[0027] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0028] Under the strong interference of human activities, the water ecological process of urban water environment is undergoing profound changes. The original and secondary water-related problems such as water shortage, water environment pollution and water ecological degradation are becoming increasingly prominent. Under the interaction of resource-based and pollution-based water shortage, the water ecological environment is deteriorating, and the restoration and treatment are becoming more difficult, which has become a difficult point in the protection of water ecological environment in China.

[0029] The existing engineering guidelines for river management are one-way implementation measures, which cannot set up feedback mechanisms according to actual conditions, cannot guarantee the implementation effect of each stage and adjust the scheme in real time, and therefore cause the instability of the management effect. On the other hand, in the process of engineering implementation, different indicators are concerned corresponding to different ecological recovery stages, and the indicators of different stages cannot be focused on, which not only makes it difficult to focus on the management problem, but also increases the monitoring cost and management cost.

[0030] In fact, the ecological recovery of a polluted river in a basin is a continuous and gradual process, and the ecological recovery paths of different rivers are not exactly the same and need to be adjusted to local conditions. In the gradual process, the goals implemented at each stage are different, and the indicators of the sections focused on are also different. These indicators are the test standards for the implementation results of the previous stage and the key points for determining the next stage. However, there is still a lack of implementation plans and paths for the ecological recovery of rivers with different degrees of pollution under strong human activities with a feedback mechanism. Considering that the ecological recovery of rivers in a basin is a systematic and multi-coupling progressive process, in the implementation process of the ecological recovery of a polluted river in a strong human activity basin, the actual situation of the basin should be combined with the index feedback to implement the stage-by-stage goals, and the implementation plan should be flexibly adjusted according to the index feedback.

[0031] Based on this, the ecological recovery method, device and electronic equipment provided by the embodiment of the present application can obtain the state information of the polluted river, determine the implementation starting stage and the ecological recovery target based on the state information, determine the feedback index, the sub-feedback index corresponding to the feedback index and the implementation plan corresponding to the implementation starting stage based on the implementation starting stage, determine the first importance order of the implementation plan based on the feedback index, the sub-feedback index and the ecological recovery target, implement the implementation plan according to the first importance order to obtain the implementation result, finally determine the second importance order of the implementation plan based on the implementation result, and implement the implementation plan according to the second importance order until the implementation starting stage meets the ecological recovery target, and then the next implementation stage after the implementation starting stage is implemented, so that the next implementation stage meets the corresponding ecological recovery target. In this way, the feedback index and the sub-feedback index of different implementation stages can be targeted, the problem can be accurately focused on, the monitoring cost and the treatment cost can be reduced, and the stability of the ecological recovery can be improved according to the implementation result.

[0032] In order to facilitate the understanding of the embodiment, first, a method for ecological recovery of a polluted river in a basin disclosed by the embodiment of the present application is introduced in detail.

[0033] Embodiment 1

[0034] The embodiment of the present application provides a method for ecological recovery of a polluted river in a basin. Fig. 1a is a flow chart of the method for ecological recovery of a polluted river in a basin provided by the embodiment of the present application. As shown in Fig. 1a, the method for ecological recovery of a polluted river in a basin can include the following steps:

[0035] In step S101, the state information of the polluted river is obtained.

[0036] The state information includes river water quantity information, river water quality information and river biodiversity information, and the state information of the polluted river can be obtained through water quality, water quantity and biological monitoring.

[0037] In step S102, a starting stage of implementation and an ecological recovery target are determined based on the state information.

[0038] The starting stage of implementation of the ecological recovery includes: a stage of reducing pollution into a river basin, a stage of regulating internal source pollution in a river channel, a stage of guaranteeing ecological base flow of a river, and a stage of reconstructing ecological space in a river basin.

[0039] The ecological recovery target corresponding to the stage of reducing pollution into a river basin is overall black elimination, the ecological recovery target corresponding to the stage of regulating internal source pollution in a river channel is stable black elimination, the ecological recovery target corresponding to the stage of guaranteeing ecological base flow of a river is water quality improvement, and the ecological recovery target corresponding to the stage of reconstructing ecological space in a river basin is ecological restoration.

