Description
Technical field
The present invention relates to soil field, be specifically related to a kind of method of utilizing lake silt to produce ecological, environmental protective water-preserving nutritive alms bowl.
Background technology
In order to improve the water quality in lake, river, guarantee the unimpeded of the normal flood carrying capacity in river course and navigation channel, harbour, China has carried out large-scale dredging and desilting engineering, according to statistics, bottom mud in Taihu Lake ecological dredging amount approximately 6700 ten thousand steres only, Delta of the Pearl River area dredging silt amount approximately 8000 ten thousand steres, Future Ten year water conservancy, He Hu, port dredging and desilting engineering in still will produce a large amount of dredging silts, become and be difficult to the reality of avoiding.
The dredging silt producing in dredging engineering adopts the method for stacking or abandoning to process conventionally, cause on the one hand the waste of a large amount of land resourcess, to ecotope, will cause very large destruction, on the other hand, dredging silt contains heavy metal, organic pollutant, various pathogenic bacteria and Parasites mostly, will inevitably cause secondary pollution to surrounding enviroment.
Due to edible fungi residue all can be in various degree the living contaminantses such as generation such as green mold, mould, aspergillus, head mold, Mucor and bacterium, can not be directly used in fertilising, in a large number mouldy, blackout, acid bacterium slag smelly and that be bacterial contamination be arbitrarily deposited in field, highway both sides or two sides, river, cause the environment of traffic jam and polluted air, soil and river.
The pollutent that livestock and poultry farms in scale produces mainly contains solid manure, sewage and foul gas; in fecaluria movement and waste water, contain a large amount of nitrogen, phosphorus, suspended substance and pathogenic bacterium; amount of pollutants is large and concentrated, especially serious with water pollution and stench pollution on the environment.
Feces of livestock and poultry is the important substance basis of biogas fermentation; most of livestock and poultry farms in scale all has biogas electricity generation apparatus; after marsh gas power generation, can produce Ye He natural pond, natural pond slag; although Ye He natural pond, natural pond slag can be for the production of fertilizer; but a large amount of Ye He natural pond, natural pond slags still can well be utilized; some livestock and poultry farms utilize unprocessed random discharge on rainy day, serious pollution local ecotope.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of method of utilizing lake silt to produce ecological, environmental protective water-preserving nutritive alms bowl is provided.
Utilize lake silt to produce the method for ecological, environmental protective water-preserving nutritive alms bowl: first ecological, environmental protective water-preserving nutritive soil to be added in the two shaft pugmill mixer having moved, again natural pond liquid water-holding agent is evenly added in ecological, environmental protective water-preserving nutritive soil, after ecological, environmental protective water-preserving nutritive soil and natural pond liquid are uniformly mixed, be transported in full-automatic forming machine for soil block, be pressed into difform ecological, environmental protective water-preserving nutritive alms bowl work in-process, maintenance is carried out in conventional maintenance process according to cement products, within 28 days, is the finished product of ecological, environmental protective water-preserving nutritive alms bowl afterwards.
Edible fungi residue, ferrous sulfate, zinc sulfate, ammonium molybdate, copper sulfate, borax, manganous sulfate, natural pond liquid, natural pond slag, High hydrophilous resin and cement composition after the feces of livestock and poultry of ecological, environmental protective water-preserving nutritive alms bowl after by lake silt, high sticky attapulgite clay powder, bentonite in powder, fermentation, edible fungi residue, carbonization.
Lake silt is to have adopted the mud of stacking or abandoning in the engineerings such as dredging harbour, navigation channel, lake and river, in lake silt, contain the elements such as a large amount of nitrogen, phosphorus, potassium, its content surpasses general soil, and these elements necessary nutrition of plant-growth just, the present invention selects the lake silt after pulverizing, the water ratio of lake silt is less than 25%, and particle fineness is less than 5 millimeters.
Attapulgite clay be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, high sticky attapulgite clay soil property is fine and smooth, water-absorbent is strong, higher viscosity and the plasticity-of tool when wet, be conducive to the bonding between ecological, environmental protective water-preserving nutritive alms bowl raw material, and can adsorb heavy metal ion and the carcinogenic substance in ecological, environmental protective water-preserving nutritive alms bowl, also can deodorizing eliminate the unusual smell, keep the nutritive ingredient in ecological, environmental protective water-preserving nutritive alms bowl not run off, be conducive to growing of plant.
High sticky attapulgite clay powder refers to gets 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, suspension cup is placed on homogenizer, under the rotating speed of 11000 revs/min, stir 20 minutes, to pour in the beaker of 250ml through high-speed stirring sample suspension again the viscosity of using NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value>=2200 into
mPasattapulgite clay powder be high sticky attapulgite clay powder, the sticky attapulgite clay powder particles of high fineness≤0.074 millimeter that the present invention selects.
Bentonite in powder has strong water absorbability and swelling property, adsorbable 8～15 times to the water yield of own vol, volumetric expansion can reach even 30 times of several times; In water medium, can be dispersed into as a form of gel and suspension, this medium solution has certain glutinousness, thixotropy and oilness; There is stronger cation exchange capacity (CEC); Various gas, liquid, organic substance are had to certain adsorptive power, and maximal absorptive capacity can reach 5 times to the weight of self; The admixture of it and water, mud or fine sand has plasticity-and agglutinating value(of coal), bentonite in powder particle fineness≤0.074 millimeter that the present invention selects.
