Description

Technical Field

[0001] This invention relates to the design of water and wastewater treatment processes, and more specifically, to a water and wastewater treatment process optimization and automatic design system and a design method using the system, which can optimize the water and wastewater treatment process of water and wastewater treatment equipment including multiple treatment processes and automatically design the optimized water and wastewater treatment process. Background Technology

[0002] In South Korea, due to environmental pollution caused by advanced industrial development since the 1950s, population growth, and improved living standards, pollutant emissions have increased, leading to increasingly severe water pollution.

[0003] Specifically, the following problems exist: an increasing number of rivers adjacent to water source protection areas, rural rivers that receive non-point source pollutants such as livestock and poultry wastewater and fertilizers, and urban rivers that receive domestic and industrial wastewater are losing their value as water resources due to water pollution.

[0004] This pollution in small rivers or upstream tributaries in urban areas is directly related to the pollution of larger rivers. Furthermore, it is considered very serious because if the pollution of rivers around our homes continues, it can cause direct and indirect harm, such as sanitation problems including odor, fish deaths, and groundwater contamination.

[0005] In recent years, due to population growth, industrialization, and urbanization, water sources, rivers, and groundwater have become increasingly polluted, making it crucial to ensure the safety of drinking water. Therefore, research has been actively conducted on water purification or water and wastewater treatment equipment to meet the demand for clean and safe drinking water.

[0006] Existing water and wastewater treatment equipment removes pollutants through complex internal mechanisms and is non-linear.

[0007] Therefore, depending on the water and wastewater treatment plant, the following information is typically used to design water and wastewater treatment equipment: project specifications for water purification or wastewater treatment, basic information about the target equipment for water purification or wastewater treatment (based on the presence or absence of disinfection facilities, process sequence, coagulant injection, etc.), information about the wastewater flowing into the water purification or wastewater treatment equipment, and information about the target water quality of the water purification or wastewater treatment equipment.

[0008] Incidentally, the construction of water and wastewater treatment facilities is carried out based on the design scheme, which includes treatment quality balance, treatment design calculations, design drawings, and detailed construction cost information, and is carried out under the aforementioned predetermined design conditions.

[0009] Here, the design scheme for water and wastewater treatment equipment includes treatment quality balance, treatment design calculations, design drawings, and detailed construction cost information, all of which are generated using separate software, rather than all of them being generated using a single software. The generated information is then entered manually.

[0010] However, as mentioned above, since the optimal process design scheme for water and wastewater treatment equipment is done manually, there is a problem that a lot of time is required to prepare the design scheme.

[0011] Specifically, the design scheme should be completed in a short period of time with limited manpower.

[0012] During the design preparation process, frequent iterative revisions are required due to design changes, quality balancing / drawing reviews, and delays in preparing guidelines and Q&As. This results in increased time and costs associated with preparing the design proposal.

[0013] Therefore, the applicant has put forward this invention to solve the above problems, and the related technology of this invention includes Korean Patent Registration No. 10-1690211 (Invention title: BIM-based construction value engineering (VE) processing system, registration date: December 21, 2016). Summary of the Invention

[0042] In the following description, embodiments of the invention will be illustrated with reference to the accompanying drawings to allow those skilled in the art to readily implement these embodiments. The invention can be embodied in various forms and is not limited to the embodiments described herein.

[0043] Note that the accompanying drawings are schematic and not to scale. For clarity and convenience in referring to the drawings, the relative dimensions and scales of the parts shown have been enlarged or reduced, and any dimensions are illustrative rather than limiting. Furthermore, the same reference numerals are used to indicate the same structures, elements, or parts shown in two or more drawings to indicate similar features.

[0044] The embodiments of the present invention specifically illustrate preferred embodiments of the invention. As a result, various modifications to the drawings are possible. Therefore, the embodiments are not limited to the specific shapes shown in the drawings, and may also include, for example, modifications to the shapes formed by manufacturing.

[0045] Hereinafter, a water and wastewater treatment process optimization and automatic design system 10 and a design method S100 using the system according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0046] First, refer to Figure 1 and Figure 2 To describe the water and wastewater treatment process optimization and automatic design system 10 (hereinafter referred to as the "automatic design system").

