed in the water distribution tank 200, flocculation chamber 140, sedimentation tank 121, clean water tank 122 and pollution tank 111 to monitor the water level in each tank in real time;

[0055] Water quality monitoring: Turbidity sensors are installed above and below the sedimentation tank 121 to detect whether the water quality meets the standards;

[0056] Flow monitoring: An electromagnetic flow meter is installed at the water inlet of the water distribution tank 200 to count the real-time runoff; a flow meter is installed at the outlet pipe 1221 of the clean water tank 122 to monitor the discharge volume;

[0057] Equipment status monitoring: The switch status of the solenoid valves, motors, and water pumps of all pipelines is fed back to the system through current sensors;

[0058] Data transmission: The above sensor data is transmitted to the cloud server or local control center in real time via 4G / 5G or fiber optic network; a dual-channel redundant design is adopted to ensure that the data is temporarily stored in the local PLC when the network is interrupted, and automatically retransmitted after recovery.

[0059] ②Data analysis and decision logic, threshold judgment flow classification: According to the electromagnetic flow meter data, determine whether the current runoff belongs to mode 1, mode 2 or mode 3;

[0060] Mode 1: Rainwater flow without waste liquid is less than the equipment processing capacity, and continuous operation is sufficient;

[0061] Mode 2: When the rainwater flow without waste liquid is greater than or equal to the processing volume, the solenoid valve of the overflow pipe 220 of the water distribution tank 200 is opened to process the rainwater collected in the early stage. The road and bridge surface has been washed clean by the subsequent rainwater and can be directly discharged into the ground drainage pipe;

[0062] Mode 3: When rainwater from hazardous chemical leakage occurs on the road or bridge deck, it is first collected in the pollution pool 111 and then collected in the sedimentation pool 121. If the sedimentation pool 121 is full, it is actively overflowed and discharged through the water distribution tank 200, and subsequent rainwater is no longer collected. Since a large amount of waste liquid has been temporarily stored, the subsequent rainwater that washes the road or bridge deck has reduced pollution, and discharging it into the ground drainage pipe can reduce its load.

[0063] ③ Automatic control execution, switching the solenoid valve according to the operation mode, normal runoff: open the solenoid valve leading to the flocculation chamber water inlet pipe 142 from the water distribution tank 200, and close the solenoid valve leading to the pollution tank water inlet pipe 112;

[0064] Waste liquid from hazardous chemical leakage: After receiving the leakage signal, the intelligent control system remotely closes the solenoid valve of the overflow pipe 220 and opens the solenoid valve of the pollution pool water inlet pipe 112. When the pollution pool 111 is full, the flocculation chamber water inlet pipe 142 is opened to introduce the waste liquid into the sedimentation tank 121;

[0065] ④ Early warning and alarm mechanism, abnormal water quality: turbidity>50NTU, triggering sound and light alarm and sending SMS to management personnel;

[0066] Liquid level exceeds limit: When the liquid level in pollution pool 111 reaches 90% of capacity, an early warning is activated to notify the pumping department;

[0067] Equipment failure: If the equipment current is abnormal or the solenoid valve response times out, the faulty equipment will be marked and a maintenance work order will be pushed.

[0068] ⑤ Remote operation and visual monitoring, human-machine interface (HMI): Display real-time data on the PC or mobile phone APP, such as liquid level curve, water quality parameters, and equipment status; provide manual control options, such as forcing the solenoid valve to switch the operating mode;

[0069] Historical data backtracking: Stores at least 1 year of operating data and supports the generation of pollution load reports, equipment utilization analysis and other reports.

[0070] The present invention also provides a method for collecting and monitoring road and bridge surface runoff based on liquid recycling, using the above-mentioned integrated equipment for collecting and monitoring road and bridge surface runoff based on liquid recycling, comprising the following steps: the runoff of the road surface and bridge surface during rain is guided to a water distribution tank 200 through a runoff collection system for collection;

[0071] There are three operation modes for treating rainwater. In mode 1, when the rainwater runoff is lower than the treatment capacity of the water distribution tank 200 to deliver water to the flocculation chamber 140, it will run continuously to treat all the rainwater and empty the flocculation chamber 140 in time.

[0072] Mode 2: When the rainwater runoff exceeds the treatment capacity of the water distribution tank 200 to the flocculation chamber 140, the maximum treatment capacity is maintained, and the excess water overflows and is discharged through the overflow pipe 220 in the water distribution tank 200. At this time, the rainwater containing the leaked hazardous chemical waste liquid has been collected by the water distribution tank 200.

[0073] Specifically, the electromagnetic valve of the flocculation chamber water inlet pipe 142 is opened, and the electromagnetic valve of the pollution pool water inlet pipe 112 entering the pollution pool 111 is closed, and the rainwater collected in the water distribution tank 200 is transported to the flocculation chamber 140; at the same time, the metering water pump on the medicine storage barrel 300 is started to pump the medicine liquid into the flocculation chamber water inlet pipe 142 through the medicine adding pipe 1231, and enter the flocculation chamber 140 for flocculation and precipitation, and the upper layer of water in the flocculation chamber 140 overflows to the sedimentation tank 121 for further precipitation. After the water quality meets the requirements, the water replenishment pump is started to pump the precipitated water in the sedimentation tank 121 into the clean water tank 122, and then overflows through the outlet pipe 1221; the sludge precipitated in the sedimentation tank 121 is collected and filtered with geobags, and the filtrate can be collected or discharged naturally according to the on-site environment. The sludge in the geobag is regularly bagged and transported away by the management personnel;

[0074] Mode three, when the management personnel receives a notification through mobile phone or PC that a hazardous chemical vehicle has been involved in a traffic accident, the solenoid valve of the pollution pool water inlet pipe 112 is opened, and the solenoid valve of the flocculation chamber water inlet pipe 142 is closed, so that the rainwater with the hazardous chemical leakage waste liquid enters the pollution pool 111 to be collected, and at the same time, the solenoid valve of the emptying pipe 124 is opened to quickly empty the original rainwater in the sedimentation tank 121; when the liquid level is detected by the liquid level gauge installed on the top of the pollution pool 111, the solenoid valve of the pollution pool water inlet pipe 112 and the solenoid valve of the pipe used for water discharge are closed, and at the same time, the solenoid valve of the flocculation chamber water inlet pipe 142 is opened to lead the hazardous chemical leakage waste liquid to the flocculation chamber 140 and the sedimentation tank 121, which will be pumped away for treatment by the management personnel afterwards.
