Technical Field

[0001] The present application relates to the technical field of heavy metal pollution control plant treatment, and in particular to a vegetation post-treatment method and system for heavy metal pollution control. Background Art

[0002] Affected by various human activities, some soils will be contaminated by heavy metals. For heavy metal pollution, phytoremediation technology is relatively cheap and more suitable for large-scale land pollution. It not only requires less capital investment, but also can use plants to beautify the environment.

[0003] However, how to deal with heavy metals after they are absorbed and enriched by plants is a problem. If they are not handled properly, it is easy to cause secondary pollution. At present, ramie is used as a restoration plant, and its resources can be used in the later stage, such as as a textile raw material, so as to reduce the occurrence of secondary pollution; however, due to the influence of soil properties, temperature and humidity, plant restoration may not be suitable for ramie, but also for other shrubs and herbaceous plants. Therefore, it is necessary to propose a new heavy metal treatment plant treatment plan. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 2 It is a schematic diagram of the plant circulation of the method of the present application. DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-2 This application is described in further detail.

[0042] The embodiment of the present application discloses a vegetation post-treatment method for heavy metal pollution control.

[0043] Reference Figure 1-2 , the post-treatment methods of vegetation for heavy metal pollution control include:

[0044] Step 1: Determine the treatment method for controlling the plants, which includes:

[0045] 1) Burning the treated plants to obtain wood ash, which is used to add to metal smelting for resource recycling; this method is the main tendency of this application. Adding a proper amount of wood ash during metal smelting processes such as steelmaking can help remove impurities in the alloy melt; at the same time, some metal elements enriched in plants can return to the resource path during the alloy smelting extraction process.

[0046] 2) If the treated plants include textile raw material plants such as ramie, they can be used as textile raw materials.

[0047] Step 2: Reuse and allocation of plant ash resources. It should be noted that if the air pollution caused by combustion is taken into consideration, the treated plants can be transported to alloy smelting units (factories) for burning into ash; if only the transportation cost is considered, they can be burned in heavy metal treatment plots; in this embodiment, the first burning option is preferred.

[0048] Regarding the reuse and allocation of wood ash resources, it can be realized with the help of computers, specifically:

[0049] 1) Obtain the identification information (name, number), location information and heavy metal content information of the heavy metal contaminated land, and obtain the name, location and production information of the metal smelting unit with which cooperation has been established in advance (willing to accept the supply of grass and trees).

[0050] Among them, production information includes the type of smelting metal, the composition of the ore used, the smelting process and the production plan.

[0051] 2) Obtain plant ash demand information based on production information analysis; plant ash demand information includes demand units and demand quantities. For example, the purpose of this production information is to determine whether plant ash can be added based on the process (experience process) and to determine the unit usage if it can be added; another purpose is to calculate how much plant ash is needed based on the production plan.

[0052] 3) Based on the demand information of wood ash and various information of heavy metal contaminated plots, the production and distribution of wood ash are analyzed, and the treatment plant processing and distribution plan is obtained and sent to the management unit / personnel of the corresponding supply plot.

[0053] According to the above content, this method allows heavy metal pollution control plants to be recycled in the form of wood ash, so the treatment method is relatively not restricted by plant species; at the same time, it can also analyze various information of heavy metal polluted plots and various information of metal smelting units to provide processing and distribution plan prompts for relevant units / personnel, helping relevant personnel to relatively conveniently carry out harmless treatment of more soil-remediated plants.

[0054] The above analysis of plant ash production and distribution includes:

[0055] 1) Obtain the delivery distance based on the location information of the heavy metal contaminated land and the demand unit. This link can be obtained by importing the location information into the navigation platform.

[0056] 2) Calculate freight based on delivery distance and get estimated freight.

[0057] There are at least two situations in this link. One is that the staff manually determines the freight per ton per kilometer and then calculates it; the other is to connect to a third-party freight intermediary platform, obtain the platform's real-time quotation and then calculate it.

[0058] 3) Select the delivery plots based on the estimated freight and preset delivery rules.

[0059] The supply rules include: priority is given to supply sites with large inventory, priority is given to sites with short delivery distances, and priority is given to sites with low freight costs.

[0060] Because when using plants to repair heavy metal contaminated land, although the plants selected are mostly shrubs and herbs, in order to ensure a certain geographical beauty and super-enrichment utilization rate of plants, the plants are not necessarily harvested when they are seedlings. Therefore, it is necessary to consider the supply of each plot. For this reason, this method also includes:

[0061] 1) Obtain the planting plan of the treatment plants for each heavy metal contaminated land plot; the planting plan includes the planting type, time and area. It should be noted that this area is the actual growth area, which needs to be updated periodically by the staff according to the growth situation, and is not necessarily equal to the initial planting area.

