Abstract
The invention discloses a production method of gypsum tailings compressed nutrient soil. The key point of the technical scheme is that the production method comprises the following steps: first, acidifying gypsum tailings and sludge; then, packaging into a finished product after carrying out stirring, compression and microwave low-temperature sterilization on ingredients of the gypsum tailings compressed nutrient soil. The gypsum tailings compressed nutrient soil is prepared from the following raw materials such as acidified gypsum tailings, acidified sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, hyperviscous attapulgite, biogas slurry, biogas residues, smashed plant fibers, expanded vermiculite, expanded perlite and super absorbent resin. The gypsum tailings compressed nutrient soil contains a plenty of nitrogen, phosphorus, potassium, organic matters and various microelements and can provide nutrient elements required by plant growth and reduce the damage on the plants caused by pathogenic bacteria and injurious insects, thereby facilitating normal growth and development of the plants and protecting the ecological environment. The production method of the gypsum tailings compressed nutrient soil is suitable for producing gypsum tailings compressed nutrient soil with different formulae.

Gypsum is oblique system mineral, main chemical compositions is the hydrate of calcium sulfate, natural dihydrate gypsum is called again plaster stone, through calcining, the levigate beta-type semi-hydrated gypsum that obtains, when we are gypsum reserves big country, be again the poor country of high-quality gypsum reserves, part ore deposit is put overexploitation and is approached exhaustion, and part causes high-quality resource to waste because mixing to be difficult to separate with low-grade gypsum; Therefore, Chinese practice can exploit and effectively utilize high-quality gypsum resource ratio still less.In order to ensure the Sustainable development of overall gypsum industry, green, environmental protection, healthy gypsum building material and the product that produce are applied in people's lives widely, must be optimized utilization to limited gypsum resource.
There is a large amount of gypsum mines in gypsum mining area, can well be developed.
Mud is the smelly paste of a kind of easy corruption producing in sewage treatment process, its enrichment the pollutent in sewage, contain the hazardous and noxious substances such as the nutritive substances such as a large amount of nitrogen, phosphorus and organism, viral micro-organisms, parasitic ovum, heavy metal, without effectively processing and dispose, will environment be produced to serious harm.
Sludge moisture content >=80% that municipal sewage plant produces, mud is alkalescence mostly, and pH value is 8～10, the product of unsuitable direct production recycling.
Investigation shows, at present China has 80% mud not to be effectively addressed, and even has greatly and is simply discarded in the PE such as farmland, river, becomes new source of pollution.
At present a large amount of not mud of stabilizing treatment has become the heavy burden of sewage work, how mud huge output, complicated component is properly processed safely, makes that it is innoxious, minimizing, resource utilization, has become dark concerned key subjects.
Nutrition Soil is the multiple mineral nutrition that contains of preparing specially in order to meet seedling growth growth, loose ventilation, and preserve moisture and fertility ability is strong, without the soil of disease and pest.Generally formed with decomposed dung mixed preparing by fertile land for growing field crops soil, also be selected from import high-quality peat, coconut palm chaff, the Nutrition Soil mixing in specific proportions, but these Nutrition Soils are not through reasonably preparing burden and strict sterilization, are unfavorable for that the normal growth of nursery stock is grown.
Because Nutrition Soil is after treatment low weight and loose, the conventional products volume of Nutrition Soil is relatively large, is unfavorable for reducing the cost of producing and transporting.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of production method of gypsum mine compression Nutrition Soil is provided.
The production method of gypsum mine compression Nutrition Soil: first mud is carried out to acidification, then the batching that gypsum mine compresses Nutrition Soil is stirred, is packaged as finished product after compression, microwave temperature sterilization.
The materials such as mud, quick dissolved sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high sticky attapulgite clay, natural pond liquid, the natural pond slag of gypsum mine compression Nutrition Soil after by gypsum mine, acidifying after dewatering, vegetable fibre, expanded vermiculite, pearlstone and High hydrophilous resin after pulverizing form.
Adopt high-temperature flue gas that gypsum mine is dehydrated into semi-hydrated gypsum, to strengthen the pectisation of gypsum mine, gypsum mine, after processed, can improve the utilization ratio of gypsum mine, turns waste into wealth.The present invention selects the gypsum mine after pulverizing, particle fineness≤0.5 millimeter of gypsum mine.
Attapulgite has unique dispersion, high temperature resistant, the anti-good colloidal property such as saline and alkaline and higher adsorptive power, and has certain plasticity-and cohesive force.Concavo-convex excellent stone clay after the acidify can adsorb foreign odor taste, heavy metal ion and the carcinogenic substance in mud, keep the nutritive ingredient in mud not run off, be conducive to growing of plant, the present invention selects the attapulgite clay after pulverizing, particle fineness≤5 millimeter of attapulgite clay, water content≤15% of attapulgite clay.
