Abstract: The present invention discloses a novel hydrophilic and compressible aerogel as draw agent for purification water in forward osmosis (FO), which belongs to environmental pollution control engineering technical field. The improved performances are obtained by optimizing regeneration process of drawing and producing water by using this aerogel as a draw agent in FO technology. Herein, the aerogel complete avoid the draw solution's reverse diffusion and maintain a higher water flux that compensates for its structure characteristics. Moreover, the regeneration of the draw agent and production water should be accomplished through human compression without a complicated physical and chemical method. Simultaneously, this draw agent presents other advantages of wide raw material sources, low cost, wild preparation process, low poison and good film compatibility.

Abstract: A kind of sawtooth structure with reversed cutting function and its drill series are specifically fitted for drilling carbon fiber reinforced polymers (CFRP). The sawtooth structure is constructed by sawteeth and grooves located on the cutting edges of drill. And the sawtooth structure is helically arranged with a large helix angle around the axis of the drill. It can be divided into left-hand sawtooth structure and right-hand sawtooth structure by the helix angle. The bottom edges of the left-hand sawtooth function as cutting edges, and the rake angles are positive, while the top edges of the right-hand sawtooth are ground as positive rake angles. The sawtooth structure can be applied into multiple drilling tools, which proves to be universal. And it can effectively reduce delamination at both hole entry and hole exit as well as burrs defects. The series of drilling tools are double point angle drill, twist drill and stepped drill with sawtooth structure on the cutting edges. And such forms of drilling tools can achieve hole drilling of CFRP with minimum drilling defects. The drilling performance of the tools is thus improved to a great extent, and the tool life is extended while maintaining low usage costs.

Abstract: A self-anchored piling sediment sampler belongs to the technical fields of environmental monitoring, environmental government and sediment sample collection. The sampler is mainly composed of a sampling tube mechanism, an anchor rack mechanism and a cable. A drainer is designed to realize automatic drainage and air seal, so that an anchor socket can form a good anchoring condition with sediments during collection, thereby providing a stable sampling condition in cooperation with adjustable self gravity. The drainer is also applied in the sampling tube mechanism, thereby facilitating collection and seal of sediment samples. At the end of sampling, a water injector can eliminate suction force of the sediments and alleviate resistance in a lifting process. The cable is fixed to an outer sampling tube by fixed pulleys A, clamping hooks and fixed pulleys B placed on fixing rods so as to realize the conversion of the pulling force into the pressure on the sampling tube and provide sampling power. Thus, the collection of layered sediment samples is realized. The collection device has the features of light weight, high efficiency and good fidelity, and is especially suitable for collection of layered sediments of such water areas as reservoirs and the like with great water depth and soft bottom material.
