Method and system for assisting groundwater pollution evaluation

Abstract

The invention relates to the field of groundwater evaluation. The process of groundwater pollution evaluation is divided into an self-help expert system which can be realized in an online and an expert evaluation system which can be realized in an offline way. According to the online expert system, the groundwater pollution assessment is divided into 8 categories, 35 sub categories and hundreds of subdivision tasks. For each subdivision task, the expert system provides a sample answer and a detailed explanation. After technical representatives of a commissioning party are trained in an unified way, the groundwater pollution preliminary evaluation can be carried out independently on the basis of using online resources. A detailed technical document is generated by the preliminary evaluation, and the prototype of an evaluation report is formed. On the above basis, groundwater assessment experts and the technical representatives of the commissioning party carry out project communication in an online way, a groundwater numerical model is subjected to examination and improvement, and an evaluation report draft is modified and processed. When the evaluation is completed, the ability building and fruit transfer of the commissioning party are completed at the same time.

Description

Technical field [0001] The invention relates to the field of water pollution assessment, and in particular to a method and system for assisting in groundwater pollution assessment. Background technique [0002] Groundwater is an important water body on the earth, and groundwater runoff is an important water cycle process; groundwater actively participates in the geological process and the earth's evolution process; it has important ecological functions; groundwater and the rock and soil that occur together constitute the surface stress balance system. At the same time, groundwater has a close relationship with human society. The storage of groundwater is like forming a huge reservoir underground. With its stable water supply conditions and good water quality, it has become an important water source for agricultural irrigation, industrial and mining enterprises, and urban domestic water, and has become an important water resource essential for human society, especially In arid an...

Problems solved by technology

[0010] 1. Information asymmetry between entrusting party and entrusted party leads to low quality of work

[0011] The entrusting party generally appoints a technician from the unit as the project contact person. This contact person is limited by experience and subject background and cannot effectively supervise the entrusted party.

On the other hand, groundwater pollution assessment generally requires the establishment of mathematical models and a large amount of on-site data, and the entrusted party often encounters difficulties when requesting data from the entrusted party

The above-mentioned reality of information asymmetry has led to the low quality of groundwater pollution assessment work and has become a high-occurrence phenomenon

[0012] 2. Substantive results cannot be transferred after the evaluation

Since the entrusting party has no in-depth participation in the evaluation project, the entrusting party has no ability to modify and improve the mathematical model that produces the evaluation results after obtaining further data

[0014] 3. It is extremely difficult for the entrusting party to independently train groundwater pollution assessment talents

[0015] The assessment of groundwater pollution based on numerical simulation is a highly technical and practical professional activity, which not only requires the evaluator to have a professional background in hydrogeology and numerical calculation foundation, but also requires the entrusting unit to have the ability to supervise such projects and cultivate such talents. It is unrealistic to rely solely on short training courses (less than one week) on the existing simulation assessment techniques in the market
