Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an intelligent and efficient backwashing module for wastewater treatment systems. Background Technology

[0002] With the rapid development of the water treatment field, backwashing technology, as a core component for the stable operation of filtration systems in water treatment, directly impacts equipment energy consumption, maintenance costs, and filtration performance through its efficiency and level of intelligence. Traditional backwashing modules often employ fixed-sequence control or a single differential pressure triggering mechanism, which suffers from the following technical shortcomings:

[0003] (1) Low cleaning efficiency: The backwashing operation based on the preset cycle cannot dynamically adapt to changes in pollutant load, resulting in ineffective rinsing or incomplete cleaning, which accelerates the irreversible clogging of membrane modules / filter cartridges;

[0004] (2) Energy consumption and resource waste: Constant backwash intensity (such as flow rate and pressure parameters) causes excessive consumption of water and electricity resources under low pollution conditions, while in high pollution scenarios, it may require repeated backwashing due to insufficient cleaning power.

[0005] (3) Insufficient intelligence: Lack of multi-dimensional state perception of the backwashing process (such as turbidity gradient, pressure drop rate, flow attenuation coefficient, etc.), making it difficult to achieve closed-loop feedback optimization;

[0006] (4) Reliance on human experience: The operation and maintenance of the system rely heavily on human experience and lack intelligent operation and maintenance methods, resulting in high operation and maintenance costs and low efficiency;

[0007] (5) Difficulty in fault diagnosis: The lack of an effective fault diagnosis and early warning mechanism makes it difficult to quickly locate and eliminate faults, affecting the normal operation of the system. Utility Model Content

[0008] The purpose of this utility model is to solve the above-mentioned problems. This application proposes an intelligent and efficient backwashing module for sewage treatment systems, which effectively improves the automation and intelligence level of filtration systems, reduces operating costs, and improves production efficiency and product quality, and has broad application prospects.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an intelligent and efficient backwashing module for a wastewater treatment system, comprising a filter body, a pipeline system, a water backwashing system, an air backwashing system, a monitoring system, and a control system. The pipeline system includes an inlet pipe, a drain pipe, a backwashing inlet pipe, a backwashing drain pipe, an exhaust pipe, a vent pipe, and a backwashing air inlet pipe. The water backwashing system includes a backwashing water pump, which is located on one side of the filter body and connected to the filter body via the backwashing inlet pipe. The backwashing inlet pipe is equipped with a backwashing inlet valve. A backwashing drain pipe is located on the other side of the filter body, and a backwashing drain valve is installed on the backwashing drain pipe. The air backwashing system includes a backwashing blower, which is located on the same side as the backwashing water pump and connected to the filter body via the backwashing air inlet pipe. The backwashing air inlet pipe is equipped with a backwashing air inlet valve. A vent pipe is located on the other side of the filter body, and a vent valve is installed on the vent pipe.

[0010] Furthermore, the monitoring system includes a pressure transmitter, a turbidity meter, and an ultrasonic level gauge, all of which are installed inside the filter body and connected to the control system. The system transmits data to the control system, which is connected to the water backwash system, the air backwash system, the inlet valve, the drain valve, the vent valve, and the exhaust valve.

[0011] Furthermore, the backwash air inlet pipe is also equipped with an exhaust pipe, and the exhaust pipe is equipped with an exhaust valve.

[0012] Furthermore: an inlet pipe and a drain pipe are respectively provided on both sides of the filter body, an inlet valve is provided on the inlet pipe, and a drain valve is provided on the drain pipe.

[0013] Furthermore, the filter body adopts a double-cell design and is equipped with filter material inside. During backwashing, one cell is selected while the other cell operates normally.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a monitoring system, including a pressure transmitter, turbidity meter, and ultrasonic level gauge, which are installed inside the filter body and connected to the control system. This system enables real-time acquisition of system operation status data, with data acquisition accuracy improved by over 90% compared to traditional equipment. The acquired data is transmitted to the control system, which incorporates a specially designed controller and a deep learning chip. This controller utilizes machine learning algorithms to analyze and process the acquired data, record backwashing time, optimize backwashing intensity and time, and automatically optimize parameters such as backwashing intensity and frequency. While ensuring backwashing effectiveness, this system reduces energy consumption by 20-30%.

[0016] The modular design has a wide range of applications and can be used for various treatment scales, which can accelerate the project construction cycle and solve the problems of high dependence on manual labor and low degree of automation in traditional filtration systems. It also solves the problems of reliance on manual experience to adjust operating parameters (such as backwash pressure, flow rate, backwash cycle, etc.), resulting in slow response and large operating errors.

Detailed Implementation

[0020] To enable those skilled in the art to better understand and implement the technical solution of this utility model, the present utility model will be further described below with reference to specific embodiments. However, the embodiments described are only for illustration and are not intended to limit the present utility model.

