  • Publication number: 20250122128
    Abstract: A preparation method of a rice straw biochar loaded with Bacillus cereus, comprising: (1) washing, drying, grinding and sieving rice straws; (2) performing anaerobic pyrolysis treatment on the rice straws treated in the step (1) at 300-700° C. to obtain a biochar; (3) treating the biochar obtained in the step (2) with hydrochloric acid, then washing until a washing solution is neutral, drying, grinding, sieving and sterilizing to obtain a sterilized biochar; and (4) performing mixed culture on the sterilized biochar and a solution of Bacillus cereus subjected to activation culture, and then centrifuging after the end of culture to remove supernatant, so as to obtain a rice straw biochar loaded with Bacillus cereus having a carbon immobilizing capability.

  • Patent number: 11529609
    Abstract: A preparation method of a resin-based iron oxide-containing composite phosphate removal adsorbent is provided. An alkaline anion resin is taken as a base, a potassium ferrate is used as an iron source, and a characteristics of ferrate ions easily adsorbed on a surface of the anion resin are utilized to prepare resin-based iron oxide-containing composite phosphate removal adsorbent by one-step in-situ hydrolysis precipitation, compared with the related art, a preparation process of the disclosure is relatively simpler, a time period is shorter, and a production cost is lower. It has a strong ability to eliminate interference from other anions in the waste effluents, and it has a strong adsorption capacity, fast adsorption speed and large adsorption capacity for the phosphate. Moreover, it has the advantages of strong regeneration ability and multiple repeated use times.
