Description
Technical field
The present invention relates to Nutrition Soil, be specifically related to a kind of production method of pyrophillite mine tailing compression Nutrition Soil.
Background technology
Pyrophillite is the one of clay mineral, and ore, taking bulk as main, also has earthy and fibrous, pyrophyllite normal with the mineral intergrowth such as quartz, kaolinite, montmorillonite, dickite, sericite and kyanite, andalusite, corundum.
There is a large amount of pyrophillite mine tailings in pyrophillite mining area, can well be developed.
Mud is the smelly paste of a kind of easy corruption producing in sewage disposal process, its enrichment the pollutant in sewage, contain the poisonous and harmful substances such as the nutriments such as a large amount of nitrogen, phosphorus and organic matter, 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, should not directly produce the product of 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 pollution sources.
At present a large amount of stable mud of processing has become the heavy burden of sewage treatment plant, how mud huge output, complicated component is properly processed safely, makes that it is innoxious, minimizing, resource, 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
