Method for continuously preparing soft agglomerated nano manganese carbonate

The invention belongs to the technical field of nano materials and particularly relates to a method for continuously preparing soft agglomerated nano magnesium carbonate. Reagent-grade manganese sulfate and a precipitant are used as materials, preventing the reduction in the quality of finished manganese carbonate due to the introduction of impurities to the materials. A continuous feeding mode is used in the synthetic process, so that reaction is continuously carried out and production efficiency is improved. The manganese carbonate prepared herein is less than 30 nm in particle size and is strictly a nano material, the prepared manganese carbonate is spherical and is softly agglomerated, and soft agglomeration is advantageous in that agglomeration easily turns to disagglomeration in use to obtain nanoparticles of primary particle size.

The invention discloses a watershed ecological drought evaluation and prediction method. Currently, ecological drought is not strictly defined, and a drought index framework which is generally applicable and takes ecological health of rivers is not formed yet. A monthly flow process simulated by a vertical mixed production flow model of a watershed grid unit, a P-III distribution function is adopted for fitting theoretical probability distribution, and the skewed distribution is converted into standard normal distribution to obtain ecological drought index value of the watershed. The ecological water demand quantity of a river channel is calculated according to the Tennant method, the ecological runoff quantity values required by different levels are standardized, and the drought level dividing standard of the ecological drought indexes of the watershed is determined. The evaluation range of the current drought index is expanded, and an ecological technical support can be provided forcomprehensive building of a watershed drought early-warning and monitoring system and watershed health. Forecast and prediction can be carried out on further changes of the ecological drought by combining the meteorological and hydrological information.
