Method for preparing pesticide-removing fruit and vegetable cleaning agent based on shell powder

The invention belongs to the field of detergent compositions, and provides a method for preparing a pesticide-removing fruit and vegetable cleaning agent based on shell powder. The pesticide-removing fruit and vegetable cleaning agent is prepared from natural shell powder as a main raw material, and a natural adjuvant by the steps of preparation of micro/nano shell powder and addition of the natural adjuvant. The pesticide-removing fruit and vegetable cleaning agent is capable of effectively adsorbing and removing harmful residue matters such as pesticides and chemical fertilizers in the fruits and vegetables, not changing the properties of foods, and prolonging the quality guarantee period, and is safe, non-toxic, degradable, and suitable for cleaning of various fruits and vegetables; and the fruits and vegetables can be directly eaten after being cleaned. The pesticide-removing fruit and vegetable cleaning agent has good adsorptive property, bactericidal performance and the like, can play a good adsorption role in pesticide residues on the surfaces of the fruits and vegetables, is free of harm to a human body and the environment, and is capable of overcoming the defects of an existing cleaning agent in the aspects of non-degradation and chemical synthetic substance residue on the surfaces of the fruits and vegetables.

Forward osmosis membrane bioreactor with magnetic nanoparticles serving as driving liquid

The invention discloses a forward osmosis membrane bioreactor with magnetic nanoparticles serving as driving liquid and relates to a forward osmosis membrane bioreactor. The forward osmosis membrane bioreactor mainly solves the problems that existing forward osmosis membrane bioreactors uses inorganic salt as the driving liquid, and a salt solution osmoses into the bioreactor and has an inhibitory effect on microorganism, so that the sewage treatment effect is reduced. The bioreactor comprises a liquid storage pot, a water inlet pump, a first water inlet valve, an aerator pipe, a biological reaction tank, a mud valve, a forward osmosis membrane, a driving liquid tank, a second water inlet valve, a third water inlet valve, a first liquid storage tank, a second liquid storage tank, a first electromagnetic field, a second electromagnetic field, a first water drainage valve, a second water drainage valve, a first backflow valve, a second backflow valve and a pump, wherein the liquid storage tank is connected with the biological reaction tank through the water inlet pump and the first water inlet valve, the aerator pipe and the mud valve are arranged on the biological reaction tank, the forward osmosis membrane is connected between the biological reaction tank and the driving liquid, and the driving liquid is filled in the driving liquid tank. The forward osmosis membrane bioreactor is applied to the field of sewage treatment.

Debris flow guiding slot based on step anti-erosion toothed sill group and application thereof

The invention discloses a debris flow guiding slot based on a step anti-erosion toothed sill group and the application thereof. The slot structurally comprises beam side walls and a step anti-erosion toothed sill group which is arranged between the walls, connected and matched with the same; the step anti-erosion toothed sill group comprises a plurality of anti-erosion toothed sills with a certain depth, and every two steps are distributed by a certain spacing; the two anti-erosion toothed sills are symmetrically distributed on the left side and the right side relative to the centerline of the guiding slot between the beam side walls to commonly form one step of the step anti-erosion toothed sill group; and the width D of the debris flow guiding slot is more than two times of horizontal length B of the anti-erosion toothed sills in the vertical direction of the beam side walls. Compared with the prior art, the invention can meet the requirements on the excretion of fluid with quite great changes from thin debris flow to mountain flood, can fully keep the up and down relationship of aquatic organisms in a gully, is beneficial to the ecological restoration a channel, can fully guarantee the stability of the beam side walls, is not easy to have debris flow deposition under the circumstance that the gradient of the gully is quite small, and is beneficial to long-termed operation.

Oil-smoke agent of microbial pesticide of bacillus and preparation method thereof

The invention relates to an oil-smoke agent of a microbial pesticide of bacillus and a preparation method thereof. The oil-smoke agent is a product prepared by the steps of: shearing and uniformly dispersing bacillus thuringiensis subsp kurstaki raw powder, a dispersing agent, a thickening agent, an emulsifying agent, an antifreezing agent and a solvent; and then grounding by a grinder until 90 percent of materials achieve fineness less than 5 micrometers; an finally uniformly stirring. When in use, the oil-smoke agent is quantificationally delivered into a fuming pipe to be mixed with high-temperature high-speed air flows into micrometer-grade droplets which are sprayed out by a smoke sprayer; and the micrometer-grade droplets are uniformly precipitated in different direction of each position of a target, thereby the oil-smoke agent has good precipitation effect and high preventing and curing efficiency; in addition, the oil-smoke agent has strong adhering force for the target, high rain washing resisting capacity, high affinity between the droplets and the target, longer duration, economic medication, convenient use, quick effect, sprays without adding water and is especially suitable for the forest pest control of forest zones with inconvenient traffic, few water source, precipitous hillsides and high woods and the forest pest control of closed conditions, i.e. greenhouses,storages, orchards, and the like.

Electromagnetic stirring analyzing and constructing method based on electrical magnesite smelting furnace

The invention relates to an electromagnetic stirring analyzing and constructing method based on an electrical magnesite smelting furnace. The electromagnetic stirring analyzing and constructing method includes the following steps that an electromagnetic field space is dispersed into grids of 50*50*50, digital values of discrete points are used for simulating actual electromagnetic field distribution to obtain digital value distribution of electric-field vectors in the x, y and z directions during 100-200 step iteration; an electromagnetic stirrer modeled according to the Maxwell equation to obtain the relation between magnetic induction intensity and electromagnetic stirring; when the electromagnetic stirrer is simulated, the magnitude of electromagnetic force is determined by magnetic induction intensity and induction currents together; under the action of the optimal stirring frequency of the electromagnetic stirrer, conducting magnesium oxide solution rotates after obtaining lorentz force. Materials of the electrical magnesite smelting furnace are stirred through an electromagnetic field, the strong flushing effect on the front edge of an interface is achieved, heat transfer and mass transfer in the crystallization process can be effectively changed, pollution to melt in the stirring process is avoided, and no quality difference caused by artificial factors exists in electromagnetic stirring.
