Abstract
The invention relates to the technical field of waste tin sludge treatment, in particular to a method for preparing a bio-organic fertilizer from waste tin sludge. The invention adopts a main technical scheme comprising the following steps of: treating tin sludge through water washing, electrolysis and biological fermentation sequentially, namely separating part of metal precipitate mainly through water washing and then separating part of metal through electrolytic reduction; and treating the residual non-metal parts by using a biological reagent to obtain the bio-organic fertilizer. The method for preparing the bio-organic fertilizer from the waste tin sludge has the advantages of low production cost, high profit and simple process and production equipment. Particularly, the bio-organic fertilizer prepared by the method comprises a moisturizing factor and a great variety of nutritional components and can be increased and supplemented continuously without causing soil acidification.
Description
Technical field
The invention belongs to useless tin mud processing technology field, particularly a kind of method with preparing bio-organic fertilizer from waste tin sludge.
Technical background
Because tin has a lot of good character, the scruff that produces in the industry is normally directly recycled; For the useless scruff of purifying, people can utilize solder dross reducing agent earlier scruff to be handled, because the scruff great majority are oxide compounds (stannic oxide or tin protoxide) of tin, small part be tin and copper or its minute impurity compound, reductive agent is exactly that the oxide compound of tin and compound thereof are carried out a redox or replacement(metathesis)reaction, tin is restored, produce other simultaneously and a spot ofly can not be fused to material in the tin liquor (usually just organism such as some carbide and phosphorus nitrogen), residue abbreviation tin mud through solder dross reducing agent reduction back.Tin mud generally reclaims, and also not well, creates the method for utilizing tin mud of higher economic worth at present.
Summary of the invention
The invention provides a kind of not only with low cost, be easy to realize that and technology and production unit are simply used the method for preparing bio-organic fertilizer from waste tin sludge.
To achieve the above object, technical scheme of the present invention is:
A kind of method with preparing bio-organic fertilizer from waste tin sludge comprises washing step, electrowinning process and biologic treatment process;
The concrete steps of preparation are:
Steps A, elder generation are transferred to tin mud in the reaction tank, then add entry in settling tank, and water consumption is recently calculated by weight, and the ratio of tin mud and water is 5%～20%;
After step B, the abundant stirring, left standstill 12～48 hours;
Step C, move away precipitated metal by reaction tank bottom;
Step D, will remain in the cement admixture in the reaction tank, and continue dilute with water and stir for 5～6 times;
Step e, lay electrolyzer in the settling tank and carry out electrolysis;
After step F, the electrolysis fully, the electrolyzer that is adsorbed with metal is removed; If on the male or female rod of master metal absorption electrolyzer;
Step G, drop into biological reagent in the reaction tank and carry out biological fermentation, normal temperature bottom fermentation at least 48 hours;
Step H, the mixture that ferments among the step G is carried out solid-liquid separation, liquid packaging becomes liquid biological organic fertilizer, is packaged into solid-state biological organic fertilizer after the solid oven dry.
Wherein, among the described step G, the injected volume of used biological reagent is to throw in 100～400mg biological reagent in the cement admixture after the electrolysis per ton.
Described biological reagent is the one or more combination thing in milk-acid bacteria, Phosphoric acid esterase or the cereuisiae fermentum.
Described milk-acid bacteria is the one or more combination thing in streptococcus acidi lactici, dimethyl diketone streptococcus acidi lactici, cheese suis, streptococcus thermophilus, the bright beading mattress of lactic acid or the leuconostoc oenos.
Described Phosphoric acid esterase is the one or more combination thing in tyrosine-specific Phosphoric acid esterase, dual specificity phosphatase enzyme or the lipid Phosphoric acid esterase.
The present invention utilizes washing, electrolysis and biological fermentation that tin mud is handled, not only contain micro-harmful heavy metal lead, cadmium, mercury etc. in the tin mud, and to contain for electronic solder be useful metallic tin, silver, copper etc., and other are nonmetal and multiple machine essence arranged also to contain carbon, nitrogen, phosphorus etc. simultaneously.The present invention washes with water processing such as useful metal tin, silver, copper and can precipitate and separate come out, and heavy metals such as back lead, cadmium, mercury are handled in washing; Can utilize electrolytic reduction to separate and carry out recycling; For non-metallic part, then can utilize biological reagents such as milk-acid bacteria, Phosphoric acid esterase or cereuisiae fermentum to handle, because the non-metallic part in the non-tin mud mostly is organic essence and organic acid etc., biological reagent can be decomposed into it nutritive substances such as more higher leveled vitamin b6 usp protolysate and carbohydrate, thereby the tin mud that will give up is finally made full use of as organic fertilizer.
Not only production cost is cheap in the present invention, profit is high, and the prepared biological organic fertilizer huge market demand that forms, and its technology and production unit are simple; Be a kind of relatively actual processing and utilize method, this method not only can create considerable economic value, but also has eliminated waste residue, administered environmental pollution; Especially the biological organic fertilizer made of the present invention contains the insulation factor and multiple nutritional components; sustainable getting fat is topdressed; and can not cause acidification; can make soil be difficult for forming lump; dig well, good application of mixed fertilizers and continue to append this product, continue to cultivate and help secular environment protection and soil conservation.According to statistics; the biological organic fertilizer that uses the present invention to make; it can not only be the increase of production 20%～30% of fruit; and the sugariness of fruit can improve 2～3 degree; especially one deck wax shape protective membrane can produced by the plant leaf surface of fertilising object; can effectively prevent to damage by worms, also avoid tradition to spray insecticide and bring the drawback of negative effect to people simultaneously in order to prevent to damage by worms.
