Description

Technical Field

[0001] This invention relates to the field of water plant process operation control technology, and in particular to a method and system for disinfection control of multi-compartment post-carbon filter. Background Technology

[0002] For post-activated carbon filters, the risk of biological leakage is extremely high under certain conditions. Therefore, activated carbon filters need to be backwashed with chlorinated backwash water periodically, and microorganisms breeding in the lower part of the filter bed should be disinfected and disinfected using a blister pack.

[0003] The current standard backwashing procedure is as follows: Since the triggering conditions for backwashing cannot be automatically measured, in order to ensure that no biological leakage occurs, the disinfection process of the activated carbon filter is generally carried out simultaneously with the backwashing of the activated carbon filter, with backwashing once at a fixed time interval. Chlorine is added to the backwash water for backwashing. This will lead to excessive consumption of chemicals. At the same time, the removal of pollutants by the biological activated carbon filter depends on functions such as filtration, adsorption and biodegradation. Improper use of disinfectants will have a negative impact on the biodegradation function and reduce the removal efficiency of the activated carbon filter.

[0004] Because the existing carbon filters are all disinfected as a whole, in emergency situations, such as excessive proliferation of microorganisms in summer clogging the filter's main outlet pipe and causing the filter to overflow, or when it is visually observed that there are too many zooplankton in the filter, the entire production line will be shut down for emergency disinfection and bubble tank disinfection of all carbon filters. There is no targeted disinfection of any specific carbon filter, which leads to the water plant shutting down and causes a significant impact. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide a method and system for disinfection and control of multi-compartment post-carbon filter to overcome or at least partially solve the above problems.

[0023] The activated carbon filter includes multiple independently divided carbon filter bodies;

[0024] The sampling pump is used to collect water samples corresponding to each compartment of the activated carbon filter.

[0025] The zooplankton online monitoring device is used to enrich zooplankton in water samples from each carbon filter compartment to obtain enriched samples. The enriched samples are then automatically prepared onto slides and observed and imaged under a microscope to obtain images. Image analysis technology is used to identify and analyze the images to obtain zooplankton data corresponding to the water samples. The zooplankton data includes the types of zooplankton and the corresponding content of each type. The cumulative amount of zooplankton is calculated based on the zooplankton data and the unit water collection volume, and the assessment level of the cumulative amount of zooplankton is determined.

It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of the present invention, rather than limitations on the technical solutions of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0043] This invention provides a method for disinfection and control of multi-compartment post-carbon filter beds. Figure 1 This is a schematic flowchart of a multi-compartment post-carbon filter disinfection and control method provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the disinfection and control method for this multi-compartment post-carbon filter includes the following steps:

[0044] S1. Sampling and obtaining water samples corresponding to each cell of the activated carbon filter;

[0045] In this embodiment of the invention, the activated carbon filter includes multiple independently divided carbon filter bodies, each of which operates independently. The number of carbon filter bodies in the activated carbon filter is selected according to actual needs. For example, in this embodiment of the invention, the number of carbon filter bodies is 8. In other embodiments of the invention, the number of carbon filter bodies can also be set to 6, 10, etc., depending on different application scenarios. This embodiment of the invention does not limit this.

[0046] The water sample can be collected by a sampling pump or a water intake device with the same function. Each time, water samples are collected from each section of the carbon filter tank. For example, considering that the volume of each carbon filter tank may be different, the power of the sampling pump may be different, etc., the actual amount of water sample collected will not be exactly the same. The amount of water sample collected can be determined according to the actual application requirements. In this embodiment of the invention, the water sample collected is 25L.

[0047] It should be noted that since the water samples from each carbon filter cell are collected separately, the same sampling pump can be used to connect different pipelines to collect the water samples from each carbon filter cell. In some application scenarios, a sampling pump can also be assigned to each carbon filter cell to collect the water samples.

[0048] S2. The water samples from each carbon filter cell were subjected to zooplankton enrichment treatment to obtain enriched samples.

[0049] S3. The enriched sample is automatically prepared onto a glass slide and observed and imaged under a microscope to obtain the image.