[0040] Specifically, in the case that the river water quality information is of a first category, the starting stage of implementation is the stage of reducing pollution into a river basin.

[0041] The first category represents that the river water quality is between obvious blackening and stench to inferior V-class water quality.

[0042] Specifically, in the case that the river water quality information is of a second category and a sewage management system is previously set in the river basin of the polluted river, if a specified index in the river basin of the polluted river is not up to standard, the starting stage of implementation is the stage of regulating internal source pollution in a river channel.

[0043] The specified index can be a concentration of a nutrient salt pollutant, a concentration of a heavy metal pollutant, and a concentration of a trace pollutant, and the specified index not up to standard means that the specified index exceeds a pre-set concentration threshold.

[0044] The second category represents that the river water quality is at or better than V-class water quality, and the sewage management system can include a perfect rain and sewage pipe network system and a sewage treatment facility.

[0045] Specifically, in the case that the river water quality information is of the second category and the sewage management system is not previously set in the river basin of the polluted river, the starting stage of implementation is the stage of reducing pollution into a river basin.

[0046] Specifically, in the case that the river water quality information is of the second category and the sewage management system is previously set in the river basin of the polluted river, if the river water quantity information and the river water quality information are both up to standard, and the river biodiversity information represents a to-be-recovered condition, the starting stage of implementation is the stage of reconstructing ecological space in a river basin.

[0047] Specifically, in the case that the river water quality information is of the second category and the sewage management system is previously set in the river basin of the polluted river, if the river water quantity information is river water quantity deficiency, the starting stage of implementation is the stage of guaranteeing ecological base flow of a river.

[0048] Specifically, in the case that the river water quality information is the second category and the sewage management system is pre-set in the basin of the polluted river, if the river water quantity information and the river water quality information are both up to standard and the river biodiversity information represents the condition to be recovered, the implementation starting stage is the stage of reconstructing the ecological space of the basin.

[0049] In step S103, the feedback index, the sub-feedback index corresponding to the feedback index, and the implementation scheme corresponding to the implementation starting stage are determined based on the implementation starting stage.

[0050] The feedback index can include physical index, chemical index, nutrient salt index, municipal index, unconventional index, hydrology index, and ecological index.

[0051] The sub-feedback index corresponding to the physical index can include transparency and odor; the sub-feedback index corresponding to the chemical index can include chemical oxygen demand (COD), dissolved oxygen, potential of hydrogen (PH), oxidation-reduction potential, chlorophyll, and dissolved organic carbon; the sub-feedback index corresponding to the nutrient salt index can include ammonia nitrogen, total nitrogen, and total phosphorus; the sub-feedback index corresponding to the municipal index can include pipe network density, sewage collection rate, rain and sewage pipe network diversion ratio, domestic sewage treatment rate, and sewage pipe access point of drainage area; the sub-feedback index corresponding to the unconventional index can include unconventional pollutants according to the actual conditions of the basin, such as heavy metals, persistent organic pollutants, etc.; the sub-feedback index corresponding to the hydrology index can include flow rate, water level, and water system connectivity; and the sub-feedback index corresponding to the ecological index can include biodiversity, indicator species, number of water bodies in which native fish or aquatic plants are reproduced, proportion of river ecological shoreline, length of greenway construction, and ecological space connectivity.

[0052] The implementation scheme corresponding to the stage of reducing pollution into the river basin includes: weaving nets into pieces, clearing the source, dredging the river, and upgrading and improving the water plant; the implementation scheme corresponding to the stage of treating the endogenous pollution in the river includes: pipe network dredging and river dredging; the implementation scheme corresponding to the stage of guaranteeing the ecological base flow of the river includes: ecological water regulation and replenishment and reclaimed water replenishment; and the implementation scheme corresponding to the stage of reconstructing the ecological space of the basin includes: small lake pond reservoir regulation, artificial wetland, and landscape corridor.

