Description
Technical field
The invention belongs to marine ecology technical field, and in particular to a kind of utilization feces of livestock and poultry prepares the side of ecological reef
Method.
Background technology
With the reinforcing and the development of marine economy of marine territory idea, each state all pays much attention to the protection to maritime rights and interests
Utilized with the scientific development of marine resources.But, since last century, as environmental pollution and the transition of the mankind such as fish at the reason sea
Foreign ecological environment receives heavy damage, and offshore sea waters Desertification is protruded.In order to recover marine ecology and vow ocean state
Native sovereignty, each state has all carried out a series of " ecological islands and reefs " recovery project, carries out impaired island body, vegetation, water front, sandy beach and week
Side marine site etc. is repaired, and has carried out islands and reefs construction project, carries out aquafarm construction.Meanwhile, implement territorial waters basic point island protection work
Journey, carries out islands and reefs ecological preservation area construction etc..Either ocean islands and reefs are built, or aquafarm construction, deliver artificial reef,
Abundant nutrition material is the important step for building marine organisms rapid multiplying habitat.Artificial reef be divided into collection fish shelter, induction reef,
Reef, propagation reef, marine alga reef etc. are bred as, at present, constructing the material of reef includes steel, plastics, stone, concrete, rubber etc.（Tang
It is bright, Zhao Jinbo, the research of high-performance sea-farming abalone Special artificial reef,《Concrete》, 2003,160（2）：3-6；Zhang Jing
Pine etc., patent of invention, artificial reef, ZL 201310543435.6）, in these materials：Rubber, steel etc. can be to marine organisms
It can cause to poison, suppress its fast-growth, and some other material, such as stone, concrete and plastics, although to marine organisms
It is nontoxic, but attached algae less effective.In order to accelerate the recovery of marine ecology, promote ocean beneficial organism fast-growth, Yu Zonghe
Deng by the way that the material for preparing artificial reef is mixed with slow release fertilizer, shaping is then poured, or artificial reef is poured into shaping
Afterwards, the coating rich in slow release fertilizer is coated on its surface, a kind of good reef of surface algae adhesion effect is made（Yu Zonghe etc.,
Patent of invention, a kind of method of raising attaching effect of algas on surface of artificial reef, ZL201110118155.1）, achieve certain
Achievement, but the nutrition salt component of this method addition is single, promote for abundant ocean biological species it is not enough, meanwhile, cost
Also it is higher, limit it and widely apply.On the other hand, due to factors such as environmental pollutions, heavy metal, radiation in some seawater
The harmful substances such as property element can be exceeded, and these materials can also influence the recovery of marine ecology and the quality of marine product, but existing
Artificial islands and reefs material do not possess the abilities of the harmful substances such as removing heavy metals.Exploitation one kind can discharge nutriment, again
Ecological artificial reef that be capable of Adsorption harmful substance, low cost is very important.
As China's livestock and poultry breeding industry is developed rapidly, the feces of livestock and poultry of plant's discharge causes very big pressure to environment
Power.In traditional agriculture, feces of livestock and poultry is all to be used for agricultural production after compost, still, in modern livestock and poultry cultivation industry, is
The yield and quality of meat, eggs and milk, and needs of preventing and curing diseases are improved, can add in feed substantial amounts of rich in micro-
Nutritional ingredient and various additives, after livestock and poultry feed, these materials have can greatly be arranged with fecaluria in the form of original shape
Release and, so, in feces of livestock and poultry in addition to containing protein, amino acid and cellulose wood quality, it can also contain substantial amounts of copper
The heavy metals such as iron zinc, and the harmful substance such as antibiotic and growth promoter.Traditional composting process, it is impossible to which effectively removing these has
Evil material, these harmful substances enter soil with muck, can agricultural product and environment be caused with serious harm.It is therefore desirable to visit
Feces of livestock and poultry is begged for utilize and processing new way.
In order to prepare multifunctional ecological artificial reef, feces of livestock and poultry is comprehensively utilized, the present invention prepares one using feces of livestock and poultry
Plant the artificial reef with absorption and nutrition slow-release function.
The content of the invention
The purpose of the present invention, is to provide a kind of utilization feces of livestock and poultry and prepares with Adsorption of Heavy Metals and discharge nutriment
The method of ecological reef.It is related to the construction of marine ecology islands and reefs, the construction of seabed pasture and marine ecology to recover to build manually reef
The comprehensive utilization of stone material and feces of livestock and poultry.
The technical scheme of use is
A kind of method that utilization feces of livestock and poultry prepares ecological reef, it is characterised in that this method comprises the following steps：

Acid solution and phosphoric acid solution volume ratio are 2Kg:1L:1L ratios, are separately added into salpeter solution and concentration that concentration is 1-3moL/L
For 0.3-1mol/L phosphoric acid solution, stir, be heated to 60-80 DEG C of holding 10-30min, separation of solid and liquid obtains solid A
And liquid A；
2）The phosphoric acid that the mass percentage concentration of the quality such as addition is 85% in the solid A obtained to step one, stirs, in 350
Under the conditions of DEG C -500 DEG C, vacuum calcining 30-70min is washed to weakly acidic pH, drying, pulverizes and sieves, and obtains particle diameter for 0.1-
2.4mm solid B；
3）The ratio between molal quantity according to calcium and magnesium is 1:1, and the ratio between total mole number and the stool quality kilogram number of calcium and magnesium are 0.25-
1:Add the compound of calcic and magnesium in 1 ratio, the liquid A obtained to step one, stirring reaction completely, then adjusts with ammoniacal liquor its pH
It is worth for 6-8, adds the 5%-20% of stool quality diatomite, stirs, stand 12h, separation of solid and liquid obtains solid C and liquid
Body C；
4）The solid C drying that step 3 is obtained, adds the 20%-50% of solid C mass adhesive, ball milling 0.5-6h, profit
It is wet, the spherical material that particle diameter is 2.5mm-15mm is made, after drying, calcines 20min-40min in 950-1300 DEG C, obtains porous ball
D；
5）The porous ball D that the solid B and step 4 that step 2 is obtained are obtained is immersed in the liquid C that step 3 is obtained respectively,
12-24h is soaked, abundant saturation is taken out, 105 DEG C of drying are 1 according to porous ball D, solid B and cement for construction in sea mass ratio:
0.03-0.2:0.2-0.3, feeding is well mixed, then by water and cement quality ratio is 0.2-0.24:1 ratio adds water, and stirring is equal
It is even, mould molding is injected, the shape of needs is made, hardening curing 28 days obtains having release nutriment and Adsorption of Heavy Metals
The concrete material of function, available for recover marine ecology rich water islands and reefs shore protection stone, also can as seabed pasture artificial reef
Stone.
Described feces of livestock and poultry is the herbvore excrement with omnivorousness cultivated animals.
In the compound that calcic and magnesium are added in described step three, the compound of calcium is calcium oxide, calcium hydroxide, carbonic acid
One or more in calcium, calcite, lime stone, the compound of magnesium is one or both of magnesia, magnesium carbonate.
The adhesive added in described step four is one kind in clay or kaolin.
Cement for construction in sea strength grade used is 42.5 low alkalinity cement in described step five.
It is an advantage of the current invention that while innoxious, comprehensive utilization of resources feces of livestock and poultry, preparing cheap having and inhaling
The attached artificial reef for removing harmful heavy metal function and release nutriment, twice laid, energy-conserving and environment-protective, with very high environment
Benefit and economic benefit.
