This invention belongs to the field of biological agents for aquaculture, and discloses a compound biological pond-cleaning agent containing tea saponin and its preparation method. The compound biological pond-cleaning agent of this invention comprises the following components by weight: 3-10 parts tea saponin, 60-70 parts roe beetle root powder, 10-20 parts Buddleja officinalis, 5-10 parts compound microbial powder, 3-8 parts adjuvants, and 10-20 parts carrier; the adjuvant is a mixture of sodium lignin sulfonate and sodium dodecylbenzene sulfonate; the compound microbial powder is a mixture of Bacillus subtilis and photosynthetic bacteria; and the carrier is diatomaceous earth. This invention combines three natural active ingredients—tea saponin, roe beetle root powder, and Buddleja officinalis—with suitable adjuvants and a carrier, which can expand the pond-cleaning range and has good killing or inhibitory effects on harmful organisms such as wild fish, shrimp, crabs, and snails, as well as various pathogens. The pond-cleaning is thorough, and the raw materials are easily degradable, leaving no residue. It is environmentally friendly and has a long-lasting effect, which is of great significance for promoting the green and sustainable development of aquaculture.

The present application relates to a kind of gel microspheres adsorption and ultrasonic combined management brown cystosphaera globosa red tide method and gel microspheres regeneration method in red tide control technical field, wherein the gel microspheres adsorption and ultrasonic combined management brown cystosphaera globosa red tide method, first, gel microspheres are prepared, then gel microspheres are loaded in filter bag and ultrasonic device is combined to manage the brown cystosphaera globosa red tide in water area.In addition, the regeneration method of gel microspheres is that the gel microspheres after being adsorbed and managed are recycled for regeneration and reuse, and the effect of removing brown cystosphaera globosa is still good.The management method of brown cystosphaera globosa red tide in the present application, by the adsorption of gel microspheres and the auxiliary effect of ultrasonic, not only can remove brown cystosphaera globosa cell in water body efficiently, but also avoid the release of intracellular hemolytic toxin;Meanwhile, it also has good elimination effect on phosphate in water body, avoids the recovery of red tide algal cell and reoccurrence.

The present application relates to dam protection field, disclose a kind of termite protection system for dam, including dam, multiple detection tubes are vertically installed on the dam, and the top of each detection tube is equipped with a wire laying device, the wire laying device includes support frame, rotatably mounted wire roller on support frame and motor for driving wire roller rotation, wire roller is wound with guy wire, and the extension end of guy wire is hoisted with counterweight, installation groove is processed on the counterweight, and detachable detection device, pest control device and grouting device are installed in the installation groove on adjacent wire laying device.The present application installs multiple detection tubes on dam, and installs wire laying device on detection tube, uses wire laying device, and successively puts detection device, pest control device and grouting device into detection tube in sequence, can be used to detect termite nest in dam, and is convenient for fixed-point killing to termite, to ensure the killing efficiency of termite, to ensure the safety of reservoir.
