The invention relates to a method for removing heavy metals in traditional Chinese medicine by using a zeolite molecular sieve membrane, which comprises the following steps: (1) cleaning the surface of a porous carrier, and coating a seed crystal suspension on the surface of the porous carrier; After drying at a certain temperature, the porous carrier is placed in the crystal growth solution until the seed crystals on the surface of the porous carrier are produced into a film to obtain a zeolite molecular sieve membrane; (2) one side of the zeolite molecular sieve membrane prepared in step (1) The traditional Chinese medicine extract is circulated, and the complexing agent solution is circulated on the other side of the zeolite molecular sieve membrane to remove heavy metals in the traditional Chinese medicine extract. Compared with the prior art, the present invention has less adsorption to the active ingredients of traditional Chinese medicines, has selectivity to heavy metal ions, and has low cost, and adopts a continuous production process, which is beneficial to popularization and use of the technology.

Urease-producing microbes including Sporosarcina antarctica U R 5 3, Sporosarcina koreensis UR47, Sporosarcina sp. UR31 and Bacillus lentus UR41 were preserved in China General Microbiological Culture Collection Center on March 16, 2012, with the preservation numbers of CGMCC No.5916, CGMCC No.5915, CGMCC No.5913 and CGMCC No.5914 respectively. The method for preparing high-strength microbial mortar by using the urease-producing microbes comprises the following steps of: carrying out fermentation culture on the above four microbes and microbes including Sporosarcina pasteurii and Terrabacter tumescens in a fermentation culture medium to obtain a bacterial solution; and filling the bacterial solution, a fixative solution and a gelling solution into a sand particle system in batches to form microbial mortar of which the highest strength can reach 55MPa. The mechanical properties of the microbial mortar are superior to those of a cement base material; compared with a cement lime material with equivalent strength, the microbial mortar is higher in splitting tensile strength; the rigidity of the microbial mortar is similar to that of cement lime mixed mortar but far smaller than that of concrete; the fatigue load tolerance and cyclic loading capacity of the microbial mortar are higher than those of the cement base material; and an artificial sandstone is an inorganic material, and is not easy to age like organic materials including epoxy resin and the like.

The present invention relates to a clamp used for at least one board component, comprising: a first clamp part and a second clamp part, wherein the clamp parts are mutually adjustable relatively between an open position and a clamping position used for the board component; and at least one elastic body moulding part arranged between the two clamp parts, wherein the elastic body moulding part comprises an area which has a U-shaped cross section and is used for peripheral embedding board components. According to the clamp of the present invention, the elastic body moulding part has a clamping section, when the clamp is in the clamping position, the clamping section is clamped between the two clamp parts.