[0047] like Figure 1 As shown, the automatic design system 10 according to an embodiment of the present invention includes a water and wastewater treatment process simulation unit 110, a construction cost calculation unit 120, and an output unit 130.

[0048] First, according to an embodiment of the present invention, the automatic design system 10 is used to design the process configuration 20 of water and wastewater treatment equipment that matches the daily treatment capacity and target water quality.

[0049] Typically, water and wastewater treatment equipment includes a variety of treatment processes for treating wastewater.

[0050] For example, water and wastewater treatment equipment may include a combination of various treatment processes, such as pretreatment facility processes, main treatment facility processes, tertiary treatment facility processes, disinfection facility processes, and auxiliary facility processes. Here, a treatment module corresponding to each treatment process is included to perform each treatment process, and a single process configuration 20 is derived by combining multiple treatment modules.

[0051] The water and wastewater treatment process simulation unit 110 derives one or more process configurations 20 by combining multiple treatment modules based on basic design information including target water quality and the daily treatment capacity to be achieved.

[0052] In addition, the water and wastewater treatment process simulation unit 110 generates a mass balance and design calculation based on the obtained process configuration 20, and performs a simulation according to the design calculation to produce the expected effluent water quality (output).

[0053] Here, the volume of water flowing into the water and wastewater treatment equipment is referred to as capacity.

[0054] In addition, design calculations refer to the billing type used to calculate what type of process configuration should be configured for the capacity of the influent and wastewater treatment equipment.

[0055] like Figure 2 (a) and Figure 2 As shown in (b), the process configuration 20 of the water and wastewater treatment equipment may include a first treatment module 21 configured to perform a pretreatment facility process and a second treatment module 23 configured to perform a main treatment facility process.

[0056] In addition, the process configuration 20 of the water and wastewater treatment equipment may include a third treatment module 25 configured to perform a tertiary treatment facility process, a fourth treatment module 27 configured to perform a disinfection facility process, and a fifth treatment module 29 configured to perform an auxiliary facility process.

[0057] like Figure 2 As shown in (a), the process configuration 20 of the water and wastewater treatment equipment has a first treatment module 21, a second treatment module 23, a third treatment module 25 and a fourth treatment module 27 arranged in this order.

[0058] In addition, the process configuration 20 of the water and wastewater treatment equipment can also be designed to operate the fifth treatment module 29 based on the treatment results of the third treatment module 25.

[0059] like Figure 2 As shown in (b), the process configuration 20 of the water and wastewater treatment equipment can also be designed to operate the first treatment module 21, the second treatment module 23, the third treatment module 25, the fourth treatment module 27 and the fifth treatment module 29 in this order.

[0060] For reference only. Figure 2 (a) and Figure 2 (b) Examples of process configurations 20 for water and wastewater treatment equipment are shown respectively, and the invention is not necessarily limited thereto.

[0061] In such Figure 2 (a) and Figure 2In the process configuration 20 derived in (b), the resulting treatment capacity Q' and the expected effluent quality S' can vary based on the input inflow capacity Q and the target water quality S.

[0062] Process configuration 20 can also be redesigned by adjusting the treatment capacity Q' and the expected effluent quality S'. Here, economic feasibility can be reviewed based on the treatment capacity Q' and expected effluent quality S' generated by process configuration 20, and process configuration 20 can be redesigned based on the results.

[0063] The process configuration 20 for water and wastewater treatment equipment is derived by repeatedly executing the above process, and the optimal treatment process is selected based on the derived process configuration 20.

[0064] Therefore, multiple process configurations 20 based on combinations of multiple processing modules 21, 23, 25, 27 and 29 are stored in the water and wastewater treatment process simulation unit 110.

[0065] In addition, the water and wastewater treatment process simulation unit 110 generates structural dimensions for each treatment module constituting the process configuration 20 based on detailed design information.

[0066] Here, the detailed design information input into the water and wastewater treatment process simulation unit 110 may include detailed information about the inflowing wastewater and at least one of the main design factors, retention time, and target water quality corresponding to the generated process configuration 20.

