Production method for lake sludge carbonized nutrient soil

Abstract

The invention discloses a production method for lake sludge carbonized nutrient soil. According to the technical scheme, the key point is that ingredients of the lake sludge carbonized soil are stirred and extruded into sheet-shaped particles; the sheet-shaped particles are processed into lake sludge carbonized soil; and the ingredients of the lake sludge carbonized nutrient soil are pelletized and sterilized, and packaged into the lake sludge carbonized nutrient soil. The lake sludge carbonized nutrient soil consists of lake sludge, active clay waste residues, peat, attapulgite clay, bentonite, zeolite, waste, vermiculite, diammonium phosphate, perlite, ferrous sulfate and super absorbent resin. The lake sludge carbonized nutrient soil contains plenty of nitrogen, phosphor, potassium, organic substances and trace elements, is high-quality nutrient soil which is complete in nutrition ingredients, high in fertilizer efficiency, sterile, harmless, free of odor and good in water retention capacity, and is suitable for planting flowers and plants, and nursery-grown plants; and the production method for the lake sludge carbonized nutrient soil is suitable for producing carbonized nutrient soil and a nutrition medium.

Description

Technical field [0001] The invention relates to nutrient soil, in particular to a production method of lake silt carbonized nutrient soil. Background technique [0002] Most of the nutrient soil raw materials used in flower seedlings are mixed and prepared from landslide, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste, humus and other materials. These nutrients The soil has not undergone reasonable ingredients and disinfection. It has poor water and fertilizer retention capacity, poor air permeability, and is easy to compact. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings will also be affected by viruses and bacteria in the soil. And the infringement of newly germinated weeds is not conducive to the normal growth and development of flowers and seedlings. [0003] Both phosphorus and potassium are essential nutrients for the growth of flower and seedlings. A...

Problems solved by technology

[0005] The dredged silt produced in the dredging project is usually disposed of by stacking or discarding. On the one hand, it not only causes a lot of waste of land resources, but also causes irreparable damage to the ecological environment. On the other hand, most of the dredged silt contains heavy metals and organic pollutants. , will inevitably cause secondary pollution to the surrounding environment

[0006] Due to the high water content of dredging silt produced by ports, waterways, lakes and rivers, it is not easy to dehydrate, and the clay particles are many, low in strength and large in size, which brings many disadvantages to the transportation, storage and use of silt, and no proper solution can be found. Therefore, we have to send the dredged silt together with mud and water to the garbage station to wait for its natural weathering. This treatment method not only pollutes the environment, but also brings a huge and unnecessary cost to the government. overhead
