The method comprises the following specific steps:
(1) defining a grey water footprint based on dilution effects
Redefining grey water footprints based on 'water environment influence', directly quantifying the influence of the discharge of wastewater pollutants on the water environment in the form of 'diluted water volume', and defining the basic concept as follows: based on the existing environmental water quality standard and the natural water quality, the maximum water quantity required for diluting various potential water environment influences to the natural water quality is the grey water footprint based on dilution influence, and the influence category is a characteristic influence factor.
(2) Determining accounting and evaluation boundaries
According to the research purpose, the life cycle stage of the product is selected, the input of raw materials of each production chain segment and the discharge of wastewater pollutants are determined within the research boundary, the wastewater pollutants are classified according to the influence categories, and the quantity of the discharged wastewater pollutants is determined. The environmental impact categories include water eutrophication, water acidification and water ecotoxicity.
(3) Constructing dilution-influenced gray water footprint accounting and evaluating model
3.1 accounting method for different environmental impact categories
According to the characteristics of complexity and diversity of wastewater pollutants in the production wastewater of textile and clothing products, the environmental influences of the same type caused by different wastewater pollutants have an additive effect. According to different environmental impact categories related to wastewater pollutants discharged in the production of textile and clothing products, the water environmental impact categories are divided into three indexes of water eutrophication, water acidification and water ecological toxicity, and the quantification method is shown in table 1.
TABLE 1 accounting method for different environmental impact categories
3.2 Grey water footprint accounting and evaluating method based on dilution influence
Based on the dilution theory, the water occupied by the potential influence of the water environment caused by the production of the textile and clothing products is diluted by adopting formula 1:
in the formula, GWFinFor grey water footprint based on dilution effects, m3(ii) a k is the environmental impact category, (k is water eutrophication, water acidification, water ecotoxicity);
a characteristic factor of a pollutant i in a k-th influence category; miKg, mass of contaminant i; cmax,iThe maximum allowable concentration of the pollutant i in the existing environmental water quality standard is mg/L; cnat,iIs the natural background concentration of the pollutant i, mg/L.
And (3) diluting each caused environment influence type, wherein the environment influence occupying the most water resource amount is the characteristic environment influence, and the occupied water resource amount is the grey water footprint based on the dilution influence.
The invention is further illustrated by the following specific examples:
taking the water environment influence of the dyeing and finishing chain segment of the cotton textile as an example to carry out accounting and evaluation demonstration. The cotton textile dyeing and finishing chain segment mainly comprises three unit modules of pretreatment, dyeing and after-treatment. And collecting wastewater pollutant discharge data by taking 1000kg of cotton textiles as an accounting functional unit, and performing grey water footprint accounting and evaluation based on dilution influence on dyeing and finishing of the cotton textiles.
Step (1)
According to the discharge data of the pollutants in the cotton textile production wastewater in the dyeing and finishing chain segment boundary, a pollutant discharge list is formulated (see table 2), and the pollutants in the wastewater are classified according to the water environment influence types (see table 3).
Table 2 list of major pollutants in dyeing and finishing chain of cotton textiles
TABLE 3 Classification of wastewater contaminants
Step (2)
2.1 quantifying various classes of Water environmental impact
And (3) according to the wastewater pollutant discharge list and the environmental impact classification formulated in the step (1), accounting is carried out on each water environment impact type of the cotton textile dyeing and finishing chain segment, and the accounting result is shown in a table 4.
TABLE 4 Cotton textile dyeing and finishing Process Each environmental footprint accounting result
2.2 accounting for dilution-impact-based Grey Water footprints
According to the 2.1 accounting result of each environmental footprint, the formula (1) is adopted, the water resource amount occupied by each water environment influence is directly quantified in a 'dilution water volume' form (see table 5), and then the grey water footprint based on dilution influence is obtained (see table 6).
TABLE 5 Cotton textile dyeing and finishing Process Each environmental footprint accounting result
Table 6 cotton textile dyeing and finishing process multiple contaminant grey water footprint based on dilution impact
According to the calculation result, the influences of all processes and all types of water environments of the dyeing and finishing chain segments of the cotton textiles are expressed in the form of a unified unit 'diluted water volume', and the sizes of grey water footprints based on the dilution influences are as follows in sequence: dyeing > after finishing > pre-treatment. Wherein, the three production processes are characterized in that the environmental influence is water ecological toxicity, and the water ecological toxicity influence is far larger than the water eutrophication influence and the water acidification influence.
Through example calculation, it can be seen that the cotton textile dyeing and finishing segment gray water footprint accounting method based on dilution influence considers the water environment accumulation influence caused by different types of wastewater pollutants. The size of potential water environment influences of different types in waste water discharged by a dyeing and finishing process is visually reflected in a form of 'diluting water volume', so that the key problem that quantification index units of multi-dimensional environment influences are not uniform is solved. Further, the process flow can be optimized in a targeted manner, the input of related materials and the output of wastewater pollutants are controlled, and the problem of water environment pollution is effectively reduced and treated.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto.