[0067] The detailed information of the inflowing wastewater input into the detailed design information refers to information related to the detailed characteristics of the wastewater, which is used for accurate simulation in the water and wastewater treatment process simulation unit 110.

[0068] For reference, information related to the characteristics of wastewater can be directly input by the designer of the water and wastewater treatment equipment, or the database analysis data or information stored in the data storage section described below can be used as information related to the characteristics of wastewater.

[0069] In addition, the main design factors input into the detailed design information refer to information related to design factors associated with the determined optimal process configuration.

[0070] Here, the detailed structural dimensions generated from the main design factors of the input to the detailed design information can be automatically generated using structural dimensions that take into account residence time and target water quality.

[0071] Meanwhile, the automatic design system 10 includes a process drawing unit 112, which is configured to export multiple process configurations 20 stored in the water and wastewater treatment process simulation unit 110.

[0072] The process drawing unit 112 derives one or more process configurations 20 suitable for basic design information from multiple process configurations 20 stored in the water and wastewater treatment process simulation unit 110.

[0073] Here, the basic design information for deriving a suitable process configuration 20 by inputting through the process drawing unit 112 may include information related to the following: information about the project to be designed, basic information about the water and wastewater treatment equipment, information related to the inflow water and wastewater treatment equipment, and information related to the target water quality.

[0074] For example, project information could be for water and wastewater treatment equipment, including the project name, region (country), and customer information for the water and wastewater treatment equipment to be designed.

[0075] In addition, basic information about water and wastewater treatment equipment may include information related to the presence or absence of disinfection facilities and the preferred disinfection process, the presence or absence of process sequence and the number of sequences, and whether coagulant is injected and the preferred coagulant.

[0076] In addition, information related to the inflow water and wastewater treatment equipment may include information about the following: characteristics of the inflow wastewater or default values ​​for each country, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH3N), reference water temperature (average, maximum, minimum), average daily wastewater volume, wastewater volume per unit time, and maximum wastewater volume per hour.

[0077] Here, the information about the target water quality can be based on the target water quality according to national regulatory water quality guidelines.

[0078] Here, the designer of the water and wastewater treatment equipment can select a suitable process configuration 20 from the process configuration 20 derived from the water and wastewater treatment process simulation unit 110. For reference, a system or program, such as a separately provided computer, can be used to select a suitable process configuration 20 from the water and wastewater treatment process simulation unit 110.

[0079] For example, when the designer is involved in selecting the appropriate process configuration 20 for each processing procedure, one or more process configurations 20 derived from the process drawing unit 112 can be compared / listed to select the appropriate process configuration 20.

[0080] The criteria for comparison or selection of process configuration 20 may include water quality, construction cost, required area, maintenance and management costs, etc. for each process configuration 20.

[0081] Conversely, if the designer is not involved in selecting the appropriate process configuration 20 for each process, the appropriate process configuration 20 can be selected by updating each process configuration 20, the average design constant value of the basic process configuration 20, or by collecting / analyzing field data through key design factors.

[0082] Meanwhile, the water and wastewater treatment process simulation unit 110 performs dynamic simulation based on the judgment conditions and outputs the final mass balance and design calculation as its result.

[0083] Here, the water and wastewater treatment process simulation unit 110 can also perform simulations based on the generated structural dimensions, taking into account judgment conditions other than basic design information, in order to review the stability of the derived process configuration 20.

[0084] Here, when using the water and wastewater treatment process simulation unit 110 to review the stability of the derived process configuration 20, the simulation is performed considering judgment conditions such as changes in the amount of high concentration, low concentration, low water temperature, low flow rate, and high flow rate, in addition to the basic design information.

[0085] For example, the judgment conditions input to the water and wastewater treatment process simulation unit 110 may include changes in water temperature conditions to determine whether the target water quality is met when the water temperature changes in winter and summer, and changes in the concentration conditions of the inflowing wastewater to determine whether the target water quality is met when the wastewater flows in at high and low concentrations.

