Description
Technical field
The present invention relates to Carbon Materials to prepare, particularly to the Rain Garden utilizing new bio Carbon Materials.
Background technology
Rain Garden is the scrobicula greenery patches of self-assembling formation or hand digging, it is used to converge and absorb the rainwater from roof or ground, rainwater is made to be purified by the comprehensive function of plant, sandy soil, and so as to penetrate into soil gradually, recharging groundwater, or so as to feed the urban water such as landscape water, lavatory water. It is rainwater management and the rainwater utilization facility of a kind of ecological sustainability. In actual configuration, Rain Garden frequently includes gravel layer, layer of sand, planting soil layer, cover layer and aquifer. The water yield is substantially contained in effect and water quality two parts control: last point of the water yield is stagnant storage, namely ensures certain hydraulic detention time, reduces municipal drainage pressure, is one " slow releasing agent ". The control of water quality is most difficult to realize, owing to rain water pollutant is numerous, complicated component, the mechanism that traditional minimizing technology mechanism and soil remove pollutant is suitable, but soil is limited for the removal ability of pollutant, absorbability especially for some heavy metals or organic pollution is relatively low, thus the water body containing pollutant can be caused to enter into subsoil water through soil filtering layer, layer of sand, causes underground water pollution. In addition, owing to needing plantation landscape plant on Rain Garden, the effect of plant can absorb the pollutant in water body on the one hand, may also function as beautification of landscape effect on the other hand, but in plant maintenance, need spraying pesticide, chemical fertilizer, the pollution to subsoil water subsoil water can be entered into, thus can be aggravated with the runoff of rainfall.
Therefore, traditional at present Rain Garden also exists following deficiency: the removal ability of the heavy metal contained in rainwater, organic pollution is limited; Plant in Rain Garden can effectively absorb polluter; Further, pesticide, the applying and new polluter can be brought of chemical fertilizer; Further, Rain Garden is when fine day, owing to the water holding capacity of soil is poor, so that the carrying out of variable interval is poured into a mould, cause the waste of water resource.
Summary of the invention
In order to solve the deficiency in above-mentioned prior art, the preparation method that the invention provides the new bio Carbon Materials that a kind of detergent power is strong, nutritious, turn waste into wealth.
It is an object of the invention to be achieved through the following technical solutions:
A kind of Novel rainwater garden, described Rain Garden includes top-down cover layer and gravel layer; Described Novel rainwater garden farther includes:
Mixed layer, described mixed layer is between described cover layer and gravel layer, and described mixed layer includes biological carbon materials and soil, described biological carbon materials is graininess, wherein carbon content is at 55%-65%, and the content of organic matter is at 35-40%, and nutrient is at 5%-10%.
According to above-mentioned Novel rainwater garden, alternatively, described Novel rainwater garden farther includes:
Soil horizon, described soil horizon is between described mixed layer and gravel layer.
According to above-mentioned Novel rainwater garden, alternatively, described Novel rainwater garden farther includes:
Biological layer of charcoal or layer of sand, described biological layer of charcoal or layer of sand are between described soil horizon and gravel layer, and described biological layer of charcoal includes biological carbon materials.
According to above-mentioned Novel rainwater garden, it is preferable that the preparation method of described biological carbon materials is:
(A1) straw, municipal sludge and feces are sent in agitator and stir;
(A2) the mixture mummification after stirring;
(A3) mixture after mummification send carbonization in retort.
According to above-mentioned Novel rainwater garden, it is preferable that the mass ratio sending into the straw in described agitator, mud and feces is 1-3:1-2:1.
According to above-mentioned Novel rainwater garden, it is preferable that in step (A2), the environment of mummification is:
Mummification temperature is 120-150 degree, and the time of staying is 3-5 hour.
According to above-mentioned Novel rainwater garden, it is preferable that in step (A3), the temperature of carbonization is step increments.
According to above-mentioned Novel rainwater garden, it is preferable that the concrete mode of described step increments is:
With �� T1/ min is warmed up to T1, and time of staying t1; Again with �� T2/ min is warmed up to T2, then time of staying t2, �� T1> �� T2��
According to above-mentioned Novel rainwater garden, it is preferable that described T1It is 200 degree, described T2It it is 550 degree.
According to above-mentioned Novel rainwater garden, it is preferable that described t1It is 0.5 hour, described t2It it is 2 hours.
According to above-mentioned Novel rainwater garden, it is preferable that described �� T1It is 10 degree, described �� T2It it is 5 degree.
Compared with prior art, the device have the advantages that into:
1. in this biological carbon materials, carbon content can maintain about 60%, owing to carbon structure has bigger specific surface area, the absorbability of heavy metal or organic pollution is very strong, it it is 400 times of normal soil absorbability, pollutant in energy effectively catching rainwater, and it not being easily formed desorption phenomenon, it is to avoid the pollutant in rainwater penetrate soil horizon and enter into subsoil water, and subsoil water is polluted;
2. containing domestic sludge in charcoal raw material, containing substantial amounts of nutrient in municipal sludge, carbonisation is preserved, thus N in the charcoal composition after entirety carbonization, the nutritive element contents such as P are higher, and nutrient is enriched on carbon structure, whole growing process can be continuously available to plant nutrient by slow releasing, substantially increase the utilization rate of nutrient, in addition, by the nutrient that the organic-inorganic pollutant that charcoal absorption is fixing are also plants, accomplish to turn waste into wealth, charcoal is made to form an open circulation in adsorption process, substantially prolongs the time that charcoal absorption is saturated,
Simultaneously, owing to the charcoal after preparation contains a certain amount of wood vinegar, it is possible to significantly suppress the harmful microorganism harm to plant in soil, thus greatly reducing applying of pesticide and chemical fertilizer on the whole, also indirectly avoid fertilizer and pesticide and enter into surrounding lakes with current, cause the pollution to water body;
3. turn waste into wealth, the recycling of garbage: the raw material of this charcoal respectively straw, municipal sludge and animal wastes composition, these three material is all garbage to a certain extent, particularly municipal sludge, country is often based on traditional landfill on sludge treatment and burns at present, not only cause the secondary pollution to environment, and result also in a large amount of wastes of " resource ", therefore this invention well solves the problem of outlet of bio-waste to a certain extent, by dry distilling carbonization, it is possible not only to play the effect of abatement, and residue is good resource, in improvement Soil structure, in absorption fixed environment, the aspect such as pollutant has extraordinary effect, can really realize the industry chain of circular economy from waste resources.