[0062] 2) Determine the harvestable plant area based on the planting plan of the managed plants and the preset harvesting rules.

[0063] Harvesting specifications include: plant A is harvested after growing for T1 time; plant B is harvested after growing for T2 time; A, B, T1 and T2 are all information actively determined by the staff.

[0064] Based on the above, the production and distribution of plant ash is analyzed, including:

[0065] 1) Estimate the inventory supply based on historical harvest inventory records. It should be noted that if the demand information is the ash volume of plant ash, and the supply and inventory are the weight of the plant, it needs to be calculated as the ash volume based on the preset plant unit ash output.

[0066] 2) If the inventory supply is greater than or equal to the demand, generate a new batch supply and update the inventory supply;

[0067] If the inventory supply is less than the demand, an inventory supply reminder is generated based on the difference, and the required harvest quantity / area is calculated to update the harvestable plant area.

[0068] Based on the above content, this method can help staff to manage wood ash supply and manage plant maintenance work more conveniently and reasonably.

[0069] In one embodiment, the above-mentioned plant ash demand information includes the demand time; based on this, the plant ash production and distribution analysis includes:

[0070] 1) Calculate the delivery time based on the delivery distance; similarly, you can import it into the navigation software to get it.

[0071] 2) Calculate the remaining time based on the current time, delivery time and required time; that is, remaining time = required time - current time - delivery time.

[0072] 3) If the inventory supply is less than the demand, the harvest quantity / area prompt of the demand group is output, and the matching estimated harvest time (actively reported by the staff) is received;

[0073] 4) If the estimated harvesting time is longer than the remaining time, the current plot will be eliminated and another supply plot will be selected, and the demand for wood ash will be redistributed according to the preset multi-party supply rules.

[0074] Among them, the multi-party supply rules include: using the difference between inventory supply and demand as the delivery quantity of another supply block.

[0075] Based on the above content, it can prevent the land providing wood ash raw materials from affecting the normal production and processing of metal smelting units due to the inability to supply in time, thereby reducing the resistance of metal smelting units to the reuse of treated plants and making the promotion of harmless treatment of treated plants easier.

[0076] Based on the above, the production and distribution of plant ash is analyzed, including:

[0077] If the estimated harvesting time is less than the remaining time, obtain the weather information of the remaining time of the supply plot;

[0078] If the weather information meets the preset drying conditions (such as cloudy or sunny), the weight loss parameters corresponding to the drying time and the freight savings corresponding to the weight loss parameters are calculated based on the recorded historical drying rates.

[0079] Example: The drying rate of plant A is 30g / day for one unit weight. If 10,000 units are needed, the weight loss on the first day is 30*10,000g, and the weight loss on the second day is 2*30*10,000g...; then, the freight savings can be calculated based on the results.

[0080] Based on the above content, this method can provide a reference for delivery time for management personnel of supply sites and contact personnel of metal smelters, helping them save more freight when conditions permit.

[0081] In one embodiment of the method, the wood ash production and distribution analysis includes:

[0082] 1) Estimate the heavy metal enrichment of various plants in the current plot based on the planting type, time, pre-recorded heavy metal enrichment rate and current time of the treated plants;

[0083] 2) Calculate the maximum impurity content based on the smelting process and production plan. For example, the staff will write down the maximum content of a certain type of metal based on experience to avoid affecting the quality of the alloy or purified product. Alternatively, the process will record the maximum content of other metals other than the required elements in the ore raw materials used. This will calculate the amount of other metals in the process / raw materials for each unit of output. After that, the output in the production plan can be obtained for calculation.

[0084] 3) Analyze the recommended harvesting amount / area of ​​various plants based on the maximum impurity content and heavy metal enrichment of various plants.

[0085] Example: Assume that plants A and B are harvested at x1 and y1 square respectively, the current enrichment of plant A is 1000 mg / square, the current enrichment of plant B is 700 mg / square, and the current limit impurity content is 100*1000 mg, then 100*1000=1000*x1+700*y1; (x1+y1)*preset ash output per square g=demand; thus, the recommended harvesting areas x1 and y1 can be calculated.

[0086] According to the above settings, the interference of wood ash quality differences on metal smelting can be reduced, metal smelting can be prevented from producing unqualified products due to excessive impurities, and frequent changes in metallurgical formulas and processes can be avoided.

[0087] The embodiment of the present application also discloses a vegetation post-processing system for heavy metal pollution control.

[0088] A vegetation post-processing system for heavy metal pollution control includes a memory and a processor, wherein the memory stores a computer program that can be loaded and executed by the processor to implement any of the above-mentioned vegetation post-processing methods for heavy metal pollution control.

[0089] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
