Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and in particular to an intelligent dosing flocculation system based on BIM. Background Art

[0002] The medicated flocculation process in water plants is mainly used to remove suspended matter, colloids, organic matter and other impurities in water and improve the quality of effluent water. Its working principle is to add flocculants to the water to be treated, and through the adsorption and bridging effect of the flocculants, the suspended particles and colloids in the water will flocculate and settle, and then the flocculants will be removed by filtration or sedimentation to achieve the purpose of purifying water quality.

[0003] BIM is the abbreviation of "Building Information Modeling", which is widely used in engineering design, construction, operation and maintenance. It can integrate the data and information of buildings, and has the characteristics of visualization, coordination, simulation, optimization, etc. Through the BIM display method, the location and parameter information of various equipment in the building can be obtained intuitively, in detail and completely.

[0004] The traditional dosing flocculation system basically adopts a simple adjustment mode based on the effluent water quality (turbidity), without considering the changes in other water quality information (turbidity, temperature, pH), resulting in strong lag and fluctuation in the adjustment, and lack of effective monitoring means for the formation of alum flocs during the dosing flocculation process. In addition, the traditional dosing system flocculation basically uses a two-dimensional plane or 2.5D display method in the system interface display, which can no longer meet the current mainstream demand for three-dimensional visualization.

[0030] like Figure 1The BIM-based intelligent dosing flocculation system shown uses a feedforward + feedback composite control method, including a flocculation sedimentation tank 5, which is connected to an inlet pipe 1, an outlet pipe 2 and a dosing pipe, and also includes a detector, a monitoring camera, a control terminal 7 and a display device.

[0031] An electromagnetic flowmeter is selected as the water inlet flowmeter, which is installed on the water inlet pipe 1 of the flocculation sedimentation tank 5. It is connected to the control terminal 7 by using a cable with the Modbus protocol, and the collected water inlet flow value is sent in real time as a feedforward signal, and the sending frequency is once every 10 seconds; a temperature sensor is selected and installed on the water inlet pipe 1 of the flocculation sedimentation tank 5. It is connected to the control terminal 7 by using a cable with the Modbus protocol and the collected water inlet temperature value is sent in real time as a feedforward signal, and the sending frequency is once every 10 seconds; a pH sensor is selected and installed in the flocculation sedimentation tank 5 On the water inlet pipe 1, a cable is used to connect with the control terminal 7 via the Modbus protocol and the collected water inlet pH value is sent in real time as a feedforward signal, and the sending frequency is once every 10 seconds; two turbidity sensors are selected as the water inlet turbidity sensor and the water outlet turbidity sensor, respectively, which are installed on the water inlet pipe 1 and the water outlet pipe 2 of the flocculation sedimentation tank 5, respectively, and a cable is used to connect with the control terminal 7 via the Modbus protocol and the collected water inlet turbidity value and water outlet turbidity value are sent in real time as a feedforward signal and a feedback signal, respectively, and the sending frequency is once every 10 seconds.

[0032] A Hikvision DS-2XC6244F-L series underwater camera is selected as a surveillance camera, which is installed at the bottom of the flocculation sedimentation tank 5. It is connected to the control terminal 7 through a network cable using the TCP / IP protocol to send the collected video surveillance information in real time as a feedback signal; the dosing pump 6 uses a variable frequency dosing pump 6, which is installed immediately outside the flocculation sedimentation tank 5. The polyaluminium chloride PAC in the pump is pumped into the tank through a dosing pipe that penetrates the tank wall. It is connected to the control terminal 7 using a cable and adopts the RS485 protocol. The dosing of the polyaluminium chloride PAC is completed by receiving the control signal sent from the control terminal 7, and the dosing frequency is once per minute.

[0033] The control terminal 7 is made of stainless steel and is internally configured with a Siemens S7-1500 PLC and corresponding power supply system and grounding system. The PLC uses cables to connect to the water inlet flow meter, water inlet turbidity sensor, temperature sensor, PH sensor, water outlet turbidity sensor, and dosing pump 6 respectively and uses the Modbus protocol. The PLC uses a network cable to connect to the video surveillance camera and uses the TCP / IP protocol.

The intelligent dosing flocculation system realizes intelligent control of the dosage according to the inlet flow, inlet turbidity, inlet temperature, inlet pH, and outlet turbidity through feedforward + feedback.
