Referring to fig. 1, fig. 1 is a flowchart of a method for creating a wading enterprise database for an industrial pollution source according to the present invention.
In one specific embodiment, the method for creating the wading enterprise database for the industrial pollution source provided by the invention comprises the following steps of:
s110: in a target flow field, acquiring basic information and pollution source information of all wading enterprises from at least two data sources;
s120: integrating and correcting the pollution source information acquired from different data sources to acquire pollution source data; integrating and checking basic information acquired from different data sources to obtain enterprise data;
s130: constructing a database of wading enterprises in the target river basin based on the enterprise data and the pollution source data; the wading enterprise database information at least comprises the conditions of an enterprise geographic position coordinate, an industry category, water intake, water discharge, a water discharge period, a receiving water body and the like.
Specifically, the basic information of the wading enterprises comprises the city, county, village, latitude and longitude, industry category, whether the wading enterprises belong to a groundwater high-sulfur area, whether the wading enterprises belong to a groundwater high-fluorine area, whether sulfate is discharged, the main links of sulfate discharge, whether fluoride is discharged and the main links of fluoride discharge. Industry category referring to national economic industry Classification (GB/T4754-2017), the specific industry category to which the main product produced under the normal production condition belongs (generally, the main product occupies a larger proportion in the total industrial yield value) is confirmed; whether the underground water belongs to a high sulfur zone and a high fluorine zone of the underground water is mainly referred to the underground water condition and the on-site monitoring result; whether to discharge sulfate and fluoride is determined mainly in combination with industry category and main process links.
The water intake condition includes water intake source (groundwater/surface water), water intake amount, water intake fluoride concentration, water intake sulfate concentration, whether exceeding standard. The concentration of the water taking sulfate and the fluoride is judged according to the requirements that the limit value of the sulfate in the class I, the class II, the class III, the class IV and the class V in the groundwater quality standard (GB/T14848-2017) is less than or equal to 50mg/L, less than or equal to 150mg/L, less than or equal to 250mg/L, less than or equal to 350mg/L and more than 350mg/L respectively, and the limit value of the fluoride in the class I, the class II, the class III, the class IV and the class V is less than or equal to 1.0mg/L, less than or equal to 2.0mg/L and more than 2.0mg/L respectively.
The drainage conditions include the amount of drainage water, the drainage direction, whether the external environment is directly discharged (directly discharged from rivers, lakes and seas, discharged from the rivers, lakes and seas through a pipe network), the concentration of drainage fluoride, the concentration of drainage sulfate and whether the standard is exceeded. The drainage includes directly entering sea area, directly entering water environment such as rivers, lakes and reservoirs, entering urban sewer (reentry into rivers, lakes and reservoirs), entering urban sewer (reentry into coastal sea area), directly entering sewage irrigation farmland, entering ground infiltration or evaporation field, and other types, wherein the waste water is indirectly discharged into the environment to fill in the names of the wastewater treatment plants. The concentration of the fluoride and the sulfate in the drainage is determined based on the monitoring result according to the requirements that the limit values of the fluoride key protection area and the general protection area in the comprehensive emission standard of the water pollutants in a certain province are 2mg/L and 3mg/L respectively, and the limit values of the sulfate key protection area and the general protection area are 650 mg/L.
The water receiving conditions comprise the name of the water receiving body, the functional target of the water receiving body, the name of the downstream section, the fluoride concentration of the section, the sulfate concentration of the section and whether the section exceeds the standard. The concentration of sulfate and fluoride is determined based on the monitoring result according to the requirements that the limit value of fluoride in class I, class II, class III, class IV and class V in the surface water environment quality standard (GB 3838-2002) is less than or equal to 1.0mg/L, less than or equal to 1.5mg/L and less than or equal to 1.5mg/L respectively, and the standard limit value of sulfate serving as a surface water source of centralized domestic drinking water is 250 mg/L.
