Abstract
The method that sludge prepares vegetation soil is remained after a kind of metallic iron acidification, handled by the sludge for the heterogeneity for remaining different step in metallic iron processing procedure, preparing can be with planting soil used in vegetation, environment will not only be polluted, and the growth of the element also to plant such as the phosphorus being rich in has facilitation, has been truly realized waste harmless treatment and the effect utilized.
Description
Technical field
The present invention relates to environmental technology field, and in particular to sludge is remained after a kind of metallic iron acidification and prepares vegetation use
The method of soil.
Background technology
Oneself turns into serious environmental pollution hidden danger for sludge produced by the city increasingly increased sharply, Industrial Waste Water Treatments factory, and
As new environmental pollution improvement's difficult point.General sewage plant sludge processing method mainly has dehydration, modification, desiccation etc., disposal
Method mainly fills out sea, landfill, land use, building materials, burning etc., and the processing of above-mentioned sewage plant sludge is above-mentioned sludge
The precondition of disposal.The sludge of generation particularly after plating acidification is more difficult to handle, once arbitrarily discharge, will make
Into very big pollution, and existing landfill method floor space is big, must make Anti-seeping technology, also to build methane recovery system and diafiltration
Water treatment plant, is easily polluted to underground water and surrounding air, and resource can not be recycled, and because sludge has stream
Dynamic property, individually landfill difficulty is very big, for populous, for China of cultivated land resource growing tension, is increasingly difficult to apply
OK；Land use is hardly formed scale by scope and seasonal limitation is used, and easily causes the secondary pollution of environment,
The acceptance level of the common people is also low, and the particularly sludge containing heavy metal can not carry out land use, and these sludge can not be direct
For planting vegetation.
The content of the invention
In order to solve the deficiencies in the prior art, prepared by the residual sludge after a kind of metallic iron acidification that provides of the invention
The method of vegetation soil.
The technical solution that the present invention is used is：Sludge is remained after a kind of metallic iron acidification and prepares vegetation soil
Method, described residual sludge includes acidification and remains sediment after sludge and metal phosphorizing processing, comprises the following steps：
（1）Acidification residual sludge is obtained from the stone cistern of hydrochloric acid and sulfuric acid acidified metal iron, acidification is remained
Sludge is pressed into clod with filter press, and clod pack is placed into the progress of more than three months time from fermentation, then by from after fermenting
It is exposed to the sun under the clod sun or with electrothermal furnace in being dried at 650-700 DEG C, the part clod after drying is beaten and is fine into mud powder, by 15-
20% mud powder is mixed with 80-85% clods as vegetation base soil；
（2）Take sediment after metal phosphorizing processing from phosphoric acid, the steel tank of zinc oxide processing, sediment is placed three
More than individual month time was carried out from fermentation, then will be exposed to the sun under the sediment sun after fermenting, and was used as vegetation chemical fertilizer；
（3）By step（1）The vegetation base soil and step of preparation（2）The vegetation of preparation mixes to obtain final product vegetation with chemical fertilizer
With soil, wherein vegetation is 0-10% with fertilizer amount.
Described step（1）The moisture content that middle filter press is pressed into clod is 15%.
Described step（1）Clod is as primer in vegetation base soil, and mud powder, which is located on clod, is used as absorbent material.
The beneficial effects of the invention are as follows：The invention provides remain sludge after a kind of metallic iron acidification to prepare vegetation use
The method of soil, is handled by the sludge for the heterogeneity for remaining different step in metallic iron processing procedure, is prepared available
Soil used, will not only be polluted to environment on vegetation is planted, and the growth of element also to plant such as the phosphorus being rich in
There is facilitation, be truly realized waste harmless treatment and the effect utilized.
Embodiment
The residual sludge generated in metallic iron processing procedure includes sinking after acidification remains sludge and metal phosphorizing processing
Starch.
The method that sludge prepares vegetation soil is remained after a kind of metallic iron acidification, is comprised the following steps：
（1）Acidification residual sludge is obtained from the stone cistern of hydrochloric acid and sulfuric acid acidified metal iron, acidification is remained
Sludge is pressed into the clod that moisture content is 15% with filter press, and aqueous too high clod is difficult sizing by excessively soft, and moisture content is too low
Clod cracking will be made broken, then clod pack is placed into the progress of more than three months time from fermenting, promote heavy metal available state to contain
Amount reduction, then will be exposed to the sun under the clod sun from after fermenting or with electrothermal furnace in being dried at 650-700 DEG C, by the part after drying
Clod, which is beaten, is fine into mud powder, 15-20% mud powder is mixed with 80-85% clods as vegetation base soil, clod is used as backsheet during base is native
Material, mud powder, which is located on clod, is used as absorbent material.Thin mud powder is beneficial to preparation and therefrom absorbs moisture content when planting vegetation,
And if only moisture, without mud powder, will be caused to be difficult to be absorbed by root system of plant only with clod, influence plant growth；
（2）Take sediment after metal phosphorizing processing from phosphoric acid, the steel tank of zinc oxide processing, sediment is placed three
More than individual month time was carried out from fermentation, then will be exposed to the sun under the sediment sun after fermenting, and was used as vegetation chemical fertilizer, phosphorating treatment
Substantial amounts of P elements are rich in sediment afterwards, plant absorption can be supplied as phosphate fertilizer, in the present invention, are made after partial sludge processing
For dispensing, coordinate soil prepared by the first step to use, reach that many-sided multi-angle processing, using the effect of sludge, makes each several part dirty
Mud
（3）By step（1）The vegetation base soil and step of preparation（2）The vegetation of preparation mixes to obtain final product vegetation with chemical fertilizer
With soil, wherein vegetation is 0-10% with fertilizer amount, and the consumption of chemical fertilizer is determined according to the vegetation type of middle finger.
The invention provides remaining sludge after a kind of metallic iron acidification to prepare the native method of vegetation, by by metal
The sludge of heterogeneity that different step is remained in iron processing procedure is handled, and preparing can be with planting mud used in vegetation
Soil, will not only be polluted to environment, and the growth of the element also to plant such as the phosphorus being rich in has facilitation, is truly realized
Waste harmless treatment and the effect utilized.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