[0050] S4. The image is identified and analyzed using image analysis technology to obtain zooplankton data corresponding to the water sample. The zooplankton data includes the types of zooplankton and the content of each type of zooplankton.

[0051] S5. Calculate the cumulative amount of zooplankton based on the zooplankton data and the unit water collection volume, and determine the assessment level of the cumulative amount of zooplankton.

[0052] In this embodiment of the invention, a zooplankton online monitoring device is used to enrich zooplankton in water samples from each section of a carbon filter, resulting in enriched samples. These enriched samples are then automatically prepared onto slides and observed under a microscope to obtain images. Image analysis technology is used to identify and analyze these images to obtain zooplankton data corresponding to the water samples. This zooplankton data includes the types of zooplankton and the corresponding content of each type. Based on the zooplankton data and the unit water collection volume, the cumulative zooplankton amount is calculated, and the assessment level of the cumulative zooplankton amount is determined.

[0053] Furthermore, before determining the assessment level of the accumulated zooplankton, this embodiment of the invention sets the assessment level of the accumulated zooplankton through an online zooplankton monitoring device, as well as the alarm level and disinfection level corresponding to each assessment level.

[0054] The system also determines an alarm level based on the assessment level of the zooplankton accumulation using the disinfection control component, and determines a disinfection level based on the assessment level of the zooplankton accumulation.

[0055] In this embodiment of the invention, the accumulated amount of zooplankton is calculated using the following formula:

[0056] Q i = ∑q i ×t i

[0057] In the formula, Q i q represents the cumulative zooplankton content within the i-th carbon filter cell, expressed in cells / 100 liters; i t represents the zooplankton content in the i-th carbon filter cell during each water collection period. i The unit water collection volume within the i-th carbon filter cell during each water collection period.

[0058] In this embodiment of the invention, an alarm level is determined based on the assessment level of the zooplankton accumulation by a pest control component, and a pest control level is determined based on the assessment level of the zooplankton accumulation, wherein the pest control level is used to characterize the pest control operation performed and the corresponding chlorine dosage.

[0059] S6. Determine the alarm level based on the assessment level of the zooplankton accumulation and provide alarm information, and determine the disinfection level based on the assessment level of the zooplankton accumulation and perform disinfection operations.

[0060] For example, the assessment level of zooplankton accumulation may include a normal stage and an emergency stage; wherein, when the assessment level of zooplankton accumulation is a normal stage, the corresponding alarm level is a normal alarm and the corresponding disinfection level is backwash disinfection; when the assessment level of zooplankton accumulation is an emergency stage, the corresponding alarm level is an emergency alarm and the corresponding disinfection level is soaking pond disinfection.

[0061] The backwashing disinfection involves gas backwashing, gas-water backwashing, and chlorination backwashing of the backwash water to the individual carbon filter cells.

[0062] The disinfection process involves disinfecting the individual carbon filter cells with a chlorine-containing solution followed by backwashing with water.

[0063] Specifically, in Q i When the zooplankton accumulation is <80 individuals / 100 liters, the assessment level is considered to be in the normal stage, at which point backwashing and disinfection should be carried out; in Q... i When the number of zooplankton accumulation is ≥80 per 100 liters, the assessment level is considered to be in the emergency stage, at which point pond disinfection should be carried out.

[0064] To further improve the control precision of pest control, this embodiment of the invention, when the assessment level of zooplankton accumulation is at the normal stage, performs further classification control based on the zooplankton accumulation, for example:

[0065] In 70≤Q i When the concentration is less than 80 per 100 liters, the chlorine dosage during backflushing disinfection is 300 × 1.8 L / h.

[0066] In 60≤Q i When the concentration is less than 70 per 100 liters, the chlorine dosage during backflushing disinfection is 300 × 1.5 L / h.

[0067] In 50≤Q i When the number of insects per 100 liters is less than 60, the dosage of chlorine added during backflushing disinfection is 300 × 1.2 L / h.

[0068] Of course, in some application scenarios, maintenance disinfection may also be performed on the activated carbon filter. In this embodiment of the invention, a basic chlorination dosage of 300 L / h can be used for disinfection.