[0086] Furthermore, the judgment conditions input to the water and wastewater treatment process simulation unit 110 may include changes in the flow rate of the inflowing wastewater, used to determine whether the target water quality is met when the wastewater flows in at high or low flow rates. It may also include water quality pattern analysis when the inflow conditions (flow rate, concentration) change daily / weekday / weekend and water quality pattern analysis when the inflow conditions (flow rate, concentration, water temperature) change seasonally / annually to determine whether the target water quality is met.

[0087] In other words, the judgment conditions input into the water and wastewater treatment process simulation unit 110 may include at least one of the above conditions.

[0088] Simultaneously, design drawings based on process configuration 20 are generated based on design calculations generated by the water and wastewater treatment process simulation unit 110. In other words, the design drawings generated using the water and wastewater treatment process simulation unit 110 involve the processing modules according to each process configuration 20 and are generated by the drawing generation unit 122.

[0089] Here, the design drawings generated by the drawing generation unit 122 may be facility layout diagrams, processing system diagrams, equipment lists, piping and instrumentation diagrams (P&ID), machine layout diagrams, overall structure diagrams, monitoring and control system configuration diagrams, distribution panel wiring diagrams, information flow diagrams (IFD), electrical equipment diagrams, maintenance system diagrams, etc., but are not necessarily limited to these.

[0090] Here, the drawing generation department 122 generates a preliminary product.

[0091] Then, the drawing generation unit 122 generates secondary products based on the generated primary products, thus preventing design errors that may occur in the prior art for water and wastewater treatment equipment.

[0092] For reference, the detailed values ​​of the design drawing generated by the drawing generation unit 122 are generated based on the exported process configuration 20.

[0093] At the same time, the construction cost can be calculated based on the design calculations generated by the water and wastewater treatment process simulation unit 110.

[0094] Here, the calculated construction cost is based on the design drawings generated by the drawing generation unit 122 and is generated by the construction cost calculation unit 120.

[0095] The construction costs generated by the Construction Cost Calculation Department 120 may include the following items: maintenance costs, construction costs and maintenance management fees, civil engineering costs, mechanical construction costs, electrical / surveying construction costs, testing and operation costs, building construction costs, calculation of annual maintenance and management fees, total life cycle cost (LCC), etc.

[0096] In addition, 20 outputs can be configured for each exported process, with estimated effluent quality and construction costs.

[0097] Here, the output unit 130 outputs the expected outflow water quality and construction cost corresponding to each process configuration 20.

[0098] Specifically, the output unit 130 provides the design calculations, expected outflow water quality, and construction costs of the entire process configuration 20 that meet the target water quality.

[0099] In addition, an output unit 130 can be provided to output multiple process configurations 20 and output design calculations, expected effluent quality and construction costs for each process configuration 20.

[0100] Meanwhile, if process configuration 20 is determined in output unit 130 to not meet the target water quality, water and wastewater treatment process simulation unit 110 derives one or more process configurations 20 again based on basic design information. Then, water and wastewater treatment process simulation unit 110 generates design calculations based on the derived process configurations 20, and generates the expected effluent water quality again based on the design calculations.

[0101] Here, the output unit 130 allows the water and wastewater treatment process simulation unit 110 to perform the simulation again using analysis / learning techniques.

[0102] In this way, at least one of the following conditions can be adjusted: target water quality, structural dimensions, equipment dimensions, and process configuration 20.

[0103] Meanwhile, the automatic design system 10 according to an embodiment of the present invention also includes a scheme generation unit 140.

[0104] The scheme generation unit 140 is used to generate design schemes for the process design of water and wastewater treatment equipment. In other words, the scheme generation unit 140 generates design schemes that include at least one of the following: design calculations generated by the water and wastewater treatment process simulation unit 110, design drawings generated by the drawing generation unit 122, and construction costs output by the output unit 130.

[0105] Furthermore, the automatic design system 10 according to an embodiment of the present invention also includes a data storage unit 150.

[0106] Data storage unit 150 can store information for process design of water and wastewater treatment equipment in the form of big data or cloud.