[0053] The feedback index corresponding to the stage of reducing pollution into the river basin can include physical index, chemical index, nutrient salt index, and municipal index. The sub-feedback index corresponding to the physical index is transparency and odor; the sub-feedback index corresponding to the chemical index is COD; the sub-feedback index corresponding to the nutrient salt index is ammonia nitrogen and total phosphorus; and the sub-feedback index corresponding to the municipal index is pipe network density, sewage collection rate, rain and sewage pipe network diversion ratio, domestic sewage treatment rate, and sewage pipe access point of drainage area.

[0054] The feedback indicators corresponding to the stage of treating the endogenous pollution of the river channel can include physical indicators, chemical indicators, nutrient salt indicators, and unconventional indicators. The sub-feedback indicators corresponding to the physical indicators are transparency and odor; the sub-feedback indicators corresponding to the chemical indicators are dissolved oxygen, pH, oxidation-reduction potential, chlorophyll, dissolved organic carbon, and COD; the sub-feedback indicators corresponding to the nutrient salt indicators are ammonia nitrogen, total nitrogen, and total phosphorus; and the sub-feedback indicators corresponding to the unconventional indicators are unconventional pollutants determined according to the actual situation of the river basin.

[0055] The feedback indicators corresponding to the stage of guaranteeing the ecological base flow of the river can include chemical indicators, nutrient salt indicators, and hydrodynamic indicators. The sub-feedback indicators corresponding to the chemical indicators are dissolved oxygen, pH, oxidation-reduction potential, chlorophyll, dissolved organic carbon, and COD; the sub-feedback indicators corresponding to the nutrient salt indicators are ammonia nitrogen, total nitrogen, and total phosphorus; and the sub-feedback indicators corresponding to the hydrodynamic indicators are flow velocity and water level.

[0056] The feedback indicators corresponding to the stage of reconstructing the ecological space of the river basin can include chemical indicators, nutrient salt indicators, and ecological indicators. The sub-feedback indicators corresponding to the chemical indicators are dissolved oxygen, pH, oxidation-reduction potential, chlorophyll, dissolved organic carbon, and COD; the sub-feedback indicators corresponding to the nutrient salt indicators are ammonia nitrogen, total nitrogen, and total phosphorus; and the sub-feedback indicators corresponding to the ecological indicators are biodiversity.

[0057] It should be noted that the feedback indicators, the sub-feedback indicators, and the implementation schemes can be adjusted according to actual concerns, technical progress, and the like.

[0058] Step S104, determining a first importance ranking of the implementation schemes based on the feedback indicators, the sub-feedback indicators, and the ecological recovery target.

[0059] In the determination of the first importance ranking, the first weight order of the feedback indicators and the second weight order of the sub-feedback indicators can be determined simultaneously. Specifically, the weight values of the feedback indicators and the weight values of the sub-feedback indicators can be determined by constructing a fuzzy complementary matrix, and the weight values of the feedback indicators and the weight values of the sub-feedback indicators are sorted respectively to obtain the first weight order and the second weight order.

[0060] The comprehensive weight values of the relative ecological recovery targets can be determined by the weight values of the sub-feedback indicators, and the first importance ranking of the implementation schemes can be determined by the comprehensive weight values.

[0061] Step S105, implementing the implementation schemes according to the first importance ranking to obtain an implementation result.

[0062] The first importance ranking represents the order of implementation of the various embodiments, and the embodiments are implemented in the order of the first importance ranking to treat the polluted river in the basin.

[0063] The implementation result can represent whether the feedback indicators and / or the sub-feedback indicators meet the standards.

[0064] Specifically, after the implementation of the embodiments according to the first importance ranking, whether the feedback indicators and the sub-feedback indicators meet the standards is investigated based on the first weight order and the second weight order; and the meeting of the standards of the feedback indicators and the sub-feedback indicators is taken as the implementation result.

[0065] The first weight order represents the importance ranking of the feedback indicators, and the second weight order represents the importance ranking of the sub-feedback indicators; if the feedback indicators and the sub-feedback indicators with the highest weights meet the standards, it can be considered that the corresponding stages have completed the ecological recovery target.

[0066] In step S106, the second importance ranking of the implementation scheme is determined based on the implementation result, and the implementation scheme is implemented according to the second importance ranking until the implementation starting stage meets the ecological recovery target.

