Description
Technical field
The present invention relates to light-duty long-acting cultivation matrix for roof greening of a kind of sludge organism charcoal base and preparation method thereof.
Background technology
Urban architecture increasingly emphasizes building with the coordination of natural environment, it is necessary to which more vert spaces are incorporated into building
In.Roof greening is using the top platform of building as the space Virescence form for building garden landscape is relied on, in reduction airborne dust, only
Remarkable effect is generated in terms of changing air, alleviation urban heat land effect, while also add city's green areas, city is saved and uses
Ground, enriches City Green landscape.Therefore, roof greening has become the building trend of Cities with Great Population.Roof greening is made
To be different from the garden style of ground greening, there is particular/special requirement in cultivation matrix selection.In view of mitigating roof load, roof
Greening cultivation matrix needs lightweight；From the aspect of roof drainage, matrix granule can not be too small, it is impossible to blocks drainage pipeline.Often
The requirement in terms of cultivation matrix does not possess above-mentioned two typically is afforested on rule ground, therefore, for grinding for cultivation matrix for roof greening
Hair turns into technical barrier urgently to be resolved hurrily.
Municipal sludge is the sediment in the processing procedure of city domestic sewage, and its processing handling problems are always
Perplex the problem of urban development.At present, municipal sludge is prepared into charcoal by the charing of low temperature pyrolysis technology, turned into
One of important way that reclaiming city domestic sludge is utilized.The sludge organism charcoal of lightweight, which has, turns into cultivation matrix for roof greening
Potential quality, however, the research of sludge organism charcoal base cultivation matrix for roof greening is but rarely reported.
There is researcher to do the exploration of correlation as cultivation matrix for roof greening by material of municipal sludge.Application number
For 201410464951.4 and 201010272600.5 patent using municipal sludge as primary raw material, pass through aerobic compost
Technique prepares cultivation matrix for roof greening material.Though the product after sludge composting fermentation is used as roof with higher fertility
Afforesting matrix, unit weight is still higher, and particle is met yew and dissipated, and easily causes blockage of sewer.In addition, aerobic composting process control
If system is bad, the killing of sludge composting product pathogen is not thorough, can infect plant, sludge composting product can also give an offensive smell,
Easily recruit and lure worm bird.
Municipal sludge charcoal is by the product after sludge carbonization, different from common carbon black by low temperature pyrolysis technology
And activated carbon, it is a kind of new environmentally conscious materialses.The material have unit weight it is small, sterilization thoroughly, free from extraneous odour, loose porous feature,
Further, since with high specific surface area, sludge organism charcoal can as fertilizer slow-released carrier, and itself organic carbon content compared with
Height, meanwhile,, can completely with " water, fertilizer, air and heat " feature required for cultivation matrix with good retain water and nutrients effect
Performance is not the effect that soil but surpasses soil.Using sludge organism charcoal as the cultivation matrix of roof greening, city life is opened
The new way that recycling sludge living is utilized, with important society and ecological significance.
The content of the invention
It is an object of the invention to provide a kind of light-duty long-acting cultivation matrix for roof greening of sludge organism charcoal base and its preparation
Method, the cultivation matrix for roof greening is mainly using sludge organism charcoal as main material, auxiliary addition long-acting sustained-release complex fertilizer,
What water-loss reducer and perlite were prepared.
To achieve the above object, technical scheme is as follows：
A kind of light-duty long-acting cultivation matrix for roof greening of sludge organism charcoal base, the sludge organism charcoal refer to limit oxygen or
Under oxygen free condition, by low temperature pyrolysis technology, the excess sludge of city domestic sewage treatment plant is carbonized to the charcoal prepared.
The light-duty long-acting cultivation matrix for roof greening method of clicking of described sludge organism charcoal base is prepared：
（1）The preparation of municipal sludge charcoal：By the natural desiccation of the sludge of city domestic sewage treatment plant, now sludge
Moisture content is between 80-84%.Then dewatered sludge is placed in large-scale Muffle furnace, be heated to 10 DEG C/min heating rate
300 DEG C, temperature 4h is maintained, is pulverized and sieved after after charcoal cooling, prepares the sludge organism charcoal that average diameter is about 3mm
Product.
（2）The formula of cultivation matrix：By step（1）Gained sludge organism charcoal is mixed with long-acting sustained-release complex fertilizer, water-loss reducer, perlite
Even, mass percent difference is as follows：Sludge organism charcoal 82%, long-acting sustained-release complex fertilizer 1-2%, water-loss reducer 2-4%, perlite 12-
15%.The single nutrient content that durable composite fertilizer in formula refers to composition product is not less than 4.0%, nitrogen, phosphorus, potassium available nutrient content
>=45% commercially available composite fertilizer.Water-loss reducer in formula refers to acrylamide and acrylic acid salt crosslinking copolymerization thing（Polyacrylamide,
Sodium Polyacrylate, polyacrylic acid potassium, ammonium polyacrylate）.Perlite refers to commercially available garderning green expanded perlite.
The physicochemical property of cultivation matrix for roof greening of the present invention is：Dry density is 0.42-0.51g/cm3, it is wet to hold
Weight is 0.79-0.87 g/cm3, total porosity is 62%-71%, pH value 6.0-7.5.
It is an advantage of the invention that：
（1）Unit weight is light.Dry density is 0.42-0.51g/cm3, wet density is 0.79-0.87 g/cm3, it is that common ground gardens are green
Change 1/3-1/2 of matrix or so, can significantly mitigate roof load.
（2）Fertilizer efficiency is long.Sludge organism charcoal sheet coordinates with slow-release compound fertilizer, can met for a long time as the slow-released carrier of fertilizer
The nutritional need of Green Roof Plants.
（3）It is not easily blocked drainage pipeline.The various materials of matrix are graininess, material of main part sludge organism charcoal average diameter of particles
3mm, and with certain mechanical strength, meet water and do not dissipate, be not easily blocked roof drainage system.
（4）Retain water and nutrients.Matrix general porosity is 62%-71%, with preferable ventilation effect, is conducive to plant root growth,
Plus the use of water-loss reducer, while can retain water and nutrients.
（5）Matrix health.Sludge organism charcoal free from extraneous odour, does not recruit and lures worm bird.Sludge organism charcoal is after high temperature carbonization, and pathogen is killed
Thoroughly, Green Roof Plants will not be infected.
（6）It is applied widely.By adjusting the ratio of the dispensing in addition to sludge charcoal, matrix is applied to most of roof greenings
Plant.Further, since unit weight is lighter, it is adaptable to various roof greening purposes.
（7）Cost is reasonable.Sludge used in matrix is obsolete material, convenient material drawing.Remaining material cost is all relatively low, matrix entirety valency
Lattice are rationally, easy to utilize.
