The invention provides an ultrasonic-assisted mineralized refuse participating method for treating organic waste water by homogeneous Fenton. The method includes the following steps of (1) directly adding a ferrous ion salt, hydrogen peroxide (H2O2) and mineralized refuse powders into the waste water, and adjusting the potential of hydrogen (pH) value to 5 to 6; and (2) adding the waste water into an ultrasonic reactor, performing an ultrasonic action for 1 to 5 minutes, then performing a purification treatment, simultaneously stirring, precipitating after reaction, and performing a solid-liquid separation to complete the waste water treatment. The ultrasonic-assisted mineralized refuse participating method for treating the organic waste water by the homogeneous Fenton has the advantages that cumbersome synthetic steps of prior load type iron oxide catalysts are omitted, besides, the porosity of the mineralized refuse is high, the specific surface area is large, the mineralized refuse is low in cost and easy to obtain, a cation exchange characteristic of the mineralized refuse is utilized, iron ions can be exchanged to the surface of the mineralized refuse while the iron ions exert an catalytic action, the iron ions are prevented from losing, the iron ions in water are prevented from being polluted, the possibility of reutilization is improved, and the reaction can be completed within a short time by the aid of a dispersing function and a cavitation characteristic of ultrasonic waves.

The invention discloses a micro-reactor system with a pulse diameter-variable microstructure and relates to the technical field of micro-reactors.The system comprises a raw material tank, a metering pump, a pressure gauge, a micro-reactor, a heat exchanger and a product collecting tank.The micro-reactor system has the advantages that the core unit of the system is the micro-channel structure inside the micro-reactor, the micro-channel structure can well enhance the material mixing effect, materials from two feeding inlets simultaneously enter a micro-channel pipeline with the pulse diameter-variable microstructure, the pulse diameter-variable microstructure allows the system to be in an evenly dispersing state after the high-speed cross collision of fluid, the fluid then enters the micro-channel with the continuous variable diameters, and the mixing effect of separation first and then combination is achieved; the channel of the reactor is high in heat exchanging ability, the system temperature is allowed to stay at the temperature beneficial to reaction, and the system is mild in reaction condition, short in reaction time, high in raw material utilization rate, capable of achieving effective control of a reaction process, safe and stable, capable of achieving continuous operation and high in production efficiency.

The invention aims to provide a stichopus japonicus and abalone integrated-breeding method. In other words, both abalone and stichopus japonicus are put into abalone breeding cages and are bred in a shallow sea raft mode, and the stichopus japonicus and abalone integrated-breeding method is free of pollution and ecological and environmentally friendly. According to the method, the stichopus japonicus is bred in abalone breeding cages, the characteristic of deposition feeding habits of the stichopus japonicus is fully utilized, feces of the abalone in the breeding cages are removed, and the pollution of the organic matter in the feces of the abalone to the seabed is reduced. Meanwhile, the stichopus japonicus feeds organic detritus, benthic diatom and the like which are attached on the breeding cages so that the breeding environment can be cleaned, and flow inside and outside the breeding cages is smooth.

The invention provides a modified hydrotalcite preparation method, which comprises: putting aluminum-magnesium hydrotalcite into a muffle furnace, heating to 480 DEG C at a heating rate of 5 DEG C.min<-1>, and roasting for 5 h; grinding, and screening with a 200-mesh sieve to obtain roasted modified hydrotalcite; and carrying out intercalation modification on the roasted modified hydrotalcite by using sodium dodecyl benzene sulfonate or diethyltriaminepentaacetic acid. According to the invention, the hydrotalcite is properly modified, so that the agglomeration can be reduced, and the dispersity is enhanced; and the interlayer ions are changed, so that the ion exchange reaction is promoted, and the high ion exchange capacity is achieved.
