Preparation method and application of cation-modified glycoprotein type microorganism flocculating agent

The invention provides a preparation method and application of a cation-modified glycoprotein type microorganism flocculating agent. The preparation method comprises the following steps: mixing 3-chlorine-2-hydroxypropyl PDMC with a NaOH solution for reaction, adding a glycoprotein type microorganism flocculating agent for mixing, stirring under room temperature for 0.5-2 hours, and reacting under the temperature of 60-90 DEG C for 1-3 hours, thus obtaining the cation-modified glycoprotein type microorganism flocculating agent after purification. The flocculating agent is applied to removal of kaoline from wastewater. The cation-modified glycoprotein type microorganism flocculating agent prepared by the preparation method can effectively cationize a microorganism flocculating agent loaded with negative electricity, so that a flocculating aid used in a microorganism flocculating agent use process is omitted. In the use process, other flocculating aids are not needed, so that suspensions in kaoline simulation wastewater can be removed; therefore the adding process of the flocculating agent is simplified. The method disclosed by the invention finally achieves the effect of simplifying the flocculating agent adding technology, so that the content of inorganic flocculating acid substances in settled sludge is reduced, and secondary pollution caused by the settled sludge to the environment is alleviated.

Data transmission method and device of 5G system

The invention relates to the field of communication, in particular to a data transmission method and device of a 5G system. The data transmission method is used for reducing the load of the system andimproving the processing efficiency, and comprises the steps of: determining a number of data packets to be sent, and determining a threshold value interval corresponding to the current load of the system; then converging the data packets to be sent according to a preset threshold value when determining that the number of the data packets reaches the preset threshold value corresponding to the threshold value interval, and generating a converged data packet; and finally, sending the converged data packet to a receiver, and triggering the receiver to analyze the converged data packet. Thus, the data packets to be sent can be converged into the converged data packet and then sent to the receiver, the message primitive processing number of protocol interlayer interaction is reduced, the header adding process is simplified, the convergence condition is accurately limited, the effectiveness of the processing result is ensured, the load of a system processor is reduced, the processing efficiency is improved, the scheduling frequency is reduced, the operation overhead of the system is reduced, and the resource consumption is reduced.

Double-liquid process grouting material and grouting process using grouting material

The invention discloses a double-liquid process grouting material and a grouting process of the grouting material. The grouting material consists of cement paste and an additive solution, wherein the additive is prepared by mixing 0.38 parts by weight of sodium metasilicate, 0.12 parts by weight of lithium poatassium and 0.5 parts by weight of calcium chloride; and the grouting process comprises respectively preparing paste materials and instantly mixing and grouting via a special double-liquid grouting paste plug. The grouting material disclosed by the invention satisfies the requirement on dam curtain grouting in regions with high cold, low temperature and large temperature difference day and night; the processes of adding complex components are simplified due to the adoption of the processes of randomly mixing, instantly pouring and grouting; and the additive is mixed with cement paste liquid in a hole through double-liquid grouting, so that the conflict between the pumping time and the setting time of the paste liquid is solved. Due to the preparation method, not only the diffusion of the cement paste liquid is effectively controlled and the re-grouting time is reduced, but also the problem of big control difficulty in the setting time of the paste liquid is solved, so that the investment is effectively reduced, the grouting period is shortened, and the grouting quality conforms to the engineering quality requirement.
