It will be appreciated that large particulate matter in the leachate may be removed prior to performing the present method.
Organic contaminants: this is the main contaminant in the leachate, mainly from organic matter in landfill waste. These include low molecular weight fatty acids, medium molecular weight fulvic acids and high molecular weight humic acids. In addition, the leachate may contain carcinogenic, teratogenic and carcinogenic substances.
Heavy metal contaminants: the percolate contains various heavy metal ions such as lead, cadmium, mercury, chromium and the like. These heavy metal ions have durability and bioaccumulation, and exert long-term influence on the environment and human health.
The inorganic ions mainly comprise sodium (Na), potassium (K), ammonium (NH4+), iron (Fe), chlorine (Cl), sulfate radical (SO 42-), bicarbonate radical (HCO 3-) and nitrate radical (NO 3), etc. The content of these inorganic ions in the percolate is generally in the order of hundreds to thousands of milligrams per liter. Among these, non-metallic inorganic contaminants are mainly nitrogen (N) and phosphorus (P), which increase in concentration in the leachate over landfill operation time and remain at higher concentrations. This is because the decomposition of waste under anaerobic, anoxic conditions in landfills is a long and slow process, while N and P are the main products of anaerobic fermentation of waste. Inorganic ions in the percolate have a certain influence on the pH value of the percolate, and the change of the pH value can further influence the treatment effect of pollutants in the percolate. Therefore, during the treatment of the percolate, a strict control of the inorganic ion content is required.
Nutrient salt contaminants: the percolate contains a large amount of nutrient salts such as nitrogen, phosphorus and the like, and the nutrient salts can cause eutrophication of the water body and influence the ecological balance of the water body.
Pathogen: the percolate may also contain various pathogens, such as bacteria, viruses, parasites, etc. These pathogens can pose a direct threat to the environment and human health.
It is clear that the related adjustment (treatment and purification) of the concentration of organic matters, the concentration of heavy metals, the concentration of inorganic ions, the pH value, the concentration of nutrient salt pollutants and the pathogen content is the prior art, and the adjustment technology is only needed by referring to the prior art without improvement. For example, adjusting the concentration of the organic matter is to reduce the concentration of the organic matter, and so on. While measures for treating (purifying) organic contaminants belong to the prior art and are not repeated here. When any one of the organic matter concentration, the heavy metal concentration, the inorganic ion concentration, the nutrient salt pollutant concentration and the pathogen content is reduced or the pH value is regulated, the influence among the organic matter concentration, the heavy metal concentration, the inorganic ion concentration, the nutrient salt pollutant concentration, the pathogen content and the pH value is different at different processing temperatures, and the influence degree among the organic matter concentration, the heavy metal concentration, the inorganic ion concentration, the nutrient salt pollutant concentration, the pathogen content and the pH value can be reflected well by adopting a curved surface fitting method, so that the processing efficiency can be improved to the greatest extent.
The method further comprises the following steps:
and (3) data acquisition:
and in the area where more percolate is generated and the mobility is good, periodically collecting percolate samples.
The concentration of each type of contaminant in the test sample is measured and the spatial coordinates (e.g., latitude and longitude or grid coordinates) of the collection point are recorded.
Data preprocessing:
The data is flushed and outliers or erroneous data are removed.
Normalization or normalization of the data may be required to better reflect the trend of the data during the fitting process.
And (3) selecting a curved surface fitting model:
And selecting a proper curve fitting model according to the distribution characteristics of pollutants, the topography and other factors. Common surface fitting models include polynomial surface fitting, radial Basis Function (RBF) networks, kriging interpolation, and the like.
After selecting the appropriate model, parameters of the model, such as fitting order, kernel function, etc., are determined.
Model fitting:
Training is performed by a selected surface fitting model using the collected contaminant concentration data and spatial coordinates.
Model parameters are continuously adjusted to optimize the fitting effect, so that the constructed curved surface can accurately reflect the space distribution rule of pollutants.
Model verification and evaluation:
And verifying the model by using independent sample data which does not participate in training, and evaluating the prediction accuracy of the model.
Common evaluation metrics include Mean Square Error (MSE), root Mean Square Error (RMSE), decision coefficient (R), etc.
Visualization of results:
And (3) visually displaying the fitted curved surface by using a Geographic Information System (GIS) or drawing software, and intuitively presenting the spatial distribution trend of various pollutants and pH values in the percolate.
And (3) pertinence adjustment:
And analyzing diffusion paths and distribution positions of pollutants and pH values according to the curve fitting result, and pertinently adjusting the concentration of real-time organic matters, the concentration of real-time heavy metals, the concentration of real-time inorganic ions, the concentration of real-time pH values, the concentration of real-time nutrient salt pollutants and the content of real-time pathogens based on the diffusion paths and the distribution positions, so that the treatment efficiency is effectively improved.
The process of adjusting the real-time organic concentration may be as follows:
s1, sorting the concentration of organic matters in percolate at different positions based on a diffusion path and a distribution position, wherein the concentration of the organic matters is sequentially a first concentration position and a second concentration position … … n concentration position;
S2, defining a weighted graph G= (V, E), wherein V is a vertex set, V= { a first concentration position, a second concentration position … … n concentration position }, and E is an edge set; each edge (u, v) has a weight w (u, v) representing the distance from the vertex u to the vertex v;
S3, initializing a distance array dist </i >, wherein dist [ i ] represents the shortest distance from a source vertex (here a first concentration position) to the vertex i; initially, dist [ i ] is set to infinity (representing unreachable), dist [ source vertex ] is set to 0;
S4, creating a set S for storing the vertexes which have found the shortest path; at the beginning, S is empty;
The following steps are repeated until S contains all vertices in the graph: a. selecting a vertex u with the smallest dist value from among the vertices in S; b. adding the vertex u to the set S; c. update the distance of all neighbors v of u: if dist [ u ] +w (u, v) < dist [ v ], updating dist [ v ] = dist [ u ] +w (u, v);
S5, after all vertexes are processed, the value in the dist array is the shortest distance from the source vertex to all other vertexes;
S6, after the source vertex is adjusted to the real-time organic matter concentration, based on the shortest distance from the source vertex to all other vertices, carrying out real-time organic matter concentration adjustment on the other vertices which are the shortest distance away from the source vertex, taking the concentration position as the source vertex after the concentration position is adjusted to the real-time organic matter concentration, and removing the previous source vertex (the concentration position of the organic matter concentration which is already adjusted to the real-time organic matter concentration) in V;
S7, performing loop execution S2 to S6.
The process of adjusting the concentration of the heavy metal, the concentration of the inorganic ion, the pH value, the concentration of the nutrient salt pollutant and the pathogen content in real time can refer to the process of adjusting the concentration of the organic matter in real time, and the description is not repeated here.
