This invention belongs to the field of thermal energy recovery and automation control, specifically relating to an intelligent control system for mine water waste heat recovery. The system includes a production condition sensing device, a multi-source thermal monitoring device, an energy value analysis center, a dynamic load dispatching terminal, a multi-media heat exchange actuator, and a flexible thermal energy storage system. The system collects real-time mine production conditions and multi-source thermal parameters, constructs an energy asset model using a discrete state transition probability model, and, based on a game theory bidding mechanism and electricity price fluctuation trend prediction, guides the heat exchange actuator and storage system to perform optimized allocation and predictive storage of thermal energy. This invention transforms fluctuating heat sources into predictable energy assets, achieving the lowest-cost and most energy-efficient energy configuration scheme in a multi-source coupled environment, improving resource utilization, and ensuring the stability of energy supply in the mining area.

The invention provides a constructed wetland treatment system and method and application, and belongs to the technical field of pollutant treatment. The constructed wetland treatment system comprises a constructed wetland pool, a supporting layer and a matrix functional layer are sequentially arranged in the constructed wetland pool from bottom to top, wetland plants are planted on the matrix functional layer, and the matrix functional layer is a mixture of Manchuino ore and quartz sand. According to the invention, the Manchuo mine is used as a matrix filler of an artificial wetland system, and through the electron supply, adsorption and coprecipitation effects of the Manchuo mine, the form of heavy metals is changed, the adsorption of micro-organic pollutants and the adsorption and precipitation of the heavy metals are promoted, and the removal of the heavy metals and part of the micro-organic pollutants is realized; meanwhile, microorganic micropollutants are degraded through a synergistic effect with microbial anabolism and mediated oxidation-reduction reaction thereof and plant assimilation absorption, so that a multifunctional pollutant removal system for the constructed wetland is constructed, and the utilization rate of the constructed wetland is effectively increased while effluent is ensured to meet the national standard.

This invention provides a method for preparing high-proportion aragonite-type calcium carbonate and ammonium sulfate fertilizer by mineralizing CO2 using desulfurized gypsum. The method includes the following steps: First, desulfurized gypsum is mixed with water to obtain a mixture. Ammonia and serine are added to the mixture to obtain a suspension. Second, CO2-containing flue gas is introduced into the bottom of the suspension until the pH of the reaction system reaches approximately 7. The flue gas is then stopped, and solid-liquid separation is performed to obtain a solid product containing a high proportion of aragonite-type calcium carbonate and an ammonium sulfate solution containing heavy metal ions. Finally, the heavy metals in the ammonium sulfate solution are removed, and crystallization is performed to obtain fertilizer-grade ammonium sulfate crystals. This invention features a simple process, yields high-purity aragonite-type calcium carbonate as the solid product, and the prepared ammonium sulfate crystals can be directly used as nitrogen fertilizer in agricultural production. This achieves efficient treatment and resource utilization of desulfurized gypsum, while also capturing and utilizing some CO2 from the flue gas.

The invention relates to the technical field of preparation of adhesives and granular activated carbon, in particular to a composite adhesive, straw-based granular activated carbon and a preparation method. According to the specific technical scheme, firstly, the straw gasification tar is subjected to reduced pressure distillation under specific conditions (light components are removed at the temperature of 100 DEG C, and phenol-rich components are collected at the temperature of 170-250 DEG C) for fractional separation; phenol-rich components are used for partially replacing phenol (the replacement rate is 10-50%), the phenol-rich components react with formaldehyde under the catalysis of potassium hydroxide to synthesize phenolic resin, and sesbania powder is added for thickening. And compounding the thickened phenolic resin with the separated heavy components to obtain the composite adhesive. The adhesive and straw biochar are mixed and molded in proportion, and the straw-based granular activated carbon is prepared through the processes of hardening, carbonization, coupling activation and the like. The carbon tetrachloride adsorption rate of the product is greater than or equal to 60%, the strength is greater than or equal to 90%, and high-value utilization of straw tar and charcoal is realized.