[0107] Specifically, the data storage unit 150 may be linked to at least one of the following: process drawing unit 112, water and wastewater treatment process simulation unit 110, drawing generation unit 122, construction cost calculation unit 120, output unit 130, and scheme generation unit 140.

[0108] Therefore, the information required by each department can be provided in a timely manner through the data storage unit 150.

[0109] Here, the data storage unit 150 can store one or more process configurations 20, which are suitable for basic design information and are exported by the process drawing unit 112.

[0110] In addition, the data storage unit 150 can store one or more process configurations 20 based on the combination of multiple processing modules generated by the water and wastewater treatment process simulation unit 110, as well as the expected outflow water quality based on the process configuration 20, according to quality balance and design calculations.

[0111] In addition, the data storage unit 150 can store the design drawings of the process configuration 20 generated by the drawing generation unit 122 and the construction costs calculated by the construction cost calculation unit 120.

[0112] In addition, the data storage unit 150 may include the output unit 130, which outputs the expected outflow water quality and construction cost for each process configuration 20.

[0113] In addition, the data storage unit 150 can store design schemes, including design calculations, design drawings, expected outflow water quality, or construction costs generated by the scheme generation unit 140.

[0114] For reference, the information stored in the data storage unit 150 is not limited to those mentioned above, and as stated above, any information for the optimal process design of water and wastewater treatment equipment can be stored in the data storage unit 150.

[0115] The following will refer to Figures 1 to 4 The design method S100 (hereinafter referred to as the "automation method") using the water and wastewater treatment process optimization and automatic design system of the present invention is described.

[0116] The design method S100 includes simulation execution operation S120, construction cost calculation operation S140, and output operation of expected outflow water quality and construction cost S150.

[0117] First, the simulation execution operation S120 includes performing a simulation to generate mass balance and design calculations.

[0118] In other words, the simulated execution operation S120 includes generating one or more process configurations 20 and structural dimensions based on basic design information, which includes the treatment capacity and target water quality of the water and wastewater treatment equipment, through the combination of multiple processing modules.

[0119] In addition, the simulation execution operation S120 includes performing simulations based on the generated process configuration 20 to produce quality balance and design calculations.

[0120] The simulation execution operation S120 is performed by the water and wastewater treatment process simulation unit 110 of the automatic design system 10.

[0121] Meanwhile, in the design method S100 according to an embodiment of the present invention, before performing the simulation execution operation S120, the process configuration and dimension output operation S110 is performed.

[0122] The process configuration and dimension output operation S110 includes exporting one or more process configurations 20 and structural dimensions suitable for basic design information.

[0123] The basic design information entered in the process configuration and dimension output operation S110 includes basic information about the water and wastewater treatment equipment, information related to the wastewater flowing into the water and wastewater treatment equipment, and information related to the target water quality.

[0124] Meanwhile, the selection of process configuration 20 in the process configuration and dimension output operation S110 can also be performed by the designer of the water and wastewater treatment equipment. For reference, the selection of process configuration 20 can also be performed using a system or program such as a separate computer in the process configuration and dimension output operation S110.

[0125] In the process configuration and dimension output operation S110, judgment conditions are compared or listed to select the appropriate process configuration 20.

[0126] For reference, the criteria for comparison or listing may be conditions such as water quality, construction cost, required area, maintenance and management costs for each process configuration 20, but are not necessarily limited to these.

[0127] The process configuration and dimension output operations S110 are performed by the process drawing unit 112 of the automatic design system 10.

[0128] Meanwhile, for ease of description, the process configuration and dimension output operation S110 and the simulation execution operation S120 have been described separately.

[0129] However, preferably, the process configuration and dimension output operation S110 and the simulation execution operation S120 can be performed essentially in a single operation.

[0130] The process configuration and dimension output operation S110 and the simulation execution operation S120 will be defined as simulation execution operation S120, and refer to... Figure 4 Provide a detailed description.

[0131] First, in the simulation execution operation S120, basic design information is input (S121). Here, basic design information includes information such as treatment capacity and design water quality.

[0132] Then, based on the combination of multiple processing modules, one or more (preferably multiple) combinations of process configurations 20 are proposed (S122). Here, a review of the proposed combinations of process configurations 20 may also be performed.