That is, in the stage of establishing the wading enterprise database, for example, a yellow river basin wading enterprise database is established, in an actual use scenario, the second secondary pollution source census, the pollution discharge permission data, the environment statistics data and the data reported by each market can be combined, pollution source census data is supplemented based on the pollution discharge permission and the environment statistics data, and the integration and the check of the multi-source data are performed, so that the relevant information such as the basic condition, the water taking condition, the water draining condition, the water receiving condition and the like of the wading enterprise is finally defined, and the wading enterprise database is established.
The industrial pollution source wading enterprise database is determined by combining the second national pollution source census (2017), environmental statistics (2020), pollution discharge permission and investigation data, and the integration and check of multi-source data are needed because of the inconsistency of different data source time, statistical caliber, data integrity and the like, so that the database for the industrial pollution source to be investigated is determined. The industrial pollution source wading enterprise database is built by merging and establishing wading enterprises which are incorporated in pollution discharge license supervision, 2020 environmental statistics and 2017 secondary pollution source census enterprises after de-duplication. In addition, related information such as water taking, water draining and the like is mainly studied on site, and the conventional data sources are used as supplements.
In step S110, the basic information and pollution source information of all wading enterprises are obtained from at least two data sources, which specifically includes:
acquiring first basic information and first pollution source information of all wading enterprises from a pre-constructed investigation data database; the method for constructing the investigation data database specifically comprises the following steps:
arranging a plurality of monitoring points in a target river basin, and collecting pollutant emission data of each monitoring point;
taking a wading enterprise generating the pollutant emission data as a target enterprise under the condition that the monitored pollutant emission data reaches a screening threshold value;
traversing all target enterprises obtained from all monitoring points in the target river basin, and integrating the basic information of the target enterprises and the pollution source information of the target enterprises into an investigation data database.
And acquiring second basic information and second pollution source information of the wading enterprise from a public pollution data database. Specifically, basic information and pollution source information of all wading enterprises are respectively obtained from a pollution source general survey database, an environment statistics database and a pollution discharge permission database; and integrating and checking the basic information and pollution source information of all wading enterprises obtained from the pollution source census database, the environment statistics database and the pollution discharge permission database to obtain second basic information and second pollution source information of the wading enterprises.
For example, the pollutant screening database may utilize secondary pollution source screening data, with industrial pollution source screening subjects being all industrial units of industrial activity that produce wastewater pollutants, exhaust pollutants, and solid waste. Basic conditions of enterprises, raw and auxiliary material consumption, product production conditions, pollution-generating facility conditions, various pollutant generation, treatment, emission and comprehensive utilization conditions (including emission port information, emission mode, emission direction and the like), various pollution control facility construction, operation conditions and the like, and wastewater pollutants including chemical oxygen demand, ammonia nitrogen, total phosphorus, petroleum, volatile phenol, cyanide, arsenic, lead, cadmium, chromium and mercury. The second national pollution source screening (2017) period data is 2017.
The environmental statistics database adopts the investigation object of the industrial source in the emission source statistics investigation as mining industry in national economy industry classification (GB/T4754-2017), industrial enterprises (without army enterprises) which are included in important investigation in 3 categories of manufacturing industry, electric power, heating power, gas and water production and supply industry, including various industrial enterprises which are approved and registered by the industrial administration management department and get the business license and industrial enterprises which are not approved by related departments but actually engage in industrial production and operation activities, and have pollutants and greenhouse gas generation or emission. The industrial source investigation method is used for investigating heavy investigation units by families, and the overall estimation of the pollution discharge production condition of non-heavy investigation units is carried out. The screening principle of the key investigation unit takes a municipal administration area as a basic unit, takes a public inspection directory library of a second national pollution source in 2017 as a total sample, and preliminarily determines the discharge amount of wastewater, chemical oxygen demand, ammonia nitrogen, total phosphorus, sulfur dioxide, nitrogen oxides, particulate matters, volatile organic matters and ammonia, the production amount of general industrial solid waste meets the screening definition requirement, and industrial enterprises which are produced by wastewater or waste gas heavy metals (arsenic, cadmium, lead, mercury, hexavalent chromium or total chromium) and have dangerous waste and meet the screening condition of emission source statistics technical regulation as the key investigation unit.
