Abstract
The present invention relates to the recovery and utilization technology of the wet filter mud of cane sugar factory refuse.Take in the wet filter mud that undried is handled, to add amendment, make through mixing reaction that physical behavior is splendid to be powdery or granular mixing fertilizer, and then add an amount of nitrogen, potassium, rare earth element, plant-growth regulator and make binary, the Nitrogen, Phosphorus and Potassium that contains rare earth element or plant-growth regulator.Thereby make the wet filter mud that is sposh shape stink change over the fertilizer that powdery or particulate state do not have stink, solved a large amount of wet problem of environment that filter mud causes, have very big economic benefit and social benefit.
Description
The present invention relates to the recovery and utilization technology of the wet filter mud of cane sugar factory refuse, this technology is applicable to makes mixing fertilizer and composite fertilizer with filtrated sludge of cane sugar refinery.
Cane sugar factory (sulfurous method or carbonatation process) all will be discharged a large amount of wet filter mud waste materials, the output of its wet filter mud is about 3%～5% of sugarcane-squeezing amount, the sugar refinery of pressing 2000 tons of sugarcanes one day has 60～100 tons of wet filter muds to discharge every day approximately, and the whole nation has wet filter mud 200～3,000,000 tons every year approximately.Wet filter mud contains multiple element and a large amount of organic substances such as rich in protein and nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, is a kind of good organic fertilizer.But because wet filter mud water content is bigger, is the sposh shape and volatilizes the extremely difficult smell of smelling, physical behavior is poor, brings very big inconvenience to utilization.So that domestic and international many cane sugar factories are the wet mud waste of major part, or water dashes and enter rivers, or dig large-area melt pit and bury, and if things go on like this, cause that BOD and the COD in the water body increases, and cause serious environmental to pollute.
For this reason, the object of the present invention is to provide and the wet filter mud of cane sugar factory handled to make physical behavior good, do not have difficult olfaction, and the organic and inorganic that is easy to use mixing is fertile and the production method of various composite fertilizers, fundamentally to solve the problem that wet filter mud pollutes.
The key of the technology of the present invention solution is: utilize wet filter mud composting material, just must solve because water content causes physical behavior poor greatly, and bad-smell problem.Major technology feature of the present invention in view of the above is:
One, direct adding can change one or more amendments of wet filter mud physical behavior in the wet filter mud of handling without super-dry, and control pH value is 6～7, through mixing reaction, the process stacking is handled or is handled without stacking, and promptly can be made into to be powdery or the good organic and inorganic mixing fertilizer of particulate state physical behavior.Described amendment is: calcium superphosphate, fused(calcium magnesium)phosphate, thomas phosphate, defluorinated phosphate, various fuel ash, bicarbonate of ammonia, ammonium sulfate, volatile salt, ammonium phosphate sulfate, ammonium phosphate, Calcium hydrogen carbonate, sugarcane chaff, lime carbonate, lime and precipitated superphosphate behind normal superphosphate, double superhosphate, double superphosphate, ammoniated superphosphate, the adding alkali works ammoniated mother sludge waste residue.
Owing to the adding of above-mentioned amendment reacts, the reaction heat that reaction generates raises temperature of charge, partly water evaporates effusion in the filter mud that will wet, and having partly in the reaction again, free-water generates corresponding crystal water, thereby reduced the moisture content existence, changed the physical behavior in the wet filter mud.In addition, along with the increase of pilling up time, above-mentioned reaction process is just complete more, makes the physical behavior of material better, and stink disappears so that finally obtain loose more, dry physical behavior is splendid, the powdery that can directly use or granular organic and inorganic mix fertile
They are two years old, system composite fertilizer: can mix at the organic and inorganic of above-mentioned gained as required and add the required trace element of an amount of nitrogen, phosphorus, potassium and some plants, rare earth element on the fertile basis, reach somatomedin, further make the various binary, the Nitrogen, Phosphorus and Potassium that contain trace element, rare earth element or somatomedin.
So far, because the realization of the technology of the present invention, the wet filter mud of a large amount of pollutents that cane sugar factory is discharged obtains handling, and organic and inorganic mixing fertilizer of being made and binary, Nitrogen, Phosphorus and Potassium have splendid physical behavior, not having the wet original stink of filter mud, is a kind of good organic-inorganic fertilizer.Again because the technology of the present invention is that the wet filter mud that undried is handled is directly handled, thereby a large amount of energy consumptions, fund, equipment have been saved, be a kind of less investment, method simple to operate, thereby solved wet filter mud and caused environmental pollution problems, turn waste into wealth, tangible economic benefit and social benefit are arranged.
