Abstract: A data processing method is disclosed, the method comprising: after data synchronization, obtaining data offset of synchronous data related to a data integration task to be performed, the data offset representing deviation of the synchronous data from corresponding source data; determining whether the synchronous data is complete based on the data offset; in response to the synchronous data being complete, performing the data integration task to the synchronous data.

Abstract: A data management platform for intelligently managing data is provided. The data management platform includes an ETL module configured to extract, cleanse, transform, or load data; a data lake configured to store a first group of data formed by extracting raw data from a plurality of data sources by the ETL module; a data warehouse configured to store a second group of data formed by cleansing and standardizing on the first group of data; a general data layer configured to store a third group of data formed by subjecting the second group of data to data fusion; and a data mart configured to store a fourth group of data formed by transforming the third group of data by the ETL module. The general data layer is a distributed data storage storing information available for querying. The data mart is a database of NoSQL type storing information available for computational processing.

Abstract: Disclosed is a method using an environmental-friendly and artificial freezing technique for sealing and displacement of a soil pollutant. The method for displacement of the soil pollutant comprises: performing an artificial freezing technique on an area and depth of a surveyed contaminated site to form a sealed frozen wall along the perimeter of the contaminated site, by using the excellent permeation resistance function of the frozen wall to seal the contaminated site and to prevent the pollutant from spreading further; selecting a freezing temperature of ?10° C. to ?30° C. according to characteristics of the freezing temperature and precipitation rate of the pollutant, by controlling the freezing rate to 1 cm/day to 10 cm/day, and performing freezing displacement of the soil pollutant from outside to inside using a principle of freezing purification, to concentrate the pollutant; and subjecting the remaining high concentration of contaminated soil to chemical treatment.
