Abstract
The invention discloses alkaline organic fertilizer produced by abandoned salt slurry of a chloro-alkali plant and a production method thereof. The method comprises the following steps: abandoned salt slurry is mixed with sedge peat for composting modification after the abandoned salt slurry of the chloro-alkali plate is subjected to primary drying and crushing; and then urea, lemery, borax and other effective ingredients in fertilizer are evenly mixed with one another, and are granulated, dried and packaged to obtain the alkali organic fertilizer used for acid soil. Through using effective nutritive elements of the salt slurry, with scientific treatment and reasonable matching, the abandoned salt slurry of the chloro-alkali plant can be completely digested so as to change waste into valuable , thereby according with national conditions of economic development, namely energy conservation, discharge reduction and recycling economy. The method has the advantages of mature and simple process, low investment and low cost, and the product can regulate acid soil in southern area.
Description
Technical field
The present invention relates to mixed organic manure and production method thereof, specifically is that a kind of abandoned salty mud of chlor-alkali plant that utilizes is produced alkalescent fertilizer and production method thereof.
Background technology
The domestic used crude salt of chlor-alkali enterprise, the salt slurry amount of generation is more, and national caustic soda production reached more than 1,700 ten thousand tons in 2007, and the discharging salt slurry reaches more than 120 ten thousand tons.According to investigations, the salt slurry of national most of chlor-alkali enterprise is throws aside stacking, not only causes the pollution of environment, and the waste of resource also takies a large amount of places, and the alkalescence of salt slurry is big, destroys soil and phreatic acid base equilibrium, the health that also directly threatens people simultaneously.The main component of salt slurry is silicon, calcium, magnesium, also has trace elements such as a spot of zinc, boron, iron, manganese simultaneously.The domestic a large amount of reports that once had with salt slurry extraction sal epsom, as number of patent application 95111658.4 " utilizing chlor-alkali plant waste residue salt slurry to produce the technology of sal epsom ", but extraction cost is high and product price is low, and also has a large amount of secondaries to discharge the waste residue generation, can't obtain promotion and application; Number of patent application 200610017442.2 is " making methods of a kind of boiler spent smoke desulfurizer using salt mud ", because salt slurry alkalescence is big, the alkaline flue gas that produces produces corrosion to boiler plant easily, and only is applicable to that furnace temperature is lower than 1000 ℃ medium and small boiler, also is difficult to be applied; Also have to be used for making cement, but utility value is low, the alkalescence of salt slurry is big, and conformability is also relatively poor.More than the processing patent and the method for abandoned salty mud of alkali-chloride factory all is difficult to all digest chlor-alkali plant depleted salt slurry.Domestic also have a similar report, be to utilize the alkaline residue of soda factory to produce acidic soil conditioner, as: number of patent application is 200610035807.4, " a kind of method of utilizing soda-manufacturing waste residue and municipal sludge to produce acid soil conditioner " mainly is with monoammonium phosphate modification and the acidic soil conditioner that ferments and make through the urban sewage sludge compost of unslaked lime processing with the alkaline residue of soda factory; The patent No. is 03140471.5, and " utilizing the method for soda-manufacturing waste residue production particulate state fertilizer " utilizes the alkaline residue of soda factory to add the monoammonium phosphate modification, adds to add a kind of fertilizer that stone flour, urea etc. are made; These two patents all are to come the modification alkaline residue with monoammonium phosphate, and the price one tunnel of monoammonium phosphate soars in recent years, make patented product price height, are unfavorable for market competition and popularization.
