The invention belongs to the field of agriculture and forestry recycling, and particularly relates to a method for improving the quality of an organic fertilizer and reducing ammonia emission by conditioning aerobic composting with a hydrothermal carbonized solution. The hydrothermal carbonization liquid is prepared by taking agricultural and forestry wastes as raw materials through a hydrothermal reaction under a certain temperature and pressure condition, and the applicability of the hydrothermal carbonization liquid is further improved through modification measures; the aerobic composting step mainly comprises the following steps: stacking livestock and poultry manure, poplar sawdust and the modified hydrothermal carbonization liquid as fermentation raw materials in an aerobic composting reactor for 20-35 days, turning over for multiple times during the period, and keeping a proper moisture condition, so that the fermentation raw materials are thoroughly decomposed. The hydrothermal ...

The invention provides preparation and application of a functionalized magnetic material for enhancing adsorption of microplastics in a water body, the magnetic material adopts polyethylene glycol to modify the surface of magnetic ferroferric oxide to form a hydroxylated magnetic iron oxide nano material, and the magnetic material has the characteristics of large specific surface area and multiple adsorption active sites, has magnetism and is convenient to recycle. The surface-hydroxylated ferroferric oxide is used as an adsorbent for removing the polyethylene micro-plastic in the water body, the result shows that the hydroxylated adsorbing material can efficiently remove the polyethylene micro-plastic in the water body within a short time, and compared with nano iron oxide without surface modification, the adsorption rate on polyethylene is increased by 54%, and the adsorption rate on polyethylene is increased by 50%. The method verifies that the adsorption rate of ferroferric oxide to ...