[0067] If the implementation result represents that the feedback indicators and / or the sub-feedback indicators do not meet the standards, the second importance ranking of the implementation scheme is determined based on the feedback indicators after the implementation of the implementation scheme and the sub-feedback indicators after the implementation of the implementation scheme.

[0068] The feedback indicators and the sub-feedback indicators are investigated after each implementation of the implementation scheme, and in the case that the feedback indicators and / or the sub-feedback indicators do not meet the standards, the importance ranking of the implementation scheme is updated based on the feedback indicators and the sub-feedback indicators, and the implementation is continued according to the importance ranking until the implementation starting stage meets the ecological recovery target.

[0069] The weight value of the feedback indicators is determined based on the fuzzy complementary matrix; and the comprehensive weight value of the sub-feedback indicators is determined based on the weight value of the feedback indicators and the weight value of the sub-feedback indicators.

[0070] In step S107, if the implementation starting stage is not the last implementation stage of the ecological recovery, the next implementation stage after the implementation starting stage is implemented to make the next implementation stage meet the corresponding ecological recovery target.

[0071] The implementation stages of ecological recovery can be in the following order: reducing pollution into the river basin stage, rectifying endogenous pollution in the river channel stage, ensuring ecological base flow of the river stage, and reconstructing ecological space in the river basin stage. When one implementation starting stage is carried out and the corresponding ecological recovery target is met in the implementation starting stage, the next implementation stage is carried out until all subsequent implementation stages meet the corresponding ecological recovery target.

[0072] For example, the implementation starting stage is the reconstructing ecological space in the river basin stage, and after the corresponding ecological recovery target is met in the reconstructing ecological space in the river basin stage, the pollution river is treated.

[0073] For example, the implementation starting stage is the rectifying endogenous pollution in the river channel stage, and after the corresponding ecological recovery target is met in the rectifying endogenous pollution in the river channel stage, the river ecological base flow guarantee stage and the reconstructing ecological space in the river basin stage are required to meet the corresponding ecological recovery target in turn before the pollution river is treated.

[0074] In practical application, the most concerned feedback indicators, sub-feedback indicators and the most effective implementation scheme in the river basin can be selected according to different river characteristics and implementation schemes. Based on this, a feedback mechanism in the implementation process of ecological recovery of the polluted river in the river basin is formed, which can not only make decisions according to local conditions, but also adjust the implementation scheme and the ecological recovery target in real time, and has strong flexibility and accuracy.

[0075] For the convenience of understanding, FIG. 1b is an implementation flowchart of the ecological recovery method of the polluted river in the river basin provided by the embodiment of the present application, as shown in FIG. 1b, regarding the ecological recovery path of the polluted river in the river basin, the state information of the polluted river is obtained, then the implementation starting stage and the ecological recovery target are determined according to the state information, then the implementation scheme corresponding to the implementation starting stage is determined, and whether to enter the next implementation stage is evaluated according to the feedback indicators after the implementation scheme is implemented, until the corresponding ecological recovery target is completed.

[0076] In the implementation starting stage, if the river water quality information is the first category, the implementation starting stage is the reduction of basin pollution into river stage; if the river water quality information is the second category and the basin of the polluted river is provided with a sewage management system in advance, if the designated index in the basin of the polluted river does not meet the standard, the implementation starting stage is the regulation of river in-source pollution stage; if the river water quality information is the second category and the basin of the polluted river is not provided with a sewage management system in advance, the implementation starting stage is the reduction of basin pollution into river stage; if the river water quality information is the second category and the basin of the polluted river is provided with a sewage management system in advance, if the river water quantity information is river water quantity deficiency, the implementation starting stage is the guarantee of river ecological base flow stage; if the river water quality information is the second category and the basin of the polluted river is provided with a sewage management system in advance, if the river water quantity information and the river water quality information both meet the standard, and the river biodiversity information represents the condition of being to be recovered, the implementation starting stage is the reconstruction of basin ecological space stage.

