Abstract
Provided is a method for preparing vegetation soil by utilizing residual sludge after metallic iron acidizing. By treating residual sludge with different ingredients in different steps of metallic iron treatment process, soil for vegetation planting can be prepared, not only is environmental pollution avoided, but also rich elements such as phosphorus can achieve the effect of promoting plant growth, and the effect of harmless treatment and utilization of waste is achieved genuinely.
Description
Technical field
The present invention relates to environmental technology field, after being specifically related to a kind of metallic iron acidification, residual mud prepares the method for vegetation soil.
Background technology
The mud that the city of day by day increasing sharply, Industrial Waste Water Treatments factory produce oneself become serious environmental pollution hidden danger, and become new environmental pollution improvement's difficult point.General sewage plant sludge processing method mainly contains dehydration, modification, mummification etc., and method of disposal mainly contains fills out sea, landfill, Land_use change, building materials, burning etc., and the process of above-mentioned sewage plant sludge is the precondition of above-mentioned sludge treatment.The mud of the generation after particularly electroplating acidification is difficult to process more, once arbitrarily discharge, will cause very large pollution, and existing landfill method floor space is large, must Anti-seeping technology be made, also will build methane recovery system and leakage water treatment plant, easily underground water and surrounding air be polluted, resource can not be recycled, and there is mobility due to mud, independent landfill difficulty is very large, for populous, China of cultivated land resource growing tension, is more and more difficult to implement; Land_use change is by the scope of application and seasonal restriction, be difficult to formation scale, and easily cause the secondary pollution of environment, the acceptance level of the common people is also low, mud particularly containing heavy metal more can not carry out Land_use change, and these mud can not be directly used in plantation vegetation.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present invention provide a kind of metallic iron acidification after residual mud prepare the native method of vegetation.
The technical solution that the present invention adopts is: after a kind of metallic iron acidification, residual mud prepares the method for vegetation soil, and described residual mud comprises acidification and remains mud and metal phosphorizing process postprecipitation thing, comprises the following steps:
(1) from the stone cistern of hydrochloric acid and sulfuric acid acidation metallic iron, obtain acidification and remain mud, acidification is remained mud filter press and be pressed into clod, clod is packed more than three months time of placement carry out from fermentation, to be exposed to the sun under the clod sun after fermentation or dry at 650-700 DEG C with electrothermal furnace again, part clod after oven dry is beaten and is fine into mud powder, 15-20% mud powder is mixed with 80-85% clod as vegetation base soil;
(2) from phosphoric acid, zinc oxide process steel tank take metal phosphorizing process postprecipitation thing, sediment is placed more than three months time carry out from fermentation, then by from fermentation after the sediment sun under be exposed to the sun, as vegetation chemical fertilizer;
(3) vegetation chemical fertilizer prepared by vegetation base soil and the step (2) step (1) prepared is mixed to get end product vegetation soil, and wherein vegetation fertilizer amount is 0-10%.
In described step (1), filter press is pressed into the moisture content of clod is 15%.
In described step (1) vegetation base soil, clod is as primer, and mud powder is positioned on clod as absorbent material.
The invention has the beneficial effects as follows: after the invention provides a kind of metallic iron acidification, residual mud prepares the method for vegetation soil, processed by the mud of the heterogeneity that different step in metallic iron processing procedure is remained, preparation can be used on the upper earth used of vegetation plantation, not only can not to environment, and the elements such as the phosphorus be rich in also have facilitation to the growth of plant, have really accomplished the effect of refuse harmless treatment and utilization.
Detailed description of the invention
The residual mud generated in metallic iron processing procedure comprises acidification and remains mud and metal phosphorizing process postprecipitation thing.
After metallic iron acidification, residual mud prepares a method for vegetation soil, comprises the following steps:
(1) from the stone cistern of hydrochloric acid and sulfuric acid acidation metallic iron, obtain acidification and remain mud, acidification is remained mud filter press and be pressed into the clod that moisture content is 15%, moisture too high clod will be crossed and softly not easily to shape, and the too low clod cracking that will make of moisture content is broken, again clod is packed more than three months time of placement carry out from fermentation, promote that heavy metal bio-available Zn concentration reduces, to be exposed to the sun under the clod sun after fermentation or dry at 650-700 DEG C with electrothermal furnace again, part clod after oven dry is beaten and is fine into mud powder, 15-20% mud powder is mixed as vegetation base soil with 80-85% clod, in base soil, clod is as primer, mud powder is positioned on clod as absorbent material.Thin mud powder, when planting vegetation, will be conducive to preparation and therefrom absorb moisture content, and iff only adopting clod not add mud powder, moisture will be caused to be difficult to be absorbed by root system of plant, affect plant growth;
(2) from phosphoric acid, zinc oxide process steel tank take metal phosphorizing process postprecipitation thing, sediment being placed more than three months time carries out from fermentation, be exposed to the sun under the sediment sun after fermentation again, as vegetation chemical fertilizer, a large amount of P elements is rich in phosphorating treatment postprecipitation thing, can be used as phosphate fertilizer for plant absorption, in the present invention, as batching after this partial sludge process, the earth coordinating the first step to prepare uses, reach the effect that many-sided multi-angle process utilizes mud, make each several part mud
(3) vegetation chemical fertilizer prepared by vegetation base soil and the step (2) step (1) prepared is mixed to get end product vegetation soil, and wherein vegetation fertilizer amount is 0-10%, and the consumption of chemical fertilizer decides according to the vegetation type of middle finger.
After the invention provides a kind of metallic iron acidification, residual mud prepares the method for vegetation soil, processed by the mud of the heterogeneity that different step in metallic iron processing procedure is remained, preparation can be used on the upper earth used of vegetation plantation, not only can not to environment, and the elements such as the phosphorus be rich in also have facilitation to the growth of plant, have really accomplished the effect of refuse harmless treatment and utilization.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
