Abstract: Querying a data set formed from a version of primary data and secondary data is facilitated. First and second versions of primary data are stored in a primary data version store. Secondary data is received. The secondary data is stored in a secondary data store. A query language statement is received. The query language statement is executed by selecting query results from a data set that includes the secondary data and elements of the first version of primary data not inconsistent with the secondary data.

Abstract: The present invention provides a TiO2-based coagulant and use thereof. The TiO2-based coagulant is obtained by the following steps: uniformly mixing acetylacetone and ethanol and dropwise adding titanium tetrachloride to obtain a solution A; mixing deionized water and ethanol to obtain a solution B; dropwise adding solution B to solution A; stirring to obtain a sol, and then aging the sol to constant weight to obtain the TiO2-based coagulant. The TiO2-based coagulant can be used for treating waste water and algae-laden water. The TiO2-based coagulant exhibits good coagulation effects and high stability, solves the problem of too low effluent pH caused by strong inorganic titanate acidity and is favorable to the subsequent treatment of waste water.
