The invention provides a photocatalyst capable of utilizing not only an ultraviolet light, but also a visible light, to use the photocatalyst in the decomposition treatment of a harmful chemical in a gas phase or a liquid phase, and to provide a means for converting a harmful material into a harmless one by the use of the photocatalyst. A photocatalyst which comprises a composite oxide semiconductor represented by the general formula: BaBixOy [wherein x and y are 0.5 < x <2, and 2.5 < y < 4] as a catalyst component; and the above subject can be solved using the photocatalyst.

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 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. The invention also discloses the preparation method of the vaccine, the preparation process is simple and the use is safe.
