The invention relates to improvement of a biological solidification and stabilization method of dredge bottom mud. The biological solidification and stabilization method is characterized by comprising the following steps: primarily dehydrating clay particles which have less possibility of being dehydrated, and mixing and stirring the dehydrated clay particles with dry soil to form mixed soil; and spraying a compound biological enzyme liquid at least consisting of reductase, amylase, cellulase, esterase, lipase, ligninase, prolease, urease, xylanase and a detergent surface active agent to be mixed with the mixed soil, then compacting and solidifying. The biological solidification and stabilization method has the advantages of short process flow and simplicity; by utilizing the method, the volume of the bottom mud to be solidified and stabilized is greatly reduced, the volume of the bottom mud to be solidified after classification and dehydration is 10%-15% of that of the bottom mud to be conventionally solidified, the processing flow is reduced compared with the existing biological enzyme solidification, the solidification cost is reduced, the solidification strength is high, the solidification filling shear strength can reach the Mpa grade, thus the method can be used for road construction, parking lots, slope solidification, reservoir surface solidification, refuse landfill bottom solidification and seepage prevention and public road building. By using the method, the outlet problem of the dredge bottom mud is effectively solved, and a novel decrement and solidification process for the bottom mud in the lakes is created.

The invention relates to a method for improving performances of yarns formed by vortex spinning by reducing the modulus and the rigidity of fibers on line and belongs to the field of textile processing. According to the method disclosed by the invention, a sectional softening treatment method is applied for carrying out progressive softening treatment on fibers subjected to vortex spinning on a vortex spinning machine, and thus the fiber modulus and the bending rigidity are quickly reduced on line and the performances of the resultant yarns prepared from fibers by vortex are improved. For a vortex yarn structure, the structure compactness is improved, the yarn strength is enhanced and residual torque of the yarns is small; in addition, the non-spinning fibers can be subjected to vortex spinning on the vortex spinning machine; the fibers with poorer quality for the resultant yarns formed by the vortex spinning are subjected to high-quality spinning on the vortex spinning machine; and particularly, the improvement on the spun count of the fibers on the vortex spinning machine is facilitated and the smooth production of high grade cotton yarns formed by vortex spinning is realized. The method disclosed by the invention has the advantages of short work procedure flow, strong pertinence, high efficiency, lower cost, reasonable structure, convenience in operation and easiness in large-area popularization and use.