[0069] On the other hand, when the assessment level of the accumulated zooplankton is in the emergency stage, the required dosage of chlorine for disinfection of the pond will be lower. In this case, the chlorine dosage corresponding to the embodiment of the present invention is 300 × 1.2 L / h.

[0070] In this embodiment of the invention, the determination result of the disinfection control component is input into a PLC, and the PLC provides feedback alarm information and transmits control commands for the disinfection operation. The system also includes an air flushing pump, a dosing pump, a water flushing pump, a sand filter, an ozone contact tank, and a clear water tank. The air flushing pump is connected to the PLC and the activated carbon filter, the dosing pump is connected to the PLC and the activated carbon filter, and the water flushing pump is connected to the PLC and the activated carbon filter. Air flushing valves, dosing valves, and water flushing valves are respectively installed on the connecting pipelines of the air flushing pump, dosing pump, and water flushing pump to the activated carbon filter to control the flow rate. The ozone contact tank is connected to the sand filter and the activated carbon filter, and the clear water tank is connected to the activated carbon filter and the water flushing pump.

[0071] During backwashing disinfection, the PLC controls the opening of the air flushing pump, water flushing pump, and dosing pump, and specifically controls the opening of the air flushing valve, dosing valve, and water flushing valve connected to the carbon filter body. The three-stage air-water combined chlorination backwashing consists of air flushing for 3 minutes, air-water backwashing for 5 minutes, and chlorinated water backwashing for 10 minutes. The amount of chlorine added is based on the dosage corresponding to the assessment level of the zooplankton accumulation.

[0072] During the disinfection of the filter tank, an emergency disinfection treatment of the chlorine-containing filter tank in a single filter tank is carried out. The PLC controls the start of the water flushing pump and the dosing pump, and specifically controls the opening of the water flushing valve and the dosing valve of a certain alarm filter tank. The emergency disinfection treatment of the chlorine-containing filter tank in a single filter tank involves disinfecting the filter tank with chlorine-containing water for 3 hours.

[0073] Once the predetermined disinfection time has been reached, the disinfection of that carbon filter cell can be considered complete, and the disinfection of that carbon filter cell will be re-sampled and recalculated.

[0074] In this embodiment of the invention, since the water samples from each carbon filter compartment are collected separately, the same air pump can be connected to different pipelines to aerate and flush each compartment. In some application scenarios, an air pump can be assigned to each carbon filter compartment for aeration and flushing. The air pump can also be connected to a blower to provide a power source.

[0075] Similarly, in this embodiment of the invention, chlorination can be performed on each compartment of the carbon filter by connecting the same dosing pump to different pipelines. In some application scenarios, a separate dosing pump can be assigned to each compartment of the carbon filter for chlorination. The dosing pump can be connected to a storage tank for storing the chlorine to be added.

[0076] Furthermore, the same water pump can be connected to different pipelines to backwash each carbon filter cell. In some application scenarios, each carbon filter cell can also be assigned a water pump to achieve backwashing.

[0077] The multi-compartment post-carbon filter disinfection and control method described in this invention has the following advantages compared to the prior art:

[0078] 1. Sampling and disinfection control are carried out separately for each cell of the activated carbon filter. Compared with the existing overall disinfection, the operation is more flexible, does not require a complete shutdown, and reduces the negative impact of disinfection.

[0079] 2. By analyzing water samples and assessing the zooplankton accumulation level in each section of the carbon filter, an alarm level is determined and alarm information is fed back based on the zooplankton accumulation level, and a disinfection level is determined and disinfection operations are performed based on the zooplankton accumulation level. This allows for precise control of the dosage of chemicals, aeration, or backwashing in each section of the carbon filter, reducing the amount of chemicals used, lowering costs, overcoming the problem of excessive chemical consumption, and avoiding negative impacts on zooplankton degradation.

The enriched samples are then automatically prepared with glass slides and observed and imaged under a microscope to obtain images. The images are then analyzed using image analysis technology to obtain zooplankton data corresponding to the water samples. The zooplankton data includes the types of zooplankton and the content of each type. The cumulative amount of zooplankton is calculated based on the zooplankton data and the unit water collection volume, and the assessment level of the cumulative amount of zooplankton is determined.
