The invention discloses a multiple-effect biological solid catalyst used for reclaimed water treatment, consisting of three layers of coatings; the innermost layer is an activated nanometer tourmalinematerial, the middle layer is hydroxylapatite, the outer layer is active carbon powder and the three layers of coating of the solid catalyst form gradient porous channels from nanometer level to micron level from inside to outside. A preparation method thereof comprises the following steps of: controlling humidity and rotating speed, and molding the selected bentonite by adopting a rotary method;injecting the activated tourmaline powders into a rotary table, regulating humidity and rotating speed, then finishing the innermost layer coating after operation and calcining; exchanging the coating materials into hydroxylapatite, regulating and controlling humidity and rotating speed, finishing the middle layer coating after operation and calcining; exchanging the coating materials into activecarbon powder, regulating and controlling humidity and rotating speed, finishing the outer layer coating after operation and drying and obtaining the finished product of the solid catalyst. The multiple-effect biological solid catalyst can improve the traditional biochemical efficiency by 20 to 30 percent and reduce the foul odour (taking hydrogen sulfide as index) by 50 to 60 percent.

A compound probiotic oligosaccharide fruit feed additive and a method for preparing and using the same, comprising the following fermented products in parts by weight: 500-800 parts of crushed fresh fruits such as fruits and pears, 100-200 parts of adsorption auxiliary materials such as straw powder and cake meal, compound 2-10 servings of probiotics, 0.001-0.01 servings of oligosaccharides, and 1-5 servings of edible salt. Among them, fresh fruit crushed and adsorption auxiliary materials are simple and easy to obtain, which reduces the manufacturing cost. The added compound probiotics can effectively regulate the function of the intestinal flora of livestock and poultry, and can also replace some antibiotics to reduce drug residues. By adding this compound probiotic oligosaccharide fruit feed additive to the feed, it can effectively improve the growth performance of livestock and poultry, improve the meat quality of livestock and poultry, and improve the environmental sanitation of livestock and poultry pens and reduce environmental pollution. Economic benefits, suitable for widespread promotion.

The invention discloses a pentamethylenediamine succinate and its crystal, and a preparation method thereof. The pentamethylenediamine succinate is a salt in a solid state at normal temperature formed by combining pentamethylenediamine divalent cations and succinic acid dianions in a molar ratio of 1:1. Its crystal structure is C 9 h 20 N 2 o 4 , Monoclinic system, P2(1) / c space group, α=90.00°, β=107.384(3)°, γ=90.00°, the minimum number of asymmetric units in the unit cell Z=4. The preparation method comprises: crystallizing pentamethylenediamine succinate from a solution containing dissolved pentamethylenediamine and succinic acid, separating the crystals from the solution, and drying the separated crystals.

The invention relates to a cofferdam device for controlling a landfill garbage working plane. The cofferdam device comprises vertical supporting columns and transverse supporting columns. The vertical supporting columns and the transverse supporting columns are welded into a plurality of frames which are in a shape like the Chinese character 'mu', the surfaces of the frames are welded with baffles, the parts, close to the ground, of the baffles are tapping sections with the surfaces provided with water leakage holes, sewage grooves are formed below the tapping sections are respectively, the sewage grooves are grooves made of plastic plates, holes are formed in the grooves and are connected with pipes for draining waste water, the outside portions of the frames are supported by supporting rods made of metal materials, each supporting rod comprises a supporting rod body perpendicular to the ground, the exteriors of the supporting rod bodies perpendicular to the ground are welded with inclined supporting rods inserted into the ground in an inclined mode, and aluminum plastic panels are arranged on the outer sides of the inclined supporting rods to separate the whole cofferdam device and the garbage working plane from the outside. The garbage stack slope can be made to conform to the proportion of 1:1.5, the working exposed area can be obviously reduced, the working plane can be effectively controlled, the optimization of rain and dirt diverting can be achieved by combining a mulching film, and the appearance is clean in the garbage operation process.

The invention discloses a baby black Guinea pig breeding method comprising the following steps: step A, choosing a breeding box of 0.5-1 square meters, disinfecting the breeding box, exposing the breeding box to the sun, controlling the temperature of the breeding box at 18-25 DEG C and the relative humidity at 40-50%, and setting aside for later use; step B, feeding a baby black Guinea pig with a first feed three times a day and a first green fodder once a day in the period from the time of weaning to the age of 20 days of the baby black Guinea pig; and step C, feeding the baby black Guinea pig with a second feed three times a day and a second green fodder once a day and feeding the baby black Guinea pig with 5-10ml nutritive water every morning in the period from the age of 21 days to the age of 40 days, thus obtaining a robust adult black Guinea pig. By adopting the method, the immune power of baby black Guinea pigs can be enhanced, the growth of baby black Guinea pigs can be speeded up, the nutrition of black Guinea pig meat is more comprehensive, and the economic benefit of black Guinea pigs is improved.

The invention relates to a preparation technology of a microorganism straw feed. The preparation technology of the microorganism straw feed comprises the following steps: preparing a microorganism bacterium agent, removing impurities of straw raw materials, crushing the straw raw materials without impurities, adding the microorganism bacterium agent, stirring the microorganism bacterium agent and the crushed straw raw materials without the impurities so as to obtain a mixture, sealing the mixture, and fermenting the sealed mixture so as to obtain the microorganism straw feed. The straw raw materials of the microorganism straw feed are wide in sources, and fresh straws of which the water content is 12-78%, naturally dried straws and dried mildewed straws can be processed; the preparation method is simple and clean, the cost is low, products can be stored for 6-12 months, and the products can be transported for a long distance; the straw feed disclosed by the invention has the effects of promoting livestock to grow, enhancing the disease resistance of the livestock, relieving the odor of excrement in breeding houses, and improving the quality of livestock meat.
