The invention belongs to the technical field of activated carbon, and particularly relates to a peanut shell activated carbon for removing toxins in peanut oil and a preparation method thereof. The peanut shell activated carbon is prepared by carrying out pretreatment, extrusion molding, carbonization and activation on peanut shells. The preparation method comprises the following steps: pretreatment: carrying out hydrothermal treatment on the peanut shells, and pulverizing; extrusion molding: carrying out pressure molding with a granulator to obtain cylindrical granules of which the diameters are 4-8 mm and the lengths are 10-20 mm; heating, cooling in the absence of oxygen, crushing and screening to control the granule diameters at 1-3 mm; and introducing isothermal superheated vapor, storing in a sealed environment, and cooling to obtain the finished product. The activated carbon is prepared from the peanut shells which are accessible raw materials, thereby implementing utilization of waste peanut shells; and the obtained peanut shell activated carbon has the advantages of large specific area and small pore size, can simultaneously adsorb benzopyrene, aflatoxin and other harmful substances, and can prevent the peanut oil from oxidative rancidity.

A grounding control lock is arranged on the grounding connecting piece, a rotating shaft of the grounding control lock can rotated to be switched between an unlocking position and a locking position, an unlocking key can be pulled out only in the unlocking position, and the rotating shaft of the grounding control lock is connected with a grounding control hook. A spring is arranged between the pressure control rod and the grounding connecting piece, a three-phase-interlocking locking device is arranged on the grounding rod, and the interlocking key further can open or lock the three-phase-interlocking locking device. The grounding sequence lock has the advantages of being convenient to install, flexible in use and capable of controlling and guiding a grounding operator to accurately perform grounding operation, eliminates potential safety hazards, meets sequence requirements for assembling and disassembling the grounding wire through safe technical measures and meets needs for site operation.

The invention discloses a brewing method of mulberry wine, comprising the following steps: (1) treatment of mulberry leaves: including drying and crushing of mulberry leaves; (2) fermentation of mulberry fruit wine: including alcoholic fermentation of mulberry fruit juice by using Saccharomyces cerevisiae (3) Maturation and aging: add the mulberry leaves obtained in step (1) during the process; the aging and aging include high-temperature aging and normal temperature aging, the temperature of the high-temperature aging is 60-70°C, and the temperature of the normal-temperature aging The temperature is 20-25°C; (4) post-processing: including clarification, freezing, filtering and filling of the liquor obtained in step (3). The invention utilizes the improvement of adding mulberry leaves after frost and ripening and aging to solve the problems of unstable quality and unclear style characteristics of the existing mulberry wine, and increases the types and contents of natural healthy active substances of the mulberry wine, so that the health care function is stronger.

The invention discloses a fertilizing method for reducing the cadmium content of leafy vegetables in an overproof cadmium vegetable plot, which comprises the following steps: (1) taking a carbonized rice husk as a base fertilizer, applying before the leafy vegetables are sowed and uniformly raking with soil or embedding the carbonized rice husk into a planting trench before the leafy vegetables are transplanted; and (2) taking an inorganic fertilizer as an additional fertilizer, and spray-applying the inorganic fertilizer rich in nitrogen, phosphorus and potassium taken as the additional fertilizer after the final singling or the survival of the leafy vegetables. In the step (1), 250-750 kg of carbonized rice husk is applied for each mu. In the step (2), the inorganic fertilizer is uniformly divided into 3 or 4 parts and is dissolved into water to be spray-applied, the inorganic fertilizer is sprayed for the first time after the final singling or the survival of the leafy vegetables, is sprayed once every 5-10 days and is totally sprayed for three or four times, and the inorganic fertilizer provides N5-15 kg, P2O51.6-4.0 kg and K2O55.0-15.0 kg for each mu. The fertilizing method has the benefit that as the carbonized rice husk and the inorganic fertilizer are applied together, the safe quality of the leafy vegetables is improved, and the content of Cd in the leafy vegetables is reduced.

The invention relates to an intelligent breeding control system and method based on video identification. The room environment control of a farm and the behavior monitoring early warning of pigs are realized. Core component comprise a GPU server group module and a core control panel module. A high definition camera module is used to collect video information, after the GPU server group module identifies breeding room environment abnormality and pig abnormality, the GPU server group module automatically analyzes abnormal data and sends data to an STM32 to carry out alarming and intelligent control decision making, then the regulation is carried out through the data collection input of various sensors and the data output of a corresponding controller, and at the same time, controlled data is continuously sent to a data center to form a closed loop control circuit. Compared with the prior art, the intelligent breeding control system and method have the advantages of the real-time monitoring of pig physical conditions and farm environment conditions, fast adjustment and control, and low control cost.

The invention provides a printing film-laminated metal plate and a production method thereof. The printing film-laminated metal plate comprises a metal substrate, a printing composite film and an inner film, wherein the metal substrate is positioned between the printing composite film and the inner film so as to form no-adhesive attachment; the printing composite film is formed by dry composition between an intaglio-printing film and a polyester film modified by isophthalic acid; one side of the intaglio-printing film with printing patterns is attached with the acid-modified polyester film, and one side of the intaglio-printing film attached with the metal substrate is the acid-modified polyester film; and the inner film is made of no-printing-pattern film or intaglio-printing film, and one side of the intaglio-printing film with the printing patterns is attached with the metal substrate. The invention also provides the production method of the printing film-laminated metal plate. The printing film-laminated metal plate provided by the invention has the advantages that the printed patterns are sealed between the film and the metal substrate, so that the safety of the printing film-laminated metal plate is obviously improved and the processing process is simplified.