[0077] The implementation schemes of the reduction of basin pollution into river stage, the regulation of river in-source pollution stage, the guarantee of river ecological base flow stage and the reconstruction of basin ecological space stage each have a corresponding first importance order, and the implementation of the implementation scheme is started from the first importance order corresponding to the implementation starting stage to implement the basin polluted river, and in the process of implementation, the current ecological recovery condition is judged by whether the sub feedback index meets the standard, the ecological recovery target corresponding to the implementation scheme is confirmed to be completed in the case that the sub feedback index meets the standard, and the second importance order of the implementation scheme is determined again according to the feedback index after implementation and the sub feedback index after implementation to continue the implementation in the case that the sub feedback index does not meet the standard, until the ecological recovery target is completed.

[0078] The ecological recovery method of the basin polluted river provided by the embodiment of the application can obtain the state information of the polluted river, determine the implementation starting stage and the ecological recovery target based on the state information, determine the feedback index, the sub feedback index corresponding to the feedback index and the implementation scheme corresponding to the implementation starting stage based on the implementation starting stage, determine the first importance order of the implementation scheme based on the feedback index, the sub feedback index and the ecological recovery target, implement the implementation scheme according to the first importance order to obtain the implementation result, finally determine the second importance order of the implementation scheme based on the implementation result, implement the implementation scheme according to the second importance order, until the implementation starting stage meets the ecological recovery target, and then the next implementation stage after the implementation starting stage is implemented, so that the next implementation stage meets the corresponding ecological recovery target. In this way, the feedback index and the sub feedback index of different implementation stages can be targeted, the problem of governance can be accurately focused, the monitoring cost and the governance cost are reduced, and the implementation scheme can be adjusted in real time according to the implementation result, and the stability of ecological recovery is improved.

[0079] Embodiment 2

[0080] The embodiment of the present application also provides another ecological recovery method of a river polluted by a basin; the method is realized on the basis of the method of the embodiment; and the method mainly describes a specific implementation manner of determining the first importance ranking of an implementation scheme based on feedback indexes, sub-feedback indexes and ecological recovery targets.

[0081] FIG. 2 is a flowchart of another ecological recovery method of a river polluted by a basin provided by the embodiment of the present application; as shown in FIG. 2, the first importance ranking of the implementation scheme based on the feedback indexes, the sub-feedback indexes and the ecological recovery targets can include the following steps:

[0082] In step S201, the feedback indexes are analyzed two by two to construct a fuzzy complementary matrix.

[0083] In the step, the feedback indexes are scaled according to a preset number of scales, which can be scaled by human marking, such as marking by experts, designers, operation and maintenance personnel, the public, etc., or machine marking, such as marking by a pre-trained model.

[0084] Specifically, the number of scales can be 0.1-0.9; the number of scales of 0.1-0.4 represents that if element ai is compared with element aj to obtain judgment rij, then the judgment obtained by comparing element aj with element ai is rij=1-rji; the number of scales of 0.5 represents that the two elements are equally important; the number of scales of 0.6 represents that one element is slightly more important than the other element in the comparison of the two elements; the number of scales of 0.7 represents that one element is slightly more obvious than the other element in the comparison of the two elements; the number of scales of 0.8 represents that one element is much more important than the other element in the comparison of the two elements; and the number of scales of 0.9 represents that one element is extremely more important than the other element in the comparison of the two elements.

[0085] For the convenience of understanding, taking the stage of reducing basin pollution into a river as an example, the constructed fuzzy complementary matrix of the feedback indexes is shown in Table 1.

[0086] Table 1

[0087] In the table, A represents the stage of reducing basin pollution into a river, B1 represents a physical index corresponding to the stage of reducing basin pollution into a river, B2 represents a chemical index corresponding to the stage of reducing basin pollution into a river, B3 represents a nutrient salt index corresponding to the stage of reducing basin pollution into a river, B4 represents a municipal index corresponding to the stage of reducing basin pollution into a river, bij represents the number of scales of Bi compared with Bj. ri represents the sum of the numbers of scales of the i-th row, and bk represents the number of scales of the k-th feedback index.

[0088] Step S202, determining the weight value of the sub-feedback index based on the fuzzy complementary matrix.

[0089] wherein the sum of each row of the matrix B = bij (n x n) is ri represents the ith row, that is, the index B1 relative to, bik represents the scale quantity corresponding to the kth column of the ith row, that is, the importance of the ith index relative to the jth index, and n represents the feedback index participating in the scale.

