This invention discloses a method for separating fluorosilicic acid and hydrofluoric acid using an anion exchange membrane, comprising the following steps: adding a flocculant to a fluorosilicic acid-hydrofluoric acid mixture, aging it, then adding a desulfurizing agent to carry out a desulfurization reaction to obtain a mixed solution, adding the mixed solution to the feed side of an anion exchange membrane for membrane separation, and obtaining a hydrofluoric acid solution with a mass concentration of 2-30% on the clear water side after separation. This invention uses a flocculant to rapidly settle solids such as sodium fluorosilicate and potassium fluorosilicate in the fluorosilicic acid-hydrofluoric acid mixture, uses a desulfurizing agent to remove sulfuric acid, and then uses an anion exchange membrane to effectively separate fluorosilicic acid and hydrofluoric acid in the fluorosilicic acid-hydrofluoric acid mixed solution. The hydrofluoric acid separated by membrane separation has high purity and high output value, increases the utilization rate of by-product hydrofluoric acid, and reduces costs.

This invention provides a method and apparatus for generating digital SMS content, relating to the field of data processing technology. The method involves obtaining first historical marketing SMS information from a first merchant; obtaining first SMS content elements and second SMS content elements based on the first historical marketing SMS information; obtaining a first degree of influence of the first SMS content elements on the marketing effect of the first merchant and a second degree of influence of the second SMS content elements on the marketing effect of the first merchant; determining whether both the first degree of influence and the second degree of influence exceed a first preset threshold; when the first degree of influence and / or the second degree of influence exceed the first preset threshold, obtaining a first SMS content template based on the first SMS content elements and / or the second SMS content elements; and obtaining a first optimal SMS content based on the first merchant's first marketing task and the first SMS content template. This achieves the technical effects of improving readability and conversion rates, realizing precise marketing strategies, and increasing output value.

A method for transforming saline-alkali land, in the field of land improvement technology, includes the preparation of wood ash granules, the preparation of mixed organic matter granules, granule mixing, and precise determination of application amount. It provides a novel and comprehensive method for transforming saline-alkali land by utilizing the resources of waste from biomass power plants and combining it with a specific organic matter formula to reduce soil alkalinity and significantly improve soil permeability, water retention, and fertility, thereby transforming saline-alkali land into fertile land suitable for crop growth.

The present application relates to solid waste resource comprehensive utilization technical field, disclose a kind of calcination desulfurization-electric furnace reduction processing laterite nickel ore acid leaching residue method, comprising the following steps: S1.laterite nickel ore acid leaching residue and auxiliary material are used as raw material, oxygen-enriched air and first fuel are introduced into raw material to carry out calcination desulfurization, obtain sulfur-containing flue gas and desulfurization hot slag;S2.desulfurization hot slag obtained in S1 with second reducing agent is directly put into electric furnace and is reduced smelting, obtain molten iron, reduction smelting flue gas and reduction smelting slag, desulfurizer is added to the molten iron and is desulfurized, and iron ingot is prepared;S3.reduction smelting slag is obtained after water quenching treatment water quenching slag, the water quenching slag is mixed with excitation agent, after drying, grinding, obtain active micro-powder material.This method realizes laterite nickel ore acid leaching residue full resource comprehensive utilization, fully recycles residual valuable metal including Fe, Ni, realizes the full development and utilization of valuable metal, sulfur, tailings and other slag components.

The application discloses a configuration method for pollination trees in Gleditsia sinensis plantations and belongs to the technical field of Gleditsia sinensis planting. In the configuration method, the planting quantity ratio of Gleditsia sinensis female plants, Gleditsia sinensis var. cathayensis male plants and Gleditsia delavayi male plants is set to 26-30:1-3:1-2, and the planting quantity of the Gleditsia sinensis var. cathayensis male plants is greater than that of the Gleditsia delavayi male plants. By introducing the Gleditsia sinensis var. cathayensis with early flowering period and the Gleditsia delavayi with late flowering period to perform interspecific cross-pollination, the application realizes the continuation and coverage of the flowering period, guarantees the continuous supply of male pollen in the whole female flower opening period, greatly improves the fruit setting rate and yield of the Gleditsia sinensis, and significantly improves the pod and seed quality of the Gleditsia sinensis var. cathayensis and the Gleditsia delavayi, including the significant improvement of saponins, amino acids, pectin and total sugar components. It can be seen that the application significantly improves the production efficiency of the Gleditsia sinensis plantations.

A corn and chive composite planting method belongs to the technical field of planting methods. The problems that water and soil loss is serious, biodiversity is reduced, and the income increasing pressure of farmers is large in existing corn single cropping are solved. According to the method, after previous crops are harvested, soil is subjected to deep ploughing or deep scarification in autumn, and fertilization is conducted; in spring of the second year, when the soil is thawed by 15-30 cm, pulp jacking and ridging are carried out, an allium fistulosum planting belt is arranged every 6-8 rows of corn planting belts, and the ratio of the corn planting belts to the allium fistulosum planting belt is (3.6-4.8 m): (1.2-1.5 m); planting the chive as soon as possible after the soil is completely unfrozen, ditching or digging holes in a chive planting belt, planting a cluster of division seedlings of the chive in each hole, treading after planting, and thoroughly watering for fixing roots; corn sowing is conducted 7-10 days after field planting of the allium fistulosum and when the ground temperature is stabilized to be 8 DEG C; and harvesting after the corn and the chive are mature. The method has the advantages of efficient utilization of resources, complementation of ecological functions, superposition of economic benefits and exertion of regional advantages.