[0133] Then, structural dimensions suitable for the corresponding process configuration 20 are generated (S123).

[0134] Then, a simulation is performed based on the generated structure dimensions (S124).

[0135] In other words, dynamic simulations are performed based on the generated structural dimensions, taking into account variations in quantities or conditions such as high concentration, low concentration, low water temperature, low flow rate, and high flow rate, in addition to basic design information.

[0136] For reference, the stability of the proposed process configuration 20 can also be reviewed during the dynamic simulation.

[0137] Then, the final mass balance and design calculations are generated based on the results of the simulation (S125).

[0138] The above-mentioned simulation execution operation S120 is performed by the water and wastewater treatment process simulation unit 110 of the automatic design system 10.

[0139] Following the process configuration and dimension output operation S110, the water and wastewater treatment process simulation execution operation S120 is performed.

[0140] Then, after the simulation operation S120, the drawing generation operation S130 is executed.

[0141] The drawing generation operation S130 includes generating a design drawing of the processing module based on the mass balance and design calculations generated in the simulation execution operation S120, according to the process configuration 20.

[0142] The drawing generation operation S130 mainly includes generating the design drawing of the processing module based on the process configuration 20.

[0143] In addition, the drawing generation operation S130 includes generating detailed design drawings based on the initially generated design drawings.

[0144] Therefore, in the drawing generation operation S130, values ​​for the detailed design drawing of the process configuration 20 and the design drawing of the processing module according to the process configuration 20 are generated.

[0145] The drawing generation operation S130 is performed by the drawing generation unit 122 of the automatic design system 10.

[0146] Then, after generating the design drawing of process configuration 20 through drawing generation operation S130, construction cost calculation operation S140 is performed.

[0147] Construction cost calculation operation S140 includes calculating construction costs based on design calculations. In this case, the calculated construction cost is based on the design drawings generated in the drawing generation operation S130.

[0148] The construction cost calculation operation S140 is performed by the construction cost calculation unit 120 of the automatic design system 10.

[0149] Here, the construction costs calculated in the construction cost calculation operation S140 may include maintenance costs, construction costs and maintenance management fees, civil engineering costs, mechanical construction costs, electrical / surveying construction costs, testing and operation costs, building construction costs, calculation of annual maintenance and management fees, total LCC, etc.

[0150] Then, after calculating the construction cost based on the design through the construction cost calculation operation S140, the expected outflow water quality and construction cost output operation S150 is executed.

[0151] In the expected effluent quality and construction cost output operation S150, the expected effluent quality and construction cost corresponding to each process configuration 20 are output.

[0152] Specifically, in the output operation S150 of the expected outflow water quality and construction cost, the design calculations, expected outflow water quality and construction cost of the entire process configuration 20 that meet the target water quality can also be output.

[0153] In addition, in the output operation S150 of expected effluent quality and construction cost, multiple process configurations 20 can be output, and the design calculations, expected effluent quality and construction cost of each process configuration can also be output.

[0154] The output unit 130 of the automatic design system 10 performs the output operation S150 of the expected outflow water quality and construction cost.

[0155] Meanwhile, in the expected outflow water quality and construction cost output operation S150, when it is determined that the process configuration 20 does not meet the target water quality, one or more process configurations 20 are derived again based on the basic design information through the simulation execution operation S120.

[0156] Then, in the expected effluent quality and construction cost output operation S150, the expected effluent quality is generated again based on the exported process configuration 20, the mass balance, and the design calculations.

[0157] Here, in order to perform the simulation operation S120 again, analysis / learning techniques are used.

[0158] On the other hand, in the expected outflow water quality and construction cost output operation S150, when it is determined that the process configuration 20 meets the target water quality, the scheme generation operation S160 is executed.

[0159] In the scheme generation operation S160, a design scheme is generated, which includes at least one of the design calculations generated by the simulation execution operation S120, the design drawings generated by the drawing generation operation S130, and the expected outflow water quality and construction cost output by the expected outflow water quality and construction cost output operation S150.
