Abstract
The invention relates to waste water sludge type cement, which is mainly mixed by cement and a product of waste water sludge. The product of waste water sludge is prepared by the method that waste water sludge, and acetylene gas slag or lime sludge, or waste water sludge, acetylene gas slag or lime sludge, bauxite slag, phosphogypsum or desulfurization gypsum, mineral slag and fly ash are in certain proportion with proper water to be added into a mixing and molding machine so as to be processed into nodules, after the nodules are naturally air dried into raw meal nodules, the raw meal nodules are dried and roasted, and the product of waste water sludge is prepared. Then the product of waste water sludge and cement clinker are mixed together in certain proportion to be ground into powder, that is, the waste water sludge type cement; or the product of waste water sludge is ground into powder, then the powder is mixed together with cement, and the waste water sludge type cement is formed. The product of waste water sludge can be mixed with pure clinker cement, and can be also mixed with other commercial cement. The method can process the waste water sludge, which is discharged from the waste water processing factories and is difficult to be processed, into high quality cement that has advantages of large demand, less investment, high wear-resisting strength, good frost resistance performance, small dry shrinkage performance, being favorable for environmental protection and reducing cost.
Description
Technical field
The present invention relates to a kind of new cement, particularly a kind of a kind of sewage water body refuse type cement that utilizes the sewage water body refuse of sewage work's discharge for raw material production, and, belong to environmental protection or cement field for it provides practical preparation method.
Background technology
The sewage water body refuse of sewage work is with the gravity simmer down to waste residue that mechanize dehydration etc. discharges of advocating peace with sanitary sewage, it contains the required nitrogen of growth and development of plants, phosphorus, potassium and keeps the various trace elements of plant normal growth growth and the organic matter of the structure of improving the soil, and also contains the organic poison of pathogenic micro-organism, parasite (ovum), heavy metal and some difficult degradation simultaneously.Water ratio develops very difficult 70～80%.
In order to handle these mud, lot of domestic and international people has thought many ways, and its method mainly is that mud is carried out landfill, stacks, jettisons ocean, burning, compost treatment etc.In age, there are every year 200000000 tons of sludge discharges to occur in Future in China.Landfill, stack, be the main method of handling mud at present.The treating processes of this method is simple, but needs a large amount of places and freight charges, and ground need be made anti-drain process, in order to avoid polluted underground water and giving an offensive smell.In addition, the soil that is fit to filling reduces year by year, and in EPA is added up 16 years from now on, 6500 landfill yards of the U.S. will have 5000 to close.The state that has has not had the place can be for stacking mud.For jettisoning the ocean, though be a kind of convenience and economic treatment process, this method can endanger Marine ecosystems and human foods chain, can cause the harm in the global range, should forbid.For the burning disposal method, obviously there are burning facility and working cost costliness, waste gas can cause topsoil, neither good method.For composting treatment method, be the organic waste in the mud to be decomposed by means of microorganism, but heavy metal in the sewage sludge and organic pollutant content have become the critical limitation factor that the mud soil utilizes, often contain heavy metal and many kinds of toxic organic compounds such as a large amount of copper, nickel, cadmium, lead, zinc, mercury in the mud, if the farmland midium or long term uses, can cause soil pollution, they enter human body by food chain again after by crop absorption, thereby influence HUMAN HEALTH.According to the pertinent data statistics, Japanese mud land and ocean landfill account for 62.7% at present, and agricultural greening accounts for 24.9%, and other disposal account for 12.4%, and German mud landfill accounts for 80%, and agricultural greening accounts for 8%, burn and account for 8%, and compost accounts for 4%.U.S.'s mud landfill accounts for 35%, burns and accounts for 15%, and agricultural or other soil utilizations account for 49%, and other disposal account for 1%.In sum, up to the present, yet there are no the report of other better environmentally friendly method for sludge treatment.
Summary of the invention
The objective of the invention is in order to overcome the weak point of the above-mentioned existing the whole bag of tricks that sewage water body refuse is handled, provide a kind of can will pile up like a mountain reluctant again sewage water body refuse is turned waste into wealth, produce that demand is huge, less investment, abrasive wear resistance height, good frost resistance, drying shrinkage are little, not only helped environmental protection, but also the sewage water body refuse type cement that can reduce production costs.
Another object of the present invention is to provide a kind of preparation method of practicality for producing qualified sewage water body refuse type cement.
Sewage water body refuse type cement of the present invention, its main component is mixed by 70%～95% cement and 30%～5% sewage water body refuse product.
Parts by weight of raw materials in the described sewage water body refuse product is: 1～3 part of 2～7 parts of sewage water body refuses, acetylene gas slag or lime mud.
