Abstract
The invention belongs to a sludge treatment method, and more specifically relates to a method for treating sludge produced by treatment of high-concentration organic wastewater. The method is characterized in that cement raw material for replacing sludge is measured according to the chemical composition of wet sludge produced by the treatment of high-concentration organic wastewater under design requirements of taking silicate or aluminate as main material; the sludge and the cement raw material are mixed well and prepared into raw material sticks or raw material balls; and the sludge is subjected to harmless treatment by utilizing the high-temperature high-heat environment of a cement-sintering system. The method has unique technical and economic advantages and meets the requirements of environmental protection.
Description
One, technical field:
The invention belongs to a kind of method of sludge treatment, be specifically related to a kind of treatment process of administering the mud that high concentration organic sewage produces.
Two, background technology:
Administer the mud that sewage produced, the most existing treatment process, final dissolving must take certain place and space, the land of the mud two kinds of basic modes of dissolving: a kind of concentrating promptly is called as the processing mode of landfill; A kind of agricultural, in fact be the processing mode that a kind of land disperses dilution.Although burn the quality and the volume that can greatly reduce mud, its resistates (lime-ash) still need suitably be handled with land and dissolve.Just because of this, sludge treatment is faced adverse conditions, and sludge of sewage treatment plant is handled problems especially serious.
Particularly not only to administer the sewage difficulty big for high concentration organic sewage, and administering mud that high concentration organic sewage produced, to contain poisonous objectionable impurities too high, should not make agricultural fertilizer and use, and simply buries to fill out and cause the harm of secondary pollution bigger.Utilize application number to be: 200910009174.3-produces the flocculation agent processing mud that high concentration organic sewage produced of the method preparation of poly-ferric aluminum silicate sulfate from rare earth with containing rare earth mud and ion dust mud contaning, though it is very high to contain poisonous objectionable impurities, but make the building materials prepared using according to the chemical ingredients of this mud, can avoid above-mentioned harm.
Three, summary of the invention:
The objective of the invention is the above-mentioned defective that exists at prior art, intend providing the treatment process of the mud that a kind of improvement high concentration organic sewage that is different from the prior art scheme produced.The present invention utilizes cement firing system high temperature, high thermal environment harmless treatment mud fully according to the chemical ingredients of this mud, has unique technique, economic advantages, and compliance with environmental protection requirements.
For realizing purpose of the present invention, the technical scheme of being taked is as follows:
To utilize application number to be: 200910009174.3-produces the flocculation agent processing mud that high concentration organic sewage produced of the method preparation of poly-ferric aluminum silicate sulfate from rare earth with containing rare earth mud and ion dust mud contaning, hygroscopic state sewage sludge after box press filtration (water content is 20%-60%) is cement raw material as an alternative, prepare burden with other cement raw material again through grinding, mix and make raw material rod or raw material ball, send into and burn till grog in the cement kiln., be main grog design requirements promptly, press 5%-20% metering mud place of cement material quantity by silicate or aluminate earlier according to the chemical ingredients of handling the mud that high concentration organic sewage produced.Again mud and the cement raw material through grinding are prepared burden, mix through stirrer, make raw material rod or raw material ball with extrusion shaping machine, directly send into cement kiln with 1200-1300 ℃ of burning, make and handle the dioxin decomposition that contains in the mud that high concentration organic sewage produced, make the organic matter of the processing mud that high concentration organic sewage produced finish burning and burn till grog.In addition, because La
2O
3-CeO
2The existence of mixed rare-earth oxide can obviously improve cement clinker strength, improves cement clinker output simultaneously, reduces grog energy consumption and production cost.
The mud that above-mentioned processing high concentration organic sewage is produced refers to utilize application number to be: 200910009174.3-produces the mud of the high density pharmacy organic sewage that the flocculation agent of the method preparation of poly-ferric aluminum silicate sulfate from rare earth handles, the mud of high concentration agricultural chemical organic sewage, the mud of high-concentration dye-printing organic sewage, the mud of high poly-oilfield produced water with containing rare earth mud and ion dust mud contaning.
Compared with prior art the present invention has following unusual effect:
1, utilize application number to be: 200910009174.3-produces the flocculation agent processing high concentration organic sewage of the method preparation of poly-ferric aluminum silicate sulfate from rare earth with containing rare earth mud and ion dust mud contaning, high concentration organic sewage is administered at all, and made mud obtain utilization as producing cement raw material.
2, the La that contains in this mud
2O
3, CeO
2Component plays oxidation, katalysis in producing grog technology, shortened the grog firing time, has reduced production cost; In addition, because La
2O
3, CeO
2The chemical reaction of grog is fired in participation, has changed the molecular structure of cement clinker, has improved cement clinker strength, output.
3, utilize moisture, inorganics component and organic combustiblematerials energy in this mud, can the conserve water resource, can reduce again and produce the consumption of cement natural mineral.
4, utilize 1200-1300 ℃ of high temperature of calcining cement clinker, effectively the organism in the after-flame mud is eliminated organic pollution, utilizes absorption and the solid pollution of melting effect elimination heavy metal element of rare earth silicon aluminium mineral material to heavy metal element simultaneously.
5, utilize existing cement clinker production technique just can realize administering the handling problem of the mud that high concentration organic sewage produced.
