A preparation method for garbage enzyme comprises the following steps: putting fruits and / or vegetable, as well as water and saccharides into a closed container according to a ratio, fermenting for 3 to 6 moths, filtering, and taking clear liquid after the filtering, thus obtaining the garbage enzyme, wherein the garbage enzyme is formed by mixing and fermenting according to the volume ratio that the fruits and / or the vegetables : the water : the saccharides is equal to 1: (2 to 4) : (8 to 12). A preparation method for an algal bloom inhibitor comprises the following step: adding water to dilute the garbage enzyme prepared by the preparation method for the garbage enzyme, thus obtaining the algal bloom inhibitor. The algal bloom inhibitor has a remarkable effect of inhibiting alga growth, contributes to aquatic ecological environment purification and water body self-recovery, and has a perfect improving effect on water quality; the preparation methods for the garbage enzyme and the algal bloom inhibitor are simple, low in cost, easy for industrialized operation, and capable of avoiding secondary pollution.

The application of an environmentally friendly enzyme in the prevention and control of algal blooms in lakes. Wherein, the environmental protection enzyme has the effect of inhibiting the abnormal increase of TN caused by algae proliferation; or, the environmental protection enzyme has the effect of inhibiting the abnormal increase of pH caused by algae proliferation; or, the environmental protection enzyme has Improve the water quality of the water environment. And an application of an environment-friendly enzyme in the preparation of an algal bloom inhibitor, wherein the environment-friendly enzyme is prepared by putting fruits and / or vegetables, water, and carbohydrates in proportion to fermentation in a closed container. The algae are Microcystis aeruginosa, Scenedesmus tetracerus and / or Navicula rhinocephalum. The present invention finds that the environmentally friendly enzyme is used for the first time to prevent and control the harm of algal blooms in lakes, and has a significant effect on inhibiting the growth of algae; in addition, the preparation method of the environmentally friendly enzyme / algal bloom inhibitor is simple, low in cost, easy to industrialized operation, and can also avoid the occurrence of Secondary pollution.

The invention discloses a spin-type large-rotation spray dust-reduction spray rack, which includes a shaft tube. One end of the shaft tube is perpendicular to the shaft tube and a support tube that can rotate at the end of the shaft tube is installed. The support tube is arranged symmetrically with respect to the shaft tube. A plurality of spray heads are distributed on the support tube, wherein the spray heads located at both ends of the support tube face opposite. Use this device technology to spray and reduce dust in dust-producing places, quickly extinguish the source of dust generation, control and prevent dust from spreading and polluting the environment; in the area where the installation is controlled, it can humidify the air in the regional environment to help air purification; due to the device The coverage area is large, and the spray fluid has an auxiliary cooling effect in the installation control area in hot summer; the installation method is flexible, and can be divided into indoor installation and open-air installation, without affecting ground traffic; reasonable structure, strong structural strength, strong wind resistance, open-air installation design There are lightning protection devices.

The invention discloses a novel faucet, and belongs to the technical field of bathroom accessories. By adoption of the novel faucet, the problem that a water-purification filter element assembly of anexisting temperature-adjustable faucet is inconvenient to install is solved. The novel faucet is technologically characterized in that the novel faucet comprises a faucet body and a ceramic valve element mounted in the faucet body. A hot water port and a cold water port are formed in the bottom of the ceramic valve element. The faucet body is connected with a hot water pipe communicating with thehot water port and a cold water pipe communicating with the cold water pipe. The faucet body is provided with a filter piece, and the filter piece is located below the ceramic filter element and abuts against the bottom of the ceramic valve element in a sealing mode. The filter piece is provided with a hot water channel communicating between the hot water port and the hot water pipe and a cold water channel communicating between the cold water port and the cold water pipe. Filter assemblies are arranged in the hot water channel and the cold water channel. The novel faucet is provided with thefilter piece which is convenient to mount and dismount, so that the quality of water in the novel faucet is improved, and mounting and dismounting of the novel faucet are facilitated.

The invention discloses a method for improving an aquaculture environment. The method for improving the aquaculture environment mainly comprises the three steps of cleaning the bottom of a pond and using electrified water to conduct sterilization treatment, making the bottom of the pond paved with a pond bottom material and spraying expanded vermiculite suspension liquid, throwing composite microorganisms and composite active enzyme after water is injected, the three steps are indispensable, and cannot be reversed, every step goes forward one by one, all the steps are are linked with one another, and therefore the aquaculture environment is improved.

The invention relates to an inelastic lace trimming and a production method of the inelastic lace trimming. A lace layer is combined on inelastic fabric and is formed by weaving polyester and nylon composite yarn and modified nylon yarn, and the mass ratio of the polyester and nylon composite yarn to the modified nylon yarn is 1:1. The production technology is simple in process, and large-scale industrial production can be carried out. The polyester and nylon composite yarn has the weaving and dyeing performance of both polyester and nylon and can be twisted together for weaving production, and thus the polyester and nylon composite yarn not only can show special texture and metal brilliance of metal wires but also is softer and comfortable than the metal wires. Meanwhile, the hard texture of the inelastic trimming can be shown better, and the lace trimming is inelastic fabric and can be widely applied.

The invention provides an additive for cooling water and antifreeze of a radiator for improving performance of conveying equipment, and antifreeze prepared by adding the additive. The additive contains tourmaline powder, medical stone, germanium and rare earth metals such as lanthanum, cerium, neodymium etc., hydrogen is produced via lanthanum (La), cerium (Ce) and neodymium (Nd) with hot water in cooled one, the produced hydrogen is stored in iron-titanium alloy, and the stored hydrogen is dispersed again with a function of power storage by the circulation. The invention is capable of savingfuels and reducing purged gas. Furthermore, the invention makes for cleaning up environment, decreasing noises, improving effect of combustion ratio and implementing the performances for maintaining electrostatic pressure and reducing static electricity, having a function of cleaning internal air of vehicles during a process of oxidizing and restoring repeatedly.

The present invention discloses a porcine CSFV-PCV duplex DNA vaccine, comprising an expression vector into which a gene E2 encoding CSFV structural protein E2, a gene Erns encoding CSFV structural protein Erns, and a PCV-2 immune protein Cap are inserted The gene Cap and the gene Rep encoding the PCV-1Rep protein. The vaccine can express E2, Erns, Cap and Rep proteins in vivo by immunizing animals by subcutaneous injection, and induce the body to produce higher levels of antibodies, thereby preventing and controlling the infection and prevalence of CSFV and / or PCV‑2 and Mixed cross-infection avoids the occurrence of other diseases caused by mixed infection of CSFV and PCV‑2; and the vaccine helps to purify CSFV and PCV‑2 strains in pig farms.
