Method for improving dewatering efficiency of antibiotic bacterial residue by sludge hydrothermal carbon and high-pressure filter pressing in cooperation

This invention discloses a method for improving the dewatering efficiency of antibiotic bacterial residue through hydrothermal carbon conditioning combined with high-pressure filtration. The method involves placing sludge in a hydrothermal reaction vessel and carbonizing it at a constant temperature of 180℃–280℃ for 0.5–6 hours. The hydrothermal carbon from the hydrothermal carbonization reaction is then added to antibiotic bacterial residue with a moisture content of 85–98 wt.%, and after thorough mixing with hydrogen peroxide to break down the cell walls, high-pressure filtration is performed to obtain the dewatered antibiotic bacterial residue filter cake. The hydrothermal carbonization technology proposed in this invention requires no additional reagents, and the preparation temperature is lower compared to traditional carbon materials. Compared to traditional thermal treatment dewatering of antibiotic bacterial residue, only a very small proportion of hydrothermal carbon is needed to achieve highly efficient dewatering of the antibiotic bacterial residue, further reducing costs. Furthermore, this invention achieves both efficient dewatering of antibiotic bacterial residue and safe disposal and resource utilization of sludge waste.

Method for manufacturing a semiconductor structure and semiconductor structure

ActiveCN117594524Bhigh nitrogen contentIncreased etch resistanceParasitic capacitorBit line
The present disclosure relates to a semiconductor structure manufacturing method and a semiconductor structure. The semiconductor structure manufacturing method comprises: providing a substrate, the substrate comprising a substrate and a signal line on the substrate; forming at least one initial spacer layer on the sidewall of the signal line, and performing a nitriding treatment on the at least one initial spacer layer to obtain at least one spacer layer. The present disclosure increases the nitrogen content of the nitride layer in the spacer layer by performing a nitriding treatment on the spacer layer as a bit line isolation structure, thereby improving the etching resistance of the spacer layer, improving the sensitivity of the semiconductor device, and ensuring that the semiconductor device has a write recovery time that meets the requirements. At the same time, the increase in the nitrogen content on the nitride layer in the spacer layer reduces the possibility of short bit line contact or loss of bit line isolation structure when the spacer layer is thin. In addition, the nitriding of the oxide layer in the spacer layer can improve the etching resistance of the spacer layer, both increasing the thickness of the oxide layer and reducing the thickness of the nitride layer, thereby improving the problem of bit line parasitic capacitance.
