The invention relates to an artificial optimized culture method for sea squirts, microalgae and stichopus japonicus. The artificial optimized culture method for sea squirts, microalgae and stichopus japonicus is a bio-remediation technology for realizing self-purification of a culture water body and a sustainable marine product culturing method by utilizing a biological mutual benefit mechanism of a seawater polyculture system. The bait microalgae are inoculated in culture seawater; and the stichopus japonicus and the sea squirts are put into the culture water body with increased microalgae biomass. The inorganic nutritive salt in the seawater is converted into the microalgae biomass through the bioconversion of the microalgae so as to provide abundant bait for cultured organisms and simultaneously increase the concentration of dissolved oxygen in the water body. The sea squirts filtrate a large amount of sea water to remove grains and excess microalgae in the water body and settle a large quantity of aqueous layer particulate organic matters into a substrate in the form of feces and false faces. The demersal stichopus japonicus with a detritus food habit ingest the organic debris, benthic diatoms and microorganisms in the substrate so as to improve a substrate environment and reduce water body pollution. The artificial optimized culture method for sea squirts, microalgae and stichopus japonicus utilizes the polyculture system to promote the culture proliferation of the stichopus japonicus, carry out the self-purification and remediation of the culture water body, and realize the sustainable development of stichopus japonicus culture industry.

The invention discloses a magnetorheological damper piston assembly with a sedimentation active dispersion device, which includes a working cylinder, a piston rod and a piston assembly; the working cylinder is equipped with magnetorheological fluid; the upper end of the piston rod is inserted into Inside the working cylinder, the part where the lower end passes through the working cylinder is provided with an oil seal; the piston assembly includes a rotor, a stator, a top cover and a bottom cover; the outer circumferential wall of the rotor is provided with spiral ribs; the rotor The stator is loosely sleeved on the piston rod and located inside the working cylinder; the stator is sleeved on the rotor and located inside the working cylinder; a damping gap is formed between the stator and the rotor; the top cover is sleeved on the piston rod and located inside the working cylinder inside; the bottom cover is located in the working cylinder; the present invention causes the magnetorheological fluid to rotate and flow axially in the working cylinder through the damping gap through the rotation of the spiral ribs on the rotor, which not only realizes that the magnetorheological fluid settles after The redispersion of the magneto-rheological damper also helps the energy recovery of the magneto-rheological damper during normal operation.

The invention provides a method for removing a conductive layer containing a carbon conductive material from a Ti-made fuel battery separation plate while inhibit loss of a substrate that is Ti material. The Ti-made fuel battery separation plate of the invention comprises: a conductive layer which contains the carbon conductive material and is formed on the substrate made of pure titanium or titanium alloys, and an intermediate layer which contains titanium carbide and is formed between substrate and the conductive layer; and the method is used for removing the conductive layer from the Ti-made fuel battery separation plate. The method is characterized by dipping the Ti-made fuel battery separation plate in a water solution containing any one of nitric acid and hydrogen peroxide, or in a water solution containing both of nitric acid and hydrogen peroxide.

The invention belongs to the field of photocatalysis, in particular to a preparation method of a graphite-type carbon nitride composite nickel ferrite magnetic photocatalysis material. The magnetic nickel ferrite is bound to graphite carbon nitride by chemical adsorption method, wherein the mass ratio of graphite carbon nitride and nickel ferrite is 1:5~1:25, and the synthesis steps are as follows: Nitriding with a certain mass ratio Add carbon and nickel ferrite to anhydrous ethanol to disperse and stir for a period of time and then heat treatment at a certain temperature. The catalyst prepared by the invention has good magnetic properties, dispersibility and stability, and can still maintain high catalytic activity after five photodegradation cycle experiments. The g-C3N4 / NiFe2O4 composite photocatalyst is excited under visible light to generate photoinduced electrons and holes, and interacts with hydrogen peroxide to undergo a photo-Fenton reaction to achieve efficient degradation of methylene blue.