[0090] Further, by obtaining a fuzzy consistency matrix R = (rij) n x n, and performing normalization processing on the matrix R to obtain a factor ordering vector W = (W1, W2,..., Wn) T wherein the W vector satisfies wherein n represents the matrix order, a = (n-1) / 2, and ∑W i = 1.

[0091] For the convenience of understanding, taking the stage of reducing pollution into river basin as an example, the fuzzy consistency matrix and the weight value are shown in Table 2.

[0092] Table 2

[0093] Wherein, the weight value of the feedback index shows the importance degree of the feedback index in the corresponding implementation stage, the greater the weight value, the more important the feedback index, and the weight value of the sub-feedback index is calculated in the same way.

[0094] Step S203, determining the comprehensive weight value of the relative ecological recovery target based on the weight value of the sub-feedback index.

[0095] Specifically, determining the comprehensive weight value of the relative ecological recovery target based on the weight value of the sub-feedback index can include: comparing the weight values of the alternative implementation schemes based on the weight values of the sub-feedback indexes, to obtain the weight values of the alternative implementation schemes; and determining the comprehensive weight value of the relative ecological recovery target based on the weight values of the alternative implementation schemes.

[0096] Wherein, the alternative implementation scheme is at least one of the implementation schemes.

[0097] Wherein, the comprehensive weight value of the sub-feedback index can be determined based on the weight value of the sub-feedback index, and the comprehensive weight value of the alternative implementation scheme relative to the ecological recovery target is calculated in combination with the comprehensive weight value of the sub-feedback index.

[0098] For the convenience of understanding, the calculation method of the comprehensive weight value of the sub-feedback indicators is shown in Table 3, taking the stage of reducing pollution into a river basin as an example. In Table 3, the transparency and odor are the sub-feedback indicators corresponding to the physical indicators of the stage of reducing pollution into a river basin, the COD is the sub-feedback indicator corresponding to the chemical indicators of the stage of reducing pollution into a river basin, the ammonia nitrogen and total phosphorus are the sub-feedback indicators corresponding to the nutrient salt indicators of the stage of reducing pollution into a river basin, and the pipe network density, sewage collection rate, rain and sewage pipe network diversion ratio, domestic sewage treatment rate, and sewage pipe access point of a drainage area are the sub-feedback indicators corresponding to the municipal indicators of the stage of reducing pollution into a river basin.

[0099] Table 3

[0100] For the convenience of understanding, the calculation method of the comprehensive weight value of the sub-feedback indicators is shown in Table 3, taking the stage of reducing pollution into a river basin as an example. In Table 3, the transparency and odor are the sub-feedback indicators corresponding to the physical indicators of the stage of reducing pollution into a river basin, the COD is the sub-feedback indicator corresponding to the chemical indicators of the stage of reducing pollution into a river basin, the ammonia nitrogen and total phosphorus are the sub-feedback indicators corresponding to the nutrient salt indicators of the stage of reducing pollution into a river basin, and the pipe network density, sewage collection rate, rain and sewage pipe network diversion ratio, domestic sewage treatment rate, and sewage pipe access point of a drainage area are the sub-feedback indicators corresponding to the municipal indicators of the stage of reducing pollution into a river basin.

[0101] Table 4

[0102] In step S204, the first importance ranking of the implementation scheme is determined based on the comprehensive weight value.

[0103] The first importance ranking is obtained by ranking the implementation schemes based on the comprehensive weight value of the implementation schemes relative to the ecological recovery target.

[0104] The ecological recovery method of the river basin pollution river provided by the embodiment of the present application can determine the weight value of the feedback indicators and the sub-feedback indicators corresponding to the implementation stage and the weight of the corresponding implementation scheme based on the fuzzy multi-level analysis feedback method. The importance ranking of the implementation scheme in the implementation stage and the weight ranking of the feedback indicators and the sub-feedback indicators are determined, and then the implementation scheme is executed through the importance ranking, and it is examined whether the ecological recovery target is achieved through the weight ranking, the monitoring cost and the treatment cost are reduced, and the stability of the ecological recovery is improved.