[0021] like Figure 1 The diagram illustrates an intelligent and efficient backwashing module for a wastewater treatment system, comprising a filter body 1, a piping system 9, a water backwashing system, an air backwashing system, a monitoring system 10, a control system 11, and electric valves. The filter body 1 is the main carrier of this invention, employing a multi-compartment design with multiple compartments and internal filter material. During backwashing, one compartment is selected while the other operates normally. The piping system 9 includes an inlet pipe 901, a drain pipe 902, a backwashing inlet pipe 903, a backwashing drain pipe 904, an exhaust pipe 906, a vent pipe 907, and a backwashing air inlet pipe 905. The electric valves include an inlet valve 2, a drain valve 3, a vent valve 5, an exhaust valve 4, a backwashing inlet valve 6, a backwashing drain valve 7, and a backwashing air inlet valve 8, and are connected to the control system 11. The control system 11 is also connected to the water backwashing system and the air backwashing system.

[0022] The filter body 1 is provided with an inlet pipe 901 and an outlet pipe 902 on both sides. The inlet pipe 901 is provided with an inlet valve 2 to control the water inlet of the filter, and the outlet pipe 902 is provided with an outlet valve 3 to control the water outlet of the filter.

[0023] The water backwashing system includes a backwash water pump 12, which serves as the main power source for backwashing. The backwash water pump 12 performs restorative cleaning of the filter tank through control signals sent by the control system 11. The backwash water pump 12 is located on one side of the filter tank body 1 and is connected to the filter tank body 1 through a backwash water inlet pipe 903. The backwash water inlet pipe 903 is equipped with a backwash water inlet valve 6 to control the backwash water inlet. On the other side of the filter tank body 1, a backwash drain pipe 904 is provided, and a backwash drain valve 7 is provided on the backwash drain pipe 904 to control the backwash water outlet.

[0024] The air backwashing system includes a backwash blower 13, which serves as the main power source for water backwashing. The backwash blower 13 performs restorative cleaning of the filter tank through control signals sent by the control system 11. The backwash blower 13 and the backwash water pump 12 are located on the same side and are connected to the filter tank body 1 through a backwash air inlet pipe 905. The backwash air inlet pipe 905 is equipped with a backwash air inlet valve 8 to control the backwash air intake. The backwash air inlet pipe 905 is also equipped with an exhaust pipe 906, which is equipped with an exhaust valve 4 to discharge the air in the system after air backwashing. A vent pipe 907 is provided on the outer side of the other side of the filter tank body 1, and a vent valve 5 is provided on the vent pipe 907 to control the venting of the filter tank during maintenance.

[0025] The monitoring system 10 includes a pressure transmitter, a turbidity meter, and an ultrasonic level gauge for monitoring equipment operating parameters. It is installed inside the filter body 1 and connected to the control system 11, transmitting data to the control system 11. The control system 11 is the nerve center of the intelligent and efficient backwashing module, with an embedded processor and deep learning chip. Through preset programs and deep learning, it analyzes and processes the monitoring data received by the monitoring system. The control system 11 is connected to the water backwashing system, the air backwashing system, the inlet valve 2, the drain valve 3, the vent valve 5, and the exhaust valve 4 to adjust and control the equipment and valves in the system, thereby ensuring the normal operation of the entire system.

[0026] The control logic of the control system is as follows:

[0027] When the filter body 1 is under normal conditions, the inlet valve 2 and the drain valve 3 are in the open state, while the backwash inlet valve 6, the backwash drain valve 7, the backwash air inlet valve 8, the exhaust valve 4, and the vent valve 5 are in the closed state.

[0028] When the filter body 1 is about to be backwashed, the inlet valve 2 and the drain valve 3 are closed, the backwash drain valve 7 is opened first, and then the backwash water pump 12 is opened, with an interval of 10 seconds.

[0029] Turn on the backwash fan 13, and after the backwash fan 13 is running smoothly, open the backwash air inlet valve 8.

[0030] First, rinse separately with air for 300 seconds (the time can be increased or decreased depending on the specific situation);

[0031] Open the backwash inlet valve 6, and after a 5-second interval, start the backwash water pump 12. Mix air and water for 300 seconds (time adjustable).

[0032] Turn off the backwash fan 13 and the backwash air inlet valve 8;

[0033] Rinse with water alone for about 300 seconds (time adjustable);

[0034] Turn off backwash water pump 12;

[0035] Close the backwash inlet valve 6;

[0036] Open exhaust valve 4;

[0037] 4. Close the exhaust valve.

[0038] Wastewater from the previous treatment unit enters the filter body through the inlet pipe. After filtration, the wastewater flows out through the outlet pipe and enters the next treatment unit. After the filter has been running for a period of time, its filtration capacity decreases due to contaminant blockage, requiring backwashing. The filter is controlled by a time-based system with a 48-hour backwash cycle, but this can be automatically adjusted based on effluent quality, head loss, etc. Backwashing is initiated when the filter water level rises and the filtration rate decreases.

[0039] This invention solves the problem of low automation in traditional filtration systems, which rely on manual experience to adjust operating parameters (such as backwash pressure, flow rate, and backwash cycle), resulting in slow response and large operational errors. In contrast, a new intelligent and efficient backwash module is adopted, which monitors the operating status in real time through multiple parameter sensors (pressure transmitter, turbidity meter, level gauge, etc.) to achieve dynamic perception of the operating status. The intelligent control system based on machine learning algorithms automatically optimizes parameters such as backwash intensity and backwash frequency, reducing manual intervention by more than 90%.
