Abstract
The present invention relates to a method for treating deserts or sandy lands by urban organic waste, which comprises the following steps: pulverizing water-containing sludge of urban sewage treatment plants or municipal solid waste; diluting the pulverized materials to mixture which contains 40 to 60 % of solid matter; treating the mixture by quick lime of which the use quantity is 20 to 30% of the treated sludge; stirring the mixture; killing viruses and partial bacteria under the heat release and alkali action of the quick lime in water so as to keep beneficial bacteria (sludge treated by the process has the pH value about 12); adding acidic materials for stirring and neutralizing to pH about 8 to 10 to obtain pasty materials; obtaining a material of the present invention for treating organic contaminant after the processes of granulation and package. The material for treating organic contaminant is mixed with tree seeds and grass seeds to be directly applied to deserts or sandy lands.
Description
Invention field
The present invention relates to the method for utilizing city organic waste handled thing to defend and control sand.
Technical background
The municipal sewage plant has produced a large amount of mud, and these mud, will certainly pollute environment if be disposed in the environment owing to contain toxic heavy metal ion and other objectionable impurities, even near the resident's heavy metal poisoning causing.Equally, along with the sharp increase of urban population, the domestic waste bulk deposition can not get effective processing, though processing has been taked to bury in some place, because the many composition degradation speeds in the rubbish are slow, many decades even last a century can not degraded fully.Therefore, also there are not a kind of very effective municipal sludge and waste disposal method at present.
Summary of the invention
The objective of the invention is to solve above-mentioned problems of the prior art, the organic waste handled thing will be obtained after municipal sludge and the domestic rubbish disposal, again this organic waste handled thing is used to defend and control sand, thereby thoroughly solved the pollution problem of municipal sludge and domestic refuse, proposed a kind of new departure for the improvement in desert again simultaneously.
The object of the present invention is achieved like this: the water-containing sludge of municipal sewage plant is handled with unslaked lime, the consumption of unslaked lime is the 20-30% of handled mud weight, stir, by the heat release of unslaked lime in the presence of water and alkalescence effect (so the pH of the mud of handling is generally about 12) virus and part bacterium are killed, beneficial bacteria obtains keeping, add acidic substance then, stir, be neutralized to about pH 8-10, so the material that obtains becomes the mucilage shape, granulation again, packing promptly obtains organic pollutant handled thing of the present invention.
Wherein said mud generally contains the water of 60-80wt%, and all the other are solid.
Wherein said acidic substance can be mineral acids, example hydrochloric acid, and sulfuric acid, or their salt, as their weak base salt, or organic acid.
In addition, method of the present invention also can be used for handling urban life and draws rubbish, and domestic waste is crushed to fine particle with pulverizer, and thin up is to the mixture that contains solid matter 40-60%, the 20-30wt% unslaked lime that adds mixture weight then, utilize the heat release of chance water and the alkalescence of unslaked lime, kill virus and part pathogenic bacteria, beneficial bacteria obtains keeping, be neutralized to the about 8-10 of pH with acid then, so the material that obtains becomes the mucilage state, and granulation more promptly makes organic pollutant handled thing of the present invention.
Wherein used acid can be above-mentioned those.
Wherein used pulverizer can adopt disclosed high efficiency processor for urban domestic garbage in the open CN 1214213A of Chinese patent application.This patent is introduced for reference here in full.
Above-mentioned handled thing can add seed, directly is sprinkled into sandy land and desert.
The invention is characterized in, utilize the chance water heat release of unslaked lime, kill virus and unwanted bacteria in mud and the rubbish, help beneficial bacteria accelerates multiplication at high temperature simultaneously, accelerate organic degraded, make inorganics become nutritious organic fertilizer; Add the acid neutralization,, make it more help plant-growth, and the handled thing that obtains becomes the mucilage shape, be easy to granulation, and help anchoring on sandy land or the desert, unlikelyly blown off by dust storm in order to avoid cause the soil property alkalization, extremely beneficial for the improvement desert.And handled thing of the present invention is solid matter, can directly pack after the granulation, is easy to be transported to sandy land and desert region, solved the secondary pollution problem of municipal wastes and mud again.Utilize method of the present invention, can solve municipal wastes and mud bulk deposition in the countryside, the problem that can not get dealing carefully with provides effective means for administering the desert again simultaneously.
Through test, sneak into arbor, shrub and grass seed at this organic pollutant handled thing, directly be sprinkled into sandy land, nursing such as do not water.As a result, the normal rudiment of plant, growth, and also arbor, shrub and vegetation growth are very vigorous.
Embodiment
Embodiment 1
With moisture about 70% 10L mud of municipal sewage plant in being provided with the bucket of whipping appts with 2 liters of unslaked limes processing, stir, by the heat release of unslaked lime in the presence of water and alkalescence effect (so the pH of the mud of handling is generally about 12) virus and part bacterium are killed, beneficial bacteria obtains keeping, and adds hydrochloric acid then, stir, make to be neutralized to about pH 8-10 that so the material that obtains becomes the mucilage shape, granulation again, pack promptly obtains organic pollutant handled thing of the present invention.
Embodiment 2
Domestic waste is crushed to fine particle with pulverizer for 10 kilograms, thin up is to the mixture that contains solid matter 40-60%, add 4 kilograms of unslaked limes then, utilize the heat release of chance water and the alkalescence of unslaked lime, kill virus and part pathogenic bacteria, beneficial bacteria obtains keeping, be neutralized to the about 8-10 of pH with sulfate liquor then, so the material that obtains becomes the mucilage state, granulation again, pack promptly makes organic pollutant handled thing of the present invention.
Claims (4)
1, a kind of method of utilizing the city organic waste to administer desert or sandy land may further comprise the steps:
Being diluted to the mixture that contains solid matter 40-60% after the water-containing sludge of municipal sewage plant or domestic waste pulverized handles with unslaked lime, the consumption of unslaked lime is the 20-30% of handled mud weight, stir again, by the heat release of unslaked lime in the presence of water and alkalescence effect virus and part bacterium are killed, so the pH of the mud of handling is generally about 12, beneficial bacteria obtains keeping, add acidic substance then, stir, be neutralized to about pH8-10, so the material that obtains becomes the mucilage shape, granulation again, packing promptly obtains organic pollutant handled thing of the present invention;
Above-mentioned organic pollutant handled thing is used to administer desert or sandy land.
2, according to the process of claim 1 wherein that described mud generally contains the water of 60-80wt%, all the other are solid.
