Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of biological bacterium source soil conditioner based on eutrophy bottom material
And its preparation process.
Background technique
Vegetable oil esters chemical plant produces fatty acid ester, the esterification bottom material generated in production process by raw material of vegetable oil
Rich in fatty type organic, its content of organic matter reaches 8% or more, and the processing method in industry is will to be esterified bottom material to send to special
The waste water treatment plant of industry is handled, but since the content of organic matter of esterification bottom material is high, COD high, the processing cost through processing plant is very
Height, this often becomes the restraining factors of influence company yield.
Plant oilmill commonly uses carclazyte as decolorising agent during vegetable oil refining, removes the pigment object in grease
Matter, carclazyte can adsorb a large amount of greases during this, and the content of grease 20% or more, generally locate by vegetable oil mill in bleaching clay
The raw material to qualified factory as carclazyte oil is managed, but the processing for producing the spent bleaching clay after carclazyte oil is still very severe asks
Topic：The secondary pollution that will cause soil is buried, calcining and activating energy consumption is too high.
Bacillus is a kind of easy bacterium, is the dominant population in soil, wherein bacillusmusilaginosiengineering can decompose
Solid-state aluminosilicate in soil is soluble silicon, and it is titanium pigment that millet straw bacillus, which has the insoluble phosphorus decomposed in soil,
Effect, bacillus megaterium can be very good degradation soil in it is organic phosphorus, be commonly used to production phosphorus decomposing consolidate potash fertilizer.
It is the carbon source for cultivating bacillus using the organic matter in esterification bottom material and bleaching clay, can both efficiently uses bottom material
In nutriment, rapid amplifying bacteria concentration, reduce esterification bottom material and bleaching clay organic pollution.Can decompose again can
Dissolubility silicon, uses as biological silicon fertilizer and soil conditioner, and being truly realized turns waste into wealth.
The processing method of microbial manure and soil conditioner generally uses finished product microbial inoculum and inorganic mineral carrier mixed at present
It closes, thallus only has adhewsive action on carrier, is unfavorable for the rapid amplifying of microbial inoculum in the soil, affects the use of bacteria agent
Effect, 106497574 A application of patent CN disclose a kind of preparation method of complex microorganism multielement soil conditioner, with
It is carrier that deimpurity silico-calcium magnesium powder is gone after high-temperature calcination, is aided with organic matter, amino acid, adsorbs silicate bacteria, withered grass
The mix bacterium agent production soil conditioner of bacillus, EM bacterium.Patent CN 106747176 A Shen Qing Publication is a kind of have it is solid
The novel gelled material of carbon ability and its preparation and application method, silicate is loaded using porous calcium carbonate or graphite
Bacterium is prepared into silicate bacteria bacterium powder, is mixed with to obtain cementitious material with calcium hydroxide.102174498 Shen B patent CN
Please disclose a kind of purposes of the silicate bacteria carrier and preparation method thereof with it, silicate bacteria carrier be by turf with it is siliceous
Substance or turf, silicon-containing material and bentonite composition.A kind of microorganism phosphate fertilizer of patent CN 106146111 A Shen Qing Publication and
It is applied, and three kinds of bacterial strains any in bacillus subtilis, nitrogen-fixing bacteria, rhizobium and silicate bacteria are adsorbed in carrier straw respectively
On stalk, humic acid or farmyard manure, then add 30%-40% monoammonium phosphate and 10% calcium superphosphate is produced.
Summary of the invention
The biological bacterium source soil conditioner and its preparation that the purpose of the present invention is to provide a kind of based on eutrophy bottom material
Technique, to solve the problems of the prior art.
To achieve the above object, the present invention provides the following technical solutions：A kind of biological bacterium source based on eutrophy bottom material
The preparation process of soil conditioner, includes the following steps：
